    of a time-lapse video of that dune action? I bet it's fascinating to watch.

      I think they spotted the movement from orbital images over a period of time. Would make a great time-lapse, for sure.

          Thank you, ratfox

          That was every bit as cool as I thought it would be - had no idea about the "moaning" of the sands. Now we just need to politely ask Sir David to narrate a similar NASA vid of the Martian dunes.

        Wow. Commentards and Regtards queuing up to watch sand blown by the wind.

        I'm planning to do some painting soon, if you'd like to come round and watch that dry?

    Bah!

    Stunning images indeed, but rather less inspiring science going on. Think how much time this "sand grain sorting" project would get in the press if we had a team of humans on planet.

    *sigh*

    Gotta dream.

      Personally the images themselves are worth it for me. I'd have been even happier if they'd sent a probe to a more photogenic place such as the Valles Marinas or the Helles Basin even if the science was slightly less interesting (though I doubt it would be). Geology is all well and good, but its not the reason most people are interested in planetary exploration.

      Re: Bah!

      I'd rather we didn't, to be honest, unless there's a serious immediate benefit to doing so. It's very expensive to get there, it's basically going to be shots of a lot of rocks, and most importantly whoever is sent will die out there. Satellites and robots are increasingly cheaper and easier to land.

      When there's a chance of the crew surviving, and not having decades knocked off their life expectancy it'll be a better idea.

        I'm glad we have people like you, making sure we look after other people's money and well being, keeping us firmly grounded.

        I imagine you do a lot of thinking about the children too?

        1. BinkyTheMagicPaperclip

          Re: Bah!

          odfo dear. There is a difference between legislating against something that might, in a blue moon, possibly affect a particularly unfortunate and stupid child, and something that is definitely extremely expensive, will certainly take money away from other spacecraft, and almost certainly won't allow the astronauts to return home.

          I'd like more spacecraft on comets, planetary moons, solar exploration - it's gathered new and exciting science across many environments, rather than limiting it to Mars.

        If it's a choice of dying forty years from now in a nursing home, dribbling and pissing myself, or dying in twenty years* on a far off world, after spending my time being a pioneer and living the adventure of a lifetime; Well, I know which I'd choose!

        *Shit, I'd still go, even if I lived less than ten.

    Curious

    I'd have thought the much lower gravity would have allowed much steeper gradients to form with sand until a landslide occurs but that doesn't seem to be the case. Unless I'm getting confused with the perspective.

      Re: Curious

      and it's exactly why actually going places and doing stuff is so good for science. Either the science underpinning your expectations is wrong or incomplete (in which case we need to know more), or your application of current science wrong or incomplete (which is also good, since mistakes can be highly informative).

      Re: Curious

      "I'd have thought the much lower gravity would have allowed much steeper gradients to form"

      Nope. It is the gravity that creates the forces that lock the particles together. More gravity means the particles lock together more strongly and thus less prone to landslides.

      To an extent you can observe this by looking at sand in water where the buoyancy created by the water reduces the weight of the sand and allows it to flow more easily. Of course the water itself has lubricating properties too, so it's not an apples-to-apples comparison.

    Wheel Damage

    I recall reading, some time ago, that Curiosity's wheels didn't seem to be holding up as well as planned, and seemed to be receiving a lot more damage than expected, but that middle wheel looks totalled.

      looking at a hi re copy, you are correct, it looks pretty munted

      Hasn't it been operating 2+ years-ish longer than expected?

        It's a heavy old machine too.

        It's all good though, information from those wheels will be used to make the next wheels.

    Almost as exciting ....

    ... as watching grass grow.

    On the other hand, if Curiosity spots that, it would be worth a photo.

      An interesting simulation of moving dunes is Zhang's sandpile model. http://dare.ubvu.vu.nl/handle/1871/11714.

    horizontal cracks

    What's with the horizontal cracks in the dune face? Something must be helping the particles stick/clump together otherwise the cracks would immediately fill in.
