Twelve-year-old Clara Ma flew from Kansas to JPL to meet and sign the next rover that will zoom millions of miles to Mars. The trip is Clara's prize for winning an essay contest in which she named the rover "Curiosity."

Clara, a sixth-grader from Sunflower Elementary school in Lenexa, Kan., got a VIP tour of JPL, along with her parents and sister. Inside the building where Curiosity is being assembled, Clara donned a "bunny suit" to step into the clean room and sign her name on the rover. The trip to JPL was provided by Walt Disney Studios Motion Pictures.

Clara and her family also visited the Mars Yard, where future generations of rovers are tested. For more information about the next rover mission, go to http://www.nasa.gov/msl .
