NASA Astronaut Jeff Williams Sets New US Space Endurance Record With 521 Days (cbsnews.com) 34

An anonymous reader quotes a report from CBS News: Space station commander Jeff Williams set a new U.S. space endurance record Wednesday, his 521st day in orbit over four missions, eclipsing the 520-day record set earlier this year by astronaut Scott Kelly at the end of his nearly one-year stay aboard the lab complex. Williams now moves up to 17th on the list of the world's most experienced astronauts and cosmonauts. The overall record is held by cosmonaut Gennady Padalka, who logged 878 days in orbit over five missions. Williams, Soyuz TMA-20M commander Alexey Ovchinin and flight engineer Oleg Skripochka were launched to the space station March 18. They plan to return to Earth Sept. 6 (U.S. time), landing in Kazakhstan to close out a 172-day mission. At landing, Williams will have logged 534 days aloft, moving him up to 14th on the space endurance list. Williams first flew in space in 2000 aboard the shuttle Atlantis, the third shuttle flight devoted to station assembly. He served as a flight engineer aboard the station in 2006 and completed a second long-duration stay in 2010, serving as a flight engineer and then commander of Expedition 22. "I wanted to congratulate you on passing me up here in total number of days in space," Kelly radioed Williams Wednesday. "It's great to see another record broken. [...] But I do have one question for you. And my question is, do you have another 190 days in you?" Kelly was referring to the time Williams' current mission would have to be extended to equal Kelly's U.S. single-flight record. Williams laughed, saying "190 days. That question's not for me, that's for my wife!"

Earth-Like Planet, With Ambitious Life Possibility, Found Orbiting the Star Next Door (nature.com) 189

There's another Earth out there. For real, this time. Astronomers announced on Wednesday that they had detected a planet orbiting Proxima Centauri, the closest neighbor to our solar system. Intriguingly, the planet is in the star's "Goldilocks zone," they said, a place that hints that it may not be too hot nor too cold. Which in turn means that liquid water could exist at the surface, and by extension, it raises the possibility of life. Nature reports:"The search for life starts now," says Guillem Anglada-Escude, an astronomer at Queen Mary University of London and leader of the team that made the discovery. Humanity's first chance to explore this nearby world may come from the recently announced Breakthrough Starshot initiative, which plans to build fleets of tiny laser-propelled interstellar probes in the coming decades. Travelling at 20% of the speed of light, they would take about 20 years to cover the 1.3 parsecs from Earth to Proxima Centauri. Proxima's planet is at least 1.3 times the mass of Earth. The planet orbits its red-dwarf star -- much smaller and dimmer than the Sun -- every 11.2 days. "If you tried to pick the type of planet you'd most want around the type of star you'd most want, it would be this," says David Kipping, an astronomer at Columbia University in New York City. "It's thrilling."Much about the planet is still unknown. Astronomers have some ideas about its size and distance from its parent star. Scientists say they are working off computer models that offer mere hints of what's possible. Also, there's no picture available for this planet as of yet.

The US Army Has Too Many Video Games (vice.com) 80

An anonymous reader shares a Motherboard report:The US Army sees itself in a transitional period. Unlike a decade ago, soldiers are training less today on how to conduct "stability" operations for a counter-insurgency campaign, and more on what the Army does best: fighting other armies. But training is expensive and requires time and a lot of space. Training a gunner for an M-1 Abrams tank means reserving time on a limited number of ranges and expending real ammunition. So to lower costs and make training more efficient -- in theory -- the Army has adopted a variety of games to simulate war. There's just a few problems. Some of the Army's virtual simulators sit collecting dust, and one of them is more expensive and less effective than live training. At one base, soldiers preferred to play mouse-and-keyboard games over a more "realistic" virtual room. Then again, the Army has cooler games than you do. M-1 tank gunners, for example, can train inside a full-scale, computerized mock-up of their station called the Advanced Gunnery Training System, which comes inside a large transportable container. Instead of looking through real sights down a range, the soldier squints through a replica and sees a virtual simulacrum of, say, an enemy tank. Push a button and the "cannon" fires. The Army fields similar systems for the Stryker, a wheeled armored troop transport that fits an optional 105-millimeter gun. Soldiers train inside another simulated gunnery station for the M-2 Bradley fighting vehicle. Another system, Common Driver, simulates a variety of military vehicles.

NASA's Outsourced Computer People Are Even Worse Than You Might Expect (arstechnica.com) 229

Eric berger, writing for ArsTechnica: As part of a plan to help NASA "modernize" its desktop and laptop computers, the space agency signed a $2.5 billion services contract with HP Enterprise Services in 2011. According to HP (now HPE), part of the Agency Consolidated End-User Service (ACES) program the computing company would "modernize NASA's entire end-user infrastructure by delivering a full range of personal computing services and devices to more than 60,000 users." HPE also said the program would "allow (NASA) employees to more easily collaborate in a secure computing environment." The services contract, alas, hasn't gone quite as well as one might have hoped. This week Federal News Radio reported that HPE is doing such a poor job that NASA's chief information officer, Renee Wynn, could no longer accept the security risks associated with the contract. Wynn, therefore, did not sign off on the authority to operate (ATO) for systems and tools.A spokesperson for NASA said: "NASA continues to work with HPE to remediate vulnerabilities. As required by NASA policy, system owners must accomplish this remediation within a specified period of time. For those vulnerabilities that cannot be fully remediated within the established time frame, a Plan of Actions and Milestones (POAM) must be developed, approved, and tracked to closure."

NASA Reconnects With 'Lost' STEREO-B Satellite (businessinsider.com) 94

NASA lost contact with its STEREO-B spacecraft twenty-two months ago during a routine 72-hour test. On Sunday, the spacecraft reconnected with NASA roughly 189 million miles away from Earth. While that would seem like a cause for celebration, "the very hard and scary work is just the beginning, says Stereo project scientist Joe Gurman, as the agency has to turn on the computer to learn more about the current state of the spacecraft -- a process that may make the craft lose contact with them again. Slashdot user bongey writes: NASA may have only two minutes or less to fix a STEREO-B satellite before the computer causes it to lose contact again. NASA lost contact with their STEREO-B satellite nearly twenty-two months ago when performing a routine test. NASA scientists are afraid to turn on the computer at this point because it may cause them to lose contact again. A more detailed technical summary can be found here. "We have something like two minutes between when STEREO-B receives the command to boot up one of its computers and when it starts doing what we don't want it to do," Gurman said. Business Insider writes, "Making matters worse, it takes about 20 seconds to send commands to the spacecraft -- a data rate that makes a dial-up modem seem lightning fast."

Google Search Removes 'Mobile-Friendly' Label, Will Tackle Interstitials Next (venturebeat.com) 79

An anonymous reader quotes a report from VentureBeat: Google today announced two updates to mobile search results: an aesthetic one rolling out now and an algorithmic one coming next year. The former consists of removing the "mobile-friendly" label in search results and the latter will punish mobile sites that use interstitials. The goal is to "make finding content easier for users," though as always, the company didn't share exactly how much of an impact users and webmasters can expect. The report adds: "If your site is in the 15 percent group, here's a quick recap. A webpage is considered 'mobile friendly' if it meets the following criteria, as detected in real time by Googlebot: Avoids software that is not common on mobile devices, like Flash; Uses text that is readable without zooming; Sizes content to the screen so users don't have to scroll horizontally or zoom; Places links far enough apart so that the correct one can be easily tapped. The company now wants to tackle 'intrusive interstitials' as they 'provide a poorer experience to users than other pages where content is immediately accessible.' After January 10, 2017, pages where content is not easily accessible when coming from mobile search results 'may not rank as highly.' Interstitials that Google doesn't like include showing a popup that covers the main content (immediately or delayed), displaying a standalone interstitial that the user has to dismiss before accessing the main content, and using a layout where the above-the-fold portion is similar to a standalone interstitial but the original content is inlined underneath. Interstitials that Google deems OK include legal obligations (cookie usage or for age verification), login dialogs on sites where content is not publicly indexable, and banners that use a reasonable amount of screen space and are easily dismissible."

NanoRacks Plans To Turn Used Rocket Fuel Tanks Into Space Habitats (ieee.org) 124

An anonymous reader writes from a report via IEEE Spectrum: A couple of weeks ago NASA announced it has committed $65 million to six companies over the course of two years for the purpose of developing and testing deep-space habitats that could be used for future missions to Mars. One of the six companies, called NanoRacks, is attempting to take empty fuel tanks from the upper stages of rockets and turn them into space habitats on-orbit. IEEE Spectrum reports: "A rocket like the the Atlas V, which can deliver payloads of nearly 19,000 kg to low Earth orbit, consists of three primary pieces: on the bottom, you've got the first stage booster, which consists of a huge engine and some big tanks holding kerosene fuel and oxidizer. Above that, there's the second stage, which consists of one or two smaller engines, a big tank for storing liquid hydrogen fuel, and a smaller tank for oxidizer. The payload, which is what all of the fuss is about, sits on top. The first stage launches the rocket off of the pad and continues firing for about four minutes. Meanwhile, the second stage fires up its own engine (or engines) to boost the payload the rest of the way into orbit. On the Atlas V, the second stage is called Centaur. Once Centaur gets its payload where it needs to go, it separates, and then suicides down into Earth's atmosphere. Getting a payload into space is so expensive because you have to build up this huge and complicated rocket, with engines and guidance systems and fuel tanks and stuff, and then you basically use it for like 15 minutes and throw it all away. But what about the second stage? You've got a whole bunch of hardware that made it to orbit, and when getting stuff to orbit costs something like $2,500 per kilogram, you then tell it to go it burn itself up in the atmosphere, because otherwise it's just useless space junk." NanoRacks thinks this is wasteful, so they want to turn these tanks into deep space habitats. IEEE notes that the hydrogen fuel tank on a Centaur upper stage has a diameter of over 4 meters, and an interior volume of 54 cubic meters, while the inflatable BEAM module that arrived at the ISS earlier this year has an interior volume of 16 cubic meters. For more details, IEEE Spectrum spoke with Jeff Manber, CEO of NanoRacks, and Mike Johnson, NanoRacks' Chief Designer. You can read their responses here.

Astronauts Successfully Install Parking Spot At ISS (phys.org) 45

An anonymous reader quotes a report from Phys.Org: With more private spaceship traffic expected at the International Space Station in the coming years, two U.S. astronauts embarked on a spacewalk Friday to install a special parking spot for them. Americans Jeff Williams and Kate Rubins switched their spacesuits to internal battery power at 8:04 (1204 GMT) and floated outside the orbiting laboratory to begin the work of attaching the first of two international docking adaptors. The spacewalkers finished the task in just over two hours. "With that, we have a new port of call," said NASA commentator Rob Navias, as the space station flew over Singapore at 10:40 am (1440 GMT). NASA describes the docking adaptor as a "metaphorical gateway to a future" that will allow a new generation of U.S. spacecraft -- the first since the space shuttle program ended in 2011 -- to carry astronauts to the space station. The second docking adaptor is expected to be installed in 2018. Built by Boeing, the circular adaptor measures around 42 inches (one meter) tall and about 63 inches wide. The adaptors will work with Boeing's CST-100 Starliner and SpaceX's Crew Dragon, two spaceships under construction that are planned to ferry astronauts to the space station. The docking adaptor is more sophisticated than past equipment because it will allow automatic parking instead of the current grapple and berthing process, which is managed by astronauts.

Eleven Reasons To Be Excited About The Future of Technology (medium.com) 282

Chris Dixon, an American internet entrepreneur and investor in a range of tech and media companies including Kickstarter and Foursquare has written an essay on Medium highlighting some of the reasons why we should be excited about the future of technology. The reasons he has listed are as follows: 1. Self-Driving Cars: Self-driving cars exist today that are safer than human-driven cars in most driving conditions. Over the next 3-5 years they'll get even safer, and will begin to go mainstream.
2. Clean Energy: Attempts to fight climate change by reducing the demand for energy haven't worked. Fortunately, scientists, engineers, and entrepreneurs have been working hard on the supply side to make clean energy convenient and cost-effective.
3. Virtual and Augmented Reality: Computer processors only recently became fast enough to power comfortable and convincing virtual and augmented reality experiences. Companies like Facebook, Google, Apple, and Microsoft are investing billions of dollars to make VR and AR more immersive, comfortable, and affordable.
4. Drones and Flying Cars: GPS started out as a military technology but is now used to hail taxis, get mapping directions, and hunt Pokemon. Likewise, drones started out as a military technology, but are increasingly being used for a wide range of consumer and commercial applications.
5. Artificial Intelligence: Artificial intelligence has made rapid advances in the last decade, due to new algorithms and massive increases in data collection and computing power.
6. Pocket Supercomputers for Everyone: By 2020, 80% of adults on earth will have an internet-connected smartphone. An iPhone 6 has about 2 billion transistors, roughly 625 times more transistors than a 1995 Intel Pentium computer. Today's smartphones are what used to be considered supercomputers.
7. Cryptocurrencies and Blockchains: Protocols are the plumbing of the internet. Most of the protocols we use today were developed decades ago by academia and government. Since then, protocol development mostly stopped as energy shifted to developing proprietary systems like social networks and messaging apps. Cryptocurrency and blockchain technologies are changing this by providing a new business model for internet protocols. This year alone, hundreds of millions of dollars were raised for a broad range of innovative blockchain-based protocols.
8. High-Quality Online Education: While college tuition skyrockets, anyone with a smartphone can study almost any topic online, accessing educational content that is mostly free and increasingly high-quality.
9. Better Food through Science: Earth is running out of farmable land and fresh water. This is partly because our food production systems are incredibly inefficient. It takes an astounding 1799 gallons of water to produce 1 pound of beef. Fortunately, a variety of new technologies are being developed to improve our food system.
10. Computerized Medicine: Until recently, computers have only been at the periphery of medicine, used primarily for research and record keeping. Today, the combination of computer science and medicine is leading to a variety of breakthroughs.
11. A New Space Age: Since the beginning of the space age in the 1950s, the vast majority of space funding has come from governments. But that funding has been in decline: for example, NASA's budget dropped from about 4.5% of the federal budget in the 1960s to about 0.5% of the federal budget today.

US Air Force Wants To Plasma Bomb The Sky To Improve Radio Communication (newscientist.com) 159

An anonymous reader quotes a report from New Scientist: [The U.S. Air Force has plans to improve radio communication over long distances by detonating plasma bombs in the upper atmosphere using a fleet of micro satellites. It's not the first time we've tried to improve radio communication by tinkering with the ionosphere. HAARP, the High Frequency Active Auroral Research Program in Alaska, stimulates the ionosphere with radiation from ground-based antennas to produce radio-reflecting plasma.] Now the USAF wants to do this more efficiently, with tiny satellites -- such as CubeSats -- carrying large volumes of ionized gas directly into the ionosphere. As well as increasing the range of radio signals, the USAF says it wants to smooth out the effects of solar winds, which can knock out GPS, and also investigate the possibility of blocking communication from enemy satellites. [There are at least two major challenges. One is building a plasma generator small enough to fit on a CubeSat -- roughly 10 centimeters cubed. Then there's the problem of controlling exactly how the plasma will disperse once it is released. The USAF has awarded three contracts to teams who are sketching out ways to tackle the approach. The best proposal will be selected for a second phase in which plasma generators will be tested in vacuum chambers and exploratory space flights.]

Satellite Images Can Map Poverty (bbc.com) 120

A new study using satellite images and machine learning plans to map poverty from space in an effort to "fix the world's problems." Satellite imagery can be less dangerous, slow and expensive than gathering the data on the ground. BBC reports: "A team from Stanford University were able to train a computer system to identify impoverished areas from satellite and survey data in five African countries. The latest study looked at daylight images that capture features such as paved roads and metal roofs -- markers that can help distinguish different levels of economic wellbeing in developing countries. They then used a sophisticated computer model to categorize the various indicators in daytime satellite images of Nigeria, Tanzania, Uganda, Rwanda and Malawi. 'If you give a computer enough data it can figure out what to look for. We trained a computer model to find things in imagery that are predictive of poverty,' said Dr Burke. 'It finds things like roads, like urban areas, like farmland, it finds waterways -- those are things we recognize. It also finds things we don't recognize. It finds patterns in imagery that to you or I don't really look like anything... but it's something the computer has figured out is predictive of where poor people are.' The researchers used imagery from countries for which survey data were available to validate the computer model's findings." The results of the study are published in the journal Science.

Astronauts To Install A Parking Space For SpaceX and Boeing At The ISS (popularmechanics.com) 77

Since Boeing and SpaceX will begin sending NASA astronauts into orbit next year, the International Space Station is going to need a place for them to park. Astronauts Jeff Williams and Kate Rubins will journey outside the ISS on Friday to install a new docking adapter for these two private companies. Popular Mechanics reports: "Installing these adapters is a necessary step in NASA's Commercial Crew Program, which seeks to spur development of commercial crew spacecraft. The spacewalk is scheduled to begin at 8:05 a.m. on Friday, and live coverage will start at 6:30. This will be Williams' fourth spacewalk, and Rubins' first." In the meantime, you can watch this video describing exactly what the spacewalk will entail.

From Now On You'll Be Able To Access NASA Research For Free (vice.com) 64

An anonymous reader writes:Fancy some super nerdy bedtime reading? NASA has announced that it will now provide public access to all journal articles on research funded by the agency. Any scientists publishing NASA-funded work will be required to upload their papers to a free, online database called PubSpace within a year of publication. PubSpace is managed by the National Institutes of Health (NIH) PubMed Central, which archives biomedical research. You can see NASA-funded studies here, with recent examples including a paper on cardiovascular disease in Apollo astronauts and one on Martian tsunamis caused by meteor impacts. NASA explains that the new web portal is a response to a 2013 government request for federally-funded research to be more accessible. There are a few obvious exceptions to what's included, such as and material that's related to national security or affected by export controls. NASA's openness follows a trend to make science results more accessible outside of published, often paywalled journals.

Intel Unveils Project Alloy 'Merged Reality' Wireless Headset (hothardware.com) 43

MojoKid writes: Intel CEO Bryan Krzanich took to the stage at the Moscone Center in San Francisco today to kick off this year's Intel Developers Forum. Kyrzanich unveiled a number of new projects and products including a product code-named "Project Alloy." The device is an un-tethered, merged reality Head Mounted Device (HMD) that combines compute, graphics, multiple RealSense modules, various sensors, and batteries into a self-contained headset that offers a full six degrees of freedom. Unlike the Oculus Rift and HTC Vive, Project Alloy does not need to be wired to a PC or other device and it does not require externally mounted sensors to define a virtual space. Instead, it uses RealSense cameras to map the actual physical world you're in while wearing the HMD. The RealSense cameras also allow the device to bring real-world objects into the virtual world, or vice versa. The cameras and sensors used in Project Alloy offer full depth sensing, so obstacles can be mapped, and people and objects within camera range -- like your hand, for example -- can be brought into the virtual world and accurately tracked. During a live, on-stage demo performed by Intel's Craig Raymond, Craig's hand was tracked and all five digits, complete with accurate bones and joint locations, were brought into the the VR/AR experience. Project Alloy will be supported by Microsoft's Windows Holographics Shell framework.

Cable Expands Broadband Domination as AT&T and Verizon Lose Customers (arstechnica.com) 104

The cable industry's grip on the U.S. broadband space increased last quarter, with Comcast and Charter gaining nearly 500,000 subscribers, combined. Phone companies AT&T, Verizon, CenturyLink, and Frontier, however, all lost Internet customers. ArsTechnica reports:The 14 largest ISPs, accounting for 95 percent of the US market, gained 192,510 Internet customers in Q2 2016, bringing the total to 91.9 million, Leichtman Research Group reported today. Cable companies accounted for all of the gains, adding 553,293 subscribers for a new total of 57 million. The phone companies lost 360,783 subscribers, bringing them down to 34.9 million. Phone companies' losses more than doubled since Q2 2015, when they lost about 150,000 subscribers. [...] Comcast and Charter, the two biggest ISPs, led the way in subscriber gains. Comcast added 220,000 broadband subscribers to boost its total to 24 million, while Charter (the new owner of Time Warner Cable) added 277,000 subscribers for a new total of 21.8 million. AT&T lost 123,000 subscribers, lowering its total to 15.6 million. Verizon lost 83,000, leaving it with 7 million Internet customers. CenturyLink and Frontier lost 66,000 and 77,000, respectively.

China Launches World's First Quantum Communications Satellite (theverge.com) 102

hackingbear quotes a report from The Verge: China's quantum network could soon span two continents, thanks to a satellite launched earlier today. Launched at 1:40pm ET, the Quantum Science Satellite is designed to distribute quantum-encrypted keys between relay stations in China and Europe. When working as planned, the result could enable unprecedented levels of security between parties on different continents. China's new satellite would put that same fiber-based quantum communication system to work over the air, utilizing high-speed coherent lasers to connect with base stations on two different continents. The experimental satellite's payload also includes controllers and emitters related to quantum entanglement. The satellite will be the first device of its kind if the quantum equipment works as planned. According to the Wall Street Journal, the project was first proposed to the European Space Agency in 2001 but was unable to gain funding.

There May Be A Fifth Force of Nature, Study Suggests (space.com) 240

According to a paper published in the journal Physical Review Letters, physicists at the University of California, Irvine, may have discovered a previously unknown subatomic particle that's evidence of a fifth fundamental force of nature. Space.com reports: "[Professor of physics and astronomy Jonathan Feng] and his colleagues analyzed data gathered recently by experimental nuclear physicists at the Hungarian Academy of Sciences, who were trying to find 'dark photons' -- hypothetical indicators of mysterious dark matter. Dark matter is thought to make up about 85 percent of all matter in the universe, but it neither absorbs nor emits light, so it's impossible to detect directly. 'The experimentalists weren't able to claim that it was a new force,' Feng said. 'They simply saw an excess of events that indicated a new particle, but it was not clear to them whether it was a matter particle or a force-carrying particle.' The new work by Feng and his team suggests that the Hungarians found not a 'dark photon' but rather a 'protophobic X boson' -- a strange particle whose existence could indicate a fifth force of nature. The known electromagnetic force acts on protons and electrons, but this newfound particle apparently interacts only with protons and neutrons, and then only at very short distances, researchers said. The potential fifth force may be linked to the electromagnetic and strong and weak nuclear forces, as 'manifestations of one grander, more fundamental force,' Feng said. It's also possible that the universe of 'normal' matter and forces has a parallel 'dark' sector, with its own matter and forces, Feng added. 'It's possible that these two sectors talk to each other and interact with one another through somewhat veiled but fundamental interactions,' Feng said. 'This dark-sector force may manifest itself as this protophobic force we're seeing as a result of the Hungarian experiment. In a broader sense, it fits in with our original research to understand the nature of dark matter.'"

Locke2005 writes: I've always speculated that there might be forces of nature that we never observed because they were on a much larger or smaller scale than we could detect easily. But now Jonathan Feng, a professor of physics and astronomy at the University of California, Irvine, is suggesting there may actually be a fifth force. Of course, this might vanish just like the Higgs Boson evidence did. Can anybody explain better what it was they detected, and why it is being interpreted as evidence of a previously unknown force?

Astronomers To Announce Discovery of a Nearby 'Earth-Like' Planet (seeker.com) 344

astroengine quotes a report from Seeker: Scientists are preparing to unveil a new planet in our galactic neighborhood which is "believed to be Earth-like" and orbits its star at a distance that could favor life, German weekly Der Spiegel reported Friday. The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system, the magazine said, quoting anonymous sources.

"The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface -- an important requirement for the emergence of life," said the magazine.

It's orbiting our sun's nearest neighboring star -- just 4.25 light years away -- meaning it could someday be considered for the world's first interstellar mission.

Fourth SpaceX Rocket Successfully Landed on A Drone Ship (theverge.com) 71

Saturday a SpaceX rocket completed the company's fourth successful landing at sea (watched by over 100,000 viewers on YouTube and Flickr). Saturday's landing means Elon Musk's company has now recovered more than half the rockets they've launched. An anonymous Slashdot reader quotes Saturday's report from The Verge: Tonight's landing was particularly challenging for SpaceX... The Falcon 9 had to carry its onboard satellite -- called JCSAT-16 -- into...a highly elliptical orbit that takes the satellite 20,000 miles out beyond Earth's surface. Getting to GTO requires a lot of speed and uses up a lot of fuel during take off, more so than getting to lower Earth orbit. That makes things difficult for the rocket landing afterward...there's less fuel leftover for the vehicle to reignite its engines and perform the necessary landing maneuvers.

CEO Elon Musk said the company is aiming to launch its first landed rocket sometime this fall...SpaceX's president, Gwynne Shotwell, estimates that reusing these landed Falcon 9 vehicles will lead to a 30 percent reduction in launch costs.

SpaceX named their drone ship "Of Course I Still Love You."

Maybe There's No Life in Space Because We're Too Early 250

Long-time Slashdot reader sehlat shares "a highly accessible summary" of a new theory about why we haven't yet find life on other planets -- that "we're not latecomers, but very, very early." From Lab News: The universe is 13.8 billion years old, with Earth forming less than five billion years ago. One school of thought among scientists is that there is life billions of years older than us in space. But this recent study in the Journal of Cosmology and Astroparticle Physics argues otherwise... "We find that the chance of life grows much higher in the distant future..."

Stars larger than approximately three times the Sun's mass will perish before life has a chance to evolve... The smallest stars weigh less than a tenth as much as the sun and will glow for 10 trillion years, meaning life has lot of time to begin on those planets orbiting them in the 'habitable zone'. The probability of life increases over time so the chance of life is many times higher in the distant future than now.

The paper ultimately concludes that life "is most likely to exist near 0.1 solar-mass stars ten trillion years from now."
