    Pluto’s Mysterious, Floating Hills
    http://www.nasa.gov/feature/pluto-s-mysterious-floating-hills

    The nitrogen ice glaciers on Pluto appear to carry an intriguing cargo: numerous, isolated hills that may be fragments of water ice from Pluto’s surrounding uplands. These hills individually measure one to several miles or kilometers across, according to images and data from NASA’s New Horizons mission.

    The hills, which are in the vast ice plain informally named Sputnik Planum within Pluto’s ‘heart,’ are likely miniature versions of the larger, jumbled mountains on Sputnik Planum’s western border. They are yet another example of Pluto’s fascinating and abundant geological activity.

    Because water ice is less dense than nitrogen-dominated ice, scientists believe these water ice hills are floating in a sea of frozen nitrogen and move over time like icebergs in Earth’s Arctic Ocean. The hills are likely fragments of the rugged uplands that have broken away and are being carried by the nitrogen glaciers into Sputnik Planum. ‘Chains’ of the drifting hills are formed along the flow paths of the glaciers. When the hills enter the cellular terrain of central Sputnik Planum, they become subject to the convective motions of the nitrogen ice, and are pushed to the edges of the cells, where the hills cluster in groups reaching up to 12 miles (20 kilometers) across.

    Cassini Solstice Mission: Saturn's Rings: Less than Meets the Eye?
    http://saturn.jpl.nasa.gov/news/cassinifeatures/feature20160202/

    Fast Facts:

    * Researchers "weighed" the central parts of Saturn's most massive ring for the first time.
    * The results confirm that more opaque areas in the rings do not necessarily contain more material.
    * Research on the mass of Saturn's rings has important implications for their age.

    Fun with a new data set: Chang'e 3 lander and Yutu rover camera data | The Planetary Society
    http://www.planetary.org/blogs/emily-lakdawalla/2016/01281656-fun-with-a-new-data-set-change.html

    So, space fans, without further ado, here, for the first time in a format easily accessible to the public, are hundreds and hundreds of science-quality images from the Chang'e 3 lander and Yutu rover. I don't usually host entire data sets (PDS-formatted and all) but I made an exception in this case because the Chinese website is a bit challenging to use.

    * Chang'e 3 Yutu rover panoramic camera (PCAM) data released as of January 20, 2016
    * Chang'e 3 lander terrain camera data (TCAM) released as of January 20, 2016

    And here are just a few of the goodies contained therein. You may want to keep Phil Stooke's landing site map and Yutu route map handy for reference as you look through these!

    Mysterious Martian "Cauliflower" May Be the Latest Hint of Alien Life | Science | Smithsonian
    http://www.smithsonianmag.com/...martian-cauliflower-may-be-latest-hint-alien-life-180957981/?no-ist

    In 2008, scientists announced that NASA’s Spirit rover had discovered deposits of a mineral called opaline silica inside Mars's Gusev crater. That on its own is not as noteworthy as the silica’s shape: Its outer layers are covered in tiny nodules that look like heads of cauliflower sprouting from the red dirt.

    No one knows for sure how those shapes—affectionately called “micro-digitate silica protrusions”—formed. But based on recent discoveries in a Chilean desert, Steven Ruff and Jack Farmer, both of Arizona State University in Tempe, think the silica might have been sculpted by microbes. At a meeting of the American Geophysical Union in December, they made the case that these weird minerals might be our best targets for identifying evidence of past life on Mars.

    CLUMP: loni se hirise na sezonni zmeny tehle skvrnicich oblasti docela soustredil a radu z nich vyfotil treba trikrat s ruznymi casovymi odstupy. prisel jsem na to nahodou pri prochazeni katalogu snimku, nevsimnul jsem si, ze by to nekde avizovali. at uz je to cokoliv, snad k tomu driv nebo pozdeji vydaji nejakou studii nebo aspon clanek se srovnanim.

    srovnejte napriklad ruzne faze tehle dun (snimek v predchozim prispevku patri myslim mezi tyhle dva):

    Life in the dark dune spots of Mars: a testable hypothesis - ResearchGate
    http://www.researchgate.net/...n/252158441_Life_in_the_dark_dune_spots_of_Mars_a_testable_hypothesis

    ABSTRACT: This chapter presents one of the very rare exobiological hypotheses. The main thesis is that there could be life in the dark dune spots (DDSs) of the southern polar region of Mars, at latitudes between –60° and –80°. The spots have a characteristic annual morphological cycle and it is suspected that liquid water forms in them every year. We propose that a consortium of simple organisms (similar to bacteria) comes to life each year, driven by sunlight absorbed by the photosynthetic members of the consortium. A crucial feature of the proposed habitat is that life processes take place only under the cover of water ice/frost/snow. By the time this frost disappears from the dunes, the putative microbes, named Mars surface organisms (MSOs) must revert to a dormant state. The hypothesis has been worked out in considerable detail, it has not been convincingly refuted so far, and it is certainly testable by available scientific methods. We survey some of the history of, the logic behind, the testable predictions of, and the main challenges to the DDS-MSO hypothesis.
