Phoenix Test Sample Site
This sequence of four images was acquired by NASA’s Phoenix Mars Lander’s Surface Stereo Imager on sols 5, 6, and 7--the fifth, sixth, and seventh days of the mission (May 30, 31, and June 1, 2008). The images show the so-called "Knave of Hearts" first-dig test area to the north of the lander. The trench shown is 3.3 inches (8.5 centimeters) wide.
The Robotic Arm’s scraping blade left a small horizontal depression where it first touched the soil on Sol 6, seen in the second image. The third image shows a deeper hole where the Robotic Arm scooped up a a sample on Sol 7. The fourth step in the sequence adds color.
