CleanSpace One – a Swiss satellite to tackle space junk


More than half a century of sending objects into space has left the Earth surrounded by junk. Bits of long-dead satellites, spent rocket stages and other debris orbit the planet at almost 18,000 mph, each chunk a potential hazard to working satellites or astronauts.

The Swiss have a plan, however. Scientists at the Swiss space centre at EPFL, the federal institute for technology in Lausanne, want to send a “janitor satellite” into orbit, to sweep up debris and permanently remove it from orbit.

The SFr10m (£7m) satellite, called CleanSpace One, could launch within five years, according to EPFL.
