Dust Busting on Mars

September 6, 2007
Mars doesn't have a power grid for running a vacuum cleaner, but the red planet has a way of sweeping things clean. Recently, the Martian wind tidied up a mess on Opportunity's robotic arm, which had become caked with dirt during recent dust storms. Extending that newly cleaned arm may bring new discoveries soon. With spic-and-span solar panels boosting solar power, Opportunity may have enough vitality to venture into Victoria Crater, the largest yet explored by either rover.
