Mysterious Appearing Mars Rock new
      #6322917 - 01/19/14 07:57 PM

Dave, others,

Do you know if anyone has done an overlap-of-images of Opportunity Sol 3540 and Sol 3528 to see if there are, in addition to the new rock, scorings/fragments/modifications of what was already in 3528? Can you do an overlap? If we could then we might get some idea of direction and causation; wheel-spin-out, meteorite ejecta, rock fell from some nearby rock face.

Otto

Look at the two photos cross-eyed, so that you merge the images. (It didn't tell me anything.)

I looked at both images for a good half hour. I didn't see a single pebble or score mark on the ground. It does seem odd that the rock managed to land so perfectly that it didn't disturb the ground.

I do wnder what the other side of the rock looks like. And the composition makes it a bit more interesting.

I looked too; I saw a few differences, but they all looked like they were probably just lighting effects. If that rock had been thrown from an impact somewhere, it seems like it would have disturbed the site more. And I don't think Opportunity moves fast enough to fling rocks out of its way. (Plus, hadn't it been stationary for a while before those pictures were taken?)

It's very mysterious, especially since I don't particularly think it was placed there deliberately.
Maybe it "just growed?"

Can anyone think of a similar event arising with any of the other manned or unmanned craft in the past?

According to Squyres, its composition is like nothing they've seen before. If you look at the terrain that Opportunity has been exploring, it's a pretty consistent plain of wide-spread sedimentary deposits, even where craters have penetrated to some depth. An object kicked up by Opportunity's wheels wouldn't be this chemically distinctive. I'm more and more leaning towards ejecta debris from a relatively distant impact.

I think that it has been thrown up by one of these...

Martian dust devils

If you read the abbreviated logs on the public website, sometime between the two photos, they had an 'unexpected dust clearing event' for the solar panels, with an associated dramatic increase in power production.

That actually bodes well for a theory that uses martian weather as the force that deposited the new stone. It would be very interesting to see photos of what was happening around the rover during the 'dust clearing event', and get a feel for just how violent it really was. It could also bode well for a theory of a nearby impact, which caused a rather high wind, possibly shock wave of some sort.

I dunno; I don't think the air on Mars is thick enough to move a rock. It takes a pretty severe dust storm to even get small gravel to move by saltation. I'll be very surprised it this ends up being what happened.

I'd still like to see some navcam pictures of the site of the turning maneuver before and after the turn, to see if the target rock was there before and missing after (implying a tiddlywink effect).

with the atmosphere being so thin i doubt it was the wind too.

does anyone know if this rock looks like other martian rocks nearby?

Mysterious rock found by Mars rover....

A jelly dough nut size rock that mysteriously appeared in front of the rover.

According to Steve Squyres "It's like nothing we've ever seen before".

The main argument in favor of it being carried by dust devils is that its shape involves a large surface area, and its composition being high in sulphates means its density is rather low. Even so, it seems a bit of a stretch.

So does the ejecta debris, actually. And so does anything else I can possibly imagine. It's extraordinary, whatever the explanation.

Has anyone seen the newest color images of it. Its got a lot of white, ice like colors to it, mixed with the color of mars dust. It has even a hollow ish shape to it. Like it was a part of the rover was covered in ice (the end of a metal tube or camera or something) then the part warmed up or moved and the formation fell off.

In the new color pictures it looks like a dusty piece of ice. Would explain how it just appearing there. Can you imagine the odds of a meteor hitting mars and either part of it or its ejected material landing right next to the rover? Must be astronomical.

You would think the experts would have come to that conclusion if this was it. I guess it must not be just ice that fell off the rover, they would have thought of that right?

Anyway that's what it looks like to me.

Does the rover have any CO2 tanks or chemicals of some kind that could have caused ice to form on the end of one if its parts? Then it falls off and kind of compresses into this rock like looking blob? You know, not water ice but some other frozen chemistry?
