Shao Limin: This year, Shenzhou 13 will implement a rapid return for the first time

On February 9, China Aerospace Science and Technology Corporation held a press conference on the Blue Book of China's Aerospace Science and Technology Activities (2021) (hereinafter referred to as the Blue Book) in Beijing. Shao Limin, deputy technical manager of the manned spacecraft system project of the Fifth Academy of Aerospace Science and Technology Group, said at the press conference that this year, the Shenzhou manned spacecraft will carry out the return as planned, the two ships rendezvous and docking, and the three ships of emergency rescue standby, involving a total of 4 Shenzhou spacecraft from Shenzhou 13 to Shenzhou 16. At the same time, the ground research and development of Shenzhou 17 and Shenzhou 18 will also be carried out in parallel. Shenzhou 13 will implement rapid return for the first time, further improve the comfort of astronauts and the efficiency of mission implementation, comprehensively verify the functions and performance of manned spacecraft, further test the reliability and safety of the standard space-space round-trip transportation system for the application and development of the space station, and establish a management system for the parallel development, launch, docking, return and on-orbit of multiple manned spacecraft under high-density launch missions.

As we all know, after the cargo spacecraft is on the sky, the next thing to see is the manned spacecraft. Escorting the manned spacecraft is the Long March 2F carrier rocket. This year's manned spacecraft missions have shown the characteristics of high density, normalization and diversification. Among them, after completing the maximum 6-month combination docking task so far, the Shenzhou 13 manned spacecraft plans to perform the return mission in mid-April, using a rapid return plan, and landed at the Dongfeng landing field. What is the Fast Return scenario? Shao Limin, deputy technical manager of the manned spacecraft system project of the Fifth Academy of Aerospace Science and Technology Group, explained that it used to take a day to return, and this time we can greatly reduce the time to improve the comfort of astronauts.

Shao Limin said: "In the past, many return work was serial, and after doing one piece, I would do the next one. Now there will be some changes, one is to parallel some tasks, such as during the docking of the assembly can do some preparation for the return, rather than after the assembly is separated, which will save some time, and some calibration actions, the degree of compactness between the action and the action is compressed, but the software and hardware on our ship are not changed. ”
