Tesheiner, I read about the 10K mark, and was hoping that you had updated the route map to show the excursion that put us over the mark -- and you didn't disappoint!

By the way, I'm thinking that Oppy's getting ready to head back to Duck Bay, which looks like the past entry path, plus nice vertical cliffs to examine on the way in . . .
glennwsmith
Of course I meant best entry path . . .

I don't know about that. I think from what Squyres has said, they're more likely to enter the crater in the next three or four bays.

I'm thinking that this last drive, up and away from the rim, is a set-up for a short sprint straight east into the dark streaks. Oppy can then work south towards the rim through the major dark streak, characterizing the soils outside the streak, inside the streak, and along the boundaries.

They're going a funny way about it....and why would you pick an entry point after seing less than 1/4 of the rim, especially when we've been told they plan to cover something like 120 degrees of crater rim.

Maybe they're heading for that crater on the annulus with the pale east rim, then on to the first dark streak? Clealry, they are mssing out Cabo Corrientes. From the area where the first streak meets the rim of Victoria, they'd get a good view of the boulder field inside the crater, the biggest and best collection of tumbled-down rock anywhere inside Victoria. They come from the beds of the layered cape above it (Cape D 1). My guess is they'd like to use those boulders to sample different layers of the strata in the crater wall.

Mmm, I would guess they are still planning to drive onto Cabo Corrientes.
Here is the rationale: The "post-drive" mosaics taken on sol 1080 were headed at 144º, meaning that the rover driver's primary interest for the next move is centered on that heading. In other words, it might be possible that the next move is on heading 144º i.e. towards Cabo Corrientes.
Now, the next move is already planned; it's on sol 1082 (today). Among the planned imaging sequences is, again, the "post-drive" navcam mosaic this time centered at 162º. Based on the previous assumption that today's move will be headed at 144º and (another assumption) the post-drive navcam mosaic is centered on the cape tip, I did the following picture with Opportunity's possible (?) location after today's move.
My two cents.

OT: FWIW, sol 1082 activities include one more Phobos transit imaging session.
kenny
Tesheiner, I'm sure you're right about the clues given by the imaging instructions. But I can't understand why they went so far away from the rim to the 1080 position, only to turn around and double back in again, when there's nothing that requires such a big avoidance maneuver. The route from 1078 to 1080 is at an azimuth of about 50 degrees, whereas something about 80 degrees would have taken Oppy much more quickly and efficiently towards Cabo Corrientes.... unless they've gone out there to look at something.

Because they had better drive-direction visibilty that way and could be sure of zero hazards over a longer drive that way? Because they wanted to get some navcam terrain model wedges to augment the ones they will get closer to the rim and build a better model of this area? Because they wanted to test some long distance autonomous driving far from the rim? Loads of reasons why they'd do it. How close to the edge of a jagged cliff do you walk.....blind fold smile.gif

If you look at the point reached on sol 1066, you can see that it is also further than apparently necessary away from the crater. They are likely searching for a vector to the cape tip that minimizes the chance of falling off an edge. It may be because they are testing auto-navigation and want to give the computer a margin of safety.

Whether the rover goes 20, 30 or 40m on a drive, it can still easily complete it in the time required by the plan so it probably doesn't matter a whole lot (unless you are counting wheel revs) how far they drive.

We can dream, can't we? biggrin.gif

Imaging info from yestersol move (1082) already made their way to the PCDT web, but the exploratorium have no new pics yet. A minor hiccup I would say.
Assuming the mobility data is accurate (and it usually is), this is Opportunity's new position:

I will update the route map once we have some pics.

Looking at the 1082 position, we couldn't really fault Tesh's prediction, could we !!?? biggrin.gif

On sol 1082 Oppy took a curious looking Phobos eclipse sequence - the movement of Phobos looks odd, almost as if it changes direction! I think what happened was the sun was slightly overexposed (notice also how the sun is slightly elongated), and somehow that caused the weird apparent motion. Local time was around 14:25, frames are 3 seconds apart.

Hard to say, but I wouldn't be a bit surprised...Meridiani seems more & more like the "Allan Hills" of Mars, but I bet the ice caps are even more fun! smile.gif

Doug, thanks to you & JB for the enhancement of the eclipse sequence...makes sense now.

Not that I'm aware of. Perhaps this image was taken late in the evening?

On another topic, 1087 is a driving sol.

Curiously, the imaging plan includes a sequence (front_hazcam_wheel_sub_256x256_4_bpp_pri_19) which was *only* used before in three events: stuck at Purgatory, stuck at northern Erebus, and stuck at Jammerbugt.
No, I'm not saying the rover is stuck. It might be related to the new driving technics.

I think it's just our old friend auto-stretch. Those atmosphere shots tend to give a very dark foreground. Local time of shot about 10:30am.

How about the "battlebot spin"
CosmicRocker
Compared to the drunken wobbling, I call this ballet. I'm wondering, might this be a method to create a large, distinguishable track feature that could be recognized by the software for a greater distance? That might allow sober walking for some distance afterward.
Tesheiner
Whatever purpose it has, they did it again.
Sol 1087 which is almost finished was another driving day and the "post-drive" hazcam pics show that same zig-zag pattern.

Edited: Short drive; less then 4m. At this pace we won't be at Hoy neither "hoy" nor "mañana" (that's for you Climber).

Considering that the feature is captured in the downsampled Navcam navigation images, I'd say it's an extra good guess it's used for navigation.

Whoa! back up he truck. this is what, as kids, we would call "doing donuts" after a rain, we'd go out on a grass soccer field and vandaliciously spin the car around with the accelerator gunned and the steering wheel pegged (no, we never got caught, darn kids!).

It looks like the puzzling driving as seen around Sol 1078 - 1082 may have been due to the live testing of the Field D* autonav software:
