Hey all, I just searched the forum for discussions about this game but, apart from one of the developers asking a question about astrophysics, I found nothing. In case folks don't know... there exists a wonderful game/simulator called "Kerbal Space Program" developed by a group called "Squad." The game, in a nutshell, is a rocket-building game with a full-featured orbital mechanics simulator integrated. Right now it's in alpha-stage development and is just a sandbox-style game; design your rocket(s) and plan/execute your own missions. This includes everything from sub-orbital flights with a nice parachute-slowed splashdown to crew-lander-dropping skycrane maneuvers on one of the two currently-available moons! There's a huge third-party developer community which provides new rockets parts and even plugins like auto-pilot, lunar mining, and user-controllable rovers. Here's a picture of a skycrane I built dropping a rover I designed near a lunar arch formation. As a side note, the first moon is called "Mun" and the second, smaller moon, is called "Minmus." The game is addictive, fantastic, and well worth the current $18 price tag. I'm not at all affiliated with the design group, and I don't get anything for pushing the game. I'm just hoping someone else will be introduced to the game and will love it as much as I do! Also, all rights belong to the design group. My screenshot also shows some third-party parts including the MechJeb autopilot system.
