Classified satellite for the National Reconnaissance Office. It was likely that it was a technology test satellite combining equipment for several future projects, including a prototype COBRA BRASS infrared early warning satellite sensor. The project seemed to have been several years behind schedule (based on the launch vehicle serial number.
UHF Follow-On F8 was the first Block III UHF Follow-On satellite, replacing the old FLTSATCOM satellites. It carried UHF, EHF and Ka-band transponders, including a video broadcast payload. This was the last Atlas II launch; future Atlas launches would use the Atlas IIA, IIAS and III models. Positioned in geosynchronous orbit at 172 deg E in 1998-1999.
The spacecraft was delivered to its final orbit in a complex series of five engine burns by three rocket stages. The Delta's second stage demonstrated its restart capability in 4 burns: Burn 1 placed the rocket and payload into a low circular orbit; Burn 2 raised the apogee to 1400 km; Burn 3 circularised the orbit at 1400 km. The second stage then separated, and Burn 4 lowered the spent stage's perigee to a low altitude to ensure the stage would decay quickly and not add to the space junk already on orbit. Stage 3 burned once to place the payload and its kick motor into a high 1400 km perigee geosynchronous transfer orbit. The Stage 4 Star 30 apogee kick motor circularised the spacecraft's orbit at geostationary altitude. Geostationary at 0.8 degrees W. Positioned in geosynchronous orbit at 1 deg W in 1998-1999 As of 4 September 2001 located at 0.83 deg W drifting at 0.000 deg E per day.

Built by Hughes/El Segundo for Panamsat. The satellite carried 24 C-band and 24 Ku-band transponders to provide US/Caribbean coverage, and was to have replaced the ageing SBS-5 satellite at 123 deg West. Replenishing the Galaxy/PAS constellation was a high priority for Panamsat following the loss of Galaxy 4 and problems with Galaxy 7. Galaxy 11 was not scheduled to go up until the first launch of the Sea Launch Zenit-3SL in early 1999, and this booster was in limbo due to legal problems with unauthorised transfer of technical data from Boeing to Russia. In addition there were several PAS satellites awaiting launch over the next year on Proton and Ariane vehicles.
The first burn of the Proton's Block DM3 put the spacecraft into a 220 x 36,007 km x 51.6 deg transfer orbit.

The satellite carried UHF and EHF transponders for naval communications, and a Ka-band Global Broadcast Service video relay package. Launch mass of 3200 kg dropped to 1550 kg once geostationary orbit was reached. UHF F/O F9 was placed over the Atlantic Ocean in geosynchronous orbit at 174 deg W in 1998; 22 deg W in 1999.

The satellite was to provide more than 300 local TV channels to 41 metropolitan communities through its 11 C-band transponders after parking over 101-W longitude. As of 2007 Mar 9 located at 101.14W drifting at 0.005W degrees per day.
Launch delayed from October 31, November 13 and 26, 2001 and February 6 due to contract dispute with Boeing over performance of earlier satellites of the series. The Centaur upper stage entered a 167 x 578 km parking orbit and then placed the payload into a 247 x 29135 km x 27.1 deg subsynchronous transfer orbit. NASA's TDRS-I (TDRS-9) data relay satellite used a Boeing BSS-601 bus and was to provide S, Ku and Ka band communications for the Shuttle and International Space Station. After launch a problem developed with the fuel supply from one of the satellite's four propellant tanks. The tanks were paired, so losing one tank cuts the propellant supply in half. A test burn of the General Dynamics R-4D apogee motor raised the orbit to 433 x 29146 km x 26.4 deg on March 11 and a larger perigee burn raised the apogee to geostationary altitude, 429 x 35800 km, on March 13. A further burn on March 19, raised the orbit to 3521 x 35789 km and lowered the inclination to 21.4 deg. A burn on March 25 raised the orbit further to 8383 x 35811 km and lowered inclination to 17.4 deg. As of 2007 Mar 11 located at 62.04W drifting at 0.008W degrees per day.
Communications satellite. Launch delayed from mid-March. After the Ariane third stage reached geostationary transfer orbit, JCSAT 8 separated, followed by the Mini-Spelda adapter, followed by Astra 3A. Astra 3A was a Boeing BSS-376HP, with a mass of 1495 kg full and about 750 kg empty. It joined Luxembourg-based SES Astra's fleet. As of 2007 Mar 9 located at 153.96E drifting at 0.004W degrees per day.
Communications satellite. Launch delayed from mid-March. JCSAT 8 was a Boeing BSS-601 with a launch mass of 2600 kg and a dry mass around 1200 kg. It was to be used by Japan Satellite to replace JCSAT 2. As of 2007 Mar 10 located at 24.29E drifting at 0.020W degrees per day.
Launch delayed from July 2001 and May 28, June 2 and 9, 2002. The Galaxy 3C satellite was launched from the Odyssey floating launch platform at its standard 154W 0N location. The Zenit second stage and the DM third stage with payload entered a -2160 x 195 km suborbital trajectory at 2248:10. At about 2252 UTC the DM stage entered a 180 x 393 km x 0 deg parking orbit. A second burn of the DM at 2324 to 2330 UTC put Galaxy 3C in a 358 x 41440 km x 0.02 deg transfer orbit This was a record low inclination for a geostationary transfer orbit. The satellite's R-4D apogee engine was to put the Boeing BSS-702 satellite in geostationary orbit. The satellite was the first 702 model to use extra solar panels instead of the solar concentrators which ran into fogging problems on the earlier 702 flights. As of 2007 Mar 10 located at 95.06W drifting at 0.007W degrees per day.
Delayed from October 29, November 21 and 23. The third and final Advanced Tracking and Data Relay Satellite satellite separated from the Centaur upper stage 30 minutes after launch. This completed the $800 million, three satellite contract. Last launch of the Atlas 2A booster. Flight delayed from October 29, November 21 and 23. As of 2007 Mar 10 located at 40.92W drifting at 0.012E degrees per day.
Delayed from May 28, 2002, and January 13, February 5, and April 11, 2003. AsiaSat 4 was designed to provide broadcast, telecommunications and broadband multimedia services to the Asia Pacific region, and direct-to-home broadcast servic-es to Hong Kong, from its orbital position of 122 deg É East longitude.The satellite generated up to 9,600 watts using two sun-tracking four-panel solar wings covered with triple-junction gallium arsenide solar cells. AsiaSat 4 was to operate in C-band and Ku-band. The satellite carried 28 active transponders with six spares in C-band, powered by 55-watt traveling-wave tube amplifiers (TWTAs), and 20 active transponders with four spares in Ku-band, powered by 140-watt TWTAs. The C-band payload was designed to offer pan-Asian coverage, similar to AsiaSat 3S, also a 601HP model. The Ku-band payload provided high power, and spot beams for selected areas in either the Fixed Satellite Service frequency band or in the Broadcast Satellite Service frequency band. As of 2007 Mar 10 located at 122.23E drifting at 0.011W degrees per day.
Heaviest total commercial GTO payload to that date. Qualification flight for the Ariane 5 EC-A version. Launch delayed from June 25 due to launch vehicle problems. Spaceway 2 launch delayed from April for problems with the satellite. As of 2007 Mar 10 located at 99.24W drifting at 0.010W degrees per day.
The platform was designed to survive such an explosion, but the flame deflector was blown off and the blast doors unhinged. The launch platform was towed back to Long Beach for repairs. The time required to repair the platform and the investigation to determine and fix the cause would certainly impact the 2007 Zenit-3SL and Zenit-2 launch schedules, probably forcing customers to be diverted to other boosters. NSS-8 was to have been placed at a 57º East orbital position to satisfy demand in the Indian Ocean region with 56 C-band and 36 Ku-band transponders. NSS-703, with an expected end-of-life in 2009, would have to continue in service until a replacement was built and launched.
