SPIRIT UPDATE: Remarkable Rover Continues to Astonish - sol 1200-1206, May 31, 2007:
Spirit is still making new discoveries despite dragging its feet, so to speak, after losing use of the right front wheel 426 sols, or Martian days, ago. In the process of creating small trenches while traversing Martian terrain, the dragging right front wheel revealed one of the most astonishing discoveries so far -- exceptionally high silica content in Martian soil, indicative of water at some point in the past. Two of Spirit's scientific instruments -- the alpha-particle X-ray spectrometer and the miniature thermal emission spectrometer -- measured a composition of about 90 percent pure silica in a soil target known as "Gertrude Weise."
