Since I know that some of you are totally hooked on the Space Program, I thot that this would interest you (if you didn’t know already).
Found the “Orbiter Space Flight Simulator” which is just like the MS Flight Simulator, but it’s a freeware and it lets you fly into space, dock on stations, collect satellites, land on the moon, other moons and other planets (Mars).
Til now I’ve only tried the getting into space, archiving a steady orbit and then landing back on earth with the Delta flyer. You can also use Space Shuttels to recreate previous missions. The program can be found at: http://orbit.medphys.ucl.ac.uk/home.php
Fly safely!
