March 2, news, recently, Shenzhou 15 astronaut crew carried out the second extravegeable activity, in the close cooperation of the ground staff and the astronaut Deng Qingming, two extravegeable astronauts Fei Junlong and Zhang Lu successfully completed all the assigned tasks, safely returned to the space experiment module.

At present, the Shenzhou 15 crew is in the middle of its space business trip schedule. In the three months since it was stationed in the space station, it has carried out two extraveparation activities and carried out continuous maintenance and care of the manned environment.Completed the assembly and testing of several scientific experiment cabinets of the Qentian Experiment module and the Mengtian Experiment module, and cooperated with the space station to complete several cargo capsule missions.

China's space station scientific experiment project is progressing steadily as planned and has achieved initial results, according to the official account of China Manned Space Flight.

Recently, in collaboration with scientists on the ground and astronauts,The experimental system in the Dream Capsule combustion science cabinet successfully performed its first in-orbit ignition test,It verifies the functional completeness of the combustion science experiment system of the space station and the accuracy and scientificity of the overall experiment process, which lays a good foundation for the smooth implementation of subsequent projects.

In addition, the space station's two-photon microscope project, which was carried up by the Tianzhou V cargo spacecraft, has carried out successful in-orbit experiments.Three-dimensional images of the epidermis and the superficial dermis of astronauts' skin were obtained for the first time during a space flight, providing a new tool for on-orbit health monitoring of astronauts in the future.

It is understood that during the Shenzhou 15 manned mission, a number of scientific and technological experiments will be carried out, as well as astronauts and cargo out of the capsule activities.
