Astronomy Picture of the Day -- Jelly Donut Shaped Rock Appears on Mars
NASA ^ | January 29, 2014 | (see photo credit)

Posted on 01/30/2014 6:27:08 PM PST by SunkenCiv

Explanation: What if a rock that looked like a jelly donut suddenly appeared on Mars? That's just what happened in front of the robotic Opportunity rover currently exploring the red planet. The unexpectedly placed rock, pictured above, was imaged recently by Opportunity after not appearing in other images taken as recently as twelve Martian days (sols) before. Given the intriguing mystery, the leading explanation is somewhat tame -- the rock was recently scattered by one of the rover's tires. Even so, the rock's unusual light tones surrounding a red interior created interest in its composition -- as well as causing it to be nicknamed Jelly Donut. A subsequent chemical analysis showed the rock has twice the abundance of manganese than any other rock yet examined -- an unexpected clue that doesn't yet fit into humanity's understanding of the Martian geologic history. Opportunity, just passing its 10-year anniversary on Mars, continues to explore the Murray Ridge section of the rim of 22-kilometer wide Endeavor Crater.

I read today that a scientist is suing NASA (doesn’t make sense to me either) to get them to take better pictures of the rock. The suer says it’s not a rock, but spore growth. If you look, there IS something about the same shape and size in the first picture. Just strange.......

There’s a picture of a guy sticking his tongue out right below the jelly donut.

"...the leading explanation is somewhat tame -- the rock was recently scattered by one of the rover's tires."

It's an idiotic "explanation"! Why? Because anyone can see that the pebbles immediately surrounding the "rock" are still visible in the 'before' and 'after' pictures. If the rover "scattered" that rock, it would have 'collateral-scattering' surrounding the rock as well.

Nice paving stones, but somebody needs to get out the broom and do a little sweeping.

“Opportunity, just passing its ten year anniversary on Mars”

It’s a piece of birthday cake.

Not seeing the forest for the tree, or the rock. In the background, the ground appears to be made of flagstone.

If natural, it would mean the ground was worn off at a flat level.

If this was wind, one would expect the "grout" to be softer or harder than the stone, and thus leave irregular level.

But the ground is flat, indicating what, a glacier, an unnaturally prepared surface?

There is something in the “before” picture at the same location as the thing in the after picture, with a similar outline. What if the equivalent of a mushroom has popped up? This definitely deserves a closer look.

Yeah, why haven’t they taken a lot of pictures of this rock, aren’t they the least bit curious about it? Seems a little odd to me! Or is there something else going on here!

Looks to be the not so rare bird crap hitting the New Mexico Desert where this is being played out.

There is debris moved at about 6:30 and 1-foot from the teleported blue crab shell.
Two rocks in the left pic, moved in the right pic together.

Look up the explanation for “sailing stones” in deserts. Something similar here maybe, but wouldn’t have to be water freezing and thawing, Not sure of the actual temps where this is at on Mars.

Incredible - ten years and still operational. I wonder how many miles it has put on its odometer up there.

It’s this guy:

The late Arthur C. Clarke claimed that geological features seen from Martian orbit were “banyan trees”, and that too was nuttery.
