Cassini Returns Photos of Hyperion

imipak writes "The Cassini Saturn probe has captured the previously unseen northern polar region of Saturn's moon Hyperion. Its weirdly eroded surface looks like nothing else in the solar system seen so far, demonstrating once again that when it comes to planetary exploration, "expect the unexpected" is more than just glib advice from the Hitch-hiker's Guide!"

The "buried" object itself seems to be very sharply defined with straight lines, as opposed to the more "natural" landscape around it.

      I blew it up considerably in Photoshop and increased the contrast to see details better. There are a number of smaller craters directly in the path of the line. If it were a rock impact, to my (non-astrophysicist/geologist) eye it looks like it behaved like a skipping stone - There are some bigger craters near where the top of the image cuts off the line, and about halfway along there's a pair on opposite sides of what appears to be a hill, as if it were skating along, used the hill as a jump, landed, and continued its movement.

      Actually there are a ton of reasons for such a surface.

      1) Its by Saturn which has a massive gravitational pull. This causes Saturn to pull in a lot of comets, asteroids, and dust. Thus Saturn gets hit with a lot more debris then the planets in the inner solar system. This would also increase the risk of the moons getting hit with this debris as well and therefore will have more impacts then that of the planets and moons in which we know.
      2) Saturn has rings filled with debris. So if the moon ever happened to swing into these rings it would go through hundreds if not thousands of impacts. That could have very well created the surface that you see. This could have happened at any time in the moons history and so is a very likely cause.
      3) The moon could have some sort geological processes that are responsible for such a surface, however thats very unlikely.

      Personally I would put my bet on number 2 cause it makes the most sense. If the moon went through on of Saturns rings especially when the rings might have just formed there would have been a lot of collisions leaving the surface scarred like you see in the picture.

  61. JPEG vs TIFF by The+Master+Control+P · · Score: 2, Interesting

    I took a close look at the high-res pictures they offer in TIFF (3MB) and JPEG (120K) format. Even though the jpg contains 1/25th as much information as the tiff, it still looked decent up close. When I tried turning the contrast way up (100) the tiff was far better up close (jpeg turned to gray mush), but at hi con both looked similar at 100%. The tif seemed to have more vibrant colors.

    What I'm trying to ask is, does anyone else notice a major difference between the two without using the GIMP @ 7 or 8X zoom?

  64. Possible Interpretation by lorelorn · · Score: 5, Informative
    If you look at the main facing side of Hyperion (in the image that is actually of Hyperion) what you are seeing is part of a very old impact crater.

    You can see the raised part in the centre, around which is part of the old crater wall.

    Note the crater wall is significantly brighter than the surrounds - this is exposed materials, mainly water ice to judge from the brightness.

    The other thing to note is that the crater is incomplete, and is itself riddled with craters, both the centre and the crater walls. This tells us that the large crater is very old. How old I would leave to an expert of the Saturnian system, who would no more about impact frequencies than me.

    Hyperion is interesting in that it is the largest irregular body in the solar system. Anything larger (and many smaller objects) are pulled into a spherical shape by their own gravity. Hyperion is not that much smaller than Enceladus, and is of a similar make-up (frozen H2O) yet these object are very different.

    I would hypothesise that a large impact has sheared off part of Hyperion- that's why the large crater is incomplete - the rest is gone, possibly to become part of the ring material but I don't know what the timing of that blast was.

    The very strange not-really-craters next to the very large impact crater I would say were outgassing artefacts, not any type of impact crater. Basically the heat from the large impact caused volatiles to rocket out of Hyperion, leaving those sort of "exit valve" formations.

  67. Funny you should mention Mars by Markus+Registrada · · Score: 1
    "Like thing else in the solar system"?

    This stuff looks a great deal like features found all over Mars, just enormously more concentrated, and steeper. (Notice particularly the flat-bottomed craters on hillsides and on the right side of the image.) Of course the mechanisms normally proposed for the Martian features ("collapse pits") are inconceivable applied to identical features on Hyperion. That doesn't reduce the objective similarity, of course, but it makes those mechanisms much less plausible for the Martian features.

    The notion that the straight lines on Tethys are fault lines is nothing short of ludicrous. Any fractures it has (a) would have no reason to be straight, and (b) wouldn't selectively attract meteorite craters centered along them. Carving by oblique impacts is even worse; butter would not slice out that cleanly, they wouldn't follow up and down hills with occasional wide/deep spots, and there's still the problem of round craters preferentially centered on them.

    The only plausible source of geometrically straight lines on a body like this is geometric: rotation past an external reference.

    The electromagnetic environment around Saturn is certainly busy enough to make electric arcing a mechanism worth investigating. That would explain the craters along the lines -- each records a spike of current flow -- and the oddly-shaped excavation at the end. The length of each line, coupled with the (approximate) rotation rate, reveals the duration of the arcing, the rate of excavation, and (thereby) the approximate current involved.
