Who is the second man to land on the moon?

Buzz aldrin? (English: Buzz Aldrin,193065438+1October 20th-).

He used to be an American pilot and an astronaut of NASA. He is famous for being the second man to set foot on the moon (after Unul Armstrong) and the first man to return to Earth after landing on other planets in Apollo 1 1.

Aldrin was selected as the third astronaut by NASA. During the planning of Gemini project, his earnest attitude and education proved invaluable, even if he didn't get the task. The main members of Gemini 9A (Charles Bassett and Eliot Hirsch) were killed in the accident, which gave Aldrin a chance to become a substitute member.

The main task of Gemini 9A is to rendezvous and dock the main spacecraft with a target spacecraft in Earth orbit, but when the docking fails, Aldrin temporarily prepares to rendezvous and dock the main spacecraft with a coordinate point.

Aldrin is the pilot of Gemini 12. Gemini 12 is the last mission in the Gemini program and the last opportunity to test the method of extravehicular activity before the Apollo program.

Aldrin invented some revolutionary skills during training Gemini 12, including neutral-underwater training; These technologies are still in use today.

Aldrin created a time record of extravehicular activities in Gemini 12 mission, which proved that astronauts could work long hours in the spacecraft and took their first selfie in space because of the need of the mission.

After stopping the space mission, Aldrin returned to the Air Force as a manager, but his personal life began to have problems. His autobiography "Back to Earth" reveals the story of depression and alcoholism after he left NASA. After leaving NASA, Aldrin continued to promote space exploration.

1985, Aldrin put forward the theory of Mars circular orbit, which is called "Aldrin circular orbit".

1988, Aldrin changed its name to Buzz. Buzz Lightyear, the character of Toy Story, was inspired by Aldrin himself. Later, he was invited to attend the premiere of Toy Story in June 5438+0995165438+10/0.
