Space Junk?

What is space junk and where does it come from, you ask. Well I'll tell you. Have you heard of about astronauts losing camera lenses in space? Well that lense becomes space junk.

All countries should try to help clean up the space, not just us. Scientists are trying to help but its a big job. Space junk can be dangerous too. For instance on March 12, 2009 a small piece of space junk was headed for our space station. They told astronauts to leave the station because that small piece of junk was going 17,000 miles an hour.

Luckily the space station was not harmed. But lots of little pieces make their way though our atmosphere. Once, it hit a women walking down her street. She wasn't harmed, but that's rather scary. I think if we don't get our space cleaned up soon then people will really start getting hurt. Don't you?
