Piece of Russian debris almost vaporized Chinese satellite

A piece of space debris from a Russian missile test nearly collided with a Chinese satellite on January 18th. The debris, part of a larger cloud created by a destroyed Russian spy satellite, was tracked by CNSA officials as it passed the Tsinghua Science Satellite at 19,000 km/h. The debris cloud, containing around 1,500 trackable pieces, poses a long-term threat to spacecraft. Although the debris and satellite are currently moving apart, future collisions remain a possibility. CNSA emphasizes the need for international regulations under the UN framework to manage space debris.
