How does Japan plan to clean up the junk flying around in space near Earth?

Answer: by casting a magnetic net

by / January 22, 2014

The junk left in space is potentially dangerous for astronauts and can damage satellites, which is why Japan’s space agency has partnered with a fishing equipment company to create a magnetic space net. The first test, scheduled for February, will examine how effective such a net could be at capturing the estimated 100 million man-made pieces of junk orbiting the earth. NASA estimates that at today’s numbers, a piece of junk larger than 1 cm in diameter hits a satellite every five or six years.
