I created this thread because the old one from 2011 is out of date, the OP is no longer correct, and the original poster is no longer active.
Kerbal Space Program (KSP) is a space program simulator available on the PC for Windows, OSX, and GNU/Linux (Link).
The game combines a building phase, where players create aircraft, spacecraft, and ground vehicles, with a sandbox phase where those craft are launched, flown, and landed. It includes a sandbox mode with all parts unlocked, and a career mode where players must unlock tiers of technology by collecting "science". The science points are awarded for various feats such as obtaining soil samples, performing EVAs, or monitoring scientific experiments in different places.
KSP roughly simulates our solar system, with several planets, some of which have moons. Each celestial body has its own terrain, heightmap, and physical characteristics such as gravity, orbital period, rotational period, and the like. Through significant trial and error, it's possible to create elaborate space stations and remote outposts. The builder is very deep and it's possible to create some wacky structures.
It is not free, though there is a demo (Link). It's available from the aforementioned website as well as Steam. It also has its own very informative wiki (Link)
It's definitely worth looking into.
As of 2014-12-15, version 0.90, "Beta Than Ever" is now available (Link)
FAQs:
Why isn't KSP 64-bit?
-Because Unity, the engine upon which KSP runs, doesn't have proper 64-bit support on all clients. (Link)
-As of 2014-07-15, version 0.24, there is 64-bit support for Windows.
Why isn't KSP properly multithreaded?
-KSP is multithreaded, but Unity isn't multithreaded in a way which results in the sharing and offloading of physics calculations (Link). There are supposed to be some physics improvements in the new version of Unity (Link)
