That Sinking Feeling Ebbs Away At Spirit

Little forward progress for Free Spirit campaign - sols 2137-2143, January 6-12, 2010:

Spirit remains embedded at the location called "Troy" on the West side of Home Plate. Extrication drives were tried on sols 2138, 2140 and 2142 (Jan. 7, 9 and 11, 2010).

Each of these drives employed a new technique of steering the wheels back and forth before driving. This has shown some efficacy at sweeping material out of the wheel tracks and allowing fresh material to slough off the leading trench face providing traction under the wheel.

Slower wheel speeds were also tried on two of the drives. However, even with these new techniques, little forward progress has been achieved. And excessive sinkage continues to occur with each attempt.

Both the right-front and right-rear wheel continue to be non-functional.

Next, Spirit will switch directions and attempt to drive backward to see if that provides better progress.

As of Sol 2143 (Jan. 12, 2010), Spirit's solar-array energy production is 225 watt-hours, with an atmospheric opacity (tau) of 0.490 and a dust factor of 0.539. Total odometry is 7,730.12 meters (4.80 miles).

Just A Few More Approaches To Try For Extrication
Pasadena CA (SPX) Jan 14, 2010
The list of remaining maneuvers being considered for extricating Spirit is becoming shorter. Results are being analyzed Wednesday, Jan. 13, from a drive on Sol 2143 (Jan. 12, 2010) using intentionally very slow rotation of the wheels. Earlier drives in the past two weeks using wheel wiggles and slow wheel rotation produced only negligible progress toward extricating Spirit. The right ... read more
