Proton 8K82K 8K82K with Almaz-K payload - COSPAR 1991-024

AKA: 8K82K;D-1;Proton 3;SL-13;UR-500K. Status: Retired 2000. First Launch: 1968-11-16. Last Launch: 2000-07-12. Number: 30 . Payload: 19,760 kg (43,560 lb). Thrust: 8,847.00 kN (1,988,884 lbf). Gross mass: 693,810 kg (1,529,580 lb). Height: 50.00 m (164.00 ft). Diameter: 4.15 m (13.61 ft). Span: 7.40 m (24.20 ft). Apogee: 186 km (115 mi).

Development of a three-stage version of the UR-500 was authorized in the decree of 3 August 1964. During development, in comparison to the original polyblock design, the engine performances were improved by about 5 seconds; the mass of the first stage increased by 71 metric tons; the second stage by 30 metric tons; and the third stage by 27 metric tons (more than doubled). These changes brought the low earth orbit payload from 12,000 kg up to almost 20,000 kg. The UR-500K, although it exceeded the launch mass of the 11A511 Soyuz by 2.22 times and the fuel mass by 2.25 times, was more efficient with a useful load by 2.78 times greater. However putting the new variant of Proton into service proved difficult.

Decrees of 12 October and 11 November 1964 authorized development of the Almaz manned military space station and the manned circumlunar spacecraft LK-1 as payloads for the UR-500K. However at the same time Khrushchev was ousted from power. Chelomei lost his chief patron and his projects came under negative scrutiny by the new leadership.

Although Korolev was opposed to the Proton, he now used it to his advantage. On 8 September 1965 Korolev presented several schemes for using Chelomei's UR-500K to fly around the moon. One alternate was a two-part spaceship, using the Proton with the upper stage Block D from Korolev's N1-L3 lunar project. This would launch Korolev's 7K-L1 spacecraft (derived from the 7K-OK Soyuz spacecraft) onto a translunar trajectory. This project received the name UR-500K-L1, and was adopted in place of Chelomei's LK-1. It required construction of 18 UR-500K rockets, which, in a combination flight-test and government trials program, would send L1 spacecraft around the moon, at first unmanned, then manned.

As a result of Korolev's seizure of the project, the first flights of the three stage Proton included Korolev's fourth Block D stage. Due to delays in the Almaz military space station, it was pre-empted by an OKB-1 civilian derivative, the Zarya. The first launch of the basic three-stage UR-500K vehicle, without the Block D upper stage, did not come until the launch of the Proton 4 physics satellite, almost two years after flights of the four-stage version had begun.

Remarkably, due to continuing failures, the 8K82K did not satisfactorily complete its state trials until its 61st launch (Salyut 6 / serial number 29501 / 29 September 1977). Thereafter it reached a level of launch reliability comparable to that of other world launch vehicles.

LEO Payload: 19,760 kg (43,560 lb) to a 186 km orbit at 51.60 degrees. Launch Price $: 50.000 million in 1994 dollars.

• Chief Designers review of Voskhod at OKB-1 - . Nation: Russia. Related Persons: Chelomei, Khrushchev, Sergei. Program: Voskhod. Flight: Voskhod 1. Spacecraft: LK-1, Voskhod.

  All concerned designers, bureaux, and institutes certify the reliability of the systems of the spacecraft and launch vehicle. The second phase of trials of the soft landing system have been successful. Of 10 drops, 9 landed with vertical velocity under 7.5 m/s, and of those, 6 landed with a speed of only 0.0 to 1.5 m/s. There are still concerns about how the system will function in soft soils or adverse weather conditions. Nevertheless the decision is taken to ship the spacecraft to the cosmodrome for final preparations between 18 and 25 August. It is likely that the manned flight cannot occur until the end of September. Later in the day Kamanin is visited by Sergei Nikitovich Khrushchev and other experts from Chelomei's design bureau. They brief Kamanin on plans for a manned circumnavigation of the moon using their spacecraft launched by their UR-500 booster by the end of 1967.

• Almaz project starts - . Nation: Russia. Related Persons: Chelomei. Spacecraft: Almaz APOS, Soyuz R.

  The day before the overthrow of his patron, Chelomei obtained permission to begin development of a larger military space station, the Almaz. This 20 tonne station would take three cosmonauts to orbit in a single launch of his UR-500K Proton rocket. Therefore there were now two competing projects for the same mission - Almaz and Soyuz-R. First flight of the Almaz, with a one year operational period, was set for 1968.

• Development of the manned circumlunar spacecraft LK-1 authorised - . Nation: Russia.

• Cosmonaut training for lunar flights announced - . Nation: Russia. Related Persons: Leonov. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1. Leonov announces that cosmonauts are in training for lunar missions..

• Lunar flight cosmonauts assignments. - . Nation: Russia. Related Persons: Artyukhin, Beregovoi, Bykovsky, Dobrovolsky, Gagarin, Gorbatko, Grechko, Khrunov, Klimuk, Kolodin, Komarov, Kubasov, Leonov, Makarov, Nikolayev, Popovich, Rukavishnikov, Sevastyanov, Shatalov, Volkov, Voloshin, Volynov, Voronov, Yeliseyev, Zholobov. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1.

  In the period 1966 to 1968 there were five simultaneous Soviet manned space projects (Soyuz 7K-OK orbital; Soyuz 7K-L1 circumlunar; Soyuz VI military; L3 manned lunar landing; Almaz space station). Cosmonaut assignments were in constant flux, resulting in many claims in later years that 'I was being trained for the first moon flight'. Additional Details: here....

• First session of State Commission for the L1 - . Nation: Russia. Related Persons: Barmin, Chelomei, Mishin, Tyulin. Program: Lunar L1. Flight: Soyuz 7K-L1 mission 1, Soyuz 7K-L1 mission 2, Soyuz 7K-L1 mission 3. Spacecraft: Soyuz 7K-L1, Soyuz 7K-OK.

  Tyulin chairs the meeting. Mishin, Chelomei and Barmin brief the status of the spacecraft, booster, and launch site. There is much to be done in order to fly cosmonauts around the moon by 7 November 1967 - the 50th anniversary of the October Revolution. The first manned flight around the moon is planned for 26 June 1967. To achieve this, four flights of the L1 without a crew have to be completed first. The UR-500K booster should be capable of launching the L1 on a direct flight around the Moon and back to the earth. But since the UR-500K has not yet flown, and its 19-tonne low earth payload has not bee verified, Mishin plans to follow the podsadka scenario. The UR-500K will place in low earth orbit an L1 without a crew, and then a Soyuz booster will place a manned Soyuz 7K-OK Soyuz in orbit. The Soyuz crew will rendezvous and dock with the L1, and the crew for the circumlunar mission will spacewalk through open space from the 7K-OK into the L1. The spacecraft will then separate. The 7K-OK returns to earth, while the L1 is boosted on a circumlunar trajectory. After 4 to 6 launches of the UR-500K to verify its reliability and payload margins, it should be possible to make the direct flight to the moon on subsequent versions. For the time being it is necessary to develop both versions in parallel.

• First L-1 Zond spacecraft mated to Proton - . Payload: Soyuz 7K-L1P #1. Nation: Russia. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1. Fit tests at Tyuratam. Not launched (Interavia SD)..

• Soviet of Chief Designers - . Nation: Russia. Related Persons: Chelomei, Dementiev, Glushko, Mishin, Ustinov. Program: Lunar L1, Soyuz. Spacecraft: Soyuz 7K-L1, Soyuz 7K-OK.

  In Moscow, Mishin heads a meeting of all the Chief Designers (including Chelomei, Mishin, and Glushko). Glushko says that the last UR-500K failure was due to errors made during manufacture of an engine in 1965 at Factory 19 at Perm. Ustinov notes that the failure has cost the state 100 million roubles and has delayed the program two to three months. He brutally attacks Dementiev, Minister of Aviation Industry, for the poor work of his factories on the space program. Another issue is continued delays in the Salyut computer for the L1. Ustinov orders an alternate technical solution to be developed in parallel with the digital computer development. The next Soyuz flight is set for the end of December, the next L1 attempt for 21-22 November.

• UR-500 launch vehicle version for military payloads authorised. - . Nation: Russia. Central Committee of the Communist Party and Council of Soviet Ministers Decree 1070-363 'On approval of work on the UR-500 launch vehicle' was issued..

• Cause of Proton failure in last launch. - . Nation: Russia. Related Persons: Glushko. Program: Lunar L1. Glushko at Baikonur. He reports the Perm factory is under close supervision - the engine that failed on the last launch was found to have resin in the main fuel line..

• DIA/CIA warn of impending Zond circumlunar flight - . Nation: Russia. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1.

  The information led NASA to decide to send Apollo 8 on a risky lunar orbital mission at the end of December 1968. Interestingly enough the CIA warning to NASA came within days of the L1 State Commission's meeting and decision to press for a November circumlunar flight.

• Zond 7K-L1 s/n 8L - . Payload: Zond 7K-L1 s/n 8L. Mass: 5,140 kg (11,330 lb). Nation: Russia. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz.

  Brezhnev orders a cooperative crash program to build a civilian space station to beat Skylab into orbit. The civilian station (later named Salyut) will use the Almaz spaceframe fitted out with Soyuz functional equipment. Mishin's OIS military station was cancelled and Chelomei's Almaz would continue, but as second priority to the civilian station. The Soyuz 7K-S station ferry, the 7K-ST, would be revised to be a more conservative modification of the Soyuz 7K-OK. The OIS cosmonaut group was incorporated into the Almaz group.

• Development of TKS ferry for Almaz authorised. Soyuz 7K-TK cancelled - . Nation: Russia. Related Persons: Chelomei. Spacecraft: Soyuz 7K-TK, TKS.

  Decree 437-160 'On creation of the TKS and termination of the 7K-TK' was issued. In 1969 Chelomei proposed replacement of the 11F72 Soyuz 7K-TK with his own transport-supply spacecraft 11F72 (transportnovo korablya snabzheniya - TKS). This would consist of the same 11F74 VA landing capsule used on the Almaz station, together with a new 11F77 functional-cargo block (funktsionalno-gruzovovo blok, FGB). This would transport three crew and sufficient supplies for 90 day operation of the Almaz.

Despite decision to cancel immediate manned circumlunar flights after Apollo 8, the remaining two L-1 spacecraft were kept in reserve for support of the L3 lunar landing program and possible later manned flights. They were never used..

• Salyut 1 - . Payload: Zarya s/n 121. Mass: 18,500 kg (40,700 lb). Nation: Russia. Agency: MOM. Program: Salyut. Class: Manned. Type: Manned space station. Flight: Soyuz 10, Soyuz 11, Soyuz 12 / DOS 1. Spacecraft Bus: Almaz. Spacecraft: Salyut 1. Duration: 179.93 days. Decay Date: 1971-10-11 . USAF Sat Cat: 5160 . COSPAR: 1971-032A. Apogee: 214 km (132 mi). Perigee: 180 km (110 mi). Inclination: 51.40 deg. Period: 88.50 min.

  First manned space station. Salyut 1 included a number of military experiments, including the OD-4 optical visual ranger, the Orion ultraviolet instrument for characterising rocket plumes, and the highly classified Svinets radiometer. Primary objectives included photography of the earth, spectrographs of the earth's horizon, experiments with intense gamma rays, and studying manual methods for station orientation.

  At 05:20 the State Commission and their guests arrive at the Area 95 observation point to view the launch. The booster takes off on schedule at 06:40 in light rain and 60 km/hr wind. The tracking station reports good orbital insertion, separation from the third stage, and antennae and solar panel deployment. But the cover of the scientific equipment bay does not separate. This will mean that many experiments cannot be accomplished. It is decided to launch the crew to the station anyway, since the station is otherwise functioning normally. The cosmonauts go to the baths in the evening. Additional Details: here....

Period: 89.10 min.

  The first flight of the Almaz manned military space station. In January 1973 the first Almaz OPS was delivered to Baikonur. Launch and initial orbital checkout went according to plan. But before a crew could be launched the station depressurized. It was concluded that a short in electrical equipment started a fire in pressure vessel, leading to rupture of hull and depressurization. An alternate theory was that debris from an explosion of the third stage of Proton penetrated the hull. Control was lost on April 25, 1973, and the OPS cased operations on 29 April. Decayed May 28, 1973. Initial crew was to have been Popovich and Artyukhin.

Period: 89.10 min.

  First successful Almaz military manned space station flight. Tested a wide array of reconnaissance sensors. Following the successful Soyuz 14 and unsuccessful Soyuz 15 missions, on 23 September 1974 the station ejected a film return capsule. The KSI capsule suffered damage during re-entry but all the film was recoverable. On 24 January 1975 trials of the on-board 23 mm Nudelmann aircraft cannon (other sources say it was a Nudelmann NR-30 30 mm gun) were conducted. The next day the station was commanded to retrofire to a destructive re-entry over the Pacific Ocean. Although only one of three planned crews managed to board the station, that crew did complete the first completely successful Soviet space station flight. Additional Details: here....

Spacecraft: Almaz OPS. Duration: 411.24 days. Decay Date: 1977-08-08 . USAF Sat Cat: 8911 . COSPAR: 1976-057A. Apogee: 232 km (144 mi). Perigee: 215 km (133 mi). Inclination: 51.60 deg. Period: 88.90 min.

  Second successful flight of the Almaz manned military space station. It had taken only 60 days and 1450 man-hours to prepare Almaz 0101-2 for flight, using the services of 368 officers and 337 non-commissioned officers. The tracking ships Academician Sergei Korolev and Cosmonaut Yuri Gagarin were stationed in the Atlantic and Caribean to provide communications when out of tracking range of the USSR. Salyut 5 operated for 409 days, during which the crews of Soyuz 22 and 24 visited the station. Soyuz 23 was to have docked but its long-distance rendezvous system failed. Soyuz 25 was planned, but the mission would have been incomplete due to low orientation fuel on Salyut 5, so it was cancelled.

  During the flight of Salyut 5 a 'parallel crew' was aboard a duplicate station on the ground. They conducted the same operations in support of over 300 astrophysical, geophysical, technological, and medical/biological experiments. Astrophysics studies included an infrared telescope-spectrometer in the 2-15 micrometer range which also obtained solar spectra. Earth resources studies were conducted as well as Kristall, Potok, Diffuziya, Sfera, and Reatsiya technology experiments. Presumably Salyut 5 was equipped with a SAR side-looking radar for reconnaissance of land and sea targets even through cloud cover.

  The film capsule was ejected 22 February 1977 (and sold at Sotheby's, New York, on December 11, 1993!). The station was deorbited on 8 August 1977. In addition to the human crew two Russian tortoises (Testudo horsfieldi) and Zebrafish (Danio rerio) were flown.

  The results of the Salyut 3 and 5 flights showed that manned reconnaissance was not worth the expense. There was minimal time to operate the equipment after the crew took the necessary time for maintenance of station housekeeping and environmental control systems. The experiments themselves showed good results and especially the value of reconnaissance of the same location in many different spectral bands and parts of the electromagnetic spectrum.

  Launch of mission LVI-1 came at 04:00 on 15 December. At 176 seconds the ADU escape tower separated from the LVI. Once the final stage had shut down in orbit, by command from the launch vehicle sequencer, the VA 009A (also given as 009P) and its TDU separated from the LVI. Two seconds later VA 009 (or 009L) was ejected. Fifteen minutes after launch all systems of the both VA capsules were in operation. The guidance system detected the direction of flight and oriented each spacecraft for retro-fire, and the pair began the return to earth after less than one revolution. At an external atmospheric pressure of 165 mm (10 km altitude) the NO section jettisoned, the three-cupola drogue parachute ejected, and the antennae and altimeter were deployed. The Komara landing radio beacon (installed on the landing section of the parachute) was activated when the spacecraft was 1.0 to 1.5 m above the ground - which occurred at the same moment on both 009 and 009A. The Kaktus special system tripped the soft landing PRSP (parachute landing propulsion system). The soft landing was accomplished with higher accuracy than Soyuz, both capsules being recovered at 44 deg N, 73 deg E, on December 15, 1976 3:00 GMT. The flights were officially given the designations Cosmos 881 (VA 009A) and Cosmos 882 (VA 009). US intelligence believed them to be tests of recoverable manned spaceplane prototypes.

  Given the on-pad explosion of the LVI-2 launch attempt, plans to crew the upper VA re-entry capsule in the next test was abandoned. LVI-3 (VA's 102P and 102L / Cosmos 997 and Cosmos 998) was launched unmanned four months behind the original schedule. Both capsules were recovered after one orbit. One source indicates that one of the capsules was 009P, on its third launch and second flight to orbit. This was said to have demonstrated the multiple re-entry capability of the heat shield and the first planned reuse of a spacecraft (Gemini 2 was refurbished and reflown as MOL-1 in the 1960's, but was not designed for that purpose).

  The Proton launch vehicle that shut down on the original LVI-4 launch attempt was undamaged, and just a month later, with a switch of payload, LVI-4 was orbited as Cosmos 1100 and 1101. The pair launched were the 102P/102L twins from LVI-3. One capsule failed when the automatic system suffered an electrical distribution failure and it did not land correctly, spending two orbits in space, while the other landed as planned after one orbit. The launch again successfully demonstrated the reusability of the VA capsule. Plans to launch the upper capsule manned were scrubbed due to the inability to get two consecutive failure-free launches of the Proton/TKS-VA.

Objectives: Continuation of scientific research on board manned space complexes in the interests of science and the Soviet national economy; testing of advanced systems and apparatus for orbital stations. Continuation of the scientific research in progress on board manned space complexes in the interests of science and the national economy; testing of advanced systems and apparatus for orbital stations. Although of the same design as Salyut 6, technical breakdowns throughout its life made Salyut 7 a much less productive station. Replaced finally by Mir. Two different TKS resupply craft, originally designed for the Almaz military station, docked with Salyut 7 to provide a larger complex. With the cancellation of Almaz, a large proportion of the experiments carried out on board had military objectives. As of January 1990 out of fuel, unable to manoeuvre, uncontrolled re-entry expected in three to four years. Re-entered in 1991 with 70 kg fuel remaining over Argentina. Controllers attempted to control impact point (set for Atlantic Ocean) by setting Salyut 7/Kosmos 1686 assembly into a tumble. This however failed and Salyut 7 re-entered February 7, 1991 04:00 GMT. Many fragments fell on the town of Capitan Bermudez, 25 km from Rosario and 400 km from Buenos Aires, Argentina. At 1 am local time the sky was lit up with hundreds of incandescent meteors travelling from Southwest to Northeast. At dawn the inhabitants discovered numerous metal fragments, which seemed to have fallen in distinct groups at various locations in the city. Luckily no one was hurt in the metallic shower.

  This was the first launch in the assembly of the International Space Station. The Zarya FGB was funded by NASA and built by Khrunichev in Moscow under subcontract from Boeing for NASA. Its design from the TKS military station resupply spacecraft of the 1970's and the later 77KS Mir modules. Zarya included a multiple docking adapter, a pressurised cabin section, and a propulsion/instrument section with a rear docking port. Initial orbit was 176 lm x 343 km x 51.6 degrees. By November 25 it had manoeuvred to a 383 km x 396 km x 51.7 degree orbit, awaiting the launch of Shuttle mission STS-88 which docked the Unity node to it.

• Zvezda - . Mass: 20,295 kg (44,742 lb). Nation: Russia. Agency: RAKA. Manufacturer: Chelomei bureau, Korolev bureau. Program: ISS. Class: Manned. Type: Manned space station. Spacecraft Bus: ISS. Spacecraft: ISS Zvezda. USAF Sat Cat: 26400 . COSPAR: 2000-037A. Apogee: 332 km (206 mi). Perigee: 179 km (111 mi). Inclination: 51.60 deg.

  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.
