China News Agency, Jiuquan, October 14 (Ma Shuaisha) Lin Xiqiang, deputy director of China's Manned Space Engineering Office, said at the Jiuquan Satellite Launch Center on the 14th that the Shenzhou 12 mission process was smooth and the results were successful, creating many "firsts". At present, the Shenzhou 12 flight crew has completed the isolation and recovery phase as planned, and will soon be transferred to the recuperation and recovery phase.

　　The press conference for the Shenzhou 13 manned mission was held at the Jiuquan Satellite Launch Center on the 14th.

Lin Xiqiang said at the meeting that the Shenzhou 12 mission created many "firsts". First, it was the first time that Chinese astronauts stationed on the Chinese space station; the second was the first three-month long-term residence of astronauts; and the third was the first manned presence. Autonomous rapid rendezvous and docking was shortened from the original two days to 6.5 hours; fourth, the astronauts used a robotic arm to perform extravehicular operations for the first time.

　　Fifth, for the first time in orbit, comprehensive and systematic verification of regenerative environmental control and life support technology; sixth, for the first time to realize the dynamic management of on-orbit materials; seventh, for the first time to fly a three-aircraft combination; eighth, for the first time to implement manned operations at the launch site Spacecraft and manned rockets are on standby for emergency rescue, verifying the "rolling backup" strategy; nine is the first astronaut search and rescue mission at the Dongfeng Landing Site; ten is the operation planning center, the astronaut support center, and the spacecraft on-orbit support center. For the first time, this support center has realized the "centralized + distributed" flight control support mode under long-term manned conditions.

　　Lin Xiqiang said that during the Shenzhou 12 mission, the functional performance of the project's various systems to perform the space station mission was verified. The process was smooth and the results were satisfactory, and the mission set goals were successfully achieved.

Through the implementation of the mission, the astronaut crew and engineering systems have gained valuable experience, laying a solid foundation for the construction and operation of the space station.

　　According to reports, on the basis of completing the established training plan, the ground staff arranged for the "Shenzhou XIII" crew to communicate with the "Shenzhou XII" crew. After the Shenzhou 12 crew returned, the two crews and backup The astronauts had full exchanges, sharing the experience and feelings of the "Shenzhou XII" crew in orbit, especially for the out-of-vehicle activities, fully exchanged the matters needing attention in the difference between heaven and earth, and the Shenzhou 13 crew carried out corresponding measures. Training lays the foundation for entering the state in advance and performing tasks smoothly.

　　Lin Xiqiang also said that the recovery work of the astronaut crew after returning to the ground is divided into three stages: isolation recovery, recuperation recovery, and recovery observation.

On September 17, the Shenzhou 12 astronaut crew returned to Beijing Aerospace City on the same day they returned. Currently, the isolation and recovery phase has been completed as planned. The three astronauts are in good physical and mental health and will soon be transferred to the recuperation and recovery phase.
