IT House January 9 news, according to CCTV reports, all Russian civil defense and emergency science research experts recently said that more than 170 million space debris under 1 centimeter is flying around the earth, flying speed of up to 56,000 kilometers per hour, the current total mass of near-Earth space debris is estimated to reach 6500 tons.
Experts point out that for spacecraft launched from Earth, even colliding with 1 centimeter of debris can lead to serious consequences such as disintegration and further generate more new debris.
IT House understands that space debris refers to the product of human space activities. Including rocket arrow bodies and satellite bodies that complete tasks, rocket jets, discards in the process of carrying out space missions, and debris generated by collisions between space objects, etc., are the main sources of pollution in the space environment.
According to our years of research accumulation, China has established a space debris collision early warning system, high-risk rendezvous analysis software, orbit anomaly analysis system, and disintegration event analysis software package.
According to the official introduction, we now have the ability to risk assess the risk of different sizes of space debris collisions before the launch of the satellite, the early warning capability of large debris collisions near the launch and during orbit operation, and the ability to analyze space debris-related emergencies, including high-risk rendezvous event analysis capabilities, disintegration event analysis capabilities, orbit anomaly analysis capabilities, etc.
