Looking back, the trio went to space on business at 9: 22 on June 17, Beijing time. Since 20021,China's manned spaceflight project has successfully carried out five missions in the key technology verification stage of the space station. At present, the core module assembly runs stably in orbit, and the Shenzhou-13 astronaut is in good condition. It is planned to return to the ground in April this year. The key technology of space station construction has been fully verified, and the preparation for the follow-up mission has been solidly advanced.
What new achievements has China made in manned space flight?
In five months, astronauts conducted key technical tests on the assembly and construction of the space station. During the task, the mechanical arm is used to assist module indexing.
Experiments such as manual control and remote operation; The feasibility and effectiveness of mechanical arm assisted cockpit transposition are verified. The transposition technology of space station cabin and the heavy load control technology of manipulator are verified. For the first time, astronauts used hand-controlled teleoperation equipment in orbit to control the rendezvous and docking of cargo spacecraft and space station. The functional performance of manual teleoperation system of space station and visiting aircraft was preliminarily verified. It has accumulated valuable experience for the subsequent on-orbit assembly and construction of the space station.
What should I do when I return to the preparation stage?
With about 180 days of space life coming to an end, astronauts have begun to prepare for "going home" these two days. Zhong Weiwei, an associate researcher in the General Office of Aerospace Medical Engineering of China Astronaut Training Center, said in an interview with the media a few days ago: "There are a lot of materials to be sorted out before departure, including those packages and various products on Tianzhou-3. Later, it may take more than a month for Shenzhou XIV to come up again, so all these products and equipment should be put in place in advance. In addition, we need to bring back important samples, which also needs to be planned in advance. Starting next week, we should focus on this part of the work. "
A new era of China's space station construction is coming.
Generally speaking, China's space station is proceeding in an orderly way as planned. The space arms race has become a key battle for the hard power of science and technology, and it is the highest essence of modern science and technology. Its construction and operation is a test of 1 national comprehensive scientific and technological capabilities, and among these high-tech technologies, space docking is undoubtedly one of the most critical and challenging core technologies.
Shenzhou XIII is the final battle of the key technology verification stage of the space station. I believe that after half a year, the verification mission carried by Shenzhou XIII that we care about will have an answer. In the next time, according to the plan, China will launch these two experimental modules one after another in 2022, and rendezvous and dock with Tiangong Space Station to form a complete body. At the same time, the manned spaceflight project will also be normalized, and we will learn more about the mysterious space.
In addition, after the Shenzhou XIII mission, China will also launch Shenzhou IV, Shenzhou XIV, Inquisition Module, Dream Module, Shenzhou 5, Shenzhou XV and other missions, which will not only complete the assembly and construction of China's space station, but also make the space station enter the formal operation stage.
