Looks like it's time for a new thread! On to Santa Maria!

The 2405 hazcams are down: it looks like we've made it to the flat patch:

As others have pointed out, this isn't the end of the ripples, but it does give us our first taste of the tarmac surface ahead. wheel.gif wheel.gif

Nav/Pancam are expected to be shot and downlinked tomorrow and I expect to see very flat surroundings, at least if I take the HiRISE view as a reference.

Holy smokes! Flatness!

If Occam had heard my theory, things would be very different now.

Very exciting! And these are the images from yestersol (2404) - as Tesh says, 2405's Navcam/Pancam still to come.

And the reason why they are expected tomorrow and not today can be clearly seen on mhoward's mosaic. The rover's autonomous attitude knowledge has drifted a lot so it's time to recalculate it again. The mosaics will be shot after that.

Seems like it drifts more than it's corrected these days. But maybe that's just because they're moving quickly; I'm okay with that. laugh.gif

Here is the full resolution HiRISE image from here to Santa Maria with my ripple map colour overlay showing all the features we have to encounter. It looks like the very flattest bit (greenest on my map) is just ahead. Lots of the parking lot intact has very small ripples, craters, Anatolia like features, more bedrock, etc. Doesn't look like we'll get bored! smile.gif wheel.gif wheel.gif wheel.gif

I hope the nav computer of oppy won't get bored. If the environment doesn't have good identifyable landmarks the computer cannot calculate from the pictures, how far the rover has driven.
We had this problem in the near of Victoria.

The distant dark spot beyond 'A' is visible in the Post #452 image above. (The 124 degree heading)

Agreed. Here's a map showing a few more identifications farther afield, with Phil's 2402 stitch-n-stretch:

Crater G now appears to be the farthest identifiable feature on the plains - it's about a third of the way to Cape York.

My impression is that we can basically see all of the plains now, up to the near rim of Endeavour. In fact, as we drop down towards Endeavour, the view of the plains may become less impressive. We may now be at the "HOAV" point. This would be a great spot for a superres Endeavour pan...

I think you're right, Fred - this may be the optimum shot... until... wow, just wait until we get to that distant rise and finally look down into Endeavour! OK, let's all shout "super-res" and see if anyone hears us.

Updated my blog with some pics showing how the ground beneath Oppy's wheels has changed dramatically...

(and thanks to fredk for letting me use his brilliant pics, too)

Great articles, as usual, Stu.
Just a correction to the second picture, that one with the distances to all little craters up to the "Waypoint": it's about 270m (and not 1.7km) to that crater.
