Attaching Curiosity's Mast

In this image, engineers at NASA's Jet Propulsion Laboratory are dressed head to toe in "bunny suits" (white hoods, lab-style coats and gloves). Only their eyes and foreheads can be seen. They are huddled around the base of the rover Curiosity's "neck" (its Mast). They watch intently as they carefully lower the Mast to attach it to the rover's flat "back."A cluster of yellow and red wires on the rover's body pokes up in the foreground of the image.
