Spirit Digs Its Trench
Feb. 23, 2004 — Spirit excavates a trench seven centimeters (three inches) deep. The soil at this location is more cohesive and sticky than the material where Opportunity dug its first trench at Meridiani Planum. Spirit made 11 back-and-forth passes to dig this trench, and still did not produce as deep a hole as Opportunity dug in six passes.
