This image taken by the Surface Stereo Imager on July 14, the 49th Martian day of the Phoenix Mars mission, shows the robotic arm’s scoop and silver-colored rasp. The scoop is inverted and the rasp is pointing up. Mission scientists have been using the rasp to drill into the icy layer that lies just beneath the Martian soil surface.
