    NASA: Cassini Mission Enters Epic Endgame --"Flyby Poised to "Skim" Saturn's Rings" - The Daily Galaxy --Great Discoveries Channel
    http://www.dailygalaxy.com/...ission-enters-its-epic-endgame-flyby-poised-to-skim-saturns-rings.html

    NASA said its Cassini mission is set to begin on November 30 a daring set of "ring-grazing" orbits, during which it will fly closer to Saturns rings than it has since its 2004 arrival.

    Po uspesnem prijeti vsech dat z New Horizons o plutu se zaciname dovidat zajimave veci:

    Each time Pluto goes around the sun, a bit of nitrogen accumulates in the heart. And once enough ice has piled up, maybe a hundred meters thick, it starts to overwhelm the planet’s shape, which dictates the planet’s orientation. And if you have an excess of mass in one spot on the planet, it wants to go to the equator. Eventually, over millions of years, it will drag the whole planet over.

    ARCHIMEDES: radeji nez test na obezne draze bych radsi videl test ve vetsim meritku, v jine laboratori, na jine polokouli :)
    na obezne draze - to by bylo zas kecu stylem spatne zapocitali jak moc na to svitilo slunko/odraz mesice/cetnost skvrn na slunci

    KAERO: Jo, moje osobní sázka na reálnost efektu stoupla z 0,001 na 0,05. K tomu už se dlouho žádný "zázračný průlom" nepřiblížil - jsem zvědav, jestli/kdy někdo udělá nějaký ten poloavizovaný test na oběžné dráze.

    NASA's "Space Poop Challenge" is paying for your thoughts on upgrading its crappy system | Mic
    https://mic.com/...s-space-poop-challenge-is-paying-for-your-thoughts-on-upgrading-its-crappy-system

    The agency is currently soliciting entries in its aptly titled Space Poop Challenge, posted on the website HeroX, to "source a system that routes and collects human waste away from the body" for "fully-suited astronauts." What's more, it pays. The innovator with the winning design gets $30,000.

    Right now, astronauts use space toilets when they're out of their suits and diapers when they need to wear their spacesuits during launch and entry, but diapers are usually only worn for a matter of hours. They're also uncomfortable, and keeping waste next to your body for long periods of time can lead to irritation and infection.
