Space is getting a little crowded. Since the 1950s and 60s, we have been launching things into low earth orbit at nearly a constant pace. All this means that there’s quite a bit of space junk now floating around the earth. As this space junk breaks up and turns into smaller space junk, the available safe areas that we can launch new things into space grow smaller. In essence, there might soon be an impenetrable orb of space debris around the earth preventing any future missions. The video below goes even deeper into this potential problem.
