Its objective was to develop space travel techniques to support Apollo's mission to land astronauts on the Moon. Gemini achieved missions long enough for a trip to the Moon and back, perfected working outside the spacecraft with extra-vehicular activity (EVA), and pioneered the orbital maneuvers necessary to achieve space rendezvous and docking. With these new techniques proven in Gemini, Apollo could pursue its prime mission without doing these fundamental exploratory operations.
The astronaut corps that supported Project Gemini included the "Mercury Seven", "The New Nine", and the 1963 astronaut class. During the program, three astronauts died in air crashes during training, including the prime crew for Gemini 9. This mission was performed by the backup crew, the only time that had happened in NASA's history to that date.
Deeply involved in the investigation of the 1967 Apollo 1 fire, Shea suffered a nervous breakdown as a result of the stress that he suffered. He was removed from his position and left NASA shortly afterwards. From 1968 until 1990 he worked as a senior manager at Raytheon in Lexington, Massachusetts, and thereafter became an adjunct professor of aeronautics and astronautics at MIT. While Shea served as a consultant for NASA on the redesign of the International Space Station in 1993, he was forced to resign from the position due to health issues.
A Ukrainian Zenit-3SL rocket launches the Italian SICRAL 1B military communications satellite from the Sea Launch platform Odyssey, located in the territorial waters of Kiribati, on April 30, 2009. Sea Launch is a unique launch provider that ships rockets and payloads to be launched from a platform placed at the Equator, providing for optimal payload capacity and direct insertion to geostationary orbit (GEO) without the need to change inclination. Sea Launch has conducted 36 launches since 1999, with four failures.
... that astronaut James McDivitt saw a UFO during his first spaceflight?
…that the original videos of the Apollo 11 astronauts walking on the Moon (pictured) were lost after the mission, and were reported to have been found in June 2009?
…that when investigating the Challenger accident, Richard Feynman threatened to remove his name from the report unless it included his personal observations on the reliability of the shuttle?
…that astronauts can't burp in space? A burp would need gravity to separate the liquid from the gas in their stomach.
