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've asked about the engineering data before (and I was specifically looking for the periodic Solar Panel output currents) but was told that that's not going to get published. As I understand it engineering data would have to be stringently reviewed to make sure it didn't breach ITAR and that would be too much paperwork for not enough end user benefit and to be fair that was a perfectly reasonable answer.
I haven't been able to find any data on the sampling period for this either so I can't say if it is taken more frequently than once per day. Prior cleaning events have generally been vague about the precise timing - generally indicating that power levels have increased between sols so it is possible that only one sample measurement is recorded per sol. |
