Finally had a chance to look again at the sheets that Climber so kindly made available some 9 months ago.

On Sol 437/8 Oppy had covered 5,225 metres to give an average of 11.96 mtrs/sol.

On Sol 2635 Oppy had covered approximately 31,343 metres to give an average of 11.89 mtrs/sol.

Oppy needs to gain about 170 metres on top of 11.96 mtrs/sol to break her own record which has stood since April 2005.

As nearly a half year is over, I post a new update of the mission timeline.

The sad milestone is that Spirits mission is now over. Hey, it lauchend over 8 years ago (10th June) ... what a time.
For Oppy there are just two points: Leaving Santa Maria after the solar conjunction, and reaching 30 km.

Some facts:
For the first 10 km Opportunity need 1108 (earth) days
For the second 10 km Opportunity needed 1143 days.
And for the third 10 km Opportunity needed just 435 day.

If dilo has time to update the total odometry sheet I will integrate the milestones again.

New update (slightly in advance due to imminent holidays... ):

Ii is not possible to attach an .ods file, I will try through email...

As dilo so kind to send me the statistics sheet and the odometer plot, I repaint the integrated drive statistics / mission timeline again.

Nothing really new just more km on the odometer.

A neat combo', thank you both.

You're welcome, beautiful work!

Evening all,

According to Teshiner (post no. 722 on the 'Post Conjuction thread') Oppy's 5 hour driving marathon is now scheduled for sol 2645.

To break her 6 year old average distance per sol I estimate she will need to cover 156.46 metres during that drive.

Just a reminder (as if one was needed) that this is a machine now in her 30th 90 day phase and her 32nd 1km warranty!

Neil

And it appears she has! If the reports on the post conjunction thread are correct Oppy travelled 121m + 41m on sol 2645 = 162 m

This means she beats her previous average by just 2mm per sol!

Neil

For those of us of a statistical bent today's drive may be yet another significant one for Opportunity as it might have reached 31,788m on sol 2649. If so, this would see her break the 12m per sol barrier. If not today it would appear to be only a matter of time until she does, but it could be her final barrier.

With Cape York and all the other wonders of Endeavour Crater now approximately only 1.5kms away it would appear unlikely that this record will be greatly extended again before we become engrossed in the scientific investigation of Spirit Point and beyond.

Neil

If Oppy rolls down into Endeavour, she could pick up some speed!

Neil, I never considered this intriguing aspect of "grand-average" speed...
Based on my dataset (official JPL weekly reports) the 12m/sol record was already broken in the "glory" week, immediately before "soft dune stall":

Dilo,

Thank you so much for correcting me! I'm assuming sol 2652 has seen us finally break this record?

Neil

You're probably right, Neil... I'm waiting for official figures (they are not being updating them since June 28!).

Last updated report gives 11.954 m/sol average (Sol 2647, 31,630.68 m), very close to a new record... in the following week (ending today) we need additional 230 meters only in order to break the old record!

edit: ...and based on last Theseiner's map, Oppy already made a 150m progress from sol 2649 to 2652...

According to my record, the odometer is currently at 31920m; 31630 from the last official report plus 140m on sol 2649 and 149m on sol 2652.

Even if we rely "only" on the Official odometry, on sol 2647 (july 5th 2011) we were at 11.950 m/sol which breaks the old record of 11.924 on sol 438 (april 16th 2005). Anyway Eduardo's figure shows that we are over 12m/sol now. Using this last figure, we are now 350 m short of reaching 40 kms total for Spirit + Opportunity. (or 2545m short of a full Marathon)

Climber, my figures are slightly different about previous record (11.96 m/sol on sol 437 and 12.00 on Sol 442) but, at this point, no doubt it was broken in the last days (12.04 on Sol 2652 based on Theseniner data above). So this is my updated plot:

I come back to this old post to make an update and rise a question/challenge.
New figure shows Oppy now n° 3:
Lunokhod 2 / 37.00 km
Apollo 17 rover / 35.89 km (max distance to LEM 7.2)
Opportunity (2652) / 31.92 km (max distance to lander 17.8)
Apollo 15 rover / 27.76 km (max distance to LEM 5.0)
Apollo 16 rover / 26.55 km (max distance to LEM 4.6)
Lunokhod 1 / 10.50 km
Spirit / 7.73 km
Sojourner / ?

The question/challenge is to find out the maximum distance to the landing base reached for each of the above since this is also a way to compare rovers achievements. Already included what I've found here: http://nssdc.gsfc.nasa.gov/planetary/lunar/apollo_lrv.html

PS for Dilo re previous post: I've got weekly figures only so, on a sol by sol basis, you're probably right, thanks

For Sojourner you can put in approximately 85 m.

Phil

Thanks Phil,

I'm having hard time finding figures for the Lunakhod (max distance to the landing base). I was looking for the LRO's pictures you once posted here for then trying to measure myself (unless you've got the real numbers) but was not good enough using the search tool.
I'll guess Oppy is still n°2 in this regard since I believe Lunakhod II roved more or less "strait" in one direction.

Looking quickly at the route map, it appears Lunokhod 2 reached a point approximately 15 km from its landing site. It drove south, east and north again, with other diversions from its route as well. I'll post a map in a lunar thread.

Phil Stooke

With Phil's help and last Oppy drive, here is the whole figure regarding the 8 planetary rovers.

Actual total roving distance
1. Lunokhod 2 / 37.00 km
2. Apollo 17 rover / 35.89 km
3. Opportunity (2654) / 32.00 km
4. Apollo 15 rover / 27.76 km
5. Apollo 16 rover / 26.55 km
6. Lunokhod 1 / 10.50 km
7. Spirit / 7.73 km
8. Sojourner / 0.085 km

Actual maximum distance from landing base
1. Opportunity (2654) / 18.05 km
2. Lunokhod 2 / 14.39 km
3. Apollo 17 rover / 7.2 km
4. Apollo 15 rover / 5.0 km
5. Apollo 16 rover / 4.6 km
6. Spirit / 3.62 km
7. Lunokhod 1 / 2.26 km
8. Sojourner / 0.01 km

I hope we drive further than the Apollo 17 rover ...

Update (it was a little tricky to find all information on the renewed MER site):
Click to view attachment
Note1: Due to high speed of Oppy, I had to reduce total odometry scale on the right of lower plot, in order to show all the progress in last martian year...
Note2: the new grand-average speed record is now official: 12.06 m/sol on sol 2655!

Nice looking actually
Where did you find it as been "Official"?

Nothing explicit, simply my figures based on last JPL report...

Ok, good enough, I though I was missing something. So, to me, it's as Official as Eduardo's route

As of July 19th, Spirit + Oppy total > 40 km... AND 25 miles (40.283 and 25.027)

End-of-month update:

Besides some aesthetic changes (most evident is the Odometry plot on top, because I think is the most important!), I added also atmospheric Opacity and DustFactor trends on the energy plot (scale is on the right for both); I think many of you will appreciate!

Yes! Thanks, Dilo!

The new Dust Factor is a really cool feature! thanks, dilo

Tosol's 2700 for Oppy
She completes her 30th nominal mission.

NASA may need to extend the mission for a 31st.

Yeah!

I think they should change the background now ...

Increasing Tau and worsening dust factor, joined to seasonal variations, are bringing total energy below 320 Whr/sol...

EDIT: I updated plot in order to show Spt,28 data and zero-speed odometry in last 3 weeks.

According to Mars Daily, Oppy has passed the 21-mile mark and is close to 34,000 meters.

Actually, she crossed the 34km mark during the last drive on sol 2754.

Update to Sol 2763 (Nov. 1, 2011):

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?

Update!

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

http://marsrover.nasa.gov/home/index.html

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

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?

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.
