Ms. Trosper says Spirit's operators are extending its instrument arm to brush the Martian dust from Adirondack, get close-up images with its microscope camera, and determine the rock's mineral content with an infrared sensor. She notes that they will use an abrasion tool Tuesday to scratch below its surface before moving on to its next target.

The metal surface showed signs of abrasion after years of use.

The doctor cleaned the small skin abrasion on her knee.
