China News Service, Beijing, November 30th (Ma Shuaisha Gao Xiaolei) On November 30th, the Shenzhou 15 manned spacecraft successfully completed a fully autonomous rapid rendezvous and docking with the Chinese Space Station.
For the first time, China has realized the configuration of three ships and three cabins of the space station, and six astronauts are stationed in orbit at the same time.
It is reported that after the Shenzhou 15 manned spacecraft docked with the space station, the Chinese space station finally formed a configuration of three cabins and three ships, namely the "three cabins" of the Tianhe core module, the Wentian experimental module, and the Mengtian experimental module, and the Tianzhou-5 cargo spacecraft. , Shenzhou 14 manned spacecraft, Shenzhou 15 manned spacecraft "three ships".
This is the first time that two Shenzhou manned spacecraft have docked at the Chinese space station at the same time. Carry out information transmission, ventilation and heat exchange, grid-connected power supply, etc.
It is understood that during the rotation of the two crews, the space station will transmit the telemetry of the two ships through different docking buses to ensure the uniqueness and correctness of the information transmission of the two manned spacecraft.
The space station system will provide ventilation and thermal support to the two manned spacecraft at the same time. The air supply volume will be reasonably distributed according to the different thermal environments of the two ships, and can be adjusted in stages according to needs.
In response to the situation where the two ships docked at the same time, the researchers formulated a coordinated and matching emergency evacuation strategy to ensure the safety of the astronauts.
With the successful docking of the Shenzhou 15 spacecraft at the Chinese space station, the newly stationed astronaut crew will first hand over the astronauts of the Shenzhou 14 astronauts in orbit, and then continue to verify the mission of the space station during the 6-month "space business trip" The ability of astronauts to stay in orbit for a long time.
Shenzhou 12 to Shenzhou 15 spacecraft are the first batch of Shenzhou spacecraft produced in China.
From the Shenzhou 12 spacecraft that successfully achieved rapid rendezvous and docking for the first time on June 17, 2021, to the Shenzhou 13 spacecraft that first implemented radial rendezvous and docking on October 16, 2021, to the current Shenzhou 14 and Shenzhou 15 The spacecraft docked at the space station at the same time, forming an unprecedented combination of three cabins and three ships in the Chinese space station, realizing the first time that six astronauts were in orbit at the same time, and China's manned spaceflight ushered in a new breakthrough.
In order to meet the high-density mission requirements of 2 rounds per year and rolling standby during the mission phase of the space station, the manned spacecraft system adopts a batch development model, and a total of 4 manned manned spacecraft, Shenzhou 12 to Shenzhou 15, were launched during the key technology verification and construction phase of the space station. spaceship.
During the more than 40 days of working at the launch site, the manned spacecraft test team needs to complete the Shenzhou 15 launch and Shenzhou 16 emergency rescue standby preparations in parallel.
