Second, China people's own spacesuits have succeeded. To realize spacewalk, a set of reliable spacesuit is needed, and the spacesuit has to be tested many times. The spacesuit developed by China was successful when it was put into use for the first time, which shows that China has mastered the technology of spacesuit. It is said that each set is 65.438+0.6 billion yuan.
Third, realize the separation of spacecraft and small satellites. This is also the most distinctive feature of Shenzhou VII. Shenzhou VII released a small satellite, the main function of which is to monitor the operation of Shenzhou VII and take photos, and of course, take photos of astronauts' spacewalks. The small satellite is in the same orbit as the spacecraft and keeps a distance of 4 kilometers from the spacecraft. In addition, releasing small satellites through spacecraft is also a new way of launching satellites.
Fourth, spacewalk. The core of space technology is to let human beings into space, and all technologies and experiments are carried out around this goal. Shenzhou VII achieved a spacewalk, which is a milestone in China's space flight.
Fifth, the new features of Shenzhou VII carrier rocket. Compared with the rocket that launched Shenzhou VI spacecraft, this rocket has 36 technical improvements, including monitoring, shock absorption and safety.
Of course, success is accumulated bit by bit, and behind it is the hard work of many experts. However, compared with the United States, China's space technology still has a long way to go. As an American expert said, "China's space technology is in the primary stage".
On the morning of September 27th, the astronauts took turns to rest. For the first time, Shenzhou VII crew set up the post of commander, which was held by 0 1 astronaut Zhai Zhigang. Zhai Zhigang will also leave the cabin this afternoon. Liu Boming will help Zhai Zhigang put on his spacesuit and conduct a series of scientific experiments in the orbital module.
