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? |

Currently it's Mid Southern Hemisphere Summer - the sun is 85.5 degrees above the horizon at noon for Spirit.
100 sols from now - that figure will be 74 degrees and it will be Early Autumn 200 sols from now - 56 degrees, Mid Autumn 300 sols from now - 50 degrees, Early Winter 400 sols from now - 60 degrees, Mid Winter 500 sols from now - 81 degrees - Early Spring. Basically it's the 150 to 450 sol's in the future period that will be the worst of it That's all using the mars24 applet - our resident Purveyor of Whr's might be able to do a better job Doug Off topic posts from after 30 October moved to new thread: http://www.unmannedspaceflight.com/index.php?showtopic=4837 Alan |
