Mont Sharp by the Mastcam100 at Sol45 is finaly over.

The classical "raw" stitched one, with links to the various resolutions :



And the "postcard" one with an extended sky. I had to work on a 3/4 reduced sized version because of the weight of this kind of picture.

blink.gif ...wow. Speaking of conglomerates! That nice smooth-looking pebble stuck right of center in it is most intriguing.

That, my friend, is a thing of beauty. I envy the people who will one day stand on the spot where Curiosity took those images and see Mt Sharp in all its glory. But you've shown it to me, so thank you! smile.gif

Thank you so much Stu smile.gif

I think there will be some rest for my computer. This is the largest panoramic I ever made ! 42 519 Χ 2505 pixels and 34.3 Mo for the full resolution !

This the Sol45 Mastcam100 pan, showing a full 180° of landscape. Sadly, I just can't visualise the full res on my computer (a black area appear on the right part, at 2/3 from the left…).

Impressive work Ant! The sol 45 postcard of Aeolis Mons aka Mount Sharp is just beautiful.

I have only a small one to add - sol 52, 34mm vertical pan:

A couple of suggestions for Beaulieu on Earth (only the one in Canada's north works in this context) - but I was asking where it is on Mars. Which place, which sol, which image - can anyone locate it?

how close is the match between Jake and Phobos or Deimos?

I would presume not very. Phobos & Deimos are probably captured carbonaceous asteroids. They may have some splatter on their surfaces from Martian impact debris, but given that Jake is igneous in origin & seemingly may have had to form in the presence of water I think it's unlikely that it's originally from either of those bodies.

If I understand correctly (which I may not as I am a microbiologist tongue.gif ) there is confusion about Jake and water from the teleconference. Jake did not form in the presence of surface or liquid water, but rather at depth where rocks and minerals are hydrated and there is water dissolved in magma. If the pressure is released too quickly, you get an explosion, like at Mt St. Helens. Jake was the last rock to crystalize/solidify out of the cooling magma---the less soluble minerals crystalized out earlier. The fact that Jake was not a frothy rock (or pumice) indicates that it solidified at a high enough pressure (deep enough) to keep the water in the magma phase. Some day I will have to actually study rocks--hope I'm not too far off.

Beautiful post cards Ant. And here's one in stereo. Sunset at Gale ~ Sol 50 ~ MC34 & MC100 anaglyph pairing.

That's not what I heard. People were trying to read too much into the composition. We have a rock whose composition is different in certain interesting ways from Mars meteorites or basalts seen by Opportunity or Spirit. It is still a basalt. If you look at a library of basalts from Earth environments, it is most similar to a particular kind of basalt found in certain environments at ocean islands or in eclogites. On Earth, that implies that a variety of different origins are possible. On Mars, who knows? The environments could've been similar to the ones that made similar-composition rocks on Earth, but they could also have been different. With only a single rock that is not in place, it's way too early to say anything beyond the fact that it has a so far unique composition.

A version of the sol 50 view with Mastcam M-100 and M-34 images to fill in the top. Thanks mcaplinger for the tip on color adjustment in the Images and Cameras thread.
