We just released "Astronaut Trivia! Lite v1.0" on the Android Market. It is available to download to your Android, Droid, Google mobile phone. This is a lite version with 2 games of 10 questions each. The subject is U.S. Astronauts and U.S. Space vehicles and programs.
For help, see the FAQ for String Theory Trivia - the games are very similar.
There is also a bonus screen (which is not a game) to help NASA's human spaceflight program, Constellation. For help on this, see the post for SAVE the Astronauts!
