Congratulations! Mission accomplished!

The Shenzhou 15 astronaut crew successfully completed the first extravehicular activity and all the scheduled tasks. The space station cargo extravehicular installation mission was also carried out in the early stage.

The reporter learned from the China Manned Space Engineering Office that at 0:16 on February 10, after about 7 hours of extravehicular activities, Shenzhou 15 astronauts Fei Junlong, Deng Qingming and Zhang Lu worked closely together to successfully complete all the scheduled tasks of the extravehicular activities. At present, astronauts Fei Junlong and Zhang Lu have safely returned to the Wentian laboratory module, and the extravehicular activities have been a complete success.

During the EVA, the astronauts completed tasks such as the installation of the Mengtian module's external expansion pump set, and the whole process went smoothly. This was the first EVA of astronauts after the full completion of the Chinese space station. Astronauts Fei Junlong and Zhang Lu walked in space for the first time, and successfully fulfilled their dreams again. According to the plan, the astronaut crew will carry out multiple EVAs in the future.

In addition, the space station cargo extravehicular installation mission has also been carried out in the early stage. At present, the energy particle detector, plasma in-situ imaging detector and other payloads have been installed outside the cabin, fully verifying the extravehicular payload installation process and the functional performance of the space station cargo airlock, transfer mechanism and other components.

According to reports, the cargo extravehicular installation mission of the space station is coordinated by the payload transfer mechanism, cargo airlock, internal and external hatches, and robotic arms. Through on-orbit astronauts or ground operations, cargo that needs to be extravehicular is sent out of the cabin, and cargo outside the cabin can also be sent into the cabin according to mission needs. Breakthroughs in this key technology can greatly improve the efficiency of cargo exchange inside and outside the cabin and reduce the number of astronauts' extravehicular activities and workload. According to the plan, cargo extravehicular installation work will continue in the future.
