What should the aerospace science and technology tabloids write?

Contents of handwritten report on aerospace science and technology knowledge:

1. What are the special feelings of astronauts wearing clothes in space?

Astronauts' spacesuits are usually no different from those we wear on earth, except for special requirements for comfort and safety. For example, clothes must be made of fireproof materials. When astronauts wear spacesuits in weightlessness, they are actually floating in the clothes. Only when clothes touch the skin will they feel that they are wearing clothes.

2. How many people can the space station hold?

The International Space Station can accommodate up to seven astronauts. The number of astronauts increased from 3 at the beginning to 6, and in 2003 to 7. Of course, it is impossible for all the staff to return immediately in case of an accident. This is why NASA must improve the return capsule to accommodate more people than the Russian Soyuz spacecraft. ?

How do astronauts on the space station spend their spare time in space?

They have different preferences according to their own preferences. During the flight, they can choose their favorite entertainment activities. Some can read books or send emails to their families on laptops, some are listening to music or playing games, and some are just chatting with relatives and friends on the ground or chatting with other colleagues. However, when most astronauts first entered the space station, they spent most of their spare time standing at the window, looking out at the universe and watching the earth disappear from under the space station.

4. Land reconnaissance satellites 3 and 4?

On 20 18, 10/3 and March 17, China successfully launched the land exploration satellites No.3 and No.4 with the Long March II carrier rocket at Jiuquan Satellite Launch Center, and the satellites entered the scheduled orbit. The satellite is mainly used for remote sensing exploration of land resources.

5. Zhang Heng No.1?

2065438+February 2, 2008, China successfully launched the electromagnetic monitoring experimental satellite "Zhangheng No.1" into the scheduled orbit by the Long March II carrier rocket at Jiuquan Satellite Launch Center. It marks that China has become one of the few countries in the world with high-precision geophysical field detection satellites in orbit.
