Google Maps Now Lets You Explore Your Local Planets and Moons ( 8

Google has added three planets and nine moons to Google Maps. "The heavenly bodies include Saturn moons Dione, Enceladus, Iapetus, Mimas, Rhea and Titan, and Jupiter moons Europa, Ganymede and Io," reports CNET. "Google also added dwarf-planets Pluto and Ceres and full-planet Venus." From the report: Once inside Google Maps for planets, you can spin the space objects around, get more information on their place names and zoom in for a closer look. The new worlds are possible thanks to imagery from NASA and the European Space Agency. NASA's dearly departed Cassini spacecraft sent back a treasure trove of views of Saturn's moons. If you have a few moments to spare, fire up a browser, go to your current location on Google Maps, enter satellite mode and hit the zoom-out button until you've left the planet and are "floating" in space. A list of available planets and moons pops up on the side and you're off on your space adventure.

Astronomers Strike Gravitational Gold In Colliding Neutron Stars ( 80

For the first time, scientists have caught two neutron stars in the act of colliding, revealing that these strange smash-ups are the source of heavy elements such as gold and platinum. From a report: The discovery, announced today at a news conference and in scientific reports written by some 3,500 researchers, solves a long-standing mystery about the origin of these heavy elements -- which are found in everything from wedding rings to cellphones to nuclear weapons. It's also a dramatic demonstration of how astrophysics is being transformed by humanity's newfound ability to detect gravitational waves, ripples in the fabric of space-time that are created when massive objects spin around each other and finally collide. "It's so beautiful. It's so beautiful it makes me want to cry. It's the fulfillment of dozens, hundreds, thousands of people's efforts, but it's also the fulfillment of an idea suddenly becoming real," says Peter Saulson of Syracuse University, who has spent more than three decades working on the detection of gravitational waves. Albert Einstein predicted the existence of these ripples more than a century ago, but scientists didn't manage to detect them until 2015. Until now, they'd made only four such detections, and each time the distortions in space-time were caused by the collision of two black holes. That bizarre phenomenon, however, can't normally be seen by telescopes that look for light. Neutron stars, by contrast, spew out visible cosmic fireworks when they come together. These incredibly dense stars are as small as cities like New York and yet have more mass than our sun.

Elon Musk Teases Reddit With Bad Answers About BFR Rocket ( 97

Long-time Slashdot reader Rei writes: On Saturday evening, Elon Musk took questions in a Reddit AMA (Ask-Me-Anything) concerning SpaceX's new design for the BFR (Big F* Rocket). But unlike the 2016 IAC conference where many audience questions seemed to be trolling Musk, this time the tables were turned. Asked why Raptor thrust was reduced from 300 tons to 170, Musk replied, "We chickened out." He responded to a statement about landing on the moon by quoting Bob the Builder, while responding to a user's suggestion about caching internet data from Mars by writing simply "Nerd." A question as to whether BFR autogenous pressurization would be heat-exchanger based, Musk replied that they planned to utilize the Incendio spell from Harry Potter -- helpfully providing a Wikipedia link for the spell.

A technical question about the lack of a tail? "Tails are lame." A question about why the number of landing legs was increased from 3 to 4? "Because 4." After one Redditor observed "This is one bizarre AMA so far," Musk replied "Just wait..." While Musk ultimately did follow up some of the trolling with some actual responses, the overall event could be best described as "surreal".

To be fair, Musk provided some serious answers. (And his final comment ended with "Great questions nk!!") But one Redditor suggested Musk's stranger answers were like a threat, along the lines of "Just wait. It will get way more bizarre than that. Let me finish my whiskey."

Musk replied, "How did you know? I am actually drinking whiskey right now. Really."

8.5-Ton Chinese Space Station Will Crash To Earth In a Few Months ( 101

dryriver writes: China launched a space laboratory named Tiangong 1 into orbit in 2011. The space laboratory was supposed to become a symbol of China's ambitious bid to become a space superpower. After two years in space, Tiangong 1 started experiencing technical failure. Last year Chinese officials confirmed that the space laboratory had to be scrapped. The 8.5 ton heavy space laboratory has begun its descent towards Earth and is expected to crash back to Earth within the next few months.

Most of the laboratory is expected to burn up in earth's atmosphere, but experts believe that pieces as heavy as 100 kilograms (220 pounds) may survive re-entry and impact earth's surface. Nobody will be able to predict with any precision where those chunks of space laboratory will land on Earth until a few hours before re-entry occurs. The chance that anyone would be harmed by Tiangong-1's debris is considered unlikely.

When NASA's SkyLab fell to earth in 1979, an Australian town fined them $400 -- for littering.

Why China is Winning the Clean Energy Race ( 212

An anonymous reader shares a report: U.S. politicians have been warning for years that America couldn't let China win the clean energy race. That's exactly what has happened, with the trends most stark in electric cars, solar and nuclear energy. Why it matters: Building for the last decade, these trends have accelerated in the last couple of years. Politicians and business leaders said America's dominance in this space would bring jobs to the U.S. and security to our clean-energy resources, and now both of those goals are at risk. Why China is doing this: It needs to literally energize its 1.4 billion people, both how they travel and how they power their homes. Its leadership feels compelled to do it in a cleaner way than the U.S. did. Air pollution is at dangerously high levels across many of China's cities. People are seeing and feeling health repercussions of China's dependence on fossil fuel-fired cars and power plants in an acute way. Traditional air pollution, not climate change, is a big driver.

Scientists Discover Ring Around Dwarf Planet Haumea Beyond Neptune 49

A ring has been discovered around one of the dwarf planets that orbits the outer reaches of the solar system. Until now, ring-like structures had only been found around the four outer planets -- Jupiter, Saturn, Uranus and Neptune. The Guardian reports: "In 2014 we discovered that a very small body in the Centaurs region [an area of small celestial bodies between the asteroid belt and Neptune] had a ring and at that time it seemed to be a very weird thing," explained Dr Jose Ortiz, whose group at the Instituto de Astrofisica de Andalucia in Granada made the discovery described in the journal Nature. "We didn't expect to find a ring around Haumea, but we were not too surprised either." Haumea was recognized by the International Astronomical Union in 2008 and is one of five dwarf planets, alongside Pluto, Ceres, Eris and Makemake. They are located beyond Neptune -- 50 times farther away from the sun than Earth. Haumea, named after the Hawaiian goddess of childbirth, is unusual because of its elongated shape, comparable to a rugby ball, and its rapid rotation, spinning around once every 3.9 hours. Its diameter is approximately a third of the size of Earth's moon.

SpaceX Successfully Landed the 12th Falcon 9 Rocket of 2017 ( 117

Shortly after launching from Cape Canaveral, Florida, SpaceX's Falcon 9 rocket successfully landed on one of the company's drone ships in the ocean. "It marks the 12th time SpaceX has successfully landed the first stage of a Falcon 9 rocket this year, the 18th overall, and the second this week," reports The Verge. "It was also the third time that the company has successfully launched and landed a rocket that had already flown." From the report: The vehicle for this mission has flown before: once back in February, when it lofted cargo to the International Space Station and then landed at SpaceX's ground-based Landing Zone 1. Going up on this flight is a hybrid satellite that will be used by two companies, SES and EchoStar. Called EchoStar 105/SES-11, the satellite will sit in a high orbit 22,000 miles above Earth, providing high-definition broadcasts to the U.S. and other parts of North America. While this is the first time EchoStar is flying a payload on a used Falcon 9, this is familiar territory for SES. The company's SES-10 satellite went up on the first "re-flight" in March. And SES has made it very clear that it is eager to fly its satellites on previously flown boosters.

How Does Microsoft Avoid Being the Next IBM? ( 223

An anonymous reader quotes a report from Ars Technica: For fans of the platform, the official confirmation that Windows on phones isn't under active development any longer -- security bugs will be fixed, but new features and new hardware aren't on the cards -- isn't a big surprise. This is merely a sad acknowledgement of what we already knew. Last week, Microsoft also announced that it was getting out of the music business, signaling another small retreat from the consumer space. It's tempting to shrug and dismiss each of these instances, pointing to Microsoft's continued enterprise strength as evidence that the company's position remains strong. And certainly, sticking to the enterprise space is a thing that Microsoft could do. Become the next IBM: a stable, dull, multibillion dollar business. But IBM probably doesn't want to be IBM right now -- it has had five straight years of falling revenue amid declining relevance of its legacy businesses -- and Microsoft probably shouldn't want to be the next IBM, either. Today, Microsoft is facing similar pressures -- Windows, though still critical, isn't as essential to people's lives as it was a decade ago -- and risks a similar fate. Dropping consumer ambitions and retreating to the enterprise is a mistake. Microsoft's failure in smartphones is bad for Windows, and it's bad for Microsoft's position in the enterprise as a whole.

Why Is 'Blade Runner' the Title of 'Blade Runner'? ( 220

Why is Blade Runner called Blade Runner? Though the viewer is told in the opening text of Ridley Scott's 1982 original that "special Blade Runner units" hunt renegade replicants -- and though the term "Blade Runner" is applied to Harrison Ford's Rick Deckard a few times in the film -- we're never given an explanation of where the proper noun comes from. The novel upon which Blade Runner was based, Philip K. Dick's Do Androids Dream of Electric Sheep?, offers no clues either.

Tokyo Preparing For Floods 'Beyond Anything We've Seen' ( 98

In the face of an era of extreme weather brought on by climate change, global cities are working to improve their defenses. The New York Times reports (Warning: may be paywalled; alternative source) of Tokyo's $2 billion underground anti-flood system that consists of tunnels that divert water away from the region's most vulnerable floodplains. The city is "preparing for flooding beyond anything we've seen," says Kuniharu Abe, head of the underground site. From the report: But even in Tokyo, the onset of more frequent and intense storms has forced officials to question whether the region's protections are strong enough, a concern that has become more urgent as the city prepares to host the 2020 Olympic Games. Across Japan, rainfall measuring more than 2 inches an hour has increased 30 percent over the past three decades, the Japan Meteorological Agency estimates. The frequency of rainfall of more than 3 inches an hour has jumped 70 percent. The agency attributes the increase of these intense rains to global warming, heralding a new era in a country that is among the world's wettest, with a language that has dozens of words for rain. [...]

Experts have also questioned the wisdom of erecting more concrete defenses in a country that has dammed most of its major river systems and fortified entire shorelines with breakwaters and concrete blocks. Some of these protections, they say, only encourage development in regions that could still be vulnerable to future flooding. In eastern Saitama, where the Kasukabe facility has done the most to reduce floods, local industry has flourished; the region has successfully attracted several large e-commerce distribution centers and a new shopping mall. Still, the Kasukabe operation remains a critical part of Tokyo's defenses, say officials at Japan's Land Ministry, which runs the site. Five vertical, underground cisterns, almost 250 feet deep, take in stormwater from four rivers north of Tokyo. A series of tunnels connect the cisterns to a vast tank, larger than a soccer field, with ceilings held up by 60-foot pillars that give the space a temple-like feel. From that tank, industrial pumps discharge the floodwater at a controlled pace into the Edo river, a larger river system that flushes the water into Tokyo Bay.


Half the Universe's Missing Matter Has Just Been Finally Found ( 247

An anonymous reader shares a report: The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe -- protons, neutrons and electrons -- unaccounted for by previous observations of stars, galaxies and other bright objects in space. You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far. Two separate teams found the missing matter -- made of particles called baryons rather than dark matter -- linking galaxies together through filaments of hot, diffuse gas. "The missing baryon problem is solved," says Hideki Tanimura at the Institute of Space Astrophysics in Orsay, France, leader of one of the groups. The other team was led by Anna de Graaff at the University of Edinburgh, UK. Because the gas is so tenuous and not quite hot enough for X-ray telescopes to pick up, nobody had been able to see it before.

'Blade Runner 2049' Isn't the Movie Denis Villeneuve Wanted to Make ( 263

Readers share a Motherboard article: There are seemingly two inescapable realities for big-budget filmmakers in 2017: you have to use existing intellectual property and you must provide spectacle that can lure massive domestic and foreign audiences to the the theater. It seemed that Denis Villeneuve chose wisely when he selected the IP that he would ride into the mainstream. [...] There is much to admire, but as a whole, Blade Runner 2049 works best as a case for why filmmakers like Villeneuve should be given big budgets to try out new concepts rather than retread what's come before them. Just like Arrival was at its best when we saw the elegance of how the space ship and the aliens within it actually functioned, this version of Blade Runner shines when we get to watch how Villeneuve's dystopia operates. Moments of technical brilliance small and large are at the soul of this film. Whether you're watching the creation of robot memories, the execution of an air strike from an effortless, detached distance, or even something as simple as a stroll through a hall of records, the mechanics of this world are jaw-dropping. Ryan Gosling (K) wisely opts for a muted, brooding performance, allowing the world to steal the show while still illustrating the burden of living in it. Even with all of this technical brilliance on display (the costumes, sound, and special effects are brilliant), the baggage of the original film's mythology weighs down Blade Runner 2049. The most burdensome baggage for Villeneuve to carry, sadly, is the Blade Runner story itself.

SpaceX's Mars Vision Puts Pressure on NASA's Manned Exploration Programs ( 142

An anonymous reader shares a report: Entrepreneur Elon Musk's announcement late last month accelerating plans for manned flights to Mars ratchets up political and public relations pressure on NASA's efforts to reach the same goal. With Musk publicly laying out a much faster schedule than NASA -- while contending his vision is less expensive and could be financed primarily with private funds -- a debate unlike any before is shaping up over the direction of U.S. space policy. Industry officials and space experts consider the proposal by Musk's Space Exploration to land people on the red planet around the middle of the next decade extremely optimistic. Some supporters concede the deadline appears ambitious even for reaching the moon, while Musk himself acknowledged some of his projected dates are merely "aspirational." But the National Aeronautics and Space Administration doesn't envision getting astronauts to Mars until at least a decade later, a timeline NASA is finding increasingly hard to defend in the face of criticism that it is too slow.

Linux Now Has its First Open Source RISC-V Processor ( 161

"SiFive has declared that 2018 will be the year of RISC V Linux processors," writes Design News. An anonymous reader quotes their report: When it released its first open-source system on a chip, the Freeform Everywhere 310, last year, Silicon Valley startup SiFive was aiming to push the RISC-V architecture to transform the hardware industry in the way that Linux transformed the software industry. Now the company has delivered further on that promise with the release of the U54-MC Coreplex, the first RISC-V-based chip that supports Linux, Unix, and FreeBSD... This latest development has RISC-V enthusiasts particularly excited because now it opens up a whole new world of use cases for the architecture and paves the way for RISC-V processors to compete with ARM cores and similar offerings in the enterprise and consumer space...

"The U54 Coreplexes are great for companies looking to build SoC's around RISC-V," Andrew Waterman co-founder and chief engineer at SiFive, as well as the one of the co-creators of RISC-V, told Design News. "The forthcoming silicon is going to enable much better software development for RISC-V." Waterman said that, while SiFive had developed low-level software such as compilers for RISC-V the company really hopes that the open-source community will be taking a much broader role going forward and really pushing the technology forward. "No matter how big of a role we would want to have we can't make a dent," Waterman said. "But what we can do is make sure the army of engineers out there are empowered."


Astronaut Scott Kelly Describes One Year In Space -- And Its After Effects ( 200

53-year-old astronaut Scott Kelly shared a dramatic excerpt from his new book Endurance: A Year in Space, A Lifetime of Discovery in the Brisbane Times, describing his first 48 hours back on earth and what he'd learned on the mission: I push back from the table and struggle to stand up, feeling like a very old man getting out of a recliner... I make it to my bedroom without incident and close the door behind me. Every part of my body hurts. All my joints and all of my muscles are protesting the crushing pressure of gravity. I'm also nauseated, though I haven't thrown up... When I'm finally vertical, the pain in my legs is awful, and on top of that pain I feel a sensation that's even more alarming: it feels as though all the blood in my body is rushing to my legs, like the sensation of the blood rushing to your head when you do a handstand, but in reverse. I can feel the tissue in my legs swelling... Normally if I woke up feeling like this, I would go to the emergency room. But no one at the hospital will have seen symptoms of having been in space for a year...

Our space agencies won't be able to push out farther into space, to a destination like Mars, until we can learn more about how to strengthen the weakest links in the chain that make space flight possible: the human body and mind... [V]ery little is known about what occurs after month six. The symptoms may get precipitously worse in the ninth month, for instance, or they may level off. We don't know, and there is only one way to find out... On my previous flight to the space station, a mission of 159 days, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained and shrank the walls of my heart. More troubling, I experienced problems with my vision, as many other astronauts had. I had been exposed to more than 30 times the radiation of a person on Earth, equivalent to about 10 chest X-rays every day. This exposure would increase my risk of a fatal cancer for the rest of my life.

Kelly says the Space Station crew performed more than 400 experiments, though about 25% of his time went to tracking his own health. "If we could learn how to counteract the devastating impact of bone loss in microgravity, the solutions could well be applied to osteoporosis and other bone diseases. If we could learn how to keep our hearts healthy in space, that knowledge could be useful on Earth." Kelly says he felt better a few months after returning to earth, adding "It's gratifying to see how curious people are about my mission, how much children instinctively feel the excitement and wonder of space flight, and how many people think, as I do, that Mars is the next step... I know now that if we decide to do it, we can."

Google Accused of Racketeering. Lawsuit Claims 'Pattern' Of Trade Secret Thefts ( 153

schwit1 quotes the Mercury News: In an explosive new allegation, a renowned architect has accused Google of racketeering, saying in a lawsuit the company has a pattern of stealing trade secrets from people it first invites to collaborate. Architect Eli Attia spent 50 years developing what his lawsuit calls "game-changing new technology" for building construction. Google in 2010 struck a deal to work with him on commercializing it as software, and Attia moved with his family from New York to Palo Alto to focus on the initiative, code-named "Project Genie." The project was undertaken in Google's secretive "Google X" unit for experimental "moonshots."

But then Google and its co-founders Larry Page and Sergey Brin "plotted to squeeze Attia out of the project" and pretended to kill it but used Attia's technology to "surreptitiously" spin off Project Genie into a new company, according to the lawsuit... This week, a judge in Santa Clara County Superior Court approved the addition of racketeering claims to the lawsuit originally filed in 2014. Attia's legal team uncovered six other incidents in which Google had engaged in a "substantially similar fact pattern of misappropriation of trade secrets" from other people or companies, according to a July 25 legal filing from Attia.

Wired reported yesterday that Project Loon -- also a Google X project -- "is embroiled in a lawsuit with Space Data, a small company accusing Alphabet of patent infringement, misappropriation of trade secrets, and breach of contract following a failed acquisition bid."

The lawyer for the racketeering suit complains Google can deploy a "virtually unlimited budget to fight these things in court."

Anticipating Samsung's AMOLED Mixed Reality Headset ( 36

Eloking quotes Windows Central: At an event in San Francisco, HoloLens inventor Alex Kipman outlined the future of Windows Mixed Reality, which Redmond seems to believe is the future of computing. Whether or not it is remains to be seen, but either way, there will be no shortage of Windows Mixed Reality headsets this holiday season, with perhaps the most compelling option coming from Samsung.

The $500 Samsung HMD Odyssey sports dual AMOLED eye displays, complete with a 110-degree field of view. This could potentially make a huge difference in the quality of the Windows Mixed Reality experience for two reasons. First, AMOLED displays can generate deeper blacks and more vibrant colors than your average OLED or LCD screen. Second, all other Windows Mixed Reality headsets we've seen have a 95-degree FoV. The Samsung headset will be more immersive because there will be less dead space in your peripheral vision.

The headset -- which comes with motion controllers -- is expected to launch in one month.

The World's Oldest Scientific Satellite is Still in Orbit ( 80

walterbyrd writes: Nearly 60 years ago, the US Navy launched Vanguard-1 as a response to the Soviet Sputnik. Six decades on, it's still circling our planet. Conceived by the Naval Research Laboratory (NRL) in 1955, Vanguard was to be America's first satellite programme. The Vanguard system consisted of a three-stage rocket designed to launch a civilian scientific spacecraft. The rocket, satellite and an ambitious network of tracking stations would form part of the US contribution to the 1957-58 International Geophysical Year. This global collaboration of scientific research involved 67 nations, including both sides of the Iron Curtain.

Vice President Pence Vows US Astronauts Will Return To the Moon ( 224

Before astronauts go to Mars, they will return to the Moon, Vice President Mike Pence said in a Wall Street Journal op-ed yesterday and in a speech at the National Air and Space Museum today. He touts "humans exploration and discovery" as the new focus of America's space program. This "means establishing a renewed American presence on the moon, a vital strategic goal. And from the foundation of the moon, America will be the first nation to bring mankind to Mars." Engadget reports: There have been two prevailing (and opposing) views when it comes to U.S. endeavors in human spaceflight. One camp maintains that returning to the moon is a mistake. NASA has already been there; it should work hard and set our sights on Mars and beyond. The other feels that Mars is too much of a reach, and that the moon will be easier to achieve in a short time frame. Mars may be a medium-to-long-term goal, but NASA should use the moon as a jumping-off point. It's not surprising that the Trump administration is valuing short-term gains over a longer, more ambitious project. The U.S. will get to Mars eventually, according to Pence, but the moon is where the current focus lies.
