Associated Launch Vehicles
  • Delta 3920/PAM American orbital launch vehicle. Four stage vehicle consisting of 9 x Castor 4A + 1 x ELT Thor/RS-27 + 1 x Delta K + 1 x Star 48B More...
  • Ariane 44L French orbital launch vehicle. Ariane 4 with 4 liquid rocket strap-ons. More...
  • Atlas I American orbital launch vehicle. The Atlas I launch vehicle was derived from the Atlas G, and included the same basic vehicle components (Atlas booster and Centaur upper stage). Significant improvements in the guidance and control system were made with an emphasis on replacing analog flight control components with digital units interconnected with a digital data bus. More...

  • Delta 7925 American orbital launch vehicle. Four stage vehicle consisting of 9 x GEM-40 + 1 x EELT Thor/RS-27A + 1 x Delta K + 1 x Star 48B More...
  • Atlas IIA American orbital launch vehicle. Atlas IIA was a commercial derivative of the Atlas II developed for the US Air Force. Higher performance RL10A-4 (or RL10A-4-1) engines replaced Atlas II's RL10A-3-3A engines. More...
  • Ariane 42L French orbital launch vehicle. Ariane 4 with 2 liquid rocket strap-ons. More...
  • Atlas IIAS American orbital launch vehicle. The Atlas II booster was 2.7-meters longer than the Atlas I and included uprated Rocketdyne MA-5A engines. The Atlas I vernier engines were replaced with a hydrazine roll control system. The Centaur stage was stretched 0.9-meters compared to the Centaur I stage. Fixed foam insulation replaced Atlas I's jettisonable insulation panels. Higher performance RL10A-4 or RL10A-4-1 engines replaced Atlas II's RL10A-3-3A. The Atlas IIAS model added four Thiokol Castor IVA solid rocket boosters (SRBs) to the core Atlas stage to augment thrust for the first two minutes of flight. More...
  • Delta 7925-8 American orbital launch vehicle. Four stage vehicle consisting of 9 x GEM-40 + 1 x EELT Thor/RS-27A + 1 x Delta K + 1 x Star 48B with 2.4 m (8 foot) diameter fairing) More...
  • Ariane 5G French orbital launch vehicle. Initial version of the Ariane 5, a bit too large for the main commercial geosynchronous communications satellite payloads. More...
  • Delta 3 American orbital launch vehicle. Delta 3 was an attempt by the manufacturer to provide the ultimate development of the original Delta booster. The core vehicle was beefed-up to accomodate much larger solid rocket boosters and a new cryogenic upper stage. However problems were incurred during development, resulting in the first two launches being failures. Meanwhile the satellite launch market crashed and the new vehicle was left without customers. The venerable Delta 7925 soldiered on for NASA, and the new Delta 4 series captured the USAF EELV requirement. More...
  • Zenit-3SL Ukrainian orbital launch vehicle. From the beginning of the program a Zenit-3 version was proposed for geosynchronous launches using the N1/Proton Block D third stage. This had the potential of replacing the Proton in the role of geosynchronous launcher. It was considered for launch from Australia / Cape York in the 1980's. Finally a joint US-Norwegian-Ukraininan-Russian consortium was formed to launch the three stage commercial Zenit from the Odyssey floating launch platform in the Pacific Ocean. More...
  • Soyuz FG Uprated Soyuz booster designed for high performance Russian government missions and delivery of Soyuz and Progress spacecraft to the International Space Station. Upgraded engines, modern avionics, reduced non-Russian content. Unknown differences to Soyuz ST. More...
  • Ariane 5ECA French orbital launch vehicle, first version of the evolved Ariane 5. The solid booster motors propellant load was increased by 2.43 tonnes and the case was welded, for a weight saving in dry mass of 1.9 tonnes. The core was powered by an improved Vulcain 2 engine. The oxygen-rich cycle of the engine allowed the oxygen bulkhead to be moved within the stage, resulting in a 15.2 tonne increase in propellant in the core. A new Lox/LH2 upper stage, using the HM7B engine and oxygen tank from the Ariane 4 series, replaced the storable propellant EPS stage of earlier models. The result was an increase in payload to geoscynchronous transfer orbit from 6 tonnes to 10.5 tonnes. More...

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur. More...
  • Kourou After the agreement with newly independent Algeria for France to evacuate their launch sites in that country, a location near Biscarosse was selected for French missile testing. However since only launches westwards across the Bay of Biscay could be made from this site, it was unsuitable for France's Diamant orbital launch vehicle. After reviewing 14 potential sites, a location in the South American French colony of Guiana was selected. This would allow over-water launches to a tremendous range of possible orbital inclinations -- from -100.5 deg to 1.5 deg. Being near the equator, it would provide the maximum assist from the earth's rotation for launches into equatorial orbits. The decision was formalized in April 1964 and in July 1966 ELDO chose the site for future launches of the Europa II launch vehicle. More...
  • Kiritimati Kiritimati (Christmas Island) in the Pacific Ocean was originally selected by Von Braun in his Collier magazine series of the early 1950's as an ideal equatorial launch site. A half century later, Boeing Sea Launch used an offshore location for orbital launches. The launch platform was a seagoing converted Norwegian offshore oil rig. Between missions it was berthed in Long Beach, California. It was towed to a location off Kiritimati for launches of the Ukrainian Zenit-3 launch vehicle. More...

  • Galaxy 3C - . Mass: 4,850 kg (10,690 lb). Nation: USA. Agency: PanAmSat. Manufacturer: El Segundo. Program: Galaxy. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 702. USAF Sat Cat: 27445 . COSPAR: 2002-030A. Apogee: 35,788 km (22,237 mi). Perigee: 35,786 km (22,236 mi). Inclination: 0.1000 deg. Period: 1,436.10 min. 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.
