The trio on a business trip to space will return to Earth in April, what are your expectations?

The expectation is: I hope that the three astronauts can return safely, and at the same time, I hope to add more analytical data to China's aerospace industry and take our aerospace industry to a higher level.

To review, the three people on a business trip to space traveled to space at 9:22 on June 17, 2021, Beijing time. Since 2021, my country's manned space project has successfully implemented 5 missions in the key technology verification phase of the space station. Currently, the core module assembly is operating stably in orbit, and the Shenzhou 13 astronaut crew is in good condition and is scheduled to return in April this year. On the ground, key technologies for space station construction have been fully verified, and preparations for follow-up missions have been solidly advanced.

What new achievements has China made in manned spaceflight?

In five months, astronauts carried out key technology tests for the assembly and construction of the space station. During the mission, the feasibility and effectiveness of the robotic arm-assisted cabin transposition were tested through experiments such as manual remote operation

; the space station cabin transposition technology and Robotic arm large load control technology. For the first time in orbit, astronauts used hand-controlled remote control equipment to control a cargo spacecraft to rendezvous and dock with the space station. The functional performance of the manual remote control system of the space station and visiting aircraft has been preliminarily verified. It has accumulated valuable experience for the subsequent orbit assembly and construction of the space station.

What to do in the preparation stage for return

As about 180 days of space life comes to an end, the astronauts have begun preparing to "go home" in the past two days. Zhong Weiwei, associate researcher at the Aerospace Medical Engineering General Office of the China Astronaut Training Center, said in a recent interview with the media: "There is a large amount of materials that need to be sorted out before departure, including the packages and various products on Tianzhou-3. Shenzhou 10 will follow It may take more than a month to come back on the 4th, so we need to put all these products and equipment in place in advance. In addition, we need to bring back important samples, which also need to be planned in advance starting from next week. Carry out this part of the work.”

A new era of China’s space station construction is coming

In general, our country’s space station is currently proceeding in an orderly manner as planned. The space arms race has become a key battle for various countries to compete for scientific and technological hard power. It is the highest essence of modern science and technology. Its construction and operation are a test of a country's comprehensive scientific and technological capabilities. Among these high-tech technologies, space docking It is undoubtedly one of the most critical and challenging core technologies.

Shenzhou 13 is the final battle in the key technology verification phase of the space station. I believe that in six months, the verification tasks carried by Shenzhou 13 that we are concerned about will be answered. In the next time, according to the plan, our country will launch these two experimental modules one after another in 2022, and rendezvous and dock with the Tiangong Space Station to form a complete body. At the same time, the manned spaceflight project will also enter normalization, and we will use it in more ways Get to know the mysterious space.

In addition, after the Shenzhou 13 mission, our country will successively launch Tianzhou 4, Shenzhou 14, Wentian Experimental Module, Mengtian Experimental Module, Tianzhou 5, and Shenzhou 10. Missions such as the 5th will not only complete the assembly and construction of the Chinese space station, but also allow the space station to enter the formal operation stage.
