Space Debris Threatens Earth and Space Missions
There are millions of pieces of space debris orbiting Earth, which can cause problems for spacecraft.
Recently, China's Shenzhou-20 spacecraft had small cracks in its window due to debris impact, making it unsafe to return.
China launched another spacecraft, Shenzhou-22, to bring the astronauts back safely.
Experts say this shows how serious the space debris problem is and that we need better ways to track and manage it.
They also suggest that countries and companies should work together to make space safer for everyone.
Earth is surrounded by 130 million pieces of space debris, including remnants from rocket explosions, abandoned satellites, and broken equipment.
The growing debris increases the risk of collisions, leading to more debris in a phenomenon called Kessler syndrome.
China's Shenzhou-20 spacecraft had small cracks in its window due to debris impact, postponing the astronauts' return.
China launched the unmanned Shenzhou-22 spacecraft to bring the astronauts back safely aboard Shenzhou-21.
Experts call for better global tracking, accountability, and international cooperation to manage space debris and ensure safety.
