Dec 02, 2009 · It could have moved a fair amount of material, but the techniques they used were based on sand. Much of the regolith they gathered fell out of their scoop as they were trying to scoop more. When the scoop was set too deep, the vehicle tended to dig itself in. Eventually, the front right wheel stopped working. 2009 Regolith Excavation Summary

In-Situ Resource Utilization (ISRU) will enable the long term presence of humans beyond low earth orbit. Since 2009, oxygen production from the Mars atmosphere has been baselined as an enabling technology for Mars human exploration by NASA. However, using water from the Martian regolith in addition to the atmospheric CO2 would enable the production of both liquid Methane and liquid Oxygen

Planetary Robotics. Dynamics and control of wheeled rovers for lunar/planetary exploration have been addressed. In general, extraterrestrial surfaces like the Moon or Mars are covered with fine soils (regolith), and thus better understanding of interaction between a wheel and soil is necessary for achievement of rover missions.
