52 years ago yesterday, a mission was launched that played a critical part in paving the way for the Apollo program that would follow.
NASA’s suborbital Gemini-2 mission launched on July 19, 1965 from the agency’s Kennedy Space Center in Cape Canaveral, Florida. It was the second and last unmanned flight of the Gemini program before humans flew to space and returned to Earth.
The Gemini program took place following the nation’s first man-in-space program, Mercury, and before the program that sent humans to the moon, Apollo. After Gemini-2, the 10 manned Gemini missions each carried two astronauts into space.
During Gemini, equipment and mission procedures were tested in Earth orbit. Astronauts and ground crews were trained for Apollo missions that would follow. Experiments in space and spacewalks were conducted.
The Gemini-2 test mission successfully demonstrated the adequacy of the spacecraft reentry module’s heat protection during a maximum heating reentry, the spacecraft’s structural integrity, and the performance of spacecraft systems. The mission lasted for 18 minutes and 16 seconds.
Gemini-2 launched on a modified Titan II rocket. Originally dismantled twice to be protected against hurricanes, the launch vehicle was erected on the launch pad in September 1964 ahead of its launch.
Between 1962 and 1966, Gemini both defined and tested the systems needed for NASA to go to the moon. The program objectives were to test the ability of humans to fly in space for up to two weeks, understand how spacecraft could rendezvous and dock while in orbit around the Earth and moon, perfect reentry and landing methods, and gain a better understanding of how astronauts are affected by longer space flights.
