The Moon has a gravitational and gravitational difference with the Earth, how did the astronauts who

In order to better understand the situation on the moon, many astronauts went to the moon to survey some meteorological features and environmental changes at that timeSo the moon has a gravitational and gravitational difference with the earth, how did the astronauts who landed on the moon return to the earth? Generally, when landing on the moon, scientists will deliberately develop some lunar modules with their own launch systems, and then astronauts only need to take the lunar module to meet with the orbit and command module near the moon, so that the lunar module will be left in space, and the astronauts can successfully return to Earth in the command module.

When astronauts went to the moon to investigate, there were no other signs of life on the surface of the moon, and humans were not capable of making huge space launchers, so they could only rely on the landing module to learn some relevant information about the moon. Moreover, there is a relatively large difference in gravity and gravity between the moon and the earth, if the weight of the object on the earth reaches several tons, it can be easily lifted on the moon, and the landing module can easily float around on the moon.

According to scientists' research, the distance between the earth and the moon is about 380,000 kilometers, so if you want to get rid of the binding force of the earth's gravity, you need to be faster. Because the speed is relatively fast, the spacecraft needs to consume a lot of fuel in the process of launch, and there is a special gravitational environment on the surface of the moon, so it is relatively easy.

Of course, scientists can design a lunar module that allows astronauts to go to space to set up a command module that allows astronauts to successfully return to the earth, and when the astronauts take the lunar module to the orbit near the moon to meet with the command module, they will leave the lunar module in space, and the astronauts can return to the earth by taking the command module that originally rendezvous, and at this time, there is no need to accelerate to the second cosmic speed to successfully reach the earth.

After the astronauts complete their lunar walk, they will return to the lunar module, which has a return capsule on the upper stage, which is very light in weight and has fuel and a single engine, and then will be pushed into lunar orbit to dock with the command module, and can return directly to Earth.

There is indeed a gravitational gap between the moon and the earth, and if the astronauts who land on the moon want to return to the earth, scientists on the earth will send a docking device to dock with the astronauts' spacecraft and send the astronauts back to earth safely.

Rely on spacesuits. Astronauts' clothes rely on the power of technology to achieve only a round trip between the Earth and the Moon, reducing the difference in gravity and gravity.

Summary. Hello, dear, it takes 4 more days for astronauts to return to Earth from the Moon, and it takes about 4 hours from the time the spacecraft receives the command to disengage from the International Space Station, and it takes about 4 hours to land safely on Earth, which uses fast return technology.

Hello Gao Sui, dear, it takes 4 more days for the astronauts to return to Earth from the moon, and it takes about 4 hours to land safely on Earth from the time the spacecraft receives the order to break away from the International Space Rental Station.

There are many factors that astronauts need to consider when returning to Earth, such as weather, spacecraft speed, distance from the ground, etc. Therefore, the time for astronauts to return to Earth should be determined according to the implementation situation.

Normally, the spacecraft must go through four stages: deorbit, transition, re-entry and landing.

The time it took for Armstrong to return to Earth on the moon in 1969.

A total of 4 days to carry the transport (to the moon rubber turn to the moon back to the moon), launched away from the earth for.

How long does it take for the lunar module to leave the moon and return to the Earth's surface, that is, to return to Earth after the end of the exploration?

Pro, it takes 8 hours.

Is the statement "60 hours from the moon back to Earth" correct, and did it take Armstrong 8 hours to return to Earth that year?

Dear, there are currently no 60 hours from the moon back to Earth", and there is no such record.

So is there official data to indicate or provide that it will return to Earth in about 8 hours? Or, given the circumstances at the time, is it credible to return to Earth in 8 hours.

Dear, it was 4 days to return, and now it is 8 hours, for example, the 14th is 8 hours.

I'm sorry, I mean in 1969 when they finished the exploration, from boarding the re-entry capsule and starting to return, to returning to the surface of the earth, at this stage, how much did they lose when they used the envy stool, was it 8 hours, or the so-called 60 hours, or there are other theories.

The time it took for Armstrong to return to Earth after the 1969 moon landing was 8 hours.

Please ask where the data comes from, and whether it is credible.

On July 16, 1969, Armstrong with Aldrin Jr., MCollins flew to the moon together on the Apollo 11 spacecraft. Four days later, at 4:18 p.m. EDT, he manually piloted the Eagle's lunar module to land on a flat ground near the southwestern edge of the Tranquil Sea.

At 10:56 p.m. EDT on July 20, Armstrong stepped down from the Eagle's lunar module and stepped onto the dusty surface of the moon, saying that "this is a small step for one person, but a huge leap for all of humanity." Arms left the lunar module with Chun Tantron and Aldrin Jr., spent more than 2 hours setting up scientific instruments, collecting lunar surface specimens, and staying for 21 hours and 36 minutes before taking off again, rendezvous with Collins, and began the voyage back to Earth.

Speaking of this issue, we have to talk about spaceships, only spaceships can send people into space, it is impossible for rockets to send people into space, rockets are just a starting device.

A spaceship, also called a spaceship, is a type of transporting astronauts. Cargo arriving in space is safer than returning to a single-use spacecraft, typically by two to three astronauts.

A spaceship is very similar to a space shuttle, but not the same structure and function. The biggest difference between the structure of a spaceship and a space shuttle is that there are no wings, and the spacecraft are lifted vertically with rockets and landed at fixed points by parachute. The space shuttle also uses a rocket to lift vertically into the sky and lands horizontally like an airplane when it returns to the atmosphere.

Spaceships can only be used once, space shuttles can be reused many times, and spaceships are much smaller than space shuttles.

Spacecraft can be divided into orbital compartments, return capsules, service compartments. The focus here is on the return capsule.

We all know that the return capsule from the moon, for example, is the place where astronauts made it. Before the spacecraft returned to the ground, the orbital module and the service module were separated from the re-entry module, respectively, and burned out in the atmospheric process. The astronauts returned to the ground in a return capsule.

After receiving the command from the ground command center to decide to return home, the astronauts will adjust the flight parameters of the spacecraft and activate the braking rocket in the opposite direction of the spacecraft to reduce the flight speed of the spacecraft. In this way, the spacecraft will leave its original flight trajectory and gradually transition to the orbit into the atmosphere. The "re-entry angle" of the spacecraft to return to the ground, that is, the angle between the direction of flight and the local water level when entering the atmosphere, is the key to whether the spacecraft can safely return to the ground.

In general, this wing angle should not exceed 3 °. If the re-entry angle is too large, the spacecraft will fall to the ground like a meteor and burn up; If the re-entry angle is too small, the spacecraft will fly back into space and will not be able to return to the ground.

The re-entry capsule must pass through the black barrier. Because the gravitational acceleration of the spacecraft causes the temperature to rise sharply, which is beyond people's imagination and is very terrifying. The reason why it is called the black barrier area.

Summary: The spacecraft carries its own fuel, and it is actually easier to return to the ground on the moon than from the ground to the moon, because the moon has no atmosphere, and the gravitational pull of the moon is smaller than that of the earth, so the spacecraft ignites the fuel and departs from the original flight orbit.

It is impossible to survive, and the hope is very slim, because the food prepared by the astronauts when they land on the moon is limited, so it is difficult for the astronauts to survive.

No, you cannot. Because there is no oxygen and some food on the moon, human survival is inseparable from these things, so it is impossible to survive.

Probably not, because there is nothing on the moon that is necessary for survival, and it is very dangerous in this place.
