The crew on board Shenzhou-15, China's space station has completed their second extravehicular activity, also know as spacewalk, according to the China Manned Space Agency (CMSA) on Thursday.

Fei Junlong and Zhang Lu have successfully completed all the tasks for the spacewalk and returned to the space station with the help of the ground team and their teammate Deng Qingming, who stayed inside Shenzhou-15 during the spacewalk to provide support.

The three taikonauts have been living in orbit for three months since they entered the space station combination on November 30, 2022, which is half of their planned mission

The Shenzhou-15 mission wrapped up the last stage of the space station construction and commenced the first stage of its application and development.

They have completed various tasks, including two extravehicular activities, continuous maintenance of the manned environment in the space station, the assembling and testing of the scientific experiment cabinets in the Wentian and Mengtian lab modules, and moving cargo out of the space station.

First in-orbit ignition test

The scientific experiment projects in the space station have been advanced as planned and have obtained initial results, according to the CMSA.

With the cooperation of ground researchers and taikonauts, the cabinet for combustion science in Mengtian lab module has carried out its first ignition test, which proved it's ready for further science projects.

In addition, the crew successfully obtained the three-dimensional structural images of their skin cells with the country's self-developed two-photon microscope early this week, which provides new tools to check taikonauts' health in orbit.

The Shenzhou-15 crew is expected to conduct a number of science and technology experiments and more spacewalks.
