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? |

Ah, yes, deposition or clean sweep?
Seriously, I agree with Gordan here - we can actually see the process through the front hazcam animations posted above, with wind pushing little ripples along and erasing tracks. We've heard in press releases that all the dust in the air would only be the thickness of a human hair or so if it all settled out, so that shouldn't be enough to have much effect on the topography. |

...I agree with Gordon here... It's "Gordan," fredk, with an "a." Those of us who were brought up on Sesame Street always want to type "Gordon," but he's not the same guy! --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
