ATS-2
Credit: NASA
American communications technology satellite. One launch, 1967.04.06, ATS 2. ATS-2 was placed into an undesirable orbit due to a launch vehicle failure.

Atmospheric torques in this orbit overcame the satellite's gravity gradient stabilization system, and caused a slow tumble. Although the satellite remained functional, the satellite was deactivated after six months due to the limited amount of data that could be received from the spacecraft. Spacecraft: Aluminum structure, drum solar array providing 125W BOL, 2 6 Ah NiCd batteries, gravity gradient stabilization. Payload: Meteorological experiments, C-band communications package

AKA: Applications Technology Satellite.
Gross mass: 370 kg (810 lb).
Height: 1.80 m (5.90 ft).
First Launch: 1967.04.06.
Number: 1 .

  • Atlas The Atlas rocket, originally developed as America's first ICBM, was the basis for most early American space exploration and was that country's most successful medium-lift commercial launch vehicle. It launched America's first astronaut into orbit; the first generations of spy satellites; the first lunar orbiters and landers; the first probes to Venus, Mars, Mercury, Jupiter, and Saturn; and was America's most successful commercial launcher of communications satellites. Its innovative stage-and-a-half and 'balloon tank' design provided the best dry-mass fraction of any launch vehicle ever built. It was retired in 2004 after 576 launches in a 47-year career. 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...
  • Cape Canaveral LC12 Atlas launch complex. The complex was built for the Atlas ballistic missile program. Launch sites 11 to 14 were accepted between August 1957 and mid-April 1958. Complex 12 supported its first Atlas launch on 10 January 1958, and it supported nine Ranger missions and four Mariner missions between 12 August 1961 and 15 June 1967. Complexes 11, 12 and 14 were deactivated in 1967, and Complex 13 was deactivated in April 1978. More...
