It was a short drive to the SW on sol 124 to reach a nice outcrop.

Appears as though they reversed back over a rock they drove over at the end of the sol 127 drive?

Was running up over the boulder intentional or was it a mistake? It seems to be a risky maneuver.

If you run over it with one wheel it might be better to back up than to go ahead, halving the number of other wheels having to climb the rock.

Here is a circular view and a close-up of the area.

The autonomous drive seemed comfortable with climbing the rock, but leery of the combination of the raised rock between the wheels and the configuration of the end of the sand drift.

Thanks Phil, really enjoy your circular views
Do you think the rover has crossed into the next map quadrangle at the Sol 129 drive?
It looks close on the map I have, but it's not really high enough resolution to be sure
Click to view attachment

Right about on the boundary, I would say. I hope we start getting some more names of features soon. A map is naked without names!

Phil

Agreed fully re feature names, Now that the most of the hardware and the majority of the instruments have been fully commissioned, I hope that the team members will soon be in a position where they can share a few mission updates.

Good news for us remote followers of the mission...

"Blog Coming Soon
Mission team members are getting ready to share their stories with you as they explore Jezero crater with the help of the Mars Perseverance rover. "


Mission team - thank you for this. We understand how crazy everything must have been for the last 130 sols, but this will be greatly appreciated!


Phil

Here is the context for the SuperCam image from sol 130.
The purpose of the fierce action with the wheels on sol 129 was presumably to excavate parts of rocks which have not been subjected to weathering for millions of years.

Another possible reason for the wheel action on sol 129: the intention to get a fresh rock surface by driving over a rock with fractures like this one and breaking it (which apparently did not happen).

Driving on sol 134: Here's a pair of NavCam tiles looking back at the tracks and some of the extensive boulder field that the rover has picked its way through to continue it drive to the next major science waypoint close to the helicopters current location. The mosaic has been very roughly processed, but it should provide a taste of the terrain behind the rover at the end of the drive at site 5 / drive 894, and maybe help pinpoint its location.

We came about 90 m south - map update coning soon.

Sol 134 vista with enhanced colors and a slightly enlarged anaglyph

Is it my imagination, or are all the big rocks angled in the same direction?

A few billion years of prevailing wind erosion will do that.

Indeed, although I don't see them as nice lithographic limestone. I see them as fine clastics deposited in a lacustrine or lagoonal environment, before the serious deltaic sediments started in.

--Bill

As with tau's image of the sol 134 vista, I suspect that we are seeing the eroded remnants of the extrusive lava flow.
