Mars Exploration Rover team members continued longer-duration test runs
this week, driving the test rover forward and uphill in a crab-like
position. These long-duration drives will continue through the end of next
week.
Engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are using
a test rover in a box filled with soil to mimic the Martian surface to
test a combination of maneuvers that may be used to free the Spirit rover,
which is dug in on Mars in soft soil called "Troy." Pictured are Matt Van
Kirk with Sharon Laubach.
