About future energy availability, I made the following plot comparing last daily watt-hours (red points) with corresponding trend in previous martian year, obtained by shifting the date 670 Sol back:

There is a strange time shift between the two trends (50-100 sols) and last data seems almost 100 Whr below corresponding energy of previous year trend; anyway, if trend is confirmed, Oppy needs to reach a new winter site within November...

If you look at http://www.lpl.arizona.edu/~lemmon/mars-tau-b.html you'll see that we get basically the same peaks and troughs each year - but there's often a lag early or late depending on how the weather is doing. Regional dust storms I think can bring spikes forward or push them back.

Updated charts, energy trend decreasing again:

(last update on Sol 3344)
Note1: Total odometry in the last two Opportunity Status Reports is given with tens-of-meters precision, contrary to previous ones; if somebody knows more precise figures, this would help in calculating accurate average speed...
Note2: It seems now Status Report is bi-weekly! http://marsrovers.jpl.nasa.gov/mission/sta...ity.html#recent

Just for fun and curiosity I'd like to find out what was the Oppy's record in weekly traverse distance - what was the maximum distance trvelled within any 7 following sols.
Do we have somewhere here a list of all sols traveled distances from sol 1 up to tosol?
Can some MER statistics master share such (excel) file with us?
Thanks

It was sometime after leaving Endurance, I recall (sol 400 or so).

See the chart in this post, with the huge spike around that time: http://www.unmannedspaceflight.com/index.p...ost&p=85751

410      220
408      190
412      183
414      183
383      177
413      175

Thank you both, guys. It is realy amazing, she did once more then 960 meters within 7 sols!
And yes dilo, I'm interested for sure. smile.gif

Actually, she covered 1.4 km in 10 days! this happened just after a new navigation software was uploaded, around sol375, then Purgatory stall occurred on Sol446. After this tough experience, she never exceeded 100m for a while!

A little late, but here is the time line of Oppys incredible journey until July 2013.

Thanks for timeline, MoreInput!
I integrated it with my updated Opportunity odometry plot (I added also some old daily records previously omitted):

Only one (noteworthy) dust storm in all this time; eventually there will be a global event again right? Hope Oppy fares as well as last time...
