Opportunity Gets A Timely Dust Off And Regains Energy At The Four-Mile Mark
Pasadena CA (JPL) Nov 22, 2005 Opportunity is healthy. The solar array was apparently cleaned again on sol 638. Average solar array energy is around 720 watt-hours after the cleaning event! Opportunity finished a campaign using the robotic arm on a cobble called "Antistasi." The Moessbauer spectrometer and alpha particle X-ray spectrometer data show that the cobble is very basaltic.
On Sol 645 Opportunity drove 22 meters (about 72 feet) south on an outcrop path around "Erebus Crater." This drive pushed Opportunity's total driving distance past the four-mile mark.
I would like to see the Martian squeegee that keeps out solar panels clean...
