The test sample shown was taken from the digging area informally known as "Knave of Hearts." Scientists speculate that the white patches on the right side of the image could possibly be ice or salts that precipitated into the soil.

One week after landing, the lander practices digging.

One week after landing on far northern Mars, the Phoenix Mars Lander lifted its first scoop of Martian soil as a test of the lander's robotic arm.

The practice scoop was emptied onto a designated dump area on the ground after the Robotic Arm Camera photographed the soil inside the scoop. The Phoenix team plans to have the arm deliver its next scoopful, later this week, to an instrument that heats and sniffs the sample to identify ingredients.(Click here for full image.)

A glint of bright material appears in the scooped-up soil and in the hole from which it came. "That bright material might be ice or salt. We're eager to do testing of the next three surface samples collected nearby to learn more about it," said Ray Arvidson of Washington University in St. Louis, Phoenix co-investigator for the robotic arm.

The camera on the arm examined the lander's first scoop of Martian soil. "The camera has its own red, green and blue lights, and we combine separate images taken with different illumination to create color images," said The University of Arizona's Pat Woida, senior engineer on the Phoenix team.

The Phoenix mission is led by Peter Smith at the UA with project management by NASA's Jet Propulsion Laboratory, located in Pasadena, Calif., and development partnership at Lockheed Martin, located in Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.
