I think it's time for a new thread.
Opportunity is leaving the area where Kasos and other targets were "sniffed" and imaged, making a 20m drive westwards during sol 1891. Besides, we are reaching the 16km milestone.

Here's a Q&D "post-drive" navcam mosaic.

Edited: we are in "restricted sols", right?

It will be interesting to see what route they take for the next few km. If they stick with driving on rocky terrain whenever possible they will make a big detour to the south west and still have to get across some nasty looking ripples when they move east. On the other hand if they cut east fairly soon they will avoid the bad ripples but have to cover a long distance without firm bedrock beneath the wheels.

I was doing the same questions since we continued SSW after the first science stop.
Right now, I think the path will be over rocky terrain; still SSW for some 700m and then E / SE another 500m or so. The problem, as you said, is after that.

Once this last patch is cleared though, it's clear driving for most of the remainder. That is going to get exciting.

Mmm, no answer so I'll try to do the math by myself... smile.gif

<speculation mode on>
Images/data from sol 1891 were downlinked around 05:30UTC so very late night at JPL. That data will be waiting the whole night (*) until early morning in California when they will be processed by the MER team during the morning shift.

(*) Meanwhile, we at UMSF are already making mosaics, discussing about the future path, etc.

<speculation mode at maximum>
Data/sequences for the next drive should be ready for uplink after one shift (six hours), around 12:00PDT or so. That will be 04:00 local time @ Meridiani, early enough for the rover's morning uplink session.

So, we are NOT in restricted sols. It's time to wheel.gif wheel.gif wheel.gif

How did you know? *I* did not know that I would be done with the sequence by noon today! And I was the RP2 today!!!

Paolo, some of these guys know so much you'll probably have to kill them at some point. Not me, of course. I'm woefully ignorant. Just want to be clear on that.

BTW, will you be able to provide us inside info on how the sandbox testing is proceeding, or is that not for public consumption? Yes, I know, that question should be in the Spirit thread, but I got lazy.

My only source of information on this subject is Scott's blog (Mars and me) about Spirit's early sols. I would be really grateful if you could provide us a brief (or not so brief smile.gif ) description of what is an usual working day for an RP.

That's a good question. A good description of the uplink process can be found in:

"Working the Martian night shift - the MER surface operations process" by Mishkin, A.H.; Limonadi, D.; Laubach, S.L.; Bass, D.S.

and

"From prime to extended mission : evolution of the MER tactical uplink process (2006)" by Michkin, Andrew H., and Laubach, Sharon.

> Sorry for the length of the post ...

What! The lengthy the better, IMO. biggrin.gif
I'll need some time to go through it...

---

And back to "back seat driving mode", I've just checked the data to find that today's drive has already finished beind covered 70+ meters. That places the 16km milestone right at the current position (or perhaps a few meters behind).

Here's the latest navcam mosaic looking due south.

Finished reading it, and really enjoyed. Many thanks for this detailed description! smile.gif
A few questions:
- I suppose the beginning of a shift is conditioned to the downlink time, right?
- All this teams, meetings, peer reviews, are duplicated one for each rover? I assume yes.
