Dilo - nice polar and vertical views.
I'd like to suggest something. Will you make this pair of views for each panorama location on the descent down the hill, and then I will try to mosaic them into a map of the area, as an experiment? The projections might require a guess at the local slope to improve them. Phil -------------------- ... because the Solar System ain't gonna map itself.

A lot of small detail.
Thanks reckless, nice mosaic.  Nico -------------------- photographer, space imagery enthusiast, proud father and partner, and geek.

Hi everyone.
First time posting for me. Been reading UMSF for a while now and amazed by the work done by many of you. Can't go without a daily dose of Mars Rovers. Here's a small contribution from me. Not sure on the correct scale, but a feel for how Spirit may look at Comanche. Hope you enjoy. Astro0

Very nice, Astro0!
Not so distant from official simulations...

I will try to make further projections going back (some of them are already published). About slope, this is a foundamental issue: usually, I change orientation of my projections in order to have acircular far horizon in Polar version ("absolute" orientation) and roughly local slope for Vertical version (based on Rover aspect and/or tracks). -------------------- I always think before posting! - Marco -

jvandriel: Nice work. That's a perspective we don't often get to see.
Astro0: Thanks for that. The colors look pretty good to me, and it's always nice to see work by new people. -------------------- ...Tom

Nice mosaic. FWIW, here is the Navcam context, plus some L257 false-color of Ultreya/El Dorado:

Aloha!
I couldn't help noticing some 'reflection highlights' on the surface of Comanche where it has been brushed clear of dust. These white vertical line 'glints' appear in a number of the MI views released on Exploratorium on 21 and 22 December. I don't remember seeing them before on Mars rock surfaces, only on metallic parts of the MERs themselves. Does this suggest an unusual crystalline or metallic component of Comanche? Steverino didn't mention them in his latest epistle, though he did say the rock was "different". Has anyone seen them before? Can any geologists explain them?

Yep, them be sparklies. They are unusual here since the rock surfaces are either dusty or "sandblasted". Usually a strong reflection occurs from a fresh crystal face. I'll note that the reflective areas in these two images are locaed on the lighter "salt deposit" part of the rock and not on the (apparently) dusty side.
FWIW; we'll look more later... --Bill -------------------- |
