Associated Programs
  • STS The Space Transportation System (Space Shuttle) was conceived originally as a completely reusable system that would provide cheap, routine access to space and replace all American and civilian military launch vehicles. Crippled by technological overreach, political compromise, and budget limitations, it instead ended up costing more than the expendable rockets it was to have replaced. STS sucked the money out of all other NASA projects for half a century. The military abandoned its use after the Challenger shuttle explosion in the 1980's. 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...
