This anaglyph image, acquired by NASA’s Phoenix Lander’s Surface Stereo Imager on June 1, 2008, shows a stereoscopic 3D view of the so-called 'Knave of Hearts' first-dig test area to the north of the lander. 3D glasses are necessary to view this image.

This anaglyph image, acquired by NASA’s Phoenix Lander’s Surface Stereo Imager on Sol 7, the seventh day of the mission (June 1, 2008), shows a stereoscopic 3D view of the so-called “Knave of Hearts” first-dig test area to the north of the lander. The Robotic Arm’s scraping blade left a small horizontal depression above where the sample was taken.

Scientists speculate that white material in the depression left by the dig could represent ice or salts that precipitated into the soil. This material is likely the same white material observed in the sample in the Robotic Arm’s scoop.

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA’s Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.
