I've been looking at the new entries at the PDS for WHR quotes, to compile as good a list of actual quoted Whr values as I can......so if you find one, add it to this thread and I'll update this post with figures....any source as long as it's an actual figure and an actual sol.
B0515 - 418 Whrs B0522 - 462 Whrs |

Just got word from JB
"Spirit is down to about 360-370 Whr and Opportunity is down to about 540-55 Whr" Doug |

Just got word from JB "Spirit is down to about 360-370 Whr and Opportunity is down to about 540-55 Whr" Doug Time for a graph. anyone? Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Time for a graph. anyone? Here ya go Spirit Power is down significantly compared to my prediction at the last check point. My previous estimate had it at 416whr for Sol 774. At this rate it would drop below 300 whr on Sol 829 and below 280 on Sol 849. If a more hospitable environment isn't ound she would drop to 245whr between sol 923 and 938 Opportunity Opportunity is also down somewhat - I had anticipated it would be at 571 whr at this point . At this rate the minimume power level looks to be 405whr between Sol 902 and 924. The lower power levels for both rovers might indicate that dust levels are up (which would be unexpected I think) or it might just be unfavourable orientation. |

Opportunity
Opportunity is also down somewhat - I had anticipated it would be at 571 whr at this point . At this rate the minimume power level looks to be 405whr between Sol 902 and 924. [/quote] So the Trek to Victoria could become a race against the time. If this trend (dust-induced power loss dropps more rapidly than predicted/expected) then we will hit the "operational limit" in significantly less than 100 Sols. So in order to rech the Victoria slopes in time we should be really making not much less than 20 meters per Sol of driving *on average* which seems pretty fast IMO Any guesses about the average meters per day Oppy could realistically make in the terrain towards Victoria ? And, ehr yes: keep up praying for those cleaning events |

If this trend (dust-induced power loss dropps more rapidly than predicted/expected) then we will hit the "operational limit" in significantly less than 100 Sols. At the moment I still don't think that Opportunity will fall below a level at which it can still drive for at least an hour a day but if it is dust deposition that is causing this rather than orientation or an increase in Tau then who knows. Any guesses about the average meters per day Oppy could realistically make in the terrain towards Victoria ? Depends on the type and density of dunes and we don't really know what's ahead yet. On a good pavement she should be able to cover 20-40m even when power drops to 400whr. Around Sol 320/325 she covered 60-80m on sols when she was generating not much more power than she is now (540-600whr) And, ehr yes: keep up praying for those cleaning events Oh yes. |
