Pancam Mast Assembly The pancam mast assembly will stand from the base of the rover wheel 1.4 meters tall. The pancam mast assembly serves two purposes: • To act as a periscope for the Mini-TES science instrument that is housed inside the rover body for thermal reasons • To provide height and a better point of view for the Pancams One motor for the entire Pancam Mast Assembly head turns the cameras and Mini-TES 360º in the horizontal plane. A separate elevation motor can point the cameras 90º above the horizon and 90º below the horizon. A third motor for the Mini-TES elevation enables the Mini-TES to point up to 30º over the horizon and 50º below the horizon. During cruise, the Pancam Mast Assembly lays flat against the top of the rover equipment deck in a stowed configuration. After the lander opens on the surface of Mars, pyros release the bolts holding it down.
