During his service with NASA, Armstrong became the first astronaut to set foot on the moon and the first human member to leave footprints on an alien planet on July 2 1, 1969, while his partner buzz aldrin became the second and first person to return to the moon safely and set foot on the earth. They stayed on the surface of the moon for two and a half hours
Armstrong's first space mission was Gemini 8, during which he made the first orbital docking with David Scott. 1In July, 969, Armstrong took a "big step for mankind" when he carried out the second and last space mission Apollo 1 1.
Extended data
When Apollo 1 1 was launched, Armstrong's heart rate reached 109 per minute, and the first stage of the launch was particularly noisy for him-much noisier than the launch of Gemini 8. Compared with Gemini spacecraft, Apollo capsule is slightly larger;
Fortunately, none of them suffered from the space adaptation syndrome encountered by other astronauts. Armstrong was particularly happy. He was carsick when he was a child, and he might get dizzy after turning over a lot.
Armstrong's goal is only to land safely, and there is no special landing site. Because the landing requirements were relatively relaxed, Armstrong did not pay special attention to the specific location of landing on the moon. Three minutes after landing and ignition, he found that the lunar module flew over the designated crater two seconds earlier, which meant that the landing site would deviate from the planned position for several miles. After the landing radar of the lunar module eagle found the target,
There are several mistakes. The first time was error1202; Despite a lot of training before the mission, Armstrong and Aldrin still don't remember the mistakes represented by the code. Armstrong's warning is not so much a special worry as an interference;
His previous career as a test pilot made him understand that as long as the instrument is still working normally and the detector is still acquiring data, there is no need to give up the task. The alarm number 1202 (and later alarm number 120 1) was overflowed by the computer of the lunar module.
An episode of Apollo 1 1 landing on the moon was that there were only a few seconds of fuel left when landing. In fact, Armstrong is not particularly worried about fuel; He used the lunar landing training machine many times in training and landed safely when the fuel was only 15 seconds. He believes that even if the lunar module runs out of fuel at a distance of 15 meters from the ground, there is no problem. Post-mission research shows that the lunar module still has about 50 seconds of fuel.
17: 39 (utc) after the successful landing at 20: 00 on July 20th, Armstrong's first words to the command center and the world were "Houston, this is Jinghai base. The' Eagle' successfully landed. " As a celebration, Aldrin and Armstrong just shook hands, patted each other on the shoulder, and quickly started the mission steps after landing on the moon.
Because of the uncertainty of the possible emergency after landing, the two astronauts in the mission plan need to prepare for rapid takeoff in an emergency immediately after landing.
NASA's official mission plan arranged for two astronauts to take a break before stepping out of the lunar module. Neither of them was very tired, so Armstrong asked if he could advance the moonwalk to evening (Houston time).
Ready to sail, the lunar module depressurized, the hatch opened, and Armstrong slowly walked down the lunar module with a ladder. At 2: 56 am (UTC) on July 2 1, 1969, Armstrong stepped on the moon with his left foot, saying: This is a small step for human beings, but it is a big step for human beings.
