PASSPORT TO KNOWLEDGE - To MARS with MER

Daily Updates - February 11, 2004
Spirit Status at end of sol 38

On Spirit's sol 38, which ended at 6:40 a.m. Wednesday, PST, a failure to receive data during the morning high-gain communication window quickly led engineers to conclude that Spiritís high-gain antenna was not pointed toward Earth. Spiritís orientation after the previous sol's drive (45 degrees to the northeast) caused its camera mast to cast an early-morning shadow on the high-gain antennaís elevation actuator. The cold conditions caused the actuator to stall and fail to point to Earth while being calibrated. The afternoon high-gain communication session performed flawlessly.

The afternoon communication window with Mars Odyssey provided previously acquired images of the rocks Adirondack and White Boat and a miniature thermal emission spectrometer observation of the depression drilled by the rock abrasion tool on Adirondack.

In coming sols Spirit will perform daily "touch and go" maneuvers, inspecting the soil surrounding it with the instruments on its arm, then continuing its drive toward the crater nicknamed "Bonneville."
