At about 10 o’clock on April 16, the Shenzhou 13 manned spacecraft return capsule successfully landed at the Dongfeng Landing Site, and the astronauts returned safely. It is little known that during the 183 days of the astronauts’ stay in orbit, the basalt fiber cloth has been on the space station, silently guarding them.
With the development of the aerospace industry, the amount of space debris continues to increase, which seriously threatens the safe operation of spacecraft. It is reported that the enemy of the space station is actually the debris and micrometeoroids formed by space junk. The number of large-scale space junk that has been detected and numbered exceeds 18,000, and the total number that has not been detected is as high as tens of billions, and all of this can only be relied on by the space station itself.
In 2018, the Russian Soyuz spacecraft claimed that air leaks were caused by damaged cooling pipes. In May last year, the 18-meter-long robotic arm of the International Space Station was penetrated by a small piece of space junk. Fortunately, the staff found it in time and carried out follow-up inspections and repairs to avoid more serious consequences.
In order to prevent similar incidents, my country has used basalt fiber cloth to fill the defensive impact protection structural materials of the space station, so that the space station can protect the space station from high-speed impacts with fragments up to 6.5 mm in diameter.
The basalt fiber cloth jointly developed by China Aerospace Science and Technology Corporation Fifth Research Institute Space Station and Zhejiang Shijin Basalt Fiber Co., Ltd. has been applied to my country’s space station. As a key material for space debris protection structures, it can effectively crush, melt and even gasify. projectile, and reduce the speed of the projectile, so that the ability of the space station to resist the impact of space debris at a speed of 6.5km/s has been increased by more than 3 times, which has greatly improved the orbit reliability and safety of the space station, exceeding the protection design index of the International Space Station.
