First interplanetary launch from the West Coast
All of NASA's interplanetary launches to date have been from Florida, in part because the physics of launching off the East Coast are better for journeys to other planets. But InSight will break the mold by launching from Vandenberg Air Force Base in California. It will be the first launch to another planet from the West Coast.

InSight will ride on top of a powerful Atlas V 401 rocket, which allows for a planetary trajectory to Mars from either coast. Vandenberg was ultimately chosen because it had more availability during InSight's launch period.

A whole new region will get to see an interplanetary launch when InSight rockets into the sky. In a clear, pre-dawn sky, the launch may be visible in California from Santa Maria to San Diego.

Možná blbá otázka - proč letí InSight na jih? Není to na Mars blíž přes východ?

"During the first 17 seconds of powered flight, the Atlas V will climb vertically above its launch pad. Then it will begin a pitch and yaw maneuver that will place it on a trajectory towards Earth’s south pole."

Pro nefacebookové: Dnes od 17:15 se na PřF UK koná přednáška profesora Schulze-Makucha nazvaná "Testing the Dry Limit of Life: From an Asphalt Desert to the Atacama Desert and Mars".

Anotace: Jak se studuje život v nejsušších místech na Zemi a co nám jeho rozličné adaptace na tamní drsné podmínky mohou napovědět o šancích na život na jiných tělesech či metodách pátrání po životě či jeho chemických pozůstatcích například na Marsu? Kde bychom měli hledat život mimo Zemi? Tyto a další otázky nastíní profesor Schulze-Makuch, astrobiolog a náš host z Berlínské technické univerzity.
Mezi jeho nedávné studie patří právě výzkum mikroorganismů v půdních profilech atacamské pouště a zjištění, že míra osídlení se odvíjí od celé řady podmínek jako depozice materiálu, seismická aktivita, salinita či četnost mlh. Tento výzkum nejen rozvíjí naše znalosti o životě v hraničních podmínkách na Zemi, ale má i uplatnění ve vytipování vhodných míst, kam posílat kosmické sondy na Marsu. (Přednáška proběhne v angličtině bez tlumočení.)

Dirk Schulze-Makuch (nar. 1964) je profesor v Centru pro astronomii a astrofyziku na Berlínské technické univerzitě. Publikoval více než stovku vědeckých článků a je autorem či spoluautorem devíti knih týkajících se oboru astrobiologie, od učebnic přes popularizační knihy až po jeden science fiction román. Vystudoval geologii a zabýval se například transportem mikroorganismů a chemických látek v pozemní vodě a rolí organismů v geochemických cyklech. V současné době se zabývá zejména extremofilním životem a možnostmi geobiochemických cyklů na jiných tělesech než Země. Podílí se také na několika konceptech kosmických misí.

BTW, před pár dny mu vyšel článek k tomuto tématu: http://www.pnas.org/content/early/2018/02/20/1714341115

Tak teprva teď trochu cejtím cestovní horečku...

Pls, nemáte někdo zkušenosti s tím, jak je to s externí baterkou na tablet/mobil na letišti? Dnes jsem
koupil novou, pač stará už dosluhuje, ale mám trochu obavu, že mě s tím nepustí na palubu...

Some black holes erase your past | Berkeley News
http://news.berkeley.edu/2018/02/20/some-black-holes-erase-your-past/

In the real world, your past uniquely determines your future. If a physicist knows how the universe starts out, she can calculate its future for all time and all space.

But a UC Berkeley mathematician has found some types of black holes in which this law breaks down. If someone were to venture into one of these relatively benign black holes,
they could survive, but their past would be obliterated and they could have an infinite number of possible futures.

ALMA Deepens Mystery about the relation between Supermassive Black Holes and their Host Galaxies | ALMA
http://www.almaobservatory.org/...relation-between-supermassive-black-holes-and-their-host-galaxies/

Using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe an active galaxy with a strong ionized gas outflow from the galactic center,
astronomers have obtained a result making astronomers even more puzzled: an unambiguous detection of carbon monoxide (CO) gas associated with the galactic disk.
However, they have also found that the CO gas which settles in the galaxy is not affected by the strong ionized gas outflow launched from the galactic center.

Astronomers reveal secrets of most distant supernova ever detected | UoP News
http://uopnews.port.ac.uk/.../20/astronomers-reveal-secrets-of-most-distant-supernova-ever-detected/

An international team of astronomers, including Professor Bob Nichol from the University of Portsmouth, has confirmed the discovery of the most
distant supernova ever detected – a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the Universe itself.

The exploding star, named DES16C2nm, was detected by the Dark Energy Survey (DES), an international collaboration to map several hundred million
galaxies in order to find out more about dark energy – the mysterious force believed to be causing the accelerated expansion of the Universe.

As detailed in a new study published in The Astrophysical Journal, light from the event has taken 10.5 billion years to reach Earth, making it
the oldest supernova ever discovered and studied. The Universe itself is thought to be 13.8 billion years old.

The planet Mars has fascinated scientists for over a century. Today, it is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth’s.
But evidence suggests that in the early history of our solar system, Mars had an ocean’s worth of water. NASA’s James Webb Space Telescope will study Mars to learn
more about the planet’s transition from wet to dry, and what that means about its past and present habitability.

Obrázek, který pořídil fotovyslanec ESO Petr Horálek, ukazuje planetu Venuši jasně zářící nad observatoří ESO Paranal v Chile. Zobrazený dalekohled je
pomocný dalekohled VLT (AT1), který už je otevřený a během soumraku se připravuje na pozorování nočního nebe. To se zatím halí do odstínů modré a oranžové.

In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs – and offer an extraterrestrial source for mineral mining.

But for researcher Nicholas Hud, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system.
Having that information gives scientists the starting point they need to reconstruct the complex pathway that got life started on Earth.

Director of the NSF-NASA Center for Chemical Evolution at the Georgia Institute of Technology, Hud says finding molecules in asteroids provides the strongest evidence
that such compounds were present on the Earth before life formed. Knowing what molecules were present helps establish the initial conditions that led to the formation
of amino acids and related compounds that, in turn, came together to form peptides, small protein-like molecules that may have kicked off life on this planet.

Hurá!!

NASA’s next planet-hunting mission has arrived in Florida to begin preparations for launch. The Transiting Exoplanet Survey Satellite
(TESS) is scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station nearby NASA’s Kennedy Space Center in
Florida no earlier than April 16, pending range approval. TESS was delivered Feb. 12 aboard a truck from Orbital ATK in Dulles, Virginia,
where it spent 2017 being assembled and tested. Over the next month, the spacecraft will be prepped for launch at Kennedy’s Payload
Hazardous Servicing Facility (PHSF).
