What are the performance characteristics of American Gemini spacecraft?

Compared with Mercury spacecraft, Gemini spacecraft has been greatly improved, and the flight of two astronauts has been realized. The design of the spacecraft is mainly manual control, making it the most powerful manned spacecraft in the United States so far. In the Gemini flight, astronauts really became the pilots and controllers of the spacecraft, and besides the experiments of people adapting to the space environment, they also carried out some technical experiments and achieved some new breakthroughs in space technology, mainly including the astronaut's extravehicular activity technology, the rendezvous/docking technology of the spacecraft, and the automatic flight control technology using computers.

Gemini Plan * * * carried out 10 manned flights with a total flight time of 97 1 hour and 48 minutes.

From 65438 to 0958, NASA headquarters and space mission team began to consider the goals and tasks of the American manned space program after Mercury manned space program. The space task force headed by Gilrose and Fajit is particularly concerned about this. They believe that this plan should achieve two major goals on the basis of project mercury's completed tasks: the flight time of manned orbit is greatly extended, reaching more than 1 week; Realize spacecraft in-orbit maneuver, rendezvous and docking.

When the United States made the Apollo moon landing plan in 196 1, the task of this plan was more clear, that is, to explore and test new technologies to complete the moon landing mission, of which two aspects are the most important: first, to extend the manned flight time to two weeks to fully study the adaptability of people living and working in space; The second is to complete the rendezvous and docking of two spacecraft in orbital maneuver. These two tasks will be completed during the moon landing. In this way, the Gemini program became an auxiliary project of the Apollo program.

Gemini spacecraft was launched for the first time in March 1965. By June of 1966, 1 1, Gemini spacecraft had carried out nine manned flights and successfully completed its scheduled mission. In addition, the Gemini program has also made a lot of achievements in earth observation and space science experiments: astronauts conducted 52 experiments, of which 27 were new technology experiments, 8 were medical experiments and 17 were scientific experiments. Gemini spacecraft also took 1400 color photos of different heights of the earth.
