John Glenn 13, "Friendship 7", and had the name hand-painted on the side like the one on his F-86 had been. Glenn and Carpenter completed their training for the mission in January 1962, but postponement of the launch allowed them to continue rehearsing. Glenn spent 25 hours and 25 minutes in the spacecraft performing hangar and altitude tests, and 59 hours and 45 minutes in the simulator. He flew 70 simulated missions and reacted to 189 simulated system failures. After a long series of delays, "Friendship 7" lifted off from Cape Canaveral Air Force Station on February 20, 1962.

Galileo (spacecraft) 1970s the first flybys of Jupiter were achieved by "Pioneer 10" and "Pioneer 11", and before the decade was out it was also visited by the more advanced "Voyager 1" and "Voyager 2" spacecraft. Work on the spacecraft began at Jet Propulsion Laboratory in 1977, while the "Voyager 1" and "2" missions were still being prepared for launch. Early plans called for a launch on on what was then codenamed STS-23 in January 1982, but delays in the development of the Space Shuttle allowed more time for development of the probe. As the shuttle program got underway, "Galileo" was scheduled
