Spirit is now parked for the winter in the embedded area called "Troy" on the west side of Home Plate.

The last winter-preparatory movement of the rover was commanded on Sol 2169 (Feb. 8, 2010).

The rover was commanded to flatten the suspension system on the right side and accentuate the suspension wheelie on the left side, all to enhance northerly tilt.

Very little change in tilt was achieved.

At this point, the project is now adjusting various rover parameters and positioning the robotic arm for the winter period.

The communication window for various fault conditions has been adjusted to the optimal time of day during the coldest part of the winter.

A special table of long-range UHF communication passes is being developed to cover the entire winter period and beyond.

As of Sol 2170 (Feb. 9, 2010), the rover solar array energy production was to 185 watt-hours with an atmospheric opacity (tau) of 0.292 and a dust factor of 0.527. Total odometry is 7,730.50 meters (4.80 miles)
