This image taken by the Surface Stereo Imager on NASA's Phoenix Mars
Lander shows the lander's Thermal and Electrical Conductivity Probe
(TECP), at the end of the Robotic Arm, on the 46th Martian day, or sol,
of the mission (July 11, 2008).
The TECP is inserted at a site called Vestri, which was monitored several
times over the course of the mission. The probe's measurements at this
site yielded evidence that water was exchanged, daily and seasonally,
between the soil and atmosphere.
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.
