Curiosity Cam takes you inside the clean room at NASA's Jet Propulsion Laboratory in Pasadena, Calif., so you can watch the next Mars rover being built.
Technicians assembling and testing the Mars Science Laboratory, aka Curiosity, are covered head-to-toe in "bunny suits." These white smocks, booties and facemasks help protect against Earthly contaminants hitching a ride to Mars.
