How many days did the astronauts on China Shenzhou 12 manned spacecraft stay in space?

The astronauts of China Shenzhou 12 manned spacecraft stayed in space for 90 days.

On 20021September 16, the mission command of the manned space station decided that the Shenzhou-12 spacecraft would return to Earth on September 17. On the morning of September 16, the crew of Shenzhou-12 astronauts, with the cooperation of ground technicians, completed the removal of relevant experimental devices and important articles from the core cabin.

Before leaving the space station complex, Nie Haisheng, Liu Boming and Tang Hongbo expressed their gratitude and respect to the scientific and technical personnel on the ground and people who care about supporting the space industry. After the evacuation of Shenzhou 12 manned spacecraft, it completed the flight around and radial rendezvous test with the space station assembly on September 16 13: 38 Beijing time, and successfully verified the radial rendezvous technology.

It laid an important technical foundation for the follow-up manned mission. Subsequently, the Shenzhou-12 manned spacecraft return module will take the opportunity to return, and astronauts Nie Haisheng, Liu Boming and Tang Hongbo will soon embark on their way home. The Shenzhou-12 astronauts have been working and living in the space station assembly for 90 days, setting a new record for China astronauts to stay in space in a single mission.

Spacecraft design;

1, intelligent

The spacecraft's own equipment and parts are constantly upgrading, the technical maturity, quality and reliability of products are also improving, and the intelligent level of the spacecraft is also constantly improving.

2, fault diagnosis

Spacecraft can diagnose and isolate faults independently, and can automatically identify and deal with faults through on-board equipment, thus improving the reliability and safety of platform operation.

3. Docking mode

If the measurement and control equipment of relative position and attitude fails during the automatic docking of shenzhou spaceship with the space station and the core module, shenzhou spaceship can be transferred to astronauts to manually control the spacecraft to complete the docking.

During the docking of the space station, if there is an accident that seriously threatens the life of astronauts, shenzhou spaceship has the ability to leave the space station at any time and return to Earth safely.
