NASA hard at work on menu for Mars trip

Current dehydrated food for near earth missions, which was developed for zero gravity preparation at NASA's Advanced Food Technology Project at Johnson Space Center, is seen at the 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 missions.
