Talk about a growth-spurt. In one week, Curiosity grew by approximately 1 meter (3.5 feet) when spacecraft technicians and engineers attached the rover's neck and head (called the Remote Sensing Mast) to its body. At around 2 meters (about 7 feet) tall, the next rover to Mars now stands head and shoulders above the rest.
Mounted on Curiosity's mast are two navigation cameras (Navcams), two mast cameras (Mastcam), and the laser-carrying chemistry camera (ChemCam).
While it now has a good head on its shoulders, Curiosity's "eyes" (the Mastcam), have been blindfolded in a protective silvery material. The Mastcam, containing two digital cameras, will soon be unveiled, so engineers can test its picture-taking abilities.
Up next today (July 23), the towering rover will take its first baby steps: a slow roll on the floor of the clean room where it's being built at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Watch Curiosity's progress live from the clean room on Ustream until 3:30 p.m. PDT today: http://www.ustream.tv/nasajpl .
