The Robotic Arm on NASA's Phoenix Mars Lander has just delivered the first sample of dug-up soil to the spacecraft's microscope station in this image taken by the Surface Stereo Imager.

The Robotic Arm on NASA's Phoenix Mars Lander has just delivered the first sample of dug-up soil to the spacecraft's microscope station in this image taken by the Surface Stereo Imager during the mission's Sol 17 (June 12), or 17th Martian day after landing.

The scoop is positioned above the box containing key parts of Phoenix's Microscopy, Electrochemistry and Conductivity Analyzer, or MECA, instrument suite. It has sprinkled a small amount of soil into a notch in the MECA box where the microscope's sample wheel is exposed. The wheel turns to present sample particles on various substrates to the Optical Microscope for viewing.

The scoop is about 8.5 centimeters (3.3 inches) wide. The top of the MECA box is 20 centimeters (7.9 inches) wide. This image has been lightened to make details more visible.

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.

Photojournal Note: As planned, the Phoenix lander, which landed May 25, 2008 23:53 UTC, ended communications in November 2008, about six months after landing, when its solar panels ceased operating in the dark Martian winter.
