Update on Pictures and Energy figures (odometry unchanged):

Thanks, Dilo. If you look at the Whr curve, you can see what looks like a jump of roughly 15-20% in power at around sol 2800, which is when we pulled into the north-facing winter haven.

Good catch, Fred. Below a zoomed portion of the plot highlighting the jump and guessing power trend without it:

As Oppy drives over eight years now on Mars, I post the updated timeline of the MER mission now.
As milestones I took Homestake and Greely Haven.

Awesome as usual! A wonderfully succinct summary of two long adventures. A couple of very minor typos: you're missing an 'n' in Endurance, an 'e' in Greeley, and a 'c' in Concepcion.

I really like that too. smile.gif I didn't read the small print but I notice that this winter looks shorter than previous ones. Is there a reason for that?
dilo
Great work, MoreInput!
I integrated your Oppy timeline with my full odometry (implementing Emily's corrections):
brellis
wow! That's the most concise telling of her story yet!

Thank dilo, for putting these two diagrams together. So they are now much more informative than they are alone.

I just corrected some errors (typos, length of winter) in the timeline diagram, and marked just the next solar conjunction far away on 18th April 2013.

Update showing recent energy increase due to slight Tau/Dust improvements:
climber
Tomorrow, Spirit will be sitting on the surface of Mars since her landing 3000 Earth days ago. Oppy's coming along.

New update shows a dramatic drop of picture rate (only 2/sol) in the last half-month! I do not have an explaination...
Deimos
FYI, the data tracking site shows an average of >20 pictures taken and >20 pictures downlinked per sol over the last 15 sols, so the problem may be elsewhere. (The exact number depends on how you define picture--I looked at total EDNs + ESFs + EFFs downlinked; and at ETHs to determine how many images were successfully acquired.)
dilo
Deimos, I confirm your figures looking at the picture counts from different cameras; however total counter in the upper portion of the official MER page gave me 166290 pictures on March,17 and 166320 pictures on March,30 and this imply only 2pic/day average! as additional info, this counter wasn't updated for several days before yesterday and, at this point, it seems there are problem with it!
djellison
That's not a great place to pull the total number of images taken. That's the number of images taken,downlinked, piped thru the raw processing pipeline and uploaded to the JPL image page.

Energy only update:

Consider that Oppy stopped driving when energy dropped below 300 Whr, almost 5 months ago...
