Re: Golfball crater spotted by MGS

An object this big would have made a much larger crater than this unless it were hollow.

Any thoughts?

Re: Golfball crater spotted by MGS

looks like a puddle of sand in the crater, not the object that made the crater. you can make out some dune crests. i see many odd craters like this, some other ones have puddling with islands and peninsulas the sand being so black it looks like water from orbit, i heard some scientists comment they think it shops evidence of water puddling, not merely sand blowing around. i cant remember the url of the image but if i find it ill return to this thread and post it.

i think the 3D effect seen on the golfball here (making it look half-buried) is illusory due to dark sand area creating a false "terminator line" that happens to apporoximately match the sol shadow angle.

i dodnt find any other examples like this crater so its definately unusual, thats a good directory to browse at random, lots of intersting pics. here's abunch of other great pictures from that directory:
