I've been keeping an eye on the sundial images looking for signs of a cleaning event. I've noticed some changes in the latest to be downloaded although they may be due to changes in the lighting.
A : clean patch at top of circle streak at bottom B : increased contrast from dust left behind next to mirror C : clean patch next to wire Also note the missing clumps of dust on the deck A broader view show a contrast between sol 1221 and 1227 http://207.7.139.5/mars/spirit/navcam/2007...I4P0165L0M1.JPG http://207.7.139.5/mars/spirit/navcam/2007...00P1914L0M1.JPG Has anyone heard if there has been a change in the power levels? |

Oersted:
"So much for those theories about the sand only shifting over millenia on the surface of Mars. I never understood those ideas anyway... " They weren't theories, they were observations. No dune, no drift, nothing but the thinnest surface layer of dust, has ever been observed to move before in this way. This is a unique and very important observation. Thanks, Cosmicrocker.
