The rocks of "Hillary Outcrop" (1) - Sol 634

NASA - Official Status Report:"Spirit is healthy and spent the week examining a rock called Hillary at the true summit of Husband Hill.
The first attempt to approach Hillary ended with a small pebble under Spirit's left front wheel, and the stability of the Rover was uncertain.
A set of wheel wiggles was performed to stabilize the Rover before deployment of the Robotic Arm (RA). Once the wheel was in good contact with the ground, Spirit began a conservative RA campaign that started with Mössbauer Spectrometer and Alpha Particle X-ray Spectrometer integrations".
