This portion of a picture acquired by NASA's Phoenix Mars Lander's Robotic
Arm Camera documents the delivery of soil to one of four Wet Chemistry
Laboratory (WCL) cells on the 30th Martian day, or sol, of the mission.
Approximately one cubic centimeter of this soil was then introduced into
the cell and mixed with water for chemical analysis. WCL is part of the
Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) instrument
suite on board the Phoenix lander.
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.
