On nov 12th, Oppy's odometry went from 34200m to 34250m putting her record since Jan 1 st over the 7740m mark which is what her Spirit sister drove in her entire Life.
Also, the total odometry of MER rovers was 42058m on Nov 16th short of 137m from having roved a FULL Marathon!

5000 Sols! Think about it: FIVE-THOUSAND-SOLS.
Oppy's today on sol 2790 and Spirit last call was on sol 2210.
This is quite a milestone.
Ready for the challenge, Curiosity? wheel.gif

only 61cm covered in last 20 Sols (average speed of 3.1 cm/Sol or 1.3 mm/hour or 0.36 um/sec!)
Happy New Year, Oppy!

This topic seemed to be the best place to slide this in...

I think there is a 'year change' bug on the Mars Rover website. The SOL clock is about 353 days off...

Opportunity is currently at SOL 2821-ish
The SOL clock says 2468

Has happened every year (possibly since prime mission) where they have to go in manually and put in an appropriate constant. Usually takes about two weeks. No one working on that site has wanted to rewrite the code that would go out several years in advance--since how probable is that that the rover(s) will really last another year rolleyes.gif

Get rovers to Mars ... check. Operate them many years past their design life ... check. Write clock software without a Jan 1 bug .. not so much? smile.gif

The time of sol seems to have been off every time I've been there recently, too. The clock at http://www.lpl.arizona.edu/~lemmon/mars-tau-b.html is accurate. I expect it to not have a leap year bug or anything, but we'll see. (I'll link an MSL clock to the site eventually--sol -210, 20:01:00 as I write, if I've got it right.)

And Tman's clock differs from Deimos's since the first gives local true solar time and the other hybrid local solar time - is that right, Tman? The sun would be due south at noon LTST, is that right?

The Sun crosses the meridian at noon LTST (whether to north or south depends on site and season). The LTB time at the bottom of Tman's page is also accurate for for HLST.

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.
