Crashed UFO found by Mars Reconnaissance Orbiter ?

After looking at a white balanced version I think I can see some "veins" from the ridge to the bottom, typical of sand dunes.

I think calling it a UFO is a bit of a stretch.
Looks more like some kind of geological formation to me.

Yeah, more accurately Unidentified Lie-ing (Laying?) Object, or Unidentified Geological Object for you skeptics.

Huge piece of asteroid leaving an eliptical crater. What looks like 2 sides of a disk is a deep furrow.
Perhaps low cosmic velocity relative to entry. A 'catch-up' grazing fall at a low angle. There are many examples somewhat like it all over Mars.
Like many asteroids, probably traveling with a few small pieces behind it that made the 3 smaller craters right over the original impact.

Dunes is probably a much better term than the one I used, which I chose because the link in the OP used it. Either way I think our minority view is correct I'm not so sure it is in a crater though - it seems more like the material is on top of the dune feature. There are numerous examples of slope instability in the area.

The Blackhawk landslide area in California has some similar features

Cross posting from the Martian pyramid thread, where one of them shows similar features:

Worm sign?

We have wormsign the likes of which even God has never seen.

Shock veins. Shallow faults caused by hypervelocity impact.
No need to post an example, as they are all around nearly every crater on the moon.

Also, in the SW portion of the scene, the parallel wall structures are part of the impact. They are outer crater waves frozen in time. An impact like this briefly turns the surface into behaving like a liquid, like a drop of water in a pool. The waves of material as they travel outward freeze in time as the materials instantly re-solidify.

There are 2 main rings in this crater, and a shallow wall structure is what would have been a third, but never really formed before it ran out of energy.
This is a great example of a low angle impact.

no - just another rock
