FIDO features a stowable mast that reaches 1.94 meters above the ground when unfolded (as viewed to the right). The head of the mast contains two stereo imaging systems, the
Pancam and Navcam, and optics for the Infrared Point Spectrometer.
Also seen in this image is part of the calibration target for the imaging system.
It is the small rod protruding vertically from the solar panel (to the right of the mast). The rod sits in the center of the calibration target. The white pole to the left of the mast is the wireless ethernet antenna that FIDO uses to send telemetry and receive commands.
