Another weird Mars pic YAY!

I usually wouldn't start a Mars anomaly thread as there are many
already, but this one is baffling scientists everywhere! (j/k).

Anyway, what gets me is how clean the bottom of the 'crater' is.
Weird.

... although, now that I'm reviewing it, I suppose the interior layer
could have settled afterward. Still cool imo.

The true origination of the Antlion...

I don't find this image as baffling as were the early images from the Mars orbiter that seemingly showed multiple, transparent tubes with curved support members. The tubes seemed to wind their way along subsurface valley areas. I believe that they were explained away by NASA.

Still, even if natural formations of some sort, because of their peculiarities, they would be of interest even today. I wonder why we don't see them anymore. Do you suppose....

To me, this looks like a collapsed pit, probably originating from a pocket of CO2 underground.

I assume you mean these:



I wasn't happy with the explanation either, but I guess
I'll accept it for now (until we roll up in a rover and find
out otherwise).

NASA: apparent tubes are dunes inside crevasse/fissures.
(Note- there are better pics that do like like dunes. Ah well.)

Nice closeup!

The bottom looks clean enough to eat off!

what made a hole like taht i cant say except it was no meteor .
as for the ice co2 or what ever simple the hole was formed afterwards teh ice formed at the bottom .
Ps www.google.com...

teh most likely explanation is something like this

How on earth (or on mars) can people confuse dune-filled troughs with "glass tubes"?

Probably because of ice.

Except it's not ice. Those are sand dunes formed by wind.

A closeup:


These "transverse aeolian ripples" are quite common on Mars.

Doesn't look so much like glass tubes now, does it?

a reply to: wildespace

Sure does... if I squint really hard.

Thanks for the closeup!

Yes well, I did mean frozen dunes, these pictures are missing the original extreme shine.

An interesting object sticking up on there to the right.

Uh... did anyone here ever play Total Annihilation?

Tell me that doesn't look like a map from that game.
