Lockheed Martin associate research scientist Monica Leong, prepares and bakes a vegan pizza from a recipe developed for a mission to Mars at NASA's Advanced Food Technology Project at Johnson Space Center in Houston Tuesday, July 3, 2012. NASA is currently planning a mission to Mars, which has gravity, so more options for food preparation, like chopping vegetables, are available as opposed to the dehydrated fare of current space missons.
