Amazon, NVIDIA and The CIA Want To Teach AI To Watch Us From Space ( 58

An anonymous reader quotes a report from MIT Technology Review: Satellite operator DigitalGlobe is teaming up with Amazon, the venture arm of the CIA, and NVIDIA to make computers watch the Earth from above and automatically map our roads, buildings, and piles of trash. MIT Technology Review reports: "In a joint project, DigitalGlobe today released satellite imagery depicting the whole of Rio de Janeiro to a resolution of 50 centimeters. The outlines of 200,000 buildings inside the city's roughly 1,900 square kilometers have been manually marked on the photos. The SpaceNet data set, as it is called, is intended to spark efforts to train machine-learning algorithms to interpret high-resolution satellite photos by themselves. DigitalGlobe says the SpaceNet data set should eventually include high-resolution images of half a million square kilometers of Earth, and that it will add annotations beyond just buildings. DigitalGlobe's data is much more detailed than publicly available satellite data such as NASA's, which typically has a resolution of tens of meters. Amazon will make the SpaceNet data available via its cloud computing service. Nvidia will provide tools to help machine-learning researchers train and test algorithms on the data, and CosmiQ Works, a division of the CIA's venture arm In-Q-Tel focused on space, is also supporting the project." "We need to develop new algorithms for this data," says senior vice president at DigitalGlobe, Tony Frazier. He goes on to say that health and aid programs are to benefit from software that is able to map roads, bridges and various other infrastructure. The CEO of Descartes Labs, Mark Johnson, a "startup that predicts crop yields from public satellite images," says the data that is collected "should be welcome to startups and researchers," according to MIT Technology Review. "Potential applications could include estimated economic output from activity in urban areas, or guiding city governments on how to improve services such as trash collections, he says."

NASA's Voyager 2 Flew By Saturn 35 Years Ago Today ( 58

An anonymous reader quotes a report from Thirty-five years ago today, a NASA spacecraft got an up-close look at beautiful, enigmatic Saturn. On Aug. 25, 1981, the Voyager 2 probe zoomed within 26,000 miles (41,000 kilometers) of the ringed planet's cloud tops. The discoveries made by Voyager 2 -- and by its twin, Voyager 1, which had flown past Saturn nine months earlier -- reshaped scientists' understanding of the Saturn system and planted the seed for NASA's Cassini mission, which began orbiting the ringed planet in 2004, NASA officials said. Voyager 1 and Voyager 2 launched a few weeks apart in 1977, tasked with performing a "grand tour" of the solar system's big planets -- Jupiter, Saturn, Uranus and Neptune. The two spacecraft accomplished that goal, eyeing all four gaseous worlds up close, and also studying 48 of their moons. (Voyager 1 flew past Jupiter and Saturn, while Voyager 2 had close encounters with all four planets.) The Voyagers weren't the first spacecraft to fly by Saturn; that distinction belongs to NASA's Pioneer 11 probe, which did so in 1979. But the Voyagers broke a lot of new ground; they discovered four new Saturn moons, for example, and revealed an incredible diversity of landscapes on satellites such as Dione, Tethys and Iapetus, NASA officials said. August 25th appears to be a good day for nerds. You can view some out-of-this-world photos from NASA's Voyager 1 and 2 probes here.



Earth-Like Planet, With Ambitious Life Possibility, Found Orbiting the Star Next Door ( 218

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 Military

The US Army Has Too Many Video Games ( 82

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 ( 250

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 ( 107

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."

Eleven Reasons To Be Excited About The Future of Technology ( 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.
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.
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 ( 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 ( 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.



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