Jet Propulsion Laboratory https://www.jpl.nasa.gov/ Jan. 16, 2004
Footage taken at the JPL In-Situ Instruments Laboratory, or "testbed," shows engineers practicing the deployment of the test rover's robotic arm before doing the real thing with the Mars Exploration Rover Spirit at Gusev Crater on Mars. Spirit successfully deployed its robotic arm, which carries four geological instruments, over martian soil early Friday morning. (1/16)
