There's something weird going on beyond Neptune - A mysterious object has been discovered with an inexplicable orbit.
California-based Jet Propulsion Laboratory (JPL) has been central to the US missile and rocket development and operations for decades, and from the beginning that technology's success rested on a corps of expert mathematicians, people known as computers. And from the beginning they were all women, in a time when such opportunities were few and far between. You can find pictures of them, but names have not been well-recorded ... until now. Nathalia Holt found many of those women and wrote about their experiences in her book, Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars. [more inside]

Remember the prototype lunar rover that was believed to be scrapped but was recovered by a junkyard owner? It just failed to sell at auction, and could be yours if you have an amount of money more than $30000 burning a hole in your pocket.
RED 4K Video of Colorful Liquid in Space. "Once again, astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama." [Via]
The New York Times is reporting that NASA is about to announce the discovery of "definitive signs of liquid water on the surface of present-day Mars."
In 2011, Ardbeg, a prominent Scotch whisky distiller, sent vials of its whisky to the International Space Station to mature. Those vials have been returned to Earth and subjected to taste tests alongside samples of the same whisky matured at Ardbeg's distillery. [more inside]

Your name could be on Mars in the next several months. You've already paid for it, so you might as well go. In March 2016, NASA is launching its Insight lander, which will be the first Mars mission to probe beneath the surface of the Red Planet and explore its interior in-depth. (In-depth, get it? Nevermind) They're offering to micro-etch the name of any Earthling who wishes on the lander. Here's where to sign up. [more inside]
“In 1999, two Canadian astrophysicists, Stéphane Dumas and Yvan Dutil, composed and sent a message into space. The message was composed of twenty-three pages of bitmapped data, and was sent from the RT-70 radio telescope in Yevpatoria, Ukraine, as part of a set of messages called Cosmic Call.” [more inside]
The joke was funny because this was just a tiny, two-year college, with no engineering program. Getting into space was the last thing on the minds of these students; they were just trying to escape poverty. Next thing they knew, NASA was calling them up.
can life survive for billions of years longer than the expected timeline on Earth? as scientists continue to discover older and older solar systems & galaxies, it’s likely that before long we’ll find an ancient planet in a habitable zone. knowing if life is possible on this exoplanet would have immense implications for habitability and the development of ancient life according to researcher Tiago Campante's paper "An Ancient Extrasolar System with Five Sub-Earth-Size Planets". this animation starts by showing us Kepler's field-of-view in the direction of the constellations Cygnus and Lyra, and then we're taken to the vicinity of the Kepler-444 planetary system, located some 117 light years away.
"On July 14, NASA’s New Horizons spacecraft will fly past Pluto, offering the first close-up look at that small, distant world and its largest moon, Charon. These denizens of the outer solar system will be transformed from poorly seen, hazy bodies to tangible worlds with distinct features." Who gets to name those features? You do. Via Bad Astronomy.
One hundred years ago today, on March 3, 1915, a Naval Appropriations Bill was passed through Congress and signed by president Woodrow Wilson. A small rider was attached to the bill and went through the process almost completely unnoticed. That rider legislated the formation of the National Advisory Committee for Aeronautics. [more inside]
From the initial 202,586 applicants, 100 hopefuls have been selected to proceed to the next round of the Mars One Astronaut Selection Process. The final 100 chosen come from around the world, with 39 from the Americas, 31 from Europe, 16 from Asia, 7 from Africa, and 7 from Oceania. A total of 40 candidates will eventually be chosen to take part in a training programme and live in a copy of the Mars outpost on Earth. [more inside]
The station is called Junction Gate, a colony seed that never fully blossomed. You see plans for mines, habitat modules, research facilities, and shipyards.
We know space is big, but trying to understand how big is tricky. Say you stare up at the sky and identify stars and constellations in a virtual planetarium, you can't quite fathom how far away all those stars are (previously, twice). Even if you could change your point of view and zoom around in space to really see 100,000 nearby stars (autoplaying ambient music, and there are actually 119,617 stars mapped in 3D space), it's still difficult to get a sense of scale. There's this static image of various items mapped on a log scale from XKCD (previously), and an interactive horizontal journey down from the sun to the heliosphere with OMG Space (previously). You can get a bit more dynamic with this interactive Scale of the Universe webpage (also available in with some variants, if you want the sequel [ previously, twice], the swirly, gravity-optional version that takes some time to load, and the wrong version [previously]), but that's just for the scale of objects, not of space itself. If you want to get spaced out, imagine if If the Moon Were Only 1 Pixel, and travel from there (previously). This past March, BBC Future put out a really big infographic, which also takes a moment to load, but then you can see all sorts of things, from the surface of Earth out to the edge of our solar system.
You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?Dr. Peter Watts is no stranger to MetaFilter. But look past his sardonic nuptials, heartbreaking eulogies, and agonizing run-ins with fascists (and fasciitis) and you'll find one of the most brilliant, compelling, and disquieting science fiction authors at work today. A marine biologist skilled at deep background research, his acclaimed 2006 novel Blindsight [full text] -- a cerebral "first contact" tale led by a diverse crew of bleeding-edge post-humans -- is diamond-hard and deeply horrifying, wringing profound existential dread from such abstruse concepts as the Chinese Room, the Philosophical Zombie, Chernoff faces, and the myriad quirks and blind spots that haunt the human mind. But Blindsight's last, shattering insight is not the end of the story -- along with crew/ship/"Firefall" notes, a blackly funny in-universe lecture on resurrecting sociopathic vampirism (PDF - prev.), and a rigorously-cited (and spoiler-laden) reference section, tomorrow will see the release of

Storm Chasing on Saturn with Cassini [viz. cf.] - "The sun is slowly rising over Saturn's north pole, exposing an immense six-sided hurricane. The storm, big enough to swallow four Earths, was first spotted by the Voyager missions in the early 1980s. [Cassini] will be passing directly over the north pole with its cameras pointing down later this month." (previously 1,2)

Theoretically sound model for metallic carbon found. Researchers from Peking University, Virginia Commonwealth University and Shanghai Institute of Technical Physics employed state-of-the-art theoretical methods to show that it is possible to manipulate carbon to form a three-dimensional metallic phase with interlocking hexagons. “Unlike high-pressure techniques that require three terapascals of pressure to make carbon metallic, the studied structures are stable at ambient conditions and may be synthesized using benzene or polyacenes molecules." The new metallic carbon structures may have important applications in lightweight metals for space applications, catalysis and in devices showing negative differential resistance or superconductivity. The research is supported by grants from China and the US Department of Energy.

After nearly 5000 launches, we've put a lot of objects in space. Amongst them are around half a million pieces of debris, generated by explosions, breakups and collisions (previously). With speeds of up to 15 km/s, even tiny fragments can cause major damage and the creation of further debris. The Kessler Syndrome describes a situation where the cascade of collisions creates an exponential increase in the amount of debris, leading to a potentially impassable artificial belt in LEO lasting for generations.

How often does a great story dominate the headlines, only to be dropped from the news cycle? How often do journalists tell us of a looming danger or important discovery – only to move quickly to the next new thing? What really happened? How did these events change us? And what are the lingering consequences that may affect our society to this day? These are the questions we are answering at Retro Report, an innovative documentary news organization launched in 2013 as a timely online counterweight to today’s 24/7 news cycle. Combining documentary techniques with shoe-leather reporting, we peel back the layers of some of the most perplexing news stories of our past with the goal of encouraging the public to think more critically about current events and the media in ~10 minute segments.

Skylab, NASA's budget space station, launched 40 years ago today. Designed as an orbiting optical laboratory, she served as a cold war weapon, underwent an historic salvage job, and was the site of America's first space mutiny before landing hard in Australia while waiting for the Space Shuttle to be invented.
Last fall, the Canadian Space Agency asked students to design a simple science experiment that could be performed in space, using items already available aboard the International Space Station. Today, Commander Chris Hadfield conducted the winner for its designers: two tenth grade students, Kendra Lemke and Meredith Faulkner, in a live feed to their school in Fall River, Nova Scotia. And now, we finally have an answer to the age-old question, What Happens When You Wring Out A Washcloth In Space? [more inside]
