[Explanation] At 8:11 on July 4th, astronaut Liu Boming successfully opened the exit door of Tianhe core module node module. As of 11:2, astronauts Liu Boming and Tang Hongbo were wearing a new generation of "Flying" independently developed by China. "The extravehicular spacesuit has been successfully exited from the Tianhe core module node module, and has completed the installation of foot stoppers and extravehicular workbenches on the robotic arm. Subsequent cooperation will be carried out with the support of the robotic arm. Assemble related equipment outside the space station.
During the period, the astronaut Nie Haisheng in the cabin cooperated and supported two astronauts out of the cabin to carry out extravehicular operations.
At 14:57, after about 7 hours of exiting activities, the crew of Shenzhou 12 astronauts worked closely together and successfully completed all the scheduled missions during the exiting activities. Astronauts Liu Boming and Tang Hongbo returned to the Tianhe core capsule safely, marking a sign The first astronaut out of the capsule during the Chinese space station stage was a complete success.

This time the space station’s exit activity is a substantial improvement compared to the original Shenzhou-7’s first exit. First of all, the space station’s astronaut exits the space station. The space station’s exit guarantee is compared to that of the Shenzhou-7 manned spacecraft. It has made some progress, including the preparation of astronauts for exiting the cabin, which has been greatly improved.
【Explanation】Compared with the mission of Shenzhou VII, this time, the mission is longer and the task is heavy. At the same time, the cooperation between man and the extravehicular manipulator is required for the first time, and the complexity is greatly increased.

On the one hand, the astronaut out of the cabin is to verify his crawling outside the cabin, and on the other hand, it is to verify that the astronaut is standing on the robotic arm, and the robotic arm drives the astronaut to carry out large-scale activities outside the cabin. A qualitative leap, this also marks that our exit activities have reached a world advanced level.
[Explanation] From the first manned spaceflight of the Shenzhou V spacecraft in 2003, to the astronaut exit of the Shenzhou VII spacecraft, to the rendezvous and docking of spacecraft, and the long-term stay of astronauts, China's space technology has continued to achieve major leaps.

This is because the astronauts’ work in the complex is actually much heavier and more complicated than the second phase of our manned spaceflight project.
In the follow-up, we will also ensure that the astronauts can carry out related work smoothly in orbit. In this regard, we still have to cheer up, maintain our morale, and support the astronauts to carry out follow-up work.
[Explanation] It is reported that after the three astronauts have completed their in-orbit missions, the "Shenzhou XIII" flight crew launched in October this year will take over their work.
At that time, they will carry the return capsule, return to the earth's atmosphere, and land at the Siziwang Banner Landing Field in Inner Mongolia.
