Associated Spacecraft
  • GPS Block 1 American navigation satellite. 11 launches, 1978.02.22 (Navstar 1) to 1985.10.09 (USA 10). GPS Block 1 prototype satellites formed the GPS Demonstration system and were followed by the Block 2 operational system. More...

  • 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 Programs
  • Navstar The Navstar GPS (Global Positioning System) program was a joint service effort directed by the United States Department of Defence. Navstar GPS is a space-based radio-positioning system nominally consisting of a 24-satellite constellation that provides navigation and timing information to military and civilian users worldwide. In addition to the satellites, the system consists of a worldwide satellite control network and GPS receiver units that acquire the satellite's signals and translate them into position information. Originally envisioned as primarily a military system, GPS was found to have a wide variety of civilian applications, many of them never conceived by the original system's designers. More...
