To infinity and beyond!

If you like Google Earth then Celestia should be right up your street. It's very much like GE except in space.
Windows, Mac, and Linux versions available.

Cool :)

You just inspired me to hunt down Orbiter, which seems to be a pretty nice piece of software which very pleasantly demonstrates why our dreams of becoming astronauts were best left unfullfilled.
Lots of addons, too!

Who the hell cares about a damn planet out in the middle of nowhere. There is no life out of this freaking earth, at least since ET left us...

Orbiter reminds me of Activisions Space Shuttle which was engrossing at its time because it used the Atari VCS hardware switches to control various parts of the journey.

Heh, if the human race was started using your gene pool, we'd all still be living in caves! :P
