Unstable Asteroids

There is an unstable nuclear reactor in space! For whatever reason, your goal is to protect the reactor from random asteroids. Beware that when the asteroids hit the reactor, they make it even less stable. Do not explode!

You can use asteroid dust to stabilize the reactor or to use its instability to explode the asteroids! (Obviously, asteroid dust helps you do that)
