Rover engineers check how a test rover moves in material chosen to
simulate some difficult Mars driving conditions. The scene is inside the
In-Situ Instrument Laboratory at NASA's Jet Propulsion Laboratory,
Pasadena, Calif. These tests in early May 2005 were designed to help plan
the best way for the rover Opportunity to drive off of a soft-sand dune
that the rover dug itself into the previous week. The mixture of sandy
and powdery material brought in for these specific tests matched the way
the soil underneath Opportunity caked onto wheels, filling the spaces
between the cleats on the wheels.
