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.

The camera may be turned off periodically for maintenance. The rover may occasionally be out of view as it is moved around the clean room. When Curiosity Cam is off air, you will see a slideshow of Mars and rover images.  -
