back to article Geoboffins spot hundreds of ghost dunes on Mars

Mars was once covered in hundreds of giant dunes as big as the US Capitol Building billions of years ago, according to new research. A pair of scientists from the University of Washington have discovered more than 300 crescent-shaped structures wedged into the eastern side of Hellas Planitia, an impact crater measuring over 2, …

    Just a matter of time until they find spice as well..

      whelp... Going by the source, there should be a high concentration in the larva channels mentioned in the article...

        If this is the hole that the larva made, I would hate to meet the adult form

          Wouldn't worry, they died off a long thyme ago.

    That's no dune

    Compared to a lot on Earth they're certainly not 'giants' - the larger deserts of the world have dunes hundreds of meters high. Maybe these are giants on the Martian dune scale?

    As it's a photograph, perhaps ninjaturtle is right - it was taken as the sandworms were breaking the surface and another shot is needed to confirm movement ...

      And how big is it now? In standard Reg units please? Bigger or smaller than Drumpf's ego? Bigger or smaller than Drumpf's manservant hands?

      All the current Capitol buildings atoms were the same size as now, just arranged differently.

        I'd suggest that since some may be decay products from radioactive elements, then some at least will be smaller now than they were back then.

      The Capitol Building existed on Mars billions of years ago ?!?

        And is that a short billion or a long billion?

          "And is that a short billion or a long billion?"

          Don't be silly! It's a scientific article: they used the metric billion!

          that would be METRIC BILLIONS

    We found a rock!!!

    I hate need for sponsored/hyped content and even here, research. "We found a rock" becomes, "we found a rock that may have rolled near the possibility of *life*, it may have possibly coughed near a *climate change*, and then quantum/cloud storage/bitconnect!!!!"

    Ok, I exaggerate, and in no means suggest the data or research is suspect, but the write up (paper at times and media mostly) is as full of buzzwords and made meaningless by both social pressures and beancounters/marketing. :(

    Packing list for first manned Mars mission:

    - bucket and spade...

    - "kiss me quick" hat....

    I'm sure you can already find a stick of rock (might not have "Mars" through the middle of it).

      I would love to deal with it for you, just how big a budget have you got, and are you planning on coming along as well?

      Nowt? Really? Then what has Curiosity been rolling over all these years?

    We could understand the scale if only we could understand the units used in the article. Were these parking meters or electricity meters?

      The dunes at Noctis Labyrinthus are about 285.71429 linguine, 0.28925748 brontosaurus high, the ones at Hellas basin are about 535.71429 linguine, 0.54235778 brontosaurus high.
