NASA has been working on lots of things, like satellites, rockets, spaceships, and, will you believe it, games. NASA’s “Moonbase Alpha” game is now available for free download on Steam. NASA describes the game as a “First Person Explorer”, which, given the setting and point of the game, is a pretty accurate description.

NASA has revealed that their anticipated MMO about space exploration will have a demo out early January. The MMO uses actual NASA simulation technology used to simulate the return to the moon in 2020, where players will have the ability to explore the moon, and in the future, Mars as well. The game, officially titled “Astronaut: Moon, Mars and Beyond”, is expected to be released in Q1 of 2010. Check out the first gameplay video of the title at NASA.
