They are back to taking pictures for the Bonestell Pan.


4. What EDRs did we request?

Expected EDRs by sequence number and image type:

Aah - your bigger image shows that your two splat features have a much bigger cousin to the north, not far below the south rim of Thira. I would agree that something has caused the impact craters of a certain age in this region to have floors that are cemented in some way and thus erosion resistant. I wouldn't like to guess whether the cementing process is melting per se or something else.

There seems to be some related information at THEMIS website:

"Lobes of a smooth material appear to have flowed, perhaps as water-rich sediments or molten lava, across an older, knobby landscape. The older surface is spotted by its pits, knobs, buttes, and mesas. The knobs may have been eroded by winds into fluted shapes called yardangs that trend northwest-southeast."

"The material (south of the Columbia Hills) partly resembles the rough, knobby terrain located on the southeast floor of Gusev. If it has the same origin, then here THEMIS may be looking through a "window" opened by erosion that gives a view down to the older knobby material that is better exposed to the east."
I presume this knobby material is the one we're talking about?

I've tried to had some perspective to the area (nothing that accurate...):

But it changed my point of view about some features, for instance, the oversized Home Plate (03) seems from this angle to be another mesa-like as others surrounding it, the splat like feature to the left (01) looks like the mentioned cemented crater floor, the one to right (04)...don't what what to think of it, seems to be higher than its surroundings, is this consistent with an old crater floor (EDITED: Now looking better it looks like there's a wall to the right that could be a remnant of a crater...)?
Another feature caught my attention (02), it appears to my eyes as some sort of cone but it is probably just a optical illusion...


EDITED: It wouldn't hurt asking SS if an HiRISE image of this area is planned...
"We currently have all the HiRISE images we need to plan Spirit's operations for the coming martian year."

Why?! Why?!

Huumm..."for the current martian year"?...Huumm...
