WASHINGTON, June 2 (Xinhua) -- One week after landing on far-northern Mars, NASA Phoenix spacecraft lifted its first scoop of Martian soil as a test of the lander's Robotic Arm, NASA reported on Monday.

    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.

    A glint of bright material appears in the scooped up soil and in the hole from which it came. "That bright material might be iceor 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.

    Phoenix touched down at a northern Mars plain on May 25. During the next three months, it will dig through the soil to look for ice or organic compound that shows signs of favorable environment for life.
