At the end of the six-month space flight journey, the return capsule of the Shenzhou 17 manned spacecraft took three astronauts to land safely at the Dongfeng landing site, Tang Hongbo, Tang Shengjie and Jiang Xinlin.
In 2024, China's space station has planned four launches and two manned spacecraft recovery for a total of 6 missions, so far the launch of the Tianzhou-7 cargo spacecraft, the launch of the Shenzhou-18 manned spacecraft and the recovery of the Shenzhou-17 manned spacecraft, it can be said that China's manned space mission in 2024 has been completed 50%!
Shenzhou-17 carried out a very important mission during its orbit, that is, it completed the repair of the solar wing of the core module of the space station "Tianhe" during two spacewalks. This module is of great significance to the Chinese space station, as its name suggests, it is the core and basic module of the Chinese space station! Since its launch on April 29, 2021, it has been in orbit for 3 years!
The Shenzhou-17 crew's repair work on the solar wing of this module is not because it has reached the end of its lifespan, or because there is a quality problem! But because space is not empty, and human probes orbit the earth, especially the solar wing with a large surface area is often hit by meteorite particles, and damage is an unavoidable problem!
The astronauts can go out of the capsule to repair it in orbit, which is a very critical technology and experience, and this is also the first time in the history of China's manned spaceflight to complete the extravehicular maintenance work of an in-orbit spacecraft!
With the successful landing of the Shenzhou-17 return capsule, it also means that the three-crew six-month space mission has come to a successful end, and then they will return to Beijing Aerospace City for corresponding recovery training. Why astronauts are carried out of the return capsule by medical supervision and medical insurance personnel after returning to Earth, and why they are lying down when they are interviewed, is because the six-month space environment has an impact on the astronaut's body!
To put it simply, astronauts' bones and muscles need to regain adaptation to the Earth's gravity, and of course, after a few months, everyone will still be a good man and will continue to devote themselves to the corresponding training. Especially before 2030, China will carry out manned landing on the moon, and astronauts will also conduct targeted training.
The successful return of the three astronaut crew of Shenzhou 17 also means that the second space journey of Commander Tang Hongbo has come to a successful end, and for Tang Shengjie and Jiang Xinlin, they can be regarded as completing the transformation, and they have grown from aerospace "newcomers" to leaders with flight experience!
For Commander Tang Hongbo, his two space trips were on the space station, so why do you say that Shenzhou 17 landed safely, and the three astronauts were all first?
Because Shenzhou-17 has adopted a five-circle rapid return downlink plan, it takes about 1.5 hours to circle the earth, and five circles of rapid descent is 7.5 hours, and then after about 50 minutes, the return capsule will land safely on the Dongfeng landing field! You must know that this technology was carried out for the first time when the Shenzhou-13 manned spacecraft returned.
Tang Hongbo's Shenzhou-12 mission flew around the earth 18 times when returning to the earth, which took more than a day, which is a great challenge for the astronauts' body and mind!
The three astronauts finished breakfast at the space station, evacuated the space station at 8:43 a.m., and waited until they returned to Earth just in time for dinner! The time has been greatly improved, and it is the first experience for astronauts Tang Hongbo, Tang Shengjie, and Jiang Xinlin! Finally, I hope that the three astronaut crew of Shenzhou 17 will recover well as soon as possible, and the Shenzhou 18 crew will be able to smoothly carry out all the scheduled tasks in the next six months!
Space fish farming is still very much worth looking forward to!
