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? |

"I doubt they get engineering data at a high rate all the time the puter is powered up. Maybe not much or any when it's more or less on standby. Generally, I think events will probably happen between blocks of data.
Anything after sunset and before sunrise can't be detected by solar power changes regardless of whether the rover is taking data or not! |
