NASA's MMOG Astronaut: Moon, Mars and Beyond is currently being developed, but a demo called Moonbase Alpha will be available on Steam sometime before or after January 2010. Moonbase Alpha explores the NASA Constellation program for the year 2020, while the full MMOG, Astronaut: Moon, Mars and Beyond is set further in the future around the year 2035. Considered a STEM-learning game, this MMOG is sponsored by NASA Technologies and a short video of the gameplay can be viewed here.
