"Feeling good" again! The third extravehicular activity of the Dream Crew was a complete success

Original title: The third extravehicular mission of the Shenzhou-15 astronauts was a complete success, and the Tianzhou-6 will be launched in May

On March 30, 2023, Beijing time, the Shenzhou 15 astronaut crew conducted its third extravehicular activity . With the close cooperation of ground staff and astronaut Deng Qingming in the cabin, the two extravehicular astronauts Fei Junlong and Zhang Lu successfully completed all the assigned tasks and returned safely to the Wentian laboratory cabin.

Since the Shenzhou XII manned flight mission in 2021, the four-astronaut crew has carried out a total of 10 extravehicular activities, breaking through and mastering a series of key technologies. Currently, extravehicular activities have become routine work for astronauts in orbit, and will continue to be carried out on a regular basis according to mission needs.

The space station modules, manned spacecraft, cargo spacecraft, relay satellites and the Long March series of launch vehicles used to launch these spacecraft used in China's space station project were all developed by the China Aerospace Science and Technology Corporation . Relevant units of the Aerospace Science and Technology Corporation also participated in other subsystems of the project.

In the fourth month just past, with the coordinated cooperation of ground staff, the "Dream Crew" completed various tasks as planned, including space station platform maintenance and care, in-orbit maintenance, and extravehicular installation of material extravehicular exposure test equipment.

At present, the space station scientific experiment project is progressing steadily as planned. Recently, the China Space Station, which is led by the Fifth Academy of China Aerospace Science and Technology Corporation, has made new achievements in the field of aerospace technology experiments. Its space high-efficiency free piston Stirling thermoelectric conversion test device has successfully completed the on-orbit test , and its comprehensive technical indicators such as thermoelectric conversion efficiency have reached the international advanced level .

It is reported that as a new technology for spacecraft power systems, the Stirling thermoelectric conversion system can efficiently convert thermal energy into electrical energy, reducing dependence on solar energy. It has broad application prospects in future manned lunar and deep space exploration missions.

In addition, the Tianzhou-6 cargo spacecraft has been safely transported to the Wenchang Space Launch Center in advance, and is carrying out assembly and testing work at the launch site as planned. It will be launched at an appropriate time in early to mid-May .
