50 years ago, the United States had already made a plan to fail in the moon landing. How was the plan arranged? ?

In 1969, American astronauts Neil Armstrong and Buzz Aldrin became the first and second people to land on the moon in human history. The then US President Richard Nixon immediately met with them He started the conversation and said: "Because of everything you have done, heaven has become a part of the human world."

But do you know? In fact, both the U.S. government and the astronauts were prepared to fail in the moon landing. Preparations for the failure of the moon landing

Although the successful U.S. moon landing was very encouraging at the time, according to the parties involved afterwards, they had prepared a series of procedures in case the moon landing failed. The two The fact that astronauts cannot return.

It is understood that once the moon landing fails and the astronauts die, the President of the United States will first call the widows of the astronauts. Then, the President of the United States will prepare a speech that will be broadcast on national television.

In the speech, there is a description like this: Their sacrifices have brought hope to mankind, because they sacrificed for the most noble goal of mankind: exploring and understanding the truth.

Immediately afterwards, the priest will start the sea burial process and deliver the souls of the two astronauts to the depths of the ocean so that their souls can rest in peace.

This plan was called the "Moon Disaster Plan", but fortunately, humans successfully landed on the moon. After the successful landing on the moon, the two astronauts successfully returned to orbit and joined another astronaut. rendezvous and then return to Earth.

Although this lunar disaster plan was not used, it was still announced through the media 30 years after the incident. Safire, who participated in the formulation of the lunar disaster plan at the time, said : Although the two astronauts successfully landed on the moon at that time, driving the lunar module back to orbit to rendezvous with the command module was one of the most dangerous aspects of the entire Apollo 11 mission. Any accident may lead to disaster, so even if At that time, the two astronauts successfully landed on the moon, but scientists were still worried about their next fate.

At the same time, Safire also said that once an astronaut encounters an accident during the moon landing, NASA will cut off communication with the moon landing astronauts, and they will have to be abandoned on the moon. , either starve to death or commit suicide.

It’s not that humans don’t want to rescue them, but that the lunar exploration program is inherently difficult, and the environment in space is very harsh, making it impossible for humans to carry out effective rescue methods.

In fact, not only the U.S. government was prepared to fail in the moon landing, but even these three astronauts were prepared to fail in the moon landing (two astronauts landed on the moon, and one in response in the command module).

Because the space moon landing project was too dangerous, no insurance company was willing to insure them. However, for the sake of their families, these three astronauts signed a lot of blank envelopes before landing on the moon, and then Have them go to the post office to get it stamped on the day of the moon landing.

In this way, even if you encounter an accident during the moon landing, your family members can still earn a lot of income by signing these envelopes.

But fortunately, nothing they worried about happened, and they returned to Earth safely after completing their space mission. Failed Moon Landing

Although Apollo 11 was a success, Apollo 13 was not so lucky.

Apollo 13 was the third manned mission to the moon. However, about 55 hours after launch, the oxygen tank in the service module exploded. The spacecraft was severely damaged and a large amount of oxygen was lost. leaked into space.

They immediately reported the situation to the ground command center and said the famous sentence: Houston, we are in trouble.

After receiving the information, Houston immediately collected data, analyzed the situation, then simulated various situations and formulated various plans. After a long emergency discussion, Houston decided to cut off power to the command module Odyssey and reserve power until it enters the Earth's atmosphere and then restarts. That's because the Odyssey is the only one that can withstand the high temperatures generated when the spacecraft rubs against the atmosphere.

In addition, they will also use the lunar module Aquarius as a rescue capsule, relying on it to lead the astronauts back to Earth. At that time, relevant personnel in Houston quickly gathered together to discuss various situations, listing 85 different situations in one go, and formulating the optimal solution for each situation.

This work is very physically and mentally demanding, but none of them feel tired. Later, they recalled that it felt like they had worked for 10 hours during that period, but later they learned that they had worked without sleep for three days.

Relying on the efficient and powerful solutions of the ground command center, coupled with the astronauts' calmness and rich emergency response experience, they finally returned to Earth safely. Although the moon landing program failed, the astronauts survived. Summary

Whether it is landing on the moon or performing other space missions, astronauts will face certain dangers. If there is a possibility of rescue, scientists and governments on earth will do whatever it takes to rescue them. . But if through various scientific calculations, the probability of successful rescue is 0, then scientists will have no choice but to give up the rescue.
