FromTime2021-6-17
On June 17, 2021, Shenzhou XII manned spacecraft, developed by the Fifth Academy of China Aerospace Science and Technology Corporation, was successfully launched.Five years later, when Shenzhou XII manned spacecraft once again carried astronauts into space, it has completed further optimization and upgrading, bringing the comprehensive capability of Shenzhou manned spacecraft to a new stage.
1. The first manned spacecraft autonomous rapid rendezvous and docking was carried out, only 6.5 hours after launch.
2. First orbit and radial rendezvous with the space station
3. Achieved long-term on-orbit docking for the first time, which lasted for 3 months.
4. Capable of returning to the Dongfeng Landing Site from different altitude orbits for the first time
5. For the first time, it has the emergency rescue capability of combining heaven and earth with multiple guarantees. Specifically, the spacecraft team adopts the "rolling standby" strategy, which means that when the first manned spacecraft is launched, the second manned spacecraft will be on standby at the launch site, and has the emergency launch capability of 8.5 days to achieve space rescue.
