It seems Oppy has moved again although it's hard to put any numbers on how far we have travelled. I don't see any features in the latest navcam, forward and rear hazcam images.

Oppy is currently doing some major driving, possibly exceeding previous records, over a 3-sol period (driving on all sols). Considering that the previous driving record is something like 156 meters or so per sol (someone please correct me), that should put us around 450 meters south of Jason crater by Wednesday.

Now that is some serious driving! I like it cool.gif

But are they planning to drive both forward and backward on these long traverses? To put an even load onto the drive mechanism.

Yes, it's a standard procedure now to do that, for both Spirit and Opportunity. I don't know the distance though at which point they switch, or what other criteria is used to determine the "ok stop, let's do 180 and drive the other way now"... smile.gif

Wow, 450 meters, should have a good view of Vostok from there. I see a broad darker area at that distance, perhaps a slope to the south? If so on Wednesday Oppy may be at the top of a slight hill with a good view of Victoria.

Has anyone found any MOLA data for this area of Merdiani? If the plains do slope downwards at the point indicated in Alan's image that might offer an explanantion why Vostok and perhaps even Victoria Crater have been so hard to identify - it is quite strange that there is no obvious sign of Victoria Crater... Endurance Crater is still visible even in the rear hazcam images.

I seriously doubt there is any slope there, or it would've been visible on the horizon by now. The immediate area of Meridiani plain appears to be quite flat. I think it's just a darker windblown material deposited there...

I am still wondering what the dark feature NE from Vostok is.

I wonder, too. It seems to resemble the heatshield disturbance.

Oppy moves on during sol 385, after sol 384 during which nothing happened as far as I can see (there might still be a problem with back-to-back drives):

No features to see, but the dunes look different further on:

Maybe the larger dunes are causing the slightly darker region in the route map.

Rear Hazcam for the end of each sol

The PanCam images of the dunes on sol 385 were taken late in the day so the shadows make them especially prominent......

Oh, you are right, there was a change of scenery between 383 and 384. Both the front and back hazcams looked so similar, that I didn't realise it :-)

Are the drivers following the zigzag path set out in the "Road to Vostok" map or are they making a beeline due south of Endurance using the receding feature to help them keep their bearings? Just curious.

This reminds me so much of Snorkling off the coast of cuba.


I was just looking down from about 30 feet deep. And those ripples look so simular to what I saw.
