Gemini was originally considered an extension of the Mercury missions, and was originally just designated Mercury Mark II. However, the purpose of the Gemini and follow on Apollo missions was to gain experience in space and test the technologies that would take us to the moon and back, as mandated by President John F. Kennedy.
The first dual mission in space started in 1963, space craft: Vostock 5-6 sent by the USSR
Nasa launched its Gemini mission on November 11, 1966, 3:46:33 p.m
No, Buzz Aldrin did not go on Gemini 9. He was originally scheduled to fly on that mission but was replaced by astronaut Thomas Stafford due to a medical issue. Aldrin later flew on Gemini 12, the final mission of the Gemini program, in November 1966.
Gemini XII was the last Gemini flight, and occurred on November 11-15, 1966. This was the tenth manned Gemini mission.
There were no astronaut fatalities in the Gemini program.Two of the three astronauts who died in the Apollo-1 accident had been in the Gemini program.These were Gus Grissom, and Ed White; Roger Chaffee was also killed in the Apollo-1 accident.
Astronaut James Lovell went with Buzz Aldrin on the Gemini 12 spacecraft.
Armstrong trained about 2 years for his Gemini 8 mission and another 2 years for the Apollo 11 mission. He became an astronaut in September 1962. Basically they trained from the first day they started with NASA.
Here to the question is not at all clear . Which mission are you asking about. The Mercury, the Gemini or the Apollo mission, or are you asking of the Skylab mission or the Space Shuttle mission?
There were multiple Gemini missions into space because there was a lot of work and research that needed to be done.
started in 1961 and ended in 1966
Astronauts Neil Armstrong and David Scott were on board the Gemini 8 mission.
The Gemini mission faced significant challenges during its program, notably the tragic incident of the Apollo 1 fire in January 1967, which resulted in the loss of three astronauts. Although this event directly affected the Apollo program, it also caused delays and heightened scrutiny of NASA's safety protocols, impacting the Gemini missions that were scheduled to support Apollo's objectives. Additionally, there were technical issues during some Gemini flights, such as the Gemini 8 mission, which experienced a critical in-flight emergency when the spacecraft began to spin uncontrollably.
