How long will it take for Shenzhou 12 to return to Earth

It will take about an hour for Shenzhou-12 to return to Earth. After receiving the order to separate from the space station, Shenzhou-12 did not immediately carry out the return procedure, because the astronauts had some work to do. It is necessary to sort out the data recorded in the three months of flying, to count and sort out the materials of the space station, and to carry out a thorough cleaning of the space station.

Prepare for the docking of Shenzhou-13 to the space station later. Therefore, it was used for about an hour.

Manned spacecraft: Manned spacecraft is generally composed of crew, return cockpit, orbital module, service module, docking module and emergency rescue device, and the lunar spacecraft also has a lunar module. The return cockpit is the core segment of the manned spacecraft and the control center of the entire spacecraft.

The re-entry module, like all other modules, is subject not only to the stresses and environmental conditions of the take-off, ascent and orbital phases, but also to deceleration, overload and aerodynamic heating during the re-entry and return phases to the surface. The orbital module is the workplace of astronauts in orbit, which houses various experimental instruments and equipment. The service module is usually equipped with equipment such as propulsion system, power supply and air source, which plays a role in service support for the spacecraft.

A docking module is a module used to dock with a space station or other spacecraft.

The astronauts of Shenzhou-12 were launched on June 17, 2021, and the space station mission lasted three months. Therefore, the astronauts should return to Earth around mid-September. And specifically:

It lasted three months and laid the foundation for the future

As we all know, our country has finally established a space station outside the earth after difficulties, and the space station that has been the envy of people for several generations in the past is naturally not repeated, so for our astronautsThe mission entered the space station to debug and lay the foundation for the use of the space station for the next 20 years.

In other words, it's not too much to stay in orbit on the space station for another three monthsYou must know that the astronauts finally went to the space station for the last time, and their tasks can not be complicated and detailed! At the same time, the integration of air and space, and the coordination of land and air integration can not be optimized as much as possible?

2. Return to the National Day, the time is undecided

Therefore, if there are no accidents in the original plan, they must return according to the instructions three months after entering the space station, knowing that the Chinese space station is already in operationAt that time, this was only a key step in the development of the space station, and various problems such as the docking of future supply spacecraft and the rotation of astronauts still pose challenges to Chinese astronauts in the future.

Therefore, as a soldier, astronauts must complete the task of "laying the foundation" for the space station in a limited space time, otherwise their lives will face huge risks, and the operation of the space station will also be affected by far-reaching hidden dangers.

In summary, if the space station operation is to be carried out, it must be completed within three months. In other words,It is on the eve of the National Day, in mid-September, that this group of brave and courageous people will leave the space stationAfter the relevant construction for the future space station, take the return spacecraft, enter the Earth's orbit and return to Earth. And this seems to be a few words, but the danger behind it can't be **!

So the exact time of their return can only be tentative.

It returned to Earth in mid-September, and the successful launch of Shenzhou-12 also shows that China's aerospace science and technology level is developing very rapidly, and China's comprehensive national strength has been enhanced.

The Shenzhou-12 astronauts successfully completed the second exit and returned to Earth in mid-September.

At present, many tasks have been completed one after another, and it is expected that Shenzhou 12 will return in mid-September, and the astronauts on it are about to go home.

I sincerely wish the astronauts a safe return and celebrate the Mid-Autumn Festival and the National Day with the people of the whole country.

The author's level is not graduated from junior high school, and there are too many mistakes in sentences.

It was originally scheduled for mid-September, and the specific time is hard to say, depending on whether the work above is done or not, and how much supply is left to determine the specific time.

The latest news, the General Mission Command of the Space Station Engineering Phase of the Manned Space Project has decided that the Shenzhou-12 spacecraft will return to Earth on September 17.

The Shenzhou-12 manned spacecraft completed the orbiting and radial rendezvous tests

According to the China Manned Space Engineering Office, after the evacuation of the Shenzhou-12 manned spacecraft, at 13:38 Beijing time on September 16, 2021, it completed the orbiting and radial rendezvous test with the space station assembly, successfully verifying the radial rendezvous technology and laying an important technical foundation for the subsequent manned mission. Subsequently, the Shenzhou-12 manned spacecraft will re-enter and return as planned, and astronauts Nie Haisheng, Liu Boming, and Tang Hongbo will soon set off to return to the embrace of the motherland.

September 17, 2021The three astronauts of the Shenzhou-12 manned spacecraft, Nie Haisheng, Liu Boming and Tang Hongbo, successfully returned to Earth, and the Shenzhou-12 manned mission was a complete success!

On September 17, Beijing time, the return capsule of the Shenzhou-12 manned spacecraft landed safely in the predetermined area of the Dongfeng landing site, and astronauts Nie Haisheng, Liu Boming, and Tang Hongbo arrived safely in Beijing. The first manned mission in the construction phase of China's space station was a complete success.

On June 17, 2021, the Long March-2F Yao-12 carrier rocket carrying the Shenzhou-12 manned spacecraft was launched from the Jiuquan Satellite Launch Center, sending Nie Haisheng, Liu Boming and Tang Hongbo to Tiangong, China's own space station, and the three of them also started a three-month space business trip.

On July 4, the three astronauts performed the first time to go out of the capsule, and everything went very smoothly. On August 20, they carried out another out-of-cabin mission, and the process was even faster than the first time. All this indicates that China's astronauts have the world's top quality, and China's aerospace technology has also reached the world's top level.

In the blink of an eye, 3 months are about to pass, and the 3 astronauts are about to return to Earth. According to the plan, in mid-to-late September, they will return to the ground on the Shenzhou-12 spacecraft to end this space trip.

The Shenzhou-12 manned spacecraft returns to the earth, and the way to ensure the return time and place is the guidance of the ground command base and the intelligent setting of the return capsule. The trajectory of the Shenzhou-12 manned spacecraft returning to the earth has been designed, and the ground command base will give the return capsule certain guidance, and then the return capsule has a set route and intelligent adjustment and navigation, and finally achieves a purpose that can ensure the return time and place. It's clear they've done it.

At 13:34 on September 17, 2021, the return capsule of the Shenzhou 12 manned spacecraft successfully landed in the predetermined area of the Dongfeng landing site. Let the Shenzhou Sanlu No. 10 spacecraft complete the landing task at a fixed time.

The Shenzhou 12 return capsule has changed from a fixed time and fixed point return to a dynamic adaptive return, because the dynamic adaptive return can better ensure the safety of the Shenzhou 12 return capsule. The aiming location was determined before the return of the Shenzhou 12 return capsule, and then a series of standard processes were initiated to dynamically adjust the trajectory and implement precise return control. In the end, the exact time was completed, the landing was within the accurate range, and the Shenzhou 12 successfully landed.

The three astronauts on board Shenzhou-12 worked in China's space station for 90 days, which broke the record for the longest time a Chinese astronaut stayed in space. Astronauts need to bear the pressure of one more day every day in space, so we must do it when astronauts return, so that they can return to the embrace of the earth on time.

Before returning, the trajectory of the Yiye Zhixian series is all through the ** fierce one, so that they can return safely, there will be no accidents, everything has been calculated.

The Shenzhou-12 manned spacecraft is currently preparing to return, and scientists have set the parameters for the state to hold the sock and return hidden. The spacecraft will perform operations in a specific orbit.

Then calculations should be made, and the movements of Shenzhou 12 should be closely followed.
