Space Junk: The Growing Threat to Earth's Orbit

The video discusses the issue of space debris, which includes thousands of objects orbiting Earth, from small fragments to large satellites. Since the launch of Sputnik in 1956, the number of objects in orbit has increased, leading to a significant amount of space junk. This debris poses a threat to spacecraft and satellites, as collisions can cause explosions and further debris. Efforts are being made to mitigate these risks, including guidelines for deorbiting redundant satellites. The European Space Agency is actively addressing the issue, but concerns remain about the potential for future collisions if mitigation measures are not followed.
