Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II the most reliable launch system in history.
Lockheed Martin's Space Division started in the production of missiles and later ICBM's in the 1950s. Their TITAN missile system was used for 12 Gemini spacecraft and the Voyager probes. They have worked largely in collaboration with NASA on many of their probes, landers, and spacecraft, and hope to play a key role in NASA's return to the moon in 2024.
TDRS-9, known before launch as TDRS-I, is an American communications satellite which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by the Boeing Satellite Development Center, formerly Hughes Space and Communications, and is based on the BSS-601 satellite bus.[3] It was the second Advanced TDRS, or second-generation Tracking and Data Relay Satellite, to be launched.
Geosynchronous Transfer OrbitThe Geostationary Operational Environmental Satellites were developed by NASA-Goddard and were transferred to the NOAA weather agency when operational. In addition to the usual weather imager/sounder, GOES-M carried a new solar soft X-ray imager.
Supersynchronous Transfer OrbitDSCS-3 (Defense Satellite Communications System 3) are geostationary communications satellites, which provide a robust anti-jam, nuclear hardened capability that supports Department of Defense (DoD) worldwide requirements, White House and Diplomatic communications. They are the follow-on generation of the DSCS-2 satellites.

Geostationary OrbitThe U.S. Navy began replacing and upgrading its ultra-high frequency (UHF) satellite communications network during the 1990s with a constellation of customized satellites built by Hughes Space and Communications Company. Known as the UFO (Ultra High Frequency Follow On) series, these HS-601 model satellites support the Navy's global communications network, serving ships at sea and a variety of other U.S. military fixed and mobile terminals.

Geostationary OrbitSatellite Data System (SDS) spacecraft are communication relay satellites for transmitting real-time data from US reconnaissance satellites (e.g. KH-11, Onyx, Topaz) in polar areas. They are also used for communications to USAF aircraft on polar routes and connect the various ground stations of the Air Force Satellite Control Network (AFSCN). The spacecraft relay the downlinked data to a ground station at Fort Belvoir, Virginia.
Elliptical OrbitDSCS-3 (Defense Satellite Communications System 3) are geostationary communications satellites, which provide a robust anti-jam, nuclear hardened capability that supports Department of Defense (DoD) worldwide requirements, White House and Diplomatic communications. They are the follow-on generation of the DSCS-2 satellites.
Geostationary OrbitThe Tempo 1 and 2 satellites can transmit more than 200 channels of high-fidelity broadcast programming to cable companies and home dishes. Tempo has twice the power and capacity of comparable satellites. It features 32 high-powered Ku-band transponders at 115 Watts, switchable to 16 transpondersders at 220 Watts. Total on-board transmitter power totals 3500 Watts.
Geostationary OrbitLaunched in 1996-8, the Inmarsat-3s were built by Lockheed Martin Astro Space (now Lockheed Martin Missiles & Space) of the USA, responsible for the basic spacecraft, and the European Matra Marconi Space (now Astrium), which developed the communications payload.
Geostationary OrbitGE-1 is owned by GE Americom and is a continuation of the old RCA/GE Satcom series. GE-1 has 24 C-band and 24 Ku-band transponders, and replaced Satcom K1. GE-1 was placed in a supersynchronous transfer orbit of 191 × 56495 km × 25.0 deg.

Geostationary OrbitThe Orion 1 telecommunications satellite, launched in November 1994, was the first purchase of a European satellite by a US-based company. Its 34 Ku-band transponders serve Europe, the United States to the Rocky Mountains and parts of Canada and Mexico, providing video for broadcast and business television, high-speed Internet access and multimedia services, broadband and data networking.
Geostationary OrbitIntelsat K, Intelsats first Ku-band only satellite, was originally built as Satcom K4 for GE Americom, but was acquired in 1989 and required extensive payload modifications. It is a single spacecraft purchased to meet critical requirements for Ku-band capacity over the Atlantic region, driven primarily by international broadcasters.
