: akorát mi moc nedochází, jak by se s tím dalo manévrovat, nebo nedej bože brzdit. Protože dostat sondu k Marsu za 3 dny je sice boží, ale jak jí pak zbrzdit dost na to, aby na tom Marsu mohla přistát, nebo ho alespoň obíhat?

"It sounds like, you know, outer space-type music."
"You hear that? That whistling sound? Whooooooooo!"
"Well, that sure is weird music!"
"It's unbelievable! You know?"
"Shall we tell them about it?"
"I don't know. We ought to think about it."

Astro-H se úspěšně oddělila od nosiče. To vzali pěkným fofrem.

: Tam mají mikrofony nějak blízko rampy, jsem málem ohluchl jak odstartovala.
Let probíhá v pohodě, boostery už byly odhozeny. Vypadá to dobře.

Support grows for a return to ice giants Uranus and Neptune | Science News
https://www.sciencenews.org/article/support-grows-return-ice-giants-uranus-and-neptune
Thirty years ago, the Voyager 2 spacecraft tore past Uranus, then flew by Neptune less than four years later. These quick sojourns introduced scientists to two planets that had been vague blue splotches in their telescopes. In the years since, bigger and better instruments have teased out a bit more information and revealed a few surprises.
But there’s only so much planetary scientists can learn from a couple billion kilometers away. That’s why researchers in both the United States and Europe think it’s time to go back to Uranus or Neptune — the solar system’s “ice giants.” Unlike the show-stopping flyby of Pluto in 2015, a new mission to one of the blue worlds would have more time to take in the view.

A new hope for a microphone on Mars: Enhancing Mars 2020 science with sound | The Planetary Society
http://www.planetary.org/blogs/bruce-betts/2016/0215-mars-2020-microphone.html
When the Mars 2020 rover lands, we may finally hear the first audio recordings from the Martian surface. The Planetary Society has been working for decades to land a Mars Microphone, something that would add a second human sense to the amazing imagery we currently get, and would be very engaging and exciting for not only scientists, but also for the general public. Unfortunately, the only two such instruments to have launched suffered sad fates. The first Planetary Society Mars Microphone crashed with Mars Polar Lander. The second microphone to fly to Mars, on Phoenix, was never turned on because of the potential for an electronic problem. The payload of the ExoMars 2018 rover may include infrasound and pressure sensors that could produce sound-like recordings. In an abstract submitted to the 2016 Lunar and Planetary Science Conference (PDF), members of the Mars 2020 SuperCam team explain how including a microphone on their instrument could support their science -- and record sounds on Mars.

The Many Faces of Pluto and Charon | Pluto New Horizons
https://blogs.nasa.gov/pluto/2016/02/12/the-many-faces-of-pluto-and-charon/
The July 14, 2015 Pluto flyby gave us an initial look at one side of Pluto, with its iconic heart-shaped feature. But I’m interested in the full planetary perspective, finding the “other sides” of Pluto to be every bit as fascinating as the encounter hemisphere. We must remember that a flyby is a moment in time lasting a few hours. In contrast, Pluto and Charon each rotate about its axis every 6.4 Earth days. This means that when New Horizons flew through the Pluto system it captured one hemisphere of each body in incredible detail. What do we know about the “other sides” of Pluto and its largest moon?

Site of martian lakes might have been linked to ancient habitable environment | Astronomy.com
http://www.astronomy.com/...of-martian-lakes-might-have-been-linked-to-ancient-habitable-environment
These basins could have been episodically covered, perhaps during hundreds of millions of years, by lava and water lakes that were discharged from subsurface pressurized sources.
Groundwater circulation beneath a massive tectonic rift zone located along the flanks of some of the solar system's largest volcanic plateaus resulted in the formation more than 3 billion years ago of some of the deepest basins on Mars, according to a new paper by J. Alexis Palmero Rodriguez from the Planetary Science Institute.
