    SUMAC: Pominu technické výdobytky časovače a samospouště, a
    odpovím ti poněkud profláklým gifem (někdy loni či předloni zaplavil sociálky).
    Název zněl nějak takto: "Hergot, to se na ISS dělaj parádně selfíčka v mikrogravitaci" :))

    High-resolution images of Pluto taken by NASA’s New Horizons spacecraft just before closest approach on July 14, 2015, are the sharpest images to date of Pluto’s varied terrain—revealing details down to scales of 270 meters. In this 75-mile (120-kilometer) section of the taken from the larger, high-resolution mosaic above, the textured surface of the plain surrounds two isolated ice mountains.

    High-resolution images of Pluto taken by NASA’s New Horizons spacecraft just before closest approach on July 14, 2015, reveal features as small as 270 yards (250 meters) across, from craters to faulted mountain blocks, to the textured surface of the vast basin informally called Sputnik Planum. Enhanced color has been added from the global color image. This image is about 330 miles (530 kilometers) across. For optimal viewing, zoom in on the image on a larger screen.

    Perplexing Pluto: New ‘Snakeskin’ Image and More from New Horizons
    http://www.nasa.gov/feature/perplexing-pluto-new-snakeskin-image-and-more-from-new-horizons



    In this extended color image of Pluto taken by NASA’s New Horizons spacecraft, rounded and bizarrely textured mountains, informally named the Tartarus Dorsa, rise up along Pluto’s day-night terminator and show intricate but puzzling patterns of blue-gray ridges and reddish material in between. This view, roughly 330 miles (530 kilometers) across, combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC) on July 14, 2015, and resolves details and colors on scales as small as 0.8 miles (1.3 kilometers).

    Mars' Mysterious Dark Streaks Spur Exploration Debate
    http://www.space.com/30618-mars-water-streaks-rsl-mystery.html

    The dark, fingerlike features that creep down steep Martian slopes in warm weather continue to puzzle scientists.

    These "recurring slope lineae" (RSL), which have been spotted by NASA's Mars Reconnaissance Orbiter (MRO) at low and middle latitudes on the Red Planet, fade during cooler months but come back again annually at nearly the same locations over multiple Martian years.

    Scientists continue to debate the true nature of the RSL phenomenon; no guess as to what they are and why they occur yet satisfies all observations. And just how RSL sites should be explored generates spirited debate, as evidenced by the discussions that emerged during the second Mars 2020 Landing Site Workshop, which was held last month in Monrovia, California.

    Curiosity update, sols 1073-1107: Driving toward dunes, distracted by haloes | The Planetary Society
    http://www.planetary.org/blogs/emily-lakdawalla/2015/09181704-curiosity-update-sols-1073-1107.html



    The damage to the wheels has changed only slightly since sol 708.



    Haloes in the Stimson unit, Curiosity sols 1083-1094 - As Curiosity drove across the Stimson unit, the rover repeatedly encountered fractures in the rock that were surrounded by bright haloes of unknown cause. The photos were taken on sol 1083 (top left), 1087 (top right), 1093 (lower left), and 1094) lower right) by the Navcam.

    ARCHIMEDES: Dnes se na to někdo psal, s dovolením zduplikuji odpověď,
    pač se mi to nechce psát 2x. Takže kdyby to někde ztrácelo smysl, je to vytržením z kontextu... :)

    Nikdo v ESA nad Philae neláme a nezlomil hůl!
    Jen to není tak jednoduché a při spojení hraje roli více faktorů. Rosetta musí být "na správném místě ve správný čas", co znamená být nad oblastí 0-55 stupňů severně od rovníku komet. jádra, a na to má jen pár desítek minut zhruba 2x za jeden pozemský den.
    Maximální vzdálenost od jádra pro zachycení slabého signálu Philae je nějakých 200 km, takže teď na to můžeme úplně zapomenout. Ale na konci října se Rosetta znovu přiblíží, a pokusy o kontakt budou pokračovat. Mají na to čas zhruba do konce roku, celou tu dobu se může Philae probrat. Pak už to bude horší: bude ubývat sluníčka i teploty.
    Navíc aby mohly R-P komunikovat, musí obsluha Rosetty aktivovat jeden přídavný elektrický systém, a navíc jej nastavit do "vyhledávacího" režimu. Až pak začne sonda vysílat signál na povrch jádra. Pokud bude Philae aspoň chvilku aktivní, je nastaven tak, aby na tento signál začal automaticky odpovídat. Ten systém už je nějakou dobu inaktivní, pač je sonda daleko od jádra (teď nějakých 500 km?), a ještě pár týdnů bude dokonce 3x dál.
    Do toho obsluhu trápily problémy na jednom z příjmačů Philae, který byl kvůli zkratu vypnut palubním počítačem landeru. Fakt to není jednoduché...
