One of the happiest things about Downing in 1969 was that he met a new friend, this person is the American astronaut Neil Armstrong, who has left a strong mark in the history of human development, it is a little unbelievable that he will be a good friend of Jimmy, a playboy, which makes Downing very emotional, it seems that the theory of six people (you and anyone you don't know, you only need to pass through six people in the middle, you can get in touch) is really some truth, Anyway, Tang Ning couldn't believe that the two of them would know each other beforehand.

This time was actually Armstrong's period of rest and adjustment, since the successful moon landing, he was scheduled to travel a lot of lectures and business activities, because of these activities that he was not used to and did not get enough rest and adjustment after returning from the moon landing, so he is now in a somewhat unwell physical and mental state, so he is now in a limited period of rest. Downing was fortunate enough to have dinner and chat with the legendary astronaut with Jimmy.

In fact, Armstrong was originally only the 11th of the Apollo program, but when the project was first started, Apollo 1 was destroyed due to a fire. Gleason, Edward? White and Roger? Chaffee was all sacrificed.

To familiarize the astronauts with the operation of the lunar module, Bell Aerosystems produced two Lunar Landing Research Vehicles, which were later converted into Lunar Landing Training Vehicles. The two machines are capable of simulating one-sixth of the Earth's gravity on the lunar surface, allowing astronauts to adapt to the operation of the lunar module in advance. On May 6, 1968, while training, Armstrong suddenly failed at an altitude of about 30 meters. Later studies showed that Armstrong escaped 0.5 seconds late. His parachute did not have enough time to fully open. Armstrong was not seriously injured, but only bit his tongue. Although he almost lost his life, Armstrong still believes that the moon landing training plane played a role in simulating the moon landing.

Armstrong's heart rate reached 109 beats per minute when Apollo 11 was launched, and the first phase of the launch was particularly noisy for him – much louder than the launch of Gemini 8. Compared to the Gemini spacecraft, the Apollo capsule is slightly larger; But lucky. None of the three suffered from the space adaptation syndrome that other astronauts had encountered. Armstrong was particularly pleased, having suffered from motion sickness as a child and the possibility of dizziness after a lot of flipping maneuvers.

Armstrong's aim was simply to land safely, without a particular landing spot. Due to the relatively relaxed landing requirements, Armstrong was not particularly concerned about the exact location of the moon landing. Three minutes after the ignition landed, he discovered that the lunar module had flown over the designated crater two seconds ahead of schedule, meaning that the lunar landing site would be several miles away from the planned location. After the landing radar of the lunar module "Eagle" found the target, there were several errors. The first time was error 1202; Despite a lot of training before the mission, Armstrong and Aldrin still couldn't remember the mistakes that the code represented. The loud sirens for Armstrong were more of a distraction than a particular concern to him; His previous career as a test pilot had taught him that as long as the instrument was still working. The probe is still getting data, so there is no need to abandon the mission. Alert 1202 (and later Alert 1201) was a calculated overflow by the lunar module's computer.

One of the episodes of the Apollo 11 moon landing was that there were only a few seconds of fuel left when it landed. Actually, Armstrong wasn't particularly worried about fuel; He used the moon training plane several times during his training to land safely with less than 15 seconds of fuel left. He believes that even when the lunar module runs out of fuel at 15 meters above the ground, there will be no problem. Post-mission studies showed that the lunar module had about 50 seconds of fuel left.

After successfully landing at 20:17:39 UTC on July 20, 1969, Armstrong's first words to the command center and the world at large were 'Houston, this is the Silent Sea base.' The Eagle landed successfully. In celebration, Aldrin and Armstrong simply shook hands, patted each other on the shoulder, and quickly began the steps of the mission after the moon landing. Due to the uncertainty of possible contingencies after landing, the two astronauts in the mission plan needed to be prepared for rapid take-off in case of emergency immediately after landing.

NASA's official mission plan is to have two astronauts rest for a while before stepping out of the lunar module. Neither of them was very tired. Armstrong then asked if he could bring the moon walk forward to the evening (of Houston time). Ready to stop, the lunar module was depressurized. The hatch opened, and Armstrong slowly descended the lunar module with a ladder. At 2:56 a.m. (UTC) on July 21, 1969, Armstrong stepped on the moon with his left foot and said:

It's a small step for a person, but it's a giant leap for humanity.

(Thatsonesmallstepfor(a)man,onegiantleapformankind.)

The simple but timeless phrase of 'one big step' was just one of the many things that Armstrong had on his mind after landing, and it wasn't something he had thought about in advance. Armstrong knew exactly what he needed to say after taking the first step. So mentioning 'one step' seems like a good place to start. There is a hypothesis that he consciously borrowed a phrase from J.R.R. Tolkien's The Adventures of the Hobbit ('Not a big step for him, but a step in the dark.') Or a memo from an official at NASA. Armstrong denied either claim.

Fifteen minutes after Armstrong took his first step, Aldrin also set foot on the moon, becoming the second human member to set foot on the moon. They began to test the feasibility of human walking on the moon. At first, they also lifted the cover of the lunar landing commemorative plaque on the ladder of the lunar module. And planted an American flag on the ground. The flag has a wire at the top that allows the flag to be unfurled even when there is no wind. Since the wire has not been straightened, the flag has been folded before, so it looks as if the wind is blowing. There was a debate on the ground about whether the flag should be planted, but Armstrong didn't think it was a big deal. Dick? Slayton had told Armstrong that they would receive a special communication, but did not say that the signal would be on the other end of the line, President Richard? Nixon.

After installing the early Apollo science experiment kit, Armstrong walked 60 meters away from the lunar module, which was later named the East Crater. This is the farthest distance that the two can travel on the surface of the moon. Armstrong's last mission was to place a memorial plaque on the surface of the moon in memory of the Soviet cosmonaut Yuri, who died for the sake of astronautics. Gagarin, Vladimir? Komarov and the three astronauts of Apollo 1, Chaffee, Gleason and White.
