This closeup shows the size of the computer chip that holds about 35,000 laser-engraved signatures of visitors to the Mars Exploration Rovers at the Jet Propulsion Laboratory. It will be placed on the second rover to be launched to Mars; the first rover already has one. The signatures include those of senators, artists, and John Glenn. The identical Mars rovers are scheduled to launch June 5 and June 25 from Cape Canaveral Air Force Station.
