CTOnews.com March 2 news, CTOnews.com learned from the China manned Space Engineering Office official account that recently, the Shenzhou 15 astronauts carried out the second extravehicular activity. With the close cooperation of the ground staff and the astronaut Deng Qingming, the two astronauts Fei Junlong and Zhang Lu successfully completed all the assigned tasks and returned to the experimental module safely.

The astronauts of Shenzhou 15 took part in the second extravehicular activity.

Astronaut Deng Qingming cooperated in the cabin to support extravehicular activities. At present, more than half of the space business trip of the "Dream come true group" is scheduled. In the three months since they entered the space station, they have successively carried out two extravehicular activities, carried out continuous manned environmental maintenance and care, and completed the assembly tests of several scientific experimental cabinets in the sky-asking experimental module and Mengtian experimental module. At the same time, they also cooperated with the completion of a number of space station cargo unloading missions.

In addition, the scientific experiment project of the space station is progressing steadily as planned and has achieved phased results. Recently, with the cooperation of ground researchers and astronauts, the experimental system in the Mengtian module combustion science cabinet successfully carried out the first on-orbit ignition test, which verified the completeness of the function of the space station combustion science experiment system, as well as the accuracy and scientific nature of the overall experimental process, which laid a good foundation for the smooth implementation of the follow-up project. In addition, the two-photon microscope project of the space station carrying the Tianzhou V cargo spacecraft has also carried out in-orbit experiments and achieved success, obtaining three-dimensional images of the skin and superficial dermis of astronauts during space flight for the first time, providing a new tool for on-orbit health monitoring of astronauts in the future.
