I was wondering if there is a simulator that you can fly in spce and dock with the space station, or land on the moon.
I've never tried it, let us know what you think of it.
It seems ok, the grafics aren't that good, but they're alright. So far I haven't figured out how to use it. It's a pretty good sim for being free.
They have a manual and a web-board, you might find help there.
They have add-ons at avisim I think.
