Like proud parents savoring their baby's very first steps, mission team  members gathered in a gallery above a clean room at NASA's Jet  Propulsion Laboratory to watch the Mars Curiosity rover roll for the  first time.   Engineers and technicians wore "bunny suits" while guiding Curiosity through its first steps, or more precisely, its first roll on the clean room floor. The rover moved forward and backward about 1 meter .
 Mars Science Laboratory  is scheduled to launch in fall  2011 and land on the Red Planet in August 2012.  Curiosity is the  largest rover ever sent to Mars.  It will carry 10 instruments that will  help search an intriguing region of the Red Planet for two things:1. Environments where life might have existed
2. The capacity of those environments to preserve evidence of past life
