This morning, Shenzhou 14 was successfully launched. Three astronauts, Chen Dong, Liu Yang and caixuzhe, flew to the China Space Station in the Shenzhou 14 manned spacecraft, stationed in the core module and stayed in orbit for six months. You know what In fact, before the launch of Shenzhou 14, Shenzhou 15 was ready at the Jiuquan Satellite Launch Center
Access:
The Shenzhou 15 spacecraft will not only "meet" with Shenzhou 14 at the space station, but also undertake an emergency rescue mission: "if Shenzhou 14 fails to return, it is necessary to launch a rescue spacecraft in an emergency to return the astronauts to the ground."
Safety always comes first in manned spaceflight. In order to ensure the safety of astronauts, the Shenzhou spacecraft and the Chang 2F rocket have adopted the mode of "one active and one standby" to enter the space station era**
Both backup rockets and spacecraft have the ability of rapid launch and emergency rescue. This mode of "one active and one standby" has become the normal task of China's space station.
If everything is normal, Shenzhou 15 will meet Shenzhou 14 in orbit in space six months later. At that time, Shenzhou 14 will return to the ground, and Shenzhou 15 will stay in the space station to continue its mission.
