Junk in Space

Like the Earth's environment, the space environment is getting more and more cluttered. There are currently MILLIONS of man-made orbital ruins that make up "space junk". Unfortunately, the past 45 years of space exploration have generated a lot of junk!

Space junk can be anything from hatches blown off space modules, paint fragments from the space shuttle, or satellites that no longer work. Man-made debris orbits at a speed of roughly 17,500 miles/hour (28,000 km/h)! Think of the damage even a small speck of paint could do if it hit a spacecraft at such a high speed!

We need your help to capture junk that's floating out there in space. But be careful not to capture working satellites, spacecraft, or astronauts--three strikes and you're out!
