Animation of Phoenix's Wrist Unlatching
This animation shows what happened underneath Phoenix's Robotic Arm wrist on Sol 3. The pin that goes through the loop is what holds the wrist in place. The rotation of the wrist pops the pin free.
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.
