See the rover's wheel tracks disappearing off to the East
Assembled from 2 NavCam tiles after the drive on sol 1556. JPL have not yet released the drive data or the map, but it looks like a long drive down slope to the East and further away from the crater rim.
I'll post the details and map as soon as I see them
If I'm lining up my features right, it would appear they went SW or WSW, at least for part of the drive, not veering very far from the heading they initially took downrim.
I wondered if they would stick around at the last site and sniff what look to be more spherules a bit longer. They even took some night-time imagery of the things, and they don't break out the LED that often, aside from the abrasion patches. From what little I know of impactite materials over on Luna, you'd really want to return more of these to Earth. I am really not sure we captured too many in Sample 29. They have some funky stories to tell, no doubt completely different from the ones that impact beads on Earth and Luna would tell you.
Update - The JSON's were just released, see new post
