Oh very cool, heres to crossing my fingers you get stationed in an area you enjoy. As for satellites it is my basic understanding that with old satellites they push them up into a higher "junk orbit" or send them on a course to burn up in the atmosphere. I've always kind of wondered why they just don't shoot them completely out of orbit? does this take too much energy? I figured I would ask and maybe you would know the answer =)
Besides the political and economical challenges of shooting down a satellite it is also very difficult to do. The thing is when you hit it with an ICBM, as the U.S and China have done, the satellite just doesn't go poof and disappear. You actually form hundreds of pieces which remain in orbit and are still dangerous to other satellites.
Here's what happened when China blew up their satellite in 2007. It's nto a great video but it gives an idea:
If you could come up with a valid way to remove space junk you would become very wealthy very fast.
