Scientific and technological achievements of Gemini spacecraft

First, it provided enough long-term flight experience for the Apollo program, including physiology, medicine, life and so on.

2. The reliability and service life of long-term operation of temperature, oxygen supply and pressure under manned conditions are verified.

Third, the most important rendezvous and docking of aircraft was completed, which provided strong evidence for the lunar orbit docking scheme of manned landing on the moon.

Four, completed more than two hours of extravehicular activities, and accumulated experience for astronauts in lunar activities.

Fifth, the attitude control, maneuver and orbit change flight of the aircraft are realized. This is the basic task of the Apollo program.

Sixth, the controlled reentry was realized, which improved the landing accuracy and provided greater guarantee for the safety of astronauts.

Seven, the spacecraft is divided into several sections, and only the manned cabin is recovered when re-entering. Apollo spacecraft also adopted this model.

The new fuel cell of Gemini spacecraft has been verified and improved, and successfully applied to Apollo spacecraft.

9. Some problems existing in Gemini spacecraft, such as the reliability of attitude control system, the failure of life-saving system, the heaviness of spacesuit and the difficulty of spacewalking, have been widely absorbed and improved by Apollo program.

Ten, Gemini program also provides astronaut training, space life and other aspects of experience. In addition, Gemini's flight provided direct guidance for the determination of Apollo mission.

Xi。 Long-distance communication with the ground has been developed and verified.

Twelve, the ground control station work to meet the requirements of long-range space flight. In addition, the plan has also made many achievements in earth observation and scientific experiments.
