(PhysOrg.com) -- NASA will begin transmitting commands to its Mars exploration rover Spirit on Monday as part of an escape plan to free the venerable robot from its Martian sand trap.
(PhysOrg.com) -- Engineers using test rovers on Earth to prepare for extracting the sand-trapped Spirit rover on Mars have added a new challenge to their preparations.
(PhysOrg.com) -- In the past several weeks, scientists at NASA's Jet Propulsion Laboratory finished experimentation on methods to get the rover Spirit unstuck from its location near a plateau called Home Plate.
(PhysOrg.com) -- Mars rover team members are planning a long-duration experiment with the test rover at JPL beginning next week. This test will check whether favorable motion seen in earlier tests can be sustained to gain ...
Mars rover engineers at JPL are winding down testing of different escape maneuvers using a test rover in a sand box filled with soil to mimic the Martian surface. It is possible that in early August the first extraction attempts ...
(PhysOrg.com) -- Mars rover team members have begun a new phase of testing at JPL -- using longer-duration experiments -- in their preparations for driving Spirit again on Mars.
The Mars rover team is using a test rover at JPL to assess various extraction techniques that might get Spirit out of the loose soil of "Troy" on Mars.
(PhysOrg.com) -- Scientists have combined a trio of shots taken seconds apart through different colored filters to create a special-effects portrait of a moving dust devil on Mars.
Using a test rover in a sandbox at JPL with special soil simulating Spirit's predicament on Mars, engineers are assessing possible maneuvers for getting Spirit out and onto firmer ground.
Engineers placed a rock underneath the test rover at NASA's Jet Propulsion Laboratory, Pasadena, Calif., on July 1, 2009, to more closely simulate Spirit's predicament on Mars.
