[Global Network reporter Wen Jiayue] What if there is too much space junk? Russia Today (RT) reported on the 10th that the Russian Space Agency has invented a self-destructive satellite to solve this problem.
According to RT, the satellite is ingeniously constructed and can decompose itself when receiving earth signals. A patent filed with the Russian Federation Intellectual Property Office showed that satellite construction would use sublimation materials, which meant that they would be converted directly from solids to gases rather than liquids, i.e., when satellites lost their usefulness, they would be evaporated.
The problem of space junk has long plagued scientists and engineers, RT said. In 2016, experts from the Central Institute of Mechanical Manufacturing Sciences of the Russian National Aerospace Corporation concluded that if this problem is not solved, all near-Earth orbits will be blocked by garbage and space exploration may be completely suspended.
RT cites data from the European Space Agencys Space Debris Monitoring Agency (ESA) that more than 8,400 tons of space debris are currently orbiting the Earth, most of which are caused by thousands of launches, deployments and waste caused by explosions and collisions.
