Space Debris and Clean Space One

The video discusses the issue of space debris, starting with the launch of Sputnik I in 1957, which led to a growing amount of space junk. This debris poses threats to satellites and astronauts. The Swiss have initiated a program called Clean Space One to address this problem by removing debris, starting with their own satellite, Swiss Cube. The mission involves using advanced propulsion and grabbing technology to capture and deorbit space junk. The video highlights the challenges and future plans for systematic debris removal to ensure space remains accessible.
