New Horizons Returns Best Images of Pluto's Moons Hydra and Nix

An anonymous reader writes: Over the weekend, the New Horizons probe sent back more data from Pluto, including two of the best images we'll get of its small moons Nix and Hydra. Nix measures about 42km long by 36km wide, and has a large reddish spot on it. The resolution allows us to see features about 3km across. Hydra is slightly bigger, and the pictures were taken with a different instrument, so resolution is a bit better. "Although the overall surface color of Nix is neutral grey in the image, the newfound region has a distinct red tint. Hints of a bull's-eye pattern lead scientists to speculate that the reddish region is a crater. ... Meanwhile, the sharpest image yet received from New Horizons of Pluto's satellite Hydra shows that its irregular shape resembles the state of Michigan. ...Although the overall surface color of Nix is neutral grey in the image, the newfound region has a distinct red tint. Hints of a bull's-eye pattern lead scientists to speculate that the reddish region is a crater." Images have been taken of Styx and Kerberos, the most recently discovered moons of Pluto, but they won't be transmitted back for a while, yet. NASA has also released an image of a mountain range inside Pluto's heart-shaped region.

    What the fuck has happened to Slashdot?

    Here we have a great submission about a scientific topic that has been on the front page for some time.

    But there are only 7 comments so far, not including this one.

    Of those 7 comments, 5 of them [that's over 70% of them!] have been modded down to -1 already.

    None of them are high quality comments, but none of them should be at -1, either.

    They are actually about this topic, which is more than we can say about the remaining two comments.

    One accuses Pluto of being a transsexual astral body, yet that comment is at +2.

    The other is one of those pathetic "You are all cows. MOOOOOOO!" comments that we've seen so many of lately. It is at 0.

    I suspect that it is one or more people working for Slashdot who go through and give the plain -1 downmods, with no indicator of why.

    This happens in every topic.

    Valuable comments end up at -1 right away.

    Idiotic comments don't.

    It is like the moderating system has been turned upside down, so that good comments get downmodded and bad comments stay the same or even get upmodded!

    It was never like this before.

    If a submission like this was posted even just a couple of years ago, there would be good discussion about it.

    There would not have been this rabid and instantaneous downmodding of good comments.

    I never had to browse at -1 just to read high quality comments that were incorrectly modded down!

  8. Pluto's Glacier by amightywind · · Score: 0

    The rate at which pictures are being released by the project are pathetic. I don't want to hear how low the data rate is from Pluto. Paranoid scientists are witholding dozens or hundreds of them to keep from being scoped. Spunik Planum is a glacier. Of what material, who knows? CO, N2, or some weird mixture. You can see that the region covers the darker terrain by the many embayment relationships at the meeting of terrains at its edge. The patterned ground is also a giveaway, but who can explain the large size of the patterns? What is the dark stuff? Organic gunk, not unlike light crude oil or LNG at fantastically low temperature. In processed approach images you can see the path that gas sublimating from the glacier takes as it sublimates and migrates to the pluto dark side from the sub solar latitude. It faintly stains the terrain. My guess is that glaciers like Sputnik Planum accumulate on the dark side during Pluto's pronounced winters, as the erode from the light side. They seem to be 100's of meters if not kilometers thick. The complex seasons produced by Pluto's elliptical orbit and high inclination surely disrupt the surface asymmetrically. Pluto is in southern summer and just passed perihelion. The south cap should be near its minimum extent. Pluto is a freaky place. Release more pictures greedy scientists!

      The plaid patterns on the surface you're talking about are JPG compression artifacts. NH will spend the next several weeks sending JPGs. Once we have a "safe copy" in lossy format, it will start transmitting lossless RAW images. This will take months. Such a strategy assures maximum data return if a mechanical failure terminates the mission.

      To be real it's the transmission speed that is causing the delays. We have not even learned that Sharon caused that gash at slow speeds when the wandering comet became a moon and in the process knocked Pluto out of circular orbit. (Theory).

      Do we have the results of what the "ice" actually is?
