The Chinese space tracking ship "Yuanwang 3" has returned to the Jiangnan Port of Nanjing in East China's Jiangsu Province after successfully completing its mission with China's first experimental spacecraft "Shenzhou." The other three ships, Yuanwang 1, 2 and 4, returned from their missions earlier. During their 259-day voyage, the four ships traveled some 62, 000 nautical miles and experienced some heavy seas while tracking and communicating with the "Shenzhou" for a total of 150 minutes. (People's Daily) --- note the December 12 news (all 4 ships return) on this site is not precise.

Flight controllers continue to manage the charging of the batteries on the Zarya module and are watching over other systems on the station. Electrical power management continues to be the focus, with the Station operating on the power generated by four of six batteries inside Zarya. Batteries 1 and 2 remain disconnected from the electrical bus. Over the next two weeks, controllers plan to recharge battery 1 and place it in a backup, or standby mode, to be used if necessary. The four batteries currently servicing Zarya are providing more than enough power for all ISS systems. Additional Details: here....

Managers continue to manage electrical power through four of six batteries inside the Zarya module, with battery number one currently in full restoration mode through Monday. Following its restoration, which is conducted on all batteries every six months to maximize charging capacity, battery one will be available for use periodically, if necessary.

Unsuccessful ABM test. First end-to-end system test (intercept attempt) using NMD prototype elements (except the IFICS) and range assets to approximate the objective system. The EKV was again successfully delivered by a surrogate booster and separated into the deployment basket. The failure to intercept was directly traceable to the cryogenic cooling system of the EKV, which failed to cool the IR sensors down to their operating temperatures in time because of an obstructed cooling line.

Flight controllers continue to manage electrical power through the batteries inside the Zarya module, recharging four of the six on-board power plants. Battery # 1, which has experienced some problems and will be replaced by Shuttle astronauts later this year on the next mission to the ISS, has been recharged and is currently connected to Zarya's electrical bus while other batteries complete their recharging.

Optical Calibration Sphere Experiment, a 3.5m diameter inflatable sphere built by L'Garde Inc. for calibrating the lasers at the AFRL Starfire Optical Range. The 0.48m long 0.41m diameter OCSE canister was ejected from the JAWSAT stack; 42 seconds later, with the canister clear of the other payloads, the canister door opened and 10 seconds after that inflation of the sphere began. The canister remains attached to the inflated sphere. Once inflated, the sphere's material becomes rigidized

Progress M1 was a modification of the Progress M for the International Space Station. The first such spacecraft was diverted to raise the orbit of Mir. It docked with the unoccupied Mir space station on February 3 at 0802:20 GMT. Burns of its motor to raise Mir's orbit began on February 5 and continued through February 9. Progress M1-1 undocked at 16:33 GMT on April 26 to clear the docking port for Progress M1-2. It was deorbited over the Pacific at 19:27 GMT the same day.

Spanish domestic geosynchronous communications satellite. Stationed at 30 deg W. Positioned in geosynchronous orbit at 30 deg W in 2000. As of 3 September 2001 located at 30.14 deg W drifting at 0.013 deg W per day. As of 2007 Mar 9 located at 30.01W drifting at 0.005W degrees per day.

After four orbits around the Earth the test vehicle was powered by the launcher's upper stage to re-enter the atmosphere for a landing about 1800 km northwest of the launch site. The heat shield was inflated and the IRDT separated from the upper stage. It then passed through the upper atmospheric layers that imposed the highest dynamic pressure, heat flux and acceleration loads onto the system. The IRDT landed inside the predicted area at 54 deg E and 51 deg N near the Kazakhstan border. Unfortunately, a tear occurred in the inflatable shield during descent resulting in a higher velocity and a heavier than expected impact on landing, resulting in some damage to the lower part of the IRDT. The IRDT was collected by helicopter so that the memory unit of the sensor package, with all recorded data, could be analysed. An initial data check confirmed that all experiments in the sensor package worked perfectly.

Spacecraft was injected in very low perigee orbit and reentered. X-ray astronomy satellite. Stage 1 lost control, and separated with the rocket off-course at 75 seconds in the flight. Stage 2 burned correctly and separated at 218 seconds, followed by the third stage burn at 621 seconds. Last signals were received at 20 minutes after launch. ASTRO-E was to have separated from the third stage at 23 minutes, but ended in an orbit with a perigee of only 80 km and an apogee of 410 km. It probably reentered on the first orbit at around 0230 - 0300 GMT somewhere between East Africa and western China.

On an extremely successful mission the space shuttle Endeavour deployed the 61 metre long STRM mast. This was a side-looking radar that digitally mapped with unprecedented accuracy the entire land surface of the Earth between latitudes 60 deg N and 54 deg S. Sponsors of the flight included the US National Imagery and Mapping Agency (NIMA), NASA, and the German and Italian space agencies. Some of the NIMA data would remain classified for exclusive use by the US Department of Defense.

Geosynchronous communications satellite for the ACES consortium (PSN of Indonesia, PLDT of the Phillipines, Lockheed Martin, and Jasmine of Thailand). The satellite had two large 12-m diameter L-band antennae for cellular telephone relay. Stationed at 123 deg E. Positioned in geosynchronous orbit at 123 deg E in 2000. As of 5 September 2001 located at 122.97 deg E drifting at 0.023 deg W per day. As of 2007 Mar 10 located at 123.10E drifting at 0.005W degrees per day.

The first "flycast maneuver" trim burn was completed without a hitch by members of the Endeavour crew early Sunday. A little later, the Payload Operations Center reported that the Shuttle Radar Topography Mission had successfully mapped 7.64 million square miles as of very early Sunday morning.

NEAR finally entered orbit around Eros on Valentine's Day, 2000. Orbit insertion was at 15:34 GMT into a 323 x 370 km initial orbit with a period of 27 days. The renamed NEAR-Shoemaker probe moved into a 100 x 200 km orbit around Eros on April 2 at 02:00 GMT. NEAR returned spectacular detailed pictures of the surface over the next several months. Studies were made of the asteroid's size, shape, mass, magnetic field, composition, and surface and internal structure.

With growing confidence that fuel-saving measures onboard Endeavour will permit the radar mapping mission to run its full duration, flight controllers and crew members today marked the mission's mid-way point. "We're almost there," stated Milt Heflin, NASA's Deputy Chief Flight Director. Additional Details: here....

As the International Space Station continues to orbit the Earth in good shape, its automatic docking system was tested twice this week without problems in an effort to verify that the system is ready to support the rendezvous with the Zvezda service module this summer. Meanwhile, Space Shuttle and Station managers formally approved the Shuttle visit to the Station to outfit Zvezda for occupancy by the first resident crew. Additional Details: here....

Provided geosynchronous communications services for the Space Communications Corporation of Japan. Carried 23 Ku-band and 6 Ka-band transponders, and was equipped with a Marquardt R4D apogee engine and XIPS ion propulsion stationkeeping system. Stationed at 162 deg E. Positioned in geosynchronous orbit at 162 deg E in 2000. As of 4 September 2001 located at 162.01 deg E drifting at 0.003 deg W per day. As of 2007 Mar 9 located at 161.98E drifting at 0.004W degrees per day.

Following yesterday's decision by mission managers to extend mapping operations, Endeavour's astronauts are set to continue collecting data until 5:44 a.m. Central time Monday. At that point preparations will begin to stow the 200-foot-long mast for the remainder of the mission. This 9-hour extension allows for almost 100 percent of the planned coverage of the Shuttle Radar Topography Mission. Additional Details: here....

Endeavour's astronauts are looking forward to using one more small bonus in mapping operations time. They were given an additional 10 minutes, bringing the total to nine days, 18 hours and 10 minutes. The additional minutes have been added to allow one more mapping pass across Australia, rather than turning off the radar just as the spacecraft approaches the nation's coastline.

Progress M1-1: This new freighter type was launched to Mir from Baykonur on 1.02.2000 at 0647UTC. The approach and docking in the automatic mode by the system Kurs was successfully accomplished on 3.02.2000 at 0802UTC. During this operation the tension in mission control (TsUP) in Korolyov was very great because if this operation would fail the crew of the 28th Main Expedition to Mir should start to Mir on 17.02.2000, so earlier than planned to control the docking of Progress M1-1 from inside Mir in the manual mode by the system TORU.

Progress-M42: This old freighter had to free the docking port for the Progress M1-1 and when it was clear that all systems on board of the new ship were working well, the Progress -M42 could get away. On 2.02.2000 at 06.10.40UTC the ship undocked from Mir and the return in the atmosphere and the decay over a designated area east of New-Zealand took place that day at 06.57.20UTC.

Orbit corrections Mir-complex:

1st correction: The engines of the Progress-M42 gave the impulses for that orbit correction on 25.01.2000. In this way the altitude of the complex was lifted by a few dozens of kilometers. This was not enough and 2 more corrections were planned. 2nd and 3rd correction: On 7 and 9.02.2000 the engines of Progress M1-1 executed this operation and lifted the complex from approx. 320 KM to a per/apogee of 352/367 KM.

The use of the Progress M1-1 for this purpose (so increasing the altitude) is an indication that the Russians seriously work on plans to continue the operation of Mir in the manned mode for a while or at least put back the decay of the complex. Originally the Progress M1-1 had to lower the altitude of Mir.

Tests of the on board computers and gyrodynes:

Both around 25.01 as on 8.02.2000 the computers (the analogue BUPO for the control of steering rockets and the Main Computer, the digital TsVM-1 for the attitude control by gyrodynes, have been tested. All systems, the gyrodynes included, functioned flawlessly.

The Progress M1-1 delivered to Mir extra oxygen and nitrogen to increase the pressure in the complex, which had decreased dramatically during the last months, and bring this again on a level of approx. 750 MM mercury. Experts will try to open the necessary valves by telecommands. If these attempts would fail the cosmonauts of the 28th M.E. have to do this manually. Then they will have to take special measures to enter the complex.

I was not able to follow the operations in the last 2 months on by base. In that period I made a tourist and space trip to Texas, Alabama and Florida.

Plans for the near future:

So Mir will stay in space for the time being. However we have to be realistic. So to begin with the solid plans:

For a long time the schedule foresaw in the launch of the Soyuz-TM30 with the 28th ME crew consisting of Zalyotin and Kaleri on 31.03.2000. (So this had nothing to do with the founding of the Mircorp). This crew has to stay in Mir for 30 or 45 days for the execution of repairs and modifications aimed at the safe decay of the complex in the atmosphere.

Already for a long period RKK Energiya tried to find investors or customers to be able to continue the exploitation of Mir self-supporting. This endeavour conflicted with the position of Rosaviakosmos (the Russian NASA), as Russia promised to concentrate all means for the Russian contribution in the ISS, the decay of Mir as soon and as safe as possible included. RKK Energiya got permission from the Russian Government and the DUMA to go on with Mir if RKK Energiya the company succeeded in commercial activities from investments by private organisations. The succeeded to get a small amount of money and a lot has been promised. To continue the exploitation of Mir in that way an extensive plan has to be drafted and realised.

Some American millionaires want to invest a lot of money in Mir for the use of the station for several purposes, i.e. as a space hotel for tourists, a platform for the repair of satellites, a kind of node for Internet services and for the execution of experiments by scientific institutes and enterprises.

Gradually the name of Steklov, a Russian actor who should play in film on board Mir, is mentioned as a future visitor of Mir. Fact is that he is still in training for a spaceflight.

A Mr. Manber in England and the director of RKK Energiya, Yuriy Semyonov, signed documents for the founding of a company named Mircorp. At the moment this company has a reference point at a lawyers office in the Dutch city Utrecht, but they are trying to find a location for an office in Amsterdam.

My provisional conclusion: Gradually money is coming in and this makes it possible for RKK Energiya to extend the manned status of Mir, but only with trained cosmonauts and certainly not for tourists. The modules of Mir complex are absolutely unsuitable to be converted into hotel rooms. Mir will never be able to serve as platform for the maintenance of satellites. Due to the fixed orbit and inclination only a very few satellites will be able to come in the neighbourhood of Mir. For limited repair missions only space shuttles are flexible enough.

The representatives who gave statements about Mir Corporation's plans with Mir do not have the necessary background knowledge and need an extensive briefing by their partner RKK Energiya (or even me) to able to give adequate answers on technical and operational questions.

Imager for Magnetopause to Aurora Global Exploration was a MIDEX (mid-sized Explorer mission) developed by NASA-Goddard and the SWRI (Southwest Research Institute) of San Antonio, Texas. The spin-stabilised spacecraft carried a set of neutral atom and ultraviolet imagers, and antennae to study radio wavelength emissions from the magnetosphere plasma. The RPI radio plasma imager has four long wire antennae which will be deployed to a span of half a kilometre.

A launch on April 24 will see Atlantis - fresh off a year-and-a-half of refurbishment and maintenance - dock two days later to an orbiting space station for the first time since it arrived at the Russian Mir space station on STS-86 in September 1997. The orbiter and its external fuel tank/solid rocket booster stack was moved to the launch pad last Saturday and the Spacehab double module was installed into the payload bay earlier this week. A countdown test that includes the seven astronauts will be conducted next Thursday and Friday at the Kennedy Space Center to mirror the events that will take place on launch day.

Soyuz TM-30 docked with Mir's forward (-X) port on April 6 at 0631 GMT. Zalyotin and Kaleri reactivated the uninhabited station. Unloading Progress M1-1 and M1-2, they resupplied the station. The Progress spacecraft were also used to raise the station's orbit to 360 x 378 km x 51.6 deg. The orbital plane of Mir was then around 120 degrees away from that of ISS (making transport between the stations impossible, as desired by NASA).

Lockheed Martin was charged with violating the Arms Export Control Act by assisting China in redesigning their apogee kick motor (EPKM) for the Asiasat-2 communications satellite. This was denied by the Chinese Foreign Ministry, which said that the EPKM was of totally indigenous design.

Atlantis' STS-101 mission remains scheduled for launch at about 4:15 p.m. Eastern time on April 24 with the mission's major goals to accomplish the complete restoration of the electrical power system on the Zarya module and raising the Station's altitude in preparation for Zvezda's arrival in late July.

Sesat (Siberia-Europe Satellite) used an MSS-2500-GSO (Gals/Ekspress) satellite bus built by NPO PM of Krasnoyarsk, with an Alcatel Espace France payload of 18 Ku-band transponders. The satellite had 8 Fakel SPD-100 plasma thrusters for stationkeeping. Eutelsat operated their Hot Bird fleet of European television broadcast satellites since the 1980's, but the venture into broadcasting to Siberia represented a new step for them. Stationed at 36 deg E. Positioned in geosynchronous orbit at 39 deg E in 2000. As of 4 September 2001 located at 35.97 deg E drifting at 0.005 deg E per day. As of 2007 Mar 9 located at 35.92E drifting at 0.004E degrees per day.

Galaxy 4R carried 28 Ku-band and 28 C-band transponders. After insertion in a standard 219 x 32007 km x 7.0 deg geostationary transfer orbit, Galaxy 4R's R-4D apogee engine raised orbit to 35765 x 35792 km x 0.1 deg by April 27 and was over 67 deg W by late April. Final destination was 99 deg W. The Galaxy satellites provide US domestic telecommunications services. 4R replaces the original Galaxy 4H which failed in May 1998, putting pagers out of action across the USA. Stationed at 99 deg W. Positioned in geosynchronous orbit at 73 deg W in 2000. As of 5 September 2001 located at 98.99 deg W drifting at 0.016 deg W per day. As of 2007 Mar 11 located at 76.88W drifting at 0.001E degrees per day.

If all goes as planned, this time next week the International Space Station will house visitors for the first time since the visit by the crew of STS-96 last year. All continues to go smoothly with preparations for the launch of Atlantis to start the STS-101 mission on Monday. Additional Details: here....

This freighter with on board supplies of air, water and fuel for the Mir-station departed from Baykonur to Mir on 25.04.00 at 20.08.02 UTC. The freighter had to dock at Mir on 27.04.00 at about 2130 UTC , so 10 minutes after Mir and Progress M1-2 for us in Western Europe had disappeared behind the eastern horizon.

Progress M1-1: This old freighter separated from Mir on 26.04.00 at 1633 UTC for decay over the Pacific east of New Zealand at 1927 UTC.

Docking Progress M1-2: Approach and docking were executed with the help of the system Kurs. All went flawlessly and smoothly. The freighter docked at the aft docking port (Kvant-2 +X axis) on 27.04.00 at 21.28.48 UTC. During the pass for Western Europe just before the docking (orbit 81124, 2116-2121 UTC) radio traffic revealed that all was going well. Just before LOS for my position the distance to the docking part was 60 Meters and Progress M1-2 was proceeding exactly on course.

During the next pass for my position in orb. 81125, 2252-2258 UTC, the crew reported that they just had opened the hatches to Progress M1-2. The equalisation of the pressures between the station and the freighter lasted long this time. Kaleri said that the cargo bay of the Progress M1-2 was only half full. The air-seal was in good order, but there had been some variations in the air pressure, which in his opinion were caused by the differences in temperature. In 30 minutes the pressure decreased by 4 MM mercury, and then the decrease stopped. At last the pressure inside the station was 687 MM. The crew still had to install the clamps between the Progress M1-2 and the Kvant-1 docking port. These clamps make it impossible for the freighter to wander away.

Meanwhile the control computer Svet had been switched on and Kaleri loaded a number of commands into Svet for the automatic control of a number of systems.

Then the cosmonauts crept into their sleeping-bags. (The bunks for eventual tourists did not yet arrive.). For your scribe a good reason to lay down in the arms of Morpheus.

Orbit corrections: The strong solar maximum causes an increased decay of the orbit altitude of the Mir-space station. Some time ago this decay was about 100 or 150 Meters a day, now this is 4 or 5 times more. The only solution is to lift the orbit of the complex by the use of the engines of the PrM-1 (mostly this is the DPO, the engine for docking and orientation of the freighter is used for that purpose), but once the engines of the Soyuz-TM30 were used (on17.04). Later some more corrections had been given by the DPO of Progress M1-1. So it was difficult to calculate accurate orbit predictions.

Just before the separation of the Progress M1-1 from the complex on 26.04 the DPO of that ship gave another impulse to lift the complex.

More orbit corrections can be expected during the next days, now with the help of the DPO of Progress M1-2.

The acceleration of the decay of the station causes anxiety at TsUP. More even than the possibly still existing small air leaks in the station. This also means that more money has to be reserved in the budget of the "users" for extra fuel.

From the beginning of the 28th Main Expedition the crew has been very busy with air-seal checks in several compartments and modules. This search was intensified on 18 and 19.04.00. The crew worked with special equipment, which had been brought to the station together with the present crew. They spoke about an instrument called Bar and a thermo-hygrometer. The cosmonauts had to disconnect cables in the PKhO (the transition section) to make it possible to close the hatches through which these cables are deployed. The co-ordination with TsUP during these activities was very good and all went well during this risky work.

On 18.04 the crew almost knew where the small leak was and when they were sure about the location they closed or plugged the leak with a cap of stopper. During traffic in the pass on 19.04 in orbit 80988, 0701-0721 UTC TsUP and the crew discussed what kind of plug they should use. In the next pass (orb. 80989, 0834-0841 UTC) Kaleri reported that the "hissing sound ceased".

Thus far it is not fully clear whether this leakage was the only one. Some of the experts at TsUP were not sure for 100%. The air-pressure checks are still going on, but less intensive than before the detection of the leak. The leak was in a valve in the hatch between the PkhO and the &"vacuumed"; module Spektr.

To be honest the crew of this expedition and the experts at TsUP did a great job during the last weeks. In the first place there was the reactivation of the important life support systems, but also the fact that they managed to keep these systems operational and succeeded in the detection of that small leak and the liquidation of that problem.

And let us not forget the flawless automatic approach and docking of the Progress M1-2 which had been equipped by a better system Kurs.

But another fact is less positive: nobody is queuing up in front of the desks where tourists can book a trip to the Mir-space station. And thus far there has not been a single satellite begging Mir for repair or maintenance. In fact a very good thing for the brave crew of Mir will need all their time to keep their iron lung operational.

US civilian geostationary weather satellite in the Geostationary Operational Environmental Satellite series. It was the first GOES launch on the Atlas II launch vehicle (the Atlas I having been phased out). Built by SS/Loral, based on the FS-1300 bus. It was equipped with one solar panel array and a counter-boom with a solar sail. The satellite carried well as an imaging radiometer and an X-ray detector to monitor solar activity. Stationed at 106 deg W. Positioned in geosynchronous orbit at 104 deg W in 2000. As of 5 September 2001 located at 108.58 deg W drifting at 0.018 deg E per day. As of 2007 Mar 11 located at 135.52W drifting at 0.001E degrees per day.

Military Observation. Advanced imaging reconnaissance satellite. Relays digital imagery to earth via geostationary comsats. The last such satellite, Cosmos 2359, reentered in July 1999 after one year in orbit. The Soyuz-U launcher placed it in a 183 x 277 km x 64.8 deg initial orbit; it raised altitude to 240 x 300 km about 24 hr after launch.

DSP-1 Block 14 ballistic missile launch detection satellite. Delivered by the two-stage IUS-22 solid rocket into geostationary orbit. Fullfilled mission of DSP 19 launched in 1999 into the wrong orbit when its IUS stage failed. Still in service as of March 2007. As of 2005 Apr 2 located at 8.05E drifting at 0.166E degrees per day.

On 12.05.2000 the crew of the 28th M.E. to Mir will make an EVA. The beginning of EVA is at 1040UTC (opening of the hatch) and the end at 1605UTC (closing hatch). The cosmonauts will have to carry out a lot of tasks, i.e. the 'sealing' of a little slit in the hull of the base block and the execution of a panorama inspection of the outside of the complex. The crew will use a device called 'Germatizator' and will also dismantle a solar battery from the outside of the Kvant-1 module.

During the last week main subjects during radio contacts were the preparations for the oncoming EVA , such as the airtight checks of the available space suits, and checks of all equipment needed during the EVA, the air seal of connections, the status of valves, oxygen and other tanks and the radio communications system Tranzit.

Almost the whole EVA will be made before Mir comes in range of Western Europe. Possibly the closure of the hatch will just take place during the first pass in orbit 81356, 1605-1613UTC. During the following communication sessions the crew can be monitored during their post-EVA activities.

On 4.05 Zalyotin read out a salute to a recently opened youth forum about subjects like WW-2 and the victory over fascism. Activities during this forum were sports estafettes by representatives of patriotic military clubs. Zalyotin sent the best wishes to the participants.

On 7.05, after the conversations about the next EVA the last communication session was concluded by the TV- or radio broadcast of the inauguration of President Putin. His promise to rule the country in an 'honest and open way' could be heard loud and clear via the 'uplink' channel in the background.

Experiments: In the past 2 weeks now and then the cosmonauts worked on experiments. They spoke about original Russian experiments , for which the 'hardware' is still on board of the station. For the time being it is still unclear who will pay for these experiments and if so, whether this is in the benefit of the shareholders of Mircorp. The crew was executing experiments like the Orangerie (greenhouse), Doza (measurements of the radiation levels on board), Dakon (a liquid convection meter), Optovert, Indikator, etc.

The cosmonauts entered open space via the air-lock of Kvant-2 at 10:44 GMT. The Germatizator experiment, the use of a special glue to seal off cracks on the outside surface of the complex, was executed according to plan. An inspection of a malfunctioning solar panel on Kvant-1showed that the steering cable to the rotor was burnt through due to a short-circuit and was beyond repair. The cosmonauts dismantled an experimental lightweight solar battery from the outer surface of the SO docking compartment. The last activity was the panorama-inspection, making images of the outside of the complex to enable specialist to analyse the effects of ageing of the material. The hatch was closed on what might have been the last spacewalk on Mir at 15:36 GMT.

First Rokot flight from Plesetsk, using a launch pad originally used for Kosmos rockets. The two-stage modified UR-100NUTTKh ICBM, delivered a Briz-KM upper stage to a suborbital trajectory. The first Briz burn was to an approximately 200 x 550 km transfer orbit; the second burn circularized at apogee. It placed two 660 kg dummy satellites in orbits similar to the parking orbit was used for the defunct Iridium program. The Briz-KM stage then made a third burn to lower its perigee to a 178 x 556 km x 86.4 deg disposal orbit.

ISS Logistics flight. Launch delayed three times by weather. Objective of mission STS-101 was repair, resupply and construction tasks aboard the international space station. This was the first launch with new electronic cockpit displays and other upgrades. The solid boosters separated at 10:13 GMT and the main engines cutoff at 10:19 GMT. The external tank, ET-102 then separated, with both orbiter and ET-102 in a 52 x 320 km initial orbit. At 10:54 GMT the OMS engines fired to raise perigee to 159 x 329 km x at 51.6 deg. Atlantis docked with the International Space Station's PMA-2 docking adapter on the Unity node at 04:31 GMT on May 21. At that time the ISS was in a 332 x 341 km orbit.

On May 22 mission specialists Jeff Williams and James carried out external maintenance work on the ISS.

On May 23 at 00:03 GMT the Atlantis crew opened the first hatch to PMA-2 and entered the Station. The crew replaced a set of batteries in Zarya, installed fans and ducting to improve airflow, and delivered supplies and equipment. Three hour-long orbit raising burns on May 24 and 25 by the RCS engines on Atlantis raised the station to a 372 x 380 km x 51.6 deg orbit.

The STS-101 crew left the station on May 26, closing the PMA-2 hatch at 08:08 GMT and undocking at 23:03 GMT. Atlantis performed a 180 degree flyaround of the station and departed the vicinity around 23:44 GMT.

Atlantis closed its payload bay doors around 02:30 GMT on May 29 and fired the OMS engines for deorbit at 05:12 GMT. The vehicle landed on RW15 at Kennedy Space Center at 06:20 GMT. Atlantis was to be turned around for the next ISS shuttle flight, STS-106.

Left in orbit was the renovated International Space Station, equipped with an upgraded electrical system, new fans, filters, fire extinguishers, smoke detectors and communications gear.

Communications satellite. Maiden flight of Atlas IIIA with Russian RD-180 main engine; scrubbed four times. European Telecommunications Satellite Organization (Eutelsat) satellite equipped with 32 Ku-band transponders, and antennae covering Russia and Africa. It will be stationed at 36 deg E. This was the third of the high power Eutelsat W series to be launched (W1 was destroyed in a ground accident). Stationed at 36 deg E. Positioned in geosynchronous orbit at 32 deg E in 2000. As of 4 September 2001 located at 35.98 deg E drifting at 0.003 deg E per day. As of 2007 Mar 9 located at 36.08E drifting at 0.005E degrees per day.

The seven STS-101 astronauts are spending their final full day docked to the International Space Station as they prepare for undocking Friday evening. When Atlantis undocks tomorrow evening, it will leave behind a refurbished orbiting facility, operating at a higher altitude and featuring new electrical and communications components. The station is now primed and ready to receive the next major piece of the station, the Zvezda Service Module, when it is launched from the Baikonur Cosmodrome in Kazakhstan between July 8-14.

These days a huge amount of 'news' about Mir is reaching us. This news comes from different sources. Regretfully the enumerated facts are not always equal and even sometimes full of contradictions.

The transition of the Mir-exploitation from the Russian state to a commercial organisation meant to me that I had to change the way in which I used to publish information gathered by monitoring of radio communications. It would be incorrect to use that to put spokes in Mircorp's wheels.

Own 'observations' force me to take a lot of that what is published with a grain –and even sometimes 'ounces'- of salt. As an example can serve the information about the air leaks. The search for leaks and the air pressure checks still go on, but some days ago publications suggested that the station was fully airtight. On 25.05 the deputy Head of TsUP, V D Blagov, told the press that the certainty about this cannot be given earlier than next week when all airtight checks in the Kvant-module and the Base Block will be concluded. (Of all persons who give information about the state of the Mir-complex Blagov is the only one on which I rely for 100%.)

Another example of inconsistent publicity was the information that the crew would return to earth in the midst of June. So somehow the date 16.06 emerged. During a radio contact on 25.05 TsUP asked Zalyotin if the crew would have objections against the training for the return operations on 5.06. Zalyotin said that there were no objections, but that he would like to hear when the return was scheduled. TsUP uttered the possibility that this would be 16.06, but that this question was still under consideration. A spokesman at TsUP declared, also on 25.05, that there had not yet been a decision about the date of return and that a prolongation of the flight was still an option.

Stakhanovtsy: In the decade between 1930 and 1940 workers in the S.U. who managed to produce more than the plan demanded, got the title of honour 'Stakhanovets'. A tovarishch with that name was the first 'hero' in that respect. The present crew on board Mir is working so hard that it seems as if they try to achieve the title 'Stakhanovtsy'. The present dense radio traffic makes it clear that the crew is working extremely hard. Among the activities to prepare the complex for the oncoming autonomous flight they have to execute a lot of experiments, but they also continue repairs and the replacement of equipment and parts , like filters, ventilators, cables, pumps, valves, etc. A lot of time has to be invested in those activities and often the time-tables and schedules (the so-called cyclograms) cannot be used. Not all repairs are feasible.

The most attention has to be given to the life-support systems. The air pressure checks go on and with the instrument Bar the cosmonauts use temperature and humidity sensors to detect tiny air streams in the Module Kvant and the Base Block. After the EVA on 12.05 the airlock of Module-D (the ShSO.) got extra checks. With Bar they searched near the portholes and an air valve, the KSD. The crew has also worked on the pipes for the heating system KOB. Using the Germatizator glue and tape (possibly metallic) they sealed off leaks and cracks in those pipes.

On 20.5.2000 during the pass in orbit 81479, 1243-1247UTC, Zalyotin reported that the air-pressure was 664 MM Mercury and also that they just had burnt 3 cartridges. (These are lithium perchloride cartridges to produce extra oxygen. Possibly the Elektrons are not fully utilized due to the failure of the crucial solar battery on Kvant-1).

Experiments: The crew spoke about the experiments Optovert, Linza, Pelena, Prochnostj, Indikator and the medical ones in the MK-series, and they carried out experiments in the greenhouse Svet or Orangery. On 24, 25 and 26.05 the crew transmitted TV-images or video-films to TsUP. To adjust or aim the cameras, among which the LIV, Zalyotin had to go into the Module-Kristall. Files containing results of experiments are transmitted to earth via the telemetry system with the modem or interface BITS.

Communications: These are very intensive, especially because of the fact that all passes now take place within the normal working hours. Due to the limited communications infrastructure the Russians have to use every available communications window (Oberpfaffenhofn, White Sands, Dryden and Wallops do not play a role during this expedition). It is quite normal that I daily produce 4 or 5 pages A-4 with written translations of radio communications.

And last but not least: Information of TsUP on 26.05.2000 at 0900UTC. Provisional date of return of Zalyotin and Kaleri with the Soyuz-TM30 on 9.06.2000 with alternative: 14.06.2000. But I beg you all: don't blame me if this will not come true.

Having departed a rejuvenated International Space Station last night, Atlantis' crew will now spend a day checking the shuttle's equipment and stowing away gear in preparation for the trip home, aiming for a 1:20 a.m. CDT landing on Monday at the Kennedy Space Center in Florida. Additional Details: here....

Communications satellite. First successful Proton/Briz-M launch. The Proton placed the Briz-M/Gorizont payload stack into a suborbital trajectory. The stage then performed four maneuvers to put the satellite into geosynchronous orbit:

• Burn 1 placed the stack into a 200 km, 51.6 deg parking orbit probably inclined at around 51.6
• Burn 2 raised apogee to 6000 km and changed inclination slightly
• Burn 3, at second perigee, four hours after launch put the stack in a 369 x 34,988 km x 48.8 deg transfer orbit. The Briz-M then jettisoned its empty toroidal supplementary fuel tank.
• Burn 4, ten hours after launch, placed Gorizont No. 45L in near-geostationary orbit.

Military Technology satellite. Launch delayed from May 20 and June 6. Fifth STEP (Space Test Experiments Program) satellite. The satellite's main section was the STRV-2 experiment module, sponsored by the Ballistic Missile Defense Organization and the UK Ministry of Defense. This was to take infrared images of UK military aircraft at perigee, and then downlink data via laser. STRV-2 also carried vibration isolation and debris impact sensors. A secondary payload was the S97-1 CEASE (Compact Environmental Anomaly Sensor). This was an AFRL prototype sensor package to provide warning of spacecraft charging and radiation events. Air dropped in Point Arguello WADZ.

Launch delayed from June 23. Geosynchronous communications satellite. Stationed at 11 deg W. Positioned in geosynchronous orbit at 11 deg W in 2000. As of 5 September 2001 located at 10.99 deg W drifting at 0.005 deg W per day. As of 2007 Mar 11 located at 11.00W drifting at 0.005E degrees per day.

Second Fengyun-2 weather satellite, replacing the first FY-2 (retired in April after a three year service life). The spin-stabilised FY-2 fired its solid apogee motor early on Jun 26. By July 3, it was in a 35,791 x 35,804 km x 1.1 deg orbit drifting over the Pacific. Stationed at 104 deg E. Positioned in geosynchronous orbit at 110 deg E in 2000. As of 5 September 2001 located at 104.56 deg E drifting at 0.030 deg W per day. As of 2007 Mar 11 located at 34.70W drifting at 0.629W degrees per day.

Tsinghua University of Beijing satellite equipped with an imager, communications payload, and momentum wheels for 3-axis stabilisation. The 50 kg, 0.69 x 0.36 x 0.36m box-shaped satellite used a standard Surrey SSTL microsat bus.Tsinghua-1 was the first demonstrator for the planned Disaster Monitoring Constellation and carried a multi-spectral Earth imaging camera providing 39-metre nadir ground resolution in 3 spectral bands. The satellite also carried out research in low Earth orbit using digital store-and-forward communications, a digital signal processing (DSP) experiment, a Surrey-built GPS space receiver and a new 3-axis microsat attitude control experiment. Tsinghua-1 used the SGR-10, with 12 channels and equipped with two receive antennas, to investigate the use of GPS signals in microsat on-board attitude and orbit determination. In October 2000 Surrey Satellite Technology Ltd (SSTL) released a picture of Tsinghua-1 taken in orbit by the SNAP-1 6.5 kg nanosatellite.

The SNAP-1 Surrey Nanosatellite Applications Platform was a 6 kg satellite with imager and propulsion. It was to test rendezvous techniques by formation flying with the Tsinghua satellite placed in orbit on the same launch. In October 2000 Surrey Satellite Technology Ltd (SSTL) released a picture of Tsinghua-1 taken in orbit by the SNAP-1 6.5 kg nanosatellite.

After a week of comprehensive reviews by program managers on both sides of the Atlantic Ocean, the next component of the International Space Station (ISS) is poised for launch to provide the early living quarters for the first permanent occupants of the orbital outpost.

Launch delayed from June 29. First Advanced Tracking and Data Relay Satellite, using a Hughes HS 601 satellite bus. It included an S-band phased array antenna and two Ku/Ka band reflectors 4.6 meters in diameter. The satellite was launched into a a 167 x 577 km x 28.3 deg parking orbit at 13:05 GMT. The Centaur upper stage made a second burn at 13:21 GMT, releasing the satellite into a subsynchronous transfer orbit of 237 x 27,666 km x 27.0 deg. The satellite's own Primex/Marquardt R4D liquid apogee engine would be used to maneuver the satellite into its final geosynchronous orbit. Stationed at 151 deg W. Positioned in geosynchronous orbit at 150 deg W in 2000. As of 5 September 2001 located at 149.99 deg W drifting at 0.014 deg E per day. As of 2007 Mar 11 located at 145.38E drifting at 3.007W degrees per day.

Digital Audio Radio Satellite, used for transmission of S-band radio broadcasts direct to receivers in cars in the United States. Sirius 1 was inserted into an initial 6,166 x 47110 km x 63.4 deg transfer orbit by the Proton-K's Blok DM3 upper stage. The satellite's R4D liquid apogee engine made several burns to raise the orbit to 24,388 x 47,097 km x 63.3 deg by July 8. This elliptical, inclined 24 hour orbit had a 24 hour period, designed to keep the satellite between longitude 60W and 140W, with apogee over the northern hemisphere. Stationed at 66 deg W. Positioned in geosynchronous orbit at 66 deg W in 2000. As of 6 September 2001 located at 65.59 deg W drifting at 0.015 deg E per day. As of 2007 Mar 9 located at 65.37W drifting at 0.004E degrees per day.

Second flight using RD-0210 Phase 2 engines. Geizer military communications satellite. The Blok DM upper stage inserted the Geizer into geosynchronous orbit at 06:20 GMT on July 5. Stationed at 80 deg E. Positioned in geosynchronous orbit at 80 deg E in 2000. As of 6 September 2001 located at 79.81 deg E drifting at 0.014 deg E per day. As of 2007 Mar 10 located at 79.73E drifting at 0.022W degrees per day.

A C-band transponder on the mock warhead provided location information; its data was compared against its GPS receiver to determine its accuracy. The only decoy used was the large balloon from previous tests. It did not inflate properly, causing MDA officials to use a different decoy in the future.

ABM test failure. Second end-to-end system test (intercept attempt) using NMD prototype elements and range assets to approximate the objective system. The IFICS served as the communication link between the BMC3 and EKV. The EKV did not separate from the surrogate booster due to an apparent failure in the 1553 data bus in the booster.

Years behind schedule, the Zvezda living module of the International Space Station, built and financed by Russia, finally reached orbit. Zvezda's initial orbit was 179 x 332 km x 51.6 deg. On July 14 the orbit was raised to 288 x 357 km. ISS was then in a 365 x 372 km orbit. After matching orbits with the ISS, Zvezda then became the passive docking target for the Russian-built, US-financed Zarya module already attached to the station. The Zarya/Unity stack docked with the Zvezda module at 00:45 GMT on July 26, forming the basic core of the International Space Station. A flood of NASA missions would follow to bring the station into operation.

The Zvezda service module is in excellent shape a day after its launch aboard a Proton rocket from the Baikonur Cosmodrome. Zvezda was launched at 12:56 a.m. EDT Wednesday and was on its own 10 minutes later after the Proton's third stage separated and fell away from the module. Additional Details: here....

The first two European Space Agency Cluster II satellites, Samba (FM7) and Salsa (FM6) were launched into an initial 200 km / 64.8 deg circular orbit. The Fregat upper stage then burned once before ejecting the satellites into a 250 x 18072 km x 64.7 deg transfer orbit. Both satellites then used their Astrium (former MBB) S400 liquid engines in a series of four additional burns before reaching their final 16869 x 121098 km x 90.6 deg orbits. Each magnetosphere research satellite deployed four 50-meter wire antennas.

Mightysat 2.1, also known as Sindri, used a Spectrum Astro SA-200B satellite bus. The spacecraft carried a hyperspectral imager for earth imaging and spectroscopy, as well as satellite technology experiments such as advanced solar arrays. An Aerospace Corp./DARPA picosatellite experiment, consisting of two small boxes connected by a deployable tether, was deployed later. Similar picosats were deployed on the previous Minotaur launch in January 2000.

With its days flying alone in orbit coming to an end, the Zvezda service module nears completion of systems checkouts in preparation for docking to the International Space Station. The linkup remains scheduled for 8:53 p.m. Eastern Time next Tuesday, July 25, as the two spacecraft fly high above the Russian Federation within the coverage area of ground communication stations. Additional Details: here....

The International Space Station's newest module, Zvezda, has completed all of its planned maneuvers and now awaits the arrival of its permanent home in space as the Zarya control module takes over the remaining rendezvous tasks. The updated docking time is 8:44 p.m. Eastern Tuesday. Additional Details: here....

The newest component for the ever-growing International Space Station, the Russian Zvezda Service Module, successfully linked up with the fledgling complex this evening as the two craft flew high over the northeast portion of Kazakhstan marking the arrival of the first living quarters for the permanent human habitation of the new outpost. Additional Details: here....

Russia invited China to participate in financing a new group of Glonass satellites. An operational system would require 24 satellites to be in operation. However by mid-2000 there were only 14 satellites available, and only nine fully operating. The system would require 1.5 billion rubles a year to operate and replenish the satellite constellaton.

The group was selected to provide pilot, engineer, and scientist astronauts for space shuttle flights.. Qualifications: Pilots: Bachelor's degree in engineering, biological science, physical science or mathematics. Advanced degree desirable. At least 1,000 flight-hours of pilot-in-command time. Flight test experience desirable. Excellent health. Vision minimum 20/50 uncorrected, correctable to 20/20 vision; maximum sitting blood pressure 140/90. Height between 163 and 193 cm.

Mission Specialists: Bachelor's degree in engineering, biological science, physical science or mathematics and minimum three years of related experience or an advanced degree. Vision minimum 20/150 uncorrected, correctable to 20/20. Maximum sitting blood pressure of 140/90. Height between 150 and 193 cm.. Seven pilots and ten mission specialists; 14 men and 3 women.

Panamsat geosynchronous communications satellite to replace PAS 5 at 58 deg W. Stationed at 58 deg W. Positioned in geosynchronous orbit at 58 deg W in 2000. As of 30 August 2001 located at 58.03 deg W drifting at 0.012 deg W per day. As of 2007 Mar 9 located at 58.06W drifting at 0.013W degrees per day.

Progress M1-3 automatically docked with the International Space Station on August 8 at 20:13 GMT at the rear Zvezda port. The supply ship began refuelling of the station a few days later. It remained attached for offloading of its dry cargo by the STS-106 crew. It later separated from Zvezda's rear port at 0405 GMT November 1 and was deorbited over the Pacific at 0705 GMT.

The stage is set for another docking to the International Space Station (ISS) Tuesday - this time by a Russian Progress supply vehicle that launched Sunday from the Baikonur Cosmodrome in Kazakhstan. The Progress is delivering clothing, computers, personal hygiene items, office supplies, food and fuel for the first permanent residents of the Station, the Expedition One crew, which is scheduled to arrive on board in early November. Additional Details: here....

Rumba and Tango were the second pair of Cluster II magnetospheric research satellites of the European Space Agency. A series of five burns of the Fregat stage took them from an initial 190 km / 64.8 degree parking orbit to their final 17,200 x 120,600 km orbits inclined 90 degrees to the equator. They then separated from the Fregat and took up operations.

Brasilsat B4 was a C-band geosynchronous communications satellite, replacing the 15-year-old Brasilsat A2 for the Brazilian communications company Embratel. Positioned in geosynchronous orbit at 75 deg W in 2000. As of 2 September 2001 located at 92.03 deg W drifting at 0.011 deg W per day. As of 2007 Mar 9 located at 70.08W drifting at 0.020W degrees per day.

Geosynchronous communications satellite of the Egyptian company Nilesat SA. The satellite joined Nilesat 101 in providing Ku-band broadcast services. Stationed at 7 deg W. Positioned in geosynchronous orbit at 7 deg W in 2000. As of 2 September 2001 located at 6.98 deg W drifting at 0.002 deg W per day. As of 2007 Mar 9 located at 6.97W drifting at 0.004W degrees per day.

The National Reconnaissance Office satellite was reported to be an Onyx (formerly Lacrosse) radar imaging spacecraft built by Lockheed Martin. The Titan second stage reached a 572 x 675 km x 68.0 deg orbit and separated from the payload. Amateur observers reported the payload has made two small maneuvers and by Aug 23 was in a 681 x 695 km x 68.1 deg orbit.

Vehicle Demonstration. Return to flight following earlier failure. The third Boeing Delta III launch was financed by the company and carried a dummy payload in order to bolster customer confidence in the new launch vehicle. The second stage ignited at an altitude of 158 km and the RL-10 shut off as planned in a 157 x 1363 km x 29.5 deg parking orbit. The engine fired again until fuel depletion, to place the vehicle in a geostationary transfer orbit of 190 x 20,655 km x 27.6 deg. This was much lower than that planned (23,400 km plus or minus 3,000 km) due to the fuel temperature and atmospheric conditions on the day of launch. The DM-F3 dummy payload was a mass model of the Orion 3 HS-601 satellite launched on the second Delta 3. The 4348 kg model was a 2.0m diameter, 1.7m high cylinder with two circular end plates, painted with black and white patterns. It was to be used by US Air Force researchers as a calibration target.

Raduga-1 military communications satellite initially named Cosmos 2372 by the RVSN press service. Stationed at 50 deg E. As of 5 September 2001 located at 49.25 deg E drifting at 0.048 deg W per day. As of 2007 Mar 10 located at 45.70E drifting at 0.012W degrees per day.

The ZY-2 (Ziyuan-2 ('Resource-2'), while disguised as a civilian earth monitoring system, was actually code-named Jianbing-3 and was China's first high-resolution military imaging satellite. The cover story of the official Xinhua news agency was that the civilian remote sensing system would be used primarily in territorial surveying, city planning, crop yield assessment, disaster monitoring and space science experimentation. However the satellite was placed at a much lower altitude than the ZY-1 satellite and US intelligence sources indicated that it was a photo-reconnaissance satellite for exclusively military purposes, such as targeting missiles at US and Taiwanese forces. The new satellite was believed to employ digital-imaging technology and to have a resolution of 2 m or less. The satellite was designed and built by the Chinese Academy of Space Technology and was developed indigenously. It was said to be more advanced than earlier sensing satellites and was expected to have an orbital life of two years. The camera provided more than three times the resolution of the ZY-1 earth resources satellite. The Zi Yuan 2 satellite may have used the CBERS Sino-Brazilian bus of the earlier ZY-1. However it was also said to be of new design and demonstrated the capability to maneuver in orbit, adjusting its orbit after launch. In October 2000 Chinese scientists denied that the ZY-2 satellite had a military mission. It was said to be a remote-sensing satellite equipped with CCD cameras and an infrared multispectral scanner that could only identify objects on the ground with a resolution of several dozen meters to 1 km.

Sirius Radio's Sirius 2 was launched into a 144 x 168 km x 64.8 deg parking orbit. The Blok DM3 stage then made two burns to deliver Sirius 2 to an elliptical 6192 x 47057 km x 63.4 deg orbit. The was to provide digital radio broadcasts to mobile users in North America. Stationed at 64 deg W. As of 31 August 2001 located at 64.56 deg W drifting at 0.003 deg W per day. As of 2007 Mar 10 located at 67.77W drifting at 0.049E degrees per day.

European Telecommunications Satellite Organization's Eutelsat W1 was launched into a geostationary transfer orbit, targetted for a final 10 deg E orbital position. The box-shaped 2.5 x 5.0 m satellite has two rectangular solar panel arrays spanning 31.7m and two dishes, a European beam and a steerable beam. The payload includes 28 Ku-band transponders. Stationed at 10 deg E. Positioned in geosynchronous orbit at 1 deg E in 2000. As of 1 September 2001 located at 9.92 deg E drifting at 0.005 deg E per day. As of 2007 Mar 8 located at 10.05E drifting at 0.006W degrees per day.

Atlantis was launched from Kennedy Space Center's Launch Complex 39B. Solid rocket boosters RSRM-75 and external tank ET-103 were used to loft the orbiter into space. The inital orbit of 72 x 328 km x 51.6 deg was circularised by the Shuttle's OMS engines at apogee.

Atlantis docked with the PMA-2 adapter on the International Space Station at 05:51 GMT on September 10. The orbiter's small RCS engines were used to gently reboost the station's orbit several times.

Astronauts Lu and Malenchenko made a spacewalk on September 11 beginning at 04:47 GMT. They rode the RMS arm up to Zvezda and began installing cables, reaching a distance of 30 meters from the airlock when installing Zvezda's magnetometer. Total EVA duration was 6 hours 21 minutes.

During their 12-day flight, the astronauts spent a week docked to the International Space Station during which they worked as movers, cleaners, plumbers, electricians and cable installers. In all, they spent 7 days, 21 hours and 54 minutes docked to the International Space Station, outfitting the new Zvezda module for the arrival of the Expedition One crew later this fall.

The Shuttle undocked from ISS at 03:44 GMT on September 18 and made two circuits of the station each lasting half an orbit, before separating finally at 05:34 GMT. The payload bay doors were closed at 04:14 GMT on September 20 and at 06:50 GMT the OMS engines ignited for a three minute burn lowering the orbit from 374 x 386 km x 51.6 deg to 22 x 380 km x 51.6 deg. After entry interface at 07:25 GMT, the orbiter glided to a landing on runway 15 at Kennedy Space Center with main gear touchdown at 07:56:48 GMT for a mission duration of 283 hr 11min.

STS-106 Mission Commander Terry Wilcutt along with his crew, Pilot Scott Altman and Mission Specialists Ed Lu, Rick Mastracchio, Dan Burbank, Yuri Malenchenko and Boris Morukov, were awakened at 5:46 p.m. CDT today. The wake up song from Mission Control was " I Say a Little Prayer" which was played for Wilcutt. All seven astronauts are now busy with final preparations for the docking with the International Space Station set for early tomorrow morning. Atlantis is planned to make the third docking with the station at 12:52 a.m. Additional Details: here....

Commander Terry Wilcutt steered Space Shuttle Atlantis to a smooth link-up with the International Space Station at 12:51 a.m. CDT Sunday, setting the stage for six days of outfitting to make the orbiting outpost ready for its first residents in early November. Additional Details: here....

"All Star" by the band Smash Mouth. The song was played for the two space walkers at the request of the EVA training and flight control teams to celebrate what will be the sixth space walk in support of station assembly and the 50th space walk in Space Shuttle history.

Direct Broadcasting satellite. Launch postponed from July 25. Astra 2B was an Astrium/Toulouse Eurostar 2000+ television broadcast satellite owned by the Luxembourg-based Societe Europeene de Satellites. The satellite was to be stationed at 28.2E to replace the German DFS Kopernikus. It carried 28 Ku-band transponders. By September 19 Astra 2B was in a 31,153 x 35,762 km x 0.3 deg orbit, approaching geosynchronous altitude. Stationed at 28 deg E. Positioned in geosynchronous orbit at 28 deg E in 2000. As of 20 August 2001 located at 28.50 deg E drifting at 0.011 deg E per day. As of 2007 Mar 10 located at 28.15E drifting at 0.017W degrees per day.

Direct Broadcasting satellite. GE Americom satellite to provide cable TV distribution coverage to the USA. Equipped with 24 C-band transponders. Its dry mass was 912 kg and it carried 1023 kg of fuel at launch. The satellite is an A2100A model built by Lockheed Martin/Lockheed, the first lightweight A2100 with a mass about half that of earlier A2100 satellites. By September 19 GE 7 was in a 35,832 x 35,869 km x 0.1 deg orbit drifting over 146 deg W. Stationed at 137 deg W. Positioned in geosynchronous orbit at 137 deg W in 2000. As of 4 September 2001 located at 136.92 deg W drifting at 0.003 deg E per day. As of 2007 Mar 9 located at 137.03W drifting at 0.000E degrees per day.

Shape and contents of this Mir-message deviate from those published before 17.06.2000. Those Mir-reports largely depended on the radio-conversations between the crews and Flight Control (TsUP) in Moscow.

The Mir complex continues to orbit earth as if nothing has happened. The fact that Mir is unmanned enabled me to visit some cradles of Mir in Moscow. As of 10.09 until 16.09 I lived in Zvyozdnyy Gorodok, so near TsPK, the Training Centre of Cosmonauts. Physically it is impossible to visit all institutes, KB-s (construction bureaus), factories, facilities, stations etc. , which directly or indirectly were or are related to Mir: in fact there are hundreds of them.

During our stay, Bert Vis was my traveling-companion. We enjoyed the opportunities offered to us to visit some of the most important institutes and we did this in a way strongly differing from the usual excursions with groups. Everywhere we were invited as expert guests and the treatment we experienced was in accordance to that.

About Mir:

One of our visits was at TsUP near Moscow. TsUP is still involved in a number of satellite operations of which the two most important are the control of the Mir complex and – though for a part together with the American TsUP in Houston -- of the ISS. The sections for Mir and the ISS at TsUP operate fully separated: for Mir the old room (well-known from the media) is in use and for ISS the modified room originally built for Buran is in use.

During our visit the Mir station came in reach of the tracking facility in Shcholkovo and from that moment on just a few of the operational positions on the ground floor, were occupied by specialists. From the telemetry on their screens they analysed the for them relevant data. Like in the past the orbit and position of the complex could be seen on a world map and we could read elements like AOS and LOS and which tracking facilities were active. From conversations with insiders we could conclude that the tracking stations are still staffed by military personnel and that in this way the Russian state supports the exploration of Mir.

We thoroughly discussed the future of the station, with specialists as well as with cosmonauts and in this way we got on the spot information about dramatic changes in the plans thus far.

Originally 2 Main Expeditions (ME) were scheduled for the beginning of 2001: ME29 with the crew Sharipov and Vinogradov to be followed by the relief crew of ME30, consisting of the cosmonauts Musabayev and Baturin and the tourist – so definitely not a cosmonaut- the American citizen Denis Tito. The knowledge of the Russian language of Tito is very poor and to convert him into a cosmonaut within the period of a few months is a 'mission impossible'. We met the group of young cosmonauts and this made that clear for us. Meanwhile Tito paid 22 million US-dollars of a promised 50 million. This is not enough for the execution of 2 expeditions to Mir. Tito returned to TsPK on the 14th or 15th of September, but regretfully we did not meet him.

Now the decision has been made to appoint the original ME30 crew for the first and only ME to Mir, so in that case this will be ME29, consisting of Musabayev, Baturin and Tito.

The launch date of their ship, Soyuz-TM31, has been set for 18.01.2001 and the duration of the flight will be 14 or 10 days.

The logic of this decision is that Musabayev and Baturin speak English very well and so they can at least chat with their passenger.

In the week after our arrival we got this information from some well informed sources and on the day of our departure we met Musabayev who confirmed this.

About ISS:

The number of operators in the ISS-control room was also poor. Some TV-camera crews were walking about. The orbit and position of ISS could be seen on a monitor and the details of the communication windows were visible (AOS, LOS, etc.) Malenchenko and Ed Lu were doing their EVA and pictures were showed on a big screen. TsUP Moscow passively experienced the EVA-operation, for Houston was in charge and the communications took place by the use of TDRS-. We hope that this passiveness of TsUP-M now and then will be interchanged by active participation in the ISS flight control, but we fear the worst.

Our excursions etc.:

During the rest of the week we visited facilities like OKB Mashinostroyeniye, the former OKB-52 of the famous, but regretfully overshadowed by the glories and fame of Korolyov, Vladimir Nikolayevich Chelomei. In fact Chelomei was the real founder of the Russian space stations, Almaz, Salyuts and without him Mir's history would be different, not to speak about the actual Zarya en Zvezda. At Mashinostroyeniye we saw two real Almaz stations, the TKS , transport ship for the Almaz and a real Polyot., the first satellite that was able to manoeuvre in space. Our visit inside one of those Almaz was a revelation: what a room and what a perfect ergonomy. But regretfully we had to keep our cameras in our covers. A photographer of the OKB had got orders to make pictures: he shot 12 pictures of which 'security' accepted only 4, 2 of which on the premises outside –monuments- and 2 inside of us covering the most part of the TKS and of Almaz we saw a little piece of the hull while we fully shaded off the Polyot in the background.

The attitude towards our own photography of the State Research and Production Space Center Khrunichev was much better: we were not allowed to make photos of all objects, but were free to shoot pictures of the Proton under construction. We were standing on historical soil for until 1926 (the treaty of Versailles prohibited this on German territory) German aircraft were constructed and tested on the aerodrome here. So that what destroyed Rotterdam and Coventry in 1940 was prepared in Russia by the German specialists of General von Seeckt. But in fact a few years later the Soviet Union herself got in that way a biscuit of own paste.

We had personal contacts with a lot of old and young cosmonauts. The visit to the TsPK itself was very good: we saw Shepard and Gidzenko training in repairing something at the outer surface of Zarya in the underwater tank and, in the training hall for the Soyuz, Sergey Krikalyov was trying to dock his ship with ISS, while the ISS-2 expedition (Bowersox, Dezhurov and Tyulin) did the same in a second training module. And when you with a lot of other thinks can sit behind a real TORU, you have reason to be really satisfied.

A highlight during my stay was a one and a half hour lasting conversation with the famous professor B. Ye. Chertok, a constructor from far before WW2, who participated in all developments of Sputniks, Vostoks, Voskhods, Salyuts, Molniyas etc. A lot of the subjects discussed were very interesting for me: communication systems and procedures, electronic docking systems, for instance Kontakt, Igla, Kurs and even the brand new Kurs-MM. Chertok a strong man of 88 years, sustained the siege of my questions very well. As soon as I can find some time I will draft a summing up.

And finally:

On 15.09 General P.I. Klimuk, head of TsPK, just returned from America, found 10 minutes in the late afternoon to receive me and Bert. We expressed our gratitude that we had been permitted to stay in Zvyozdnyy and he told us that he appreciated our work en our positive attitude towards Russian spaceflight.

As of 2007 Mar 11 located at 110.07E drifting at 0.007W degrees per day.

First orbital launch from Kwajalein. Second High Energy Transient Explorer; built by MIT using leftover parts from the first HETE. This failed to operate because of a Pegasus adapter failure during launch in November 1996. MIT operates the satellite, while the program is managed by NASA GSFC as an Explorer mission of opportunity. HETE's main instrument is FREGATE, the French Gamma Telescope, a hard X-ray spectrometer operating in the 6 to 400 keV energy range. This gamma ray burst detector, together with a Wide Field X-ray Monitor hard X-ray coded mask telescope, is used to trigger searches with the two Soft X-ray Imagers which have 33-arcsecond spatial resolution. This will let astronomers get precise locations for gamma-ray bursts, allowing detailed follow-up with optical instruments. The satellite is in a 595 x 636 km x 2.0 deg equatorial orbit, and sends data to a network of small ground terminals spaced around the equator. Air dropped in Kwajalein DZ.

ISS Logistics flight. 100th shuttle flight. Launch delayed from October 6. STS-92 brought the Z-1 Truss (mounted on a Spacelab pallet), Control Moment Gyros, Pressurised Mating Adapter-3 (PMA-3) and two DDCU (Heat pipes) to the International Space Station.

The RSRM-76 solid rocket boosters separated at 23:19 GMT and main engine cut-off (MECO) came at 23:25 GMT. External tank ET-104 separated into a 74 x 323 km x 51.6 deg orbit. At apogee at 00:01 GMT on Oct 12, Discovery's OMS engines fired to raise perigee to a 158 x 322 km x 51.6 deg orbit; ET-104 re-entered over the Pacific around 00:30 GMT. At Oct 12 on 03:01 GMT the NC1 burn raised the orbit to 180 x 349 km; NC3 on Oct 12 to 311 x 375 km; and the TI burn at 14:09 GMT on Oct 13 to 375 x 381 km x 51.6 deg. Discovery's rendezvous with the International Space Station came at 15:39 GMT on Oct 13, with docking at 17:45 GMT. The spaceship docked with PMA-2, the docking port on the +Y port of the Space Station's Unity module. Hatch was open to PMA-2 at 20:30 GMT the same day.

STS-92 Cargo Manifest

• Bay 1-2: Orbiter Docking System + 3 EMU spacesuits
• Bay 5 Port: Adapter Beam with DDCU-HP control unit
• Bay 5 Starboard: Adapter Beam with DDCU-HP control unit
• Bay 7-8: Spacelab Pallet MD003 with PMA-3
• Bay 10-12: ISS Z1 first segment of the space station truss
• Bay 13 Adapter Beam with IMAX Cargo Bay Camera
• Sill: Canadarm RMS 301

Total payload bay cargo: ca. 14,800 kg

The Z1 first segment of the space station truss was built by Boeing/Canoga Park and was 3.5 x 4.5 meters in size. It was attached to the +Z port on Unity. Z1 carried the control moment gyros, the S-band antenna, and the Ku-band antenna.

PMA-3, built by Boeing/Huntington Beach, was docked to the -Z port opposite Z1. PMA-3 was installed on a Spacelab pallet for launch.

On October 14 at 16:15 GMT the Z1 segment was unberthed from the payload bay and at around 18:20 GMT it was docked to the zenith port on the Unity module.

On October 15 at 14:20 GMT the ODS airlock was depressurised, beginning a spacewalk by Bill McArthur and Leroy Chiao. Official NASA EVA duration (battery power to repress) was 6 hours 28 minutes.

The second spacewalk was on October 16, with Jeff Wisoff and Mike Lopez-Alegria. The suits went to battery power at 14:15 GMT and Wisoff left the airlock at 14:21 GMT. Repressurisation began at 21:22 GMT for a duration of 7 hours 07minutes.

Leroy Chiao and Bill McArthur began the third STS-92 EVA at 15:30 GMT on October 17, completing their work at 22:18 GMT for a total time of 6 hours 48 minutes.

After the spacewalk, Discovery completed the second of the three station reboosts scheduled for STS-92. They fired reaction control system jets in a series of pulses of 1.4 seconds each, over a 30-minute period, gently raising the station's orbit by about 3.1 km.

The last of four successful spacewalks began on 18 October at 16:00 GMT and ended at 22:56 GMT, lasting 6 hours and 56 minutes. Jeff Wisoff and Mike Lopez-Alegria each jetted slowly through space above Discovery's cargo bay.

After the space walk, Discovery completed the third and final reboost of the space station.

On 19 October the astronauts worked within the ISS. They completed connections for the newly installed Z1 external framework structure and transferred equipment and supplies for the Expedition One first resident crew of the Station. The crew also tested the four 290-kg gyroscopes in the truss, called Control Moment Gyros, which will be used to orient the ISS as it orbits the Earth. They will ultimately assume attitude control of the ISS following the arrival of the U.S. Laboratory Destiny. The tests and the transfer of supplies into the Russian Zarya Module took longer than expected. As a result, the crew's final departure from the Station's Unity module was delayed. Melroy and Wisoff took samples from surfaces in Zarya to study the module's environment. They then unclogged the solid waste disposal system in the Shuttle's toilet, which was restored to full operation after a brief interruption in service.

Discovery undocked from the ISS at 16:08 GMT on 20 October. The final separation burn was executed about 45 minutes after undocking. The crew had added 9 tonnes to the station's mass, bringing it to about 72 tonnes. The return to earth, planned for 22 October, was delayed repeatedly due to high winds at the Kennedy landing site. The landing was finally made at Edwards Air Force Base, California, on October 24, at 22:00 GMT.

The seven crew members aboard the Space Shuttle Discovery spent their first full day in orbit today checking equipment in preparation for the major events to come: docking with the International Space Station on Friday and, in following days, attaching an exterior framework and additional Shuttle docking port to the orbiting outpost. Additional Details: here....

Three navigation satellites for the GLONASS system were launched by a single Proton-K/Blok DM-2 upper stage into an initial 160 km x 64.8 deg parking orbit. The Blok DM-2 made two burns to maneuver into a 19120 x 19120 km x 64.8 deg orbit and deployed the three satellites about four hours after launch.

During the International Astronautical Federation (IAF) annual congress in Rio de Janeiro, China unveiled deatils of its new CZ-5 heavy launch vehicle family. Powered by kerosene/LOX/LH2 engines and four strap-on boosters, the new 800-ton, 50-55-meter high launcher would be capable of lifting 23 tonnes into LEO and 11 tonnes into geostationary transfer orbit. The CZ-2E(A), equipped with new avionics from the man-rated CZ-2F, was to be tested by 2003. The CZ-1D small launcher was slated to make its first flight in 2001, while yet another small launcher, a 4 stage solid rocket, was under design.

Wakata aboard the shuttle used the RMS arm to unberth the PMA-3 docking unit from the SLP pallet at 16:14 GMT, and docked it to Unity at 17:40 GMT. Wisoff and Lopez-Alegria first unbolted PMA-3 from the SLP and then guided Wakata through the delicate alignment process as PMA-3 was removed from the bay and attached to the Station.

Mir Servicing flight. Launch delayed from October 15. Progress docked with Mir, primarily to raise its orbit and preserve the option of a MirCorp-financed flight in 2001. However the funding never came through and the decision was taken to deorbit Mir. Progress M-43 undocked at 0519 GMT on January 25 from the +X Kvant port to clear it for Progress M1-5 (which would deorbit the Mir station). On January 29 Progress M-43 was in a 271 x 280 km x 51.6 deg orbit.

The astronauts installed two 58 kg DDCU DC-to-DC converter units atop the International Space Station's Z1 Truss. The DDCUs, will convert electricity generated by the solar arrays to be attached during the next shuttle mission. The spacewalkers also completed power cable connections on both the Z1 truss and newly installed docking port, PMA-3. They connected and reconfigured cables to route power from Pressurised Mating Adapter-2 to PMA-3 for the arrival of Endeavour and the STS-97 crew next month. They also attached a second tool storage box on the Z1 truss, providing a place to hold the tools and spacewalking aids for future assembly flights. McArthur stocked the boxes with tools and hardware that had been attached to the Unity module. STS-96 Astronauts Tammy Jernigan and Dan Barry had left the tools on the outside of Unity during a May 1999 spacewalk.

Jeff Wisoff and Mike Lopez-Alegria each jetted slowly through space above Discovery's cargo bay, demonstrating the small rescue nitrogen powered SAFER backpack (Simplified Aid for EVA Rescue). This would be used in the future to help a drifting astronaut regain the safety of the spacecraft. Each astronaut performed one 15 meter flight with the SAFER while attached to the shuttle with a long tether. Lopez-Alegria and Wisoff, with Koichi Wakata operating the arm, also completed a series of wrap-up tasks during the EVA. They removed a grapple fixture from the Z1 truss, opened and closed a latch assembly that will hold the solar array truss when it arrives, deployed a tray that will be used to provide power to the U.S. Laboratory Destiny, and tested the manual berthing mechanism latches that will support Destiny. Wisoff opened and closed the latches on the capture assembly for the P6 solar arrays using a pistol grip tool. With it he made more than 125 turns to open the latches, then closed and reopened them. He left the capture latch, called 'the claw,' ready to receive the solar arrays, to be installed by the STS-97 crew. An exercise to test techniques for returning an incapacitated astronaut to the air lock was cancelled because of time constraints.

Military Communications satellite. Launch delayed from October 12 by spacecraft problem. The US Air Force Defense Satellite Communications System satellite was placed by the Centaur upper stage into a 148 km x 898 km x 29.3 deg parking orbit. A second burn put it into a 218 km x 35,232 km x 26.0 deg transfer orbit. The DSCS III B-11 IABS-8 apogee stage, with two Primex R4D liquid apogee engines, circularised the orbit at geostationary altitude on October 21 and then separated from the DSCS.

Mobile Communications satellite. Launch delayed from September 18 and October 19. Stationed at 44 deg E. The first Boeing GEM satellite, Thuraya 1, was built by Boeing/El Segundo (formerly Hughes). It was based on the HS-702 design but featured a large 12-m diameter truss antenna for L-band mobile telephone service. Launch mass of Thuraya was 5108 kg; dry mass probably around 3000 kg. The satellite was to be delivered after on orbit testing to Etisalat, the Emirates Telecom Corp of Abu Dhabi, and its Thuraya Satellite subsidiary. Thuraya was launched from the Odyssey platform in the Pacific Ocean positioned on the equator at 154 deg W. The two-stage Yuzhnoe Zenit core delivered Thuraya and its Energiya Blok DM-SL upper stage to a -2212 x 182 km suborbital trajectory. The first DM-SL burn placed the stack in a 180 x 200 km x 6.3 deg parking orbit at 0604 GMT; a second burn at 0733 GMTput Thuraya in a 210 x 35891 km x 6.3 deg geostationary transfer orbit. A later depletion burn lowered the DM-SL stage perigee to 180 km, as burns by Thuraya's liquid engine raised it towards geosynchronous orbit. Positioned in geosynchronous orbit at 44 deg E in 2000. As of 5 September 2001 located at 44.22 deg E drifting at 0.003 deg E per day. As of 2007 Mar 11 located at 98.57E drifting at 0.007W degrees per day.

Communications satellite. Stationed at 72 deg W. The GE 6 was a Lockheed Martin A2100 series satellite with a mass of 3552 kg at launch and 1900 kg dry. It was to provide broadcast and data services in North America. The DM3 upper stage made two burns and placed the GE 6 in a 5850 x 35726 km x 18.7 deg intermediate transfer orbit at 0441 UTC on October 22. Positioned in geosynchronous orbit at 72 deg W in 2000. As of 3 September 2001 located at 72.01 deg W drifting at 0.008 deg W per day. As of 2007 Mar 11 located at 72.00W drifting at 0.005W degrees per day.

STRV-1c and 1d were small satellites built by the DERA (former Royal Aircraft Establishment), Farnborough, England. Mass was around 95 kg each. STRV-1d carries an NRL Space Test Program experiment (S97-2), a camera, and technology and computer experiments.

The long-delayed Phase 3D amateur radio satellite, built by AMSAT-DL (Germany), was renamed AMSAT-Oscar-40 (AO-40) once launched. It carried an MBB S400 liquid engine (the backup engine for the Galileo Jupiter probe) and a variety of amateur radio payloads in L, S, C, X, V, U and K bands, as well as an ammonia arcjet thruster and a laser communications experiment. The satellite was the largest amateur satellite orbited to date and the first to feature deployable solar panels. Mass was 397 kg dry. The PAS 1R, STRV 1c/1d, and AMSAT Phase 3D satellites were placed in orbit on a single Ariane launch. At 0149 GMT the SBS cylindrical adapter which connected PAS-1R to AMSAT was jettisoned; 50 seconds later AMSAT separated from the EPS upper stage. Thereafter the spacecraft could not be contacted. Finally telemetry was received from after two weeks of silence, confirming that the satellite was still functioning.

The two small STRV cubes were then ejected from the Ariane EPS stage ASAP-5 secondary payload structure at 0141 GMT. STRV-1c and 1d were small satellites built by the DERA (former Royal Aircraft Establishment), Farnborough, England. Mass was around 95 kg each. STRV-1c performed accelerated life testing of new components and materials in the high radiation environment of geosynchronous transfer orbit.

Progress M1-4 was an unmanned resupply craft that rendezvoused with the International Space Station on November 18. After problems with the automatic system, ISS Expedition 1 crew member Gidzenko took over manual control with the remote TORU system at 0302 GMT. The first docking attempt was aborted when M1-4 was only 5 m from the station at 0309 GMT. On the second attempt docking was successfully achieved at 0348 GMT at Zarya's nadir port. The problem on the first attempt was icing of the TORU system TV camera on the Progress when the spacecraft was in shadow. Progress M1-4 undocked from ISS at 1623 GMT on December 1. Following the mission of STS-97 Progress M1-4 redocked to Zarya's nadir port on December 26 at 1054 GMT. The redocking tested a fix to the software that caused problems in the vehicle's first docking attempt on November 18. Yuri Gidzenko completed the docking manually using the remote control TORU system. Progress M1-4 undocked from Zarya's nadir port for the last time at 1126 GMT on February 8. It was deorbited over the Pacific and reentered at 1350 GMT the same day.

The Kosmos-3M second stage entered an 81 x 614 km x 65.8 deg orbit but failed to restart at apogee, and reentered at the next perigee over Uruguay. The loss of the QuickBird 1 satellite was a heavy blow to EarthWatch Inc. QuickBird1 was a 1-m resolution commerical imaging satellite using a Ball Aerospace BCP-2000 bus. Their earlier satellite, EarlyBird, failed after a few days in orbit in December 1997. EarthWatch's rival, SpaceImaging, lost one satellite as well but its second Ikonos was operating in orbit.

First use of a Delta dual payload attach fitting. The Earth Orbiter 1 satellite was part of NASA's New Millenium Program. Complementing the New Millenium's Deep Space series, EO-1 was a NASA-Goddard satellite which demonstrated technology for the next generation Landsat. It flew in formation with Landsat-7 for comparison purposes, using a hydrazine thruster to adjust its orbit. The satellite used a MIDEX-derived bus built by Swales Aerospace; dry mass was 566 kg. The main instruments were ALI (Advanced Land Imager) and the Hyperion 220-band imaging spectrometer. At 1835 GMT the Delta second stage completed its first burn and entered a 185 x 713 km x 98.2 deg transfer orbit. At 1920 GMT the orbit was circularised and EO-1 separated at 1925 GMT into a 682 x 729 km x 98.2 deg orbit.

Heaviest Ariane 4 payload ever. Anik F1 was a Telesat Canada communications satellite. The Boeing model 702 satellite had a launch mass of 4852 kg and a dry mass of 2950 kg. It carried 36 C-band and 48 Ku-band transponders. As of 3 September 2001 located at 107.30 deg W drifting at 0.006 deg W per day. As of 2007 Mar 11 located at 107.29W drifting at 0.000W degrees per day.

The SAC-C Satelite de Aplicaciones Cientificas C was developed by the Argentine space agency CONAE and built by the Argentine company INVAP. The 467 kg satellite carried a battery of earth observing instruments for Argentine forestry and agriculture studies. SAC-C also carried a NASA experiment which used the distortion of GPS signals observed near the horizon to derive atmospheric conditions. The DPAF dual payload support structure, derived from Ariane's SPELDA, was ejected after deployment of the EO-1 satellite from the Delta stage to reveal SAC-C. After a further Delta burn SAC-C was ejected at 1955 GMT into a 687 x 707 km x 98.3 deg orbit.

The small 6 kg Munin nanosatellite was built by Swedish students in collaboration with the Swedish Insitute for Space Physics (IRF) and carried a particle detector, a spectrometer, and an auroral camera. After deployment of EO-1 and SAC-C a fourth burn put the Delta second stage in a 697 x 1800 km x 95.4 deg orbit, after which Munin was ejected from the stage.

Almost three weeks after arriving aboard the International Space Station (ISS), the Expedition One Crew is continuing to activate support systems and unload supplies and equipment from a Progress supply ship that docked to the orbiting facility late last week. Additional Details: here....

Direct Radio Broadcasting satellite. Launch delayed from early October due to delays in delivery of engines. Stationed at 66 deg W. The third Sirius digital radio broadcast satellite was a Loral FS-1300 series vehicle and was placed in an initial elliptical 63 degree orbit by the Proton upper stage. Positioned in geosynchronous orbit at 66 deg W in 2000. As of 30 August 2001 located at 64.69 deg W drifting at 0.027 deg E per day. As of 2007 Mar 10 located at 65.64W drifting at 0.010E degrees per day.

Endeavour was launched on an assembly mission to the to the International Space Station (ISS). The main mission was to install a 72 m x 11.4 m, 65 kW double-wing solar panel on the Unity module of the ISS. The external tank and the Orbiter entered a 74 x 325 km orbit at 0314 GMT. Endeavour's OMS burn raised its perigee to 205 km at around 0347 GMT; the ET re-entered over the Pacific. Endeavour docked with the Station's PMA-3 docking port at 1959 GMT on December 2. Astronauts then installed the P6 solar panel truss to the station during a series of spacewalks. The P6 was made up of the LS (Long Spacer), PV-1 IEA (Integrated Equipment Assembly) and the PVAA (Photovoltaic Array). The LS carried two Thermal Control Systems with radiators to eject waste heat from the Station; these radiators were to be moved to truss segments S4 and S6 later in assembly. The PVAA had solar array wings SAW-2B and SAW-4B, which deployed to a span of 73 meters. Only after completion of three station assembly space walks on December 3, 5, and 7 did the Endeavour crew enter the station (at 1436 GMT on December 8), delivering supplies to Alpha's Expedition One crew. Hatches were closed again at 1551 GMT December 9, and Endeavour undocked at 1913 GMT the same day. After one flyaround of the station, Endeavour fired its engines to depart the vicinity at 2017 GMT December 9. The deorbit burn was at 2158 GMT on December 11, changing the orbit from 351 x 365 km to 27 x 365 km, with landing at Runway 15 of Kennedy Space Center at 2303 GMT.

  • Solar array wing 4B 1070 kg
• Bay 13S: IMAX Cargo Bay Camera 238 kg
• Sill: Canadarm RMS 303 410 kg

The first STS-97 spacewalk began with airlock depress and hatch open at 1831 GMT on December 3. The suits went to battery power at 1835 GMT and Joe Tanner and Carlos Noriega left the airlock around 1845 GMT. Around 1932 GMT the RMS arm berthed P6 on the Z1 truss, and the astronauts manually latched it in place by 1940 GMT. There were some problems releasing latches on the solar array wings, but the first solar array began to deploy at 0123 GMT on December 4. This was the "starboard" (+X) array, wing SAW-2B. The port (-X) array, SAW-4B, was left undeployed. The astronauts closed the hatch at 0202 GMT on Dec 4 and repressurized at 0209 GMT. The P6 PVR radiator was deployed on the +Y side of the IEA at 0414 GMT on December 4. The SAW-4B wing was deployed starting at 0052 GMT on December 5.

Launch delayed from November 28. The Israeli commercial imaging satellite EROS A1 was owned by ImageSat (an Israeli-led company registered in the Netherlands Antilles) and built by IAI using the Ofeq-3 design. EROS A1 was placed in a sun-synchronous orbit together with the DS 5th stage. The 250 kg (dry mass) triaxially stabilized spacecraft carried a black and white high resolution (1.8 m) CCD camera, to obtain images (with terrain width of 12.6 km) of locations chosen by Israeli military or world-wide commercial clients, and downlink them at one of the 14 ground stations.

The spacewalk began on December 5 with depress at 1718 GMT, hatch open around 1719 GMT and battery power at 1721 GMT. Repress was at 2358 GMT. The astronauts connected up P6 to the station, inspected the tension wires on wing 2B, and relocated the S-band antenna to the top of P6. They unlatched the aft TCS radiator, which was deployed sometime early on December 6.

Classified satellite. Launch delayed 24 hours by RL10 engine problem in upper stage. USA 155 was a classified National Reconnaissance Office satellite. The Centaur placed the payload in a 176 x 831 km parking orbit and then in a 270 x 37490 km x 26.5 deg geostationary transfer orbit. The spacecraft was probably either a data relay satellite (to relay spy satellite imagery and data to the ground) and/or a signals intelligence satellite.

Astronauts Noriega and Tanner on December 7 performed EVA-3 to fix the tension in the SAW-2B solar array on the Station. Airlock depress was at 1609 GMT, hatch open at 1610 GMT and battery power at 1613 GMT. The astronauts left the airlock a few minutes later, probably about 1620 GMT. After fixing the solar array they installed the FPPU device to measure plasma conditions near the top of P6 and performed a few other minor tasks. They returned to the airlock at around 2110 GMT, closing the hatch at 2119 and repressurizing at 2122.

After their successful mission to the International Space Station, Endeavour astronauts spent much of Sunday getting ready to land at Kennedy Space Center Monday afternoon. They tested Endeavour's controls and stowed equipment in preparation for their 5:04 p.m. CST landing in Florida. Additional Details: here....

China and Namibia signed an agreement to build a tracking, telemetry and space research station (TTST) in Namibia to support China's manned space program. The station would cover an area of 150 by 85 metres and consist of an administration building and two antennae.

With five times more power than was available just two weeks ago, the Expedition One crew spent the week reconfiguring systems on the International Space Station (ISS) to route electricity being generated from the newly installed U.S. solar arrays on the orbiting complex to the Station's modules. Additional Details: here....

Astra 2D was a Boeing 376HP spin-stabilised satellite, with a dry mass of around 700 kg. It was owned by the Luxembourg-based company SES and was to broadcast to the British Isles. Astra 2D was in a 292 x 35835 km x 2.2 deg transfer orbit on December 22 and was subsequently boosted into geosynchronous orbit by its Star 30 apogee kick motor. The 825 kg (dry mass) satellite carried 16 Ku-band transponders to provide direct-to-home voice, video, and data transmissions to Britain and neighboring countries after parking over 28.2 deg-E longitude. Positioned in geosynchronous orbit at 28 deg E in 2001 As of 3 September 2001 located at 28.17 deg E drifting at 0.014 deg E per day. As of 2007 Mar 10 located at 28.17E drifting at 0.014W degrees per day.

Second Beidou-1 geosynchronous navigation satellite. The CZ-3A rocket's third stage put Beidou in geostationary transfer orbit at around 16:42 GMT. The Beidou satellite was based on the DFH-3 comsat and had a mass of around 2200 kg including its FY-25 solid apogee motor. On December 25 Beidou was in a 190 x 41870 km x 25.0 deg transfer orbit. The launch of this second Beidou completed the prototype two-satellite navigational system which was to provide positional information for highway, railway and marine transportation. Positioned in geosynchronous orbit at 80 deg E, still maintaining its position within 0.1 deg as of 2007. Retired after launch of the Beidou-2 geosynchronous satellites in 2010.
