Atlas 5 Rocket Launches $400 Million NASA Satellite Into Space ( 48

A new communications hub has been successfully deployed in space today thanks to the United Launch Alliance Atlas 5 rocket. "TDRS is a critical national asset have because of its importance to the space station and all of our science missions, primarily the Hubble Space Telescope and Earth science missions that use TDRS," said Tim Dunn, NASA's TDRS-M launch director. Spaceflight Now reports: With its main engine running at full throttle, the Atlas 5 booster lifted off at 8:29 a.m. EDT (1229 GMT) from Complex 41 at Cape Canaveral. The 191-foot-tall rocket, generating 860,000 pounds of thrust, aimed eastward and accelerated out of the atmosphere with NASA's TDRS-M spacecraft. Within just five minutes, the rocket had shed 92 percent of its liftoff weight and transitioned to the high-energy Centaur upper stage. An elliptical parking orbit was achieved within 18 minutes of takeoff, beginning a 90-minute quiescent coast higher through space to reach the optimum conditions for the second burn by Centaur. That minute-long boost over the Indian Ocean propelled the 7,610-pound payload into a customized high-perigee geosynchronous transfer orbit. The spacecraft was deployed by the launcher at T+plus 1 hour, 53 minutes to cheers and handshakes all around.

The $408 million TDRS-M was built and launched with the sole purpose to extend the useful life of NASA's constant communications infrastructure, supporting the astronauts around-the-clock aboard the International Space Station, supplying contact with the Hubble Space Telescope and transmitting the data from almost 40 science spacecraft studying Earth's environment and space.


Info on 1.8M Chicago Voters Was Publicly Accessible, But Now Removed From Cloud Service ( 27

A file containing the names, addresses, dates of birth and other information about Chicago's 1.8 million registered voters was published online and publicly accessible for an unknown period of time, the Chicago Board of Election Commissioners said this week. From a report: The acknowledgment came days after a data security researcher alerted officials to the existence of the unsecured files. The researcher found the files while conducting a search of items uploaded to Amazon Web Services, a cloud system that allows users to rent storage space and share files with certain people or the general public. The files had been uploaded by Election Systems & Software, a contractor that helps maintain Chicago's electronic poll books. Election Systems said in a statement that the files "did not include any ballot information or vote totals and were not in any way connected to Chicago's voting or tabulation systems." The company said it had "promptly secured" the files on Saturday evening and had launched "a full investigation, with the assistance of a third-party firm, to perform thorough forensic analyses of the AWS server." State and local officials were notified of the existence of the files Saturday by cybersecurity expert Chris Vickery, who works at the Mountain View, Calif. firm UpGuard.

Bitcoin Is Forking. Again. ( 117

Merely weeks after it was announced that Bitcoin was splitting into two separate entities, the initial version of bitcoin and it's new "bitcoin cash," the network is adding a third version, according to a report. From the article: On Wednesday, a group of bitcoiners scheduled yet another split for the network in November, which would create a third version of bitcoin. So, what makes this version different from the others? Right now, the bitcoin network can sometimes take a long time to process transactions due to so many people using it. This is because the "blocks" of transaction data that get added to bitcoin's public ledger, the blockchain, are getting full. In the weeks preceding the fork, bitcoin coalesced around a solution called "segregated witness," which will change how data is stored in blocks to free up some space when it kicks in later in August. But the size of the blocks themselves will stay at one megabyte on the original bitcoin blockchain. Still, some bitcoiners maintained that the only way to speed bitcoin up for the foreseeable future was to increase the size of blocks themselves. So, a group of bitcoin companies and developers got together and launched a fork called bitcoin cash, which does not include segregated witness. It bumped the size of blocks up to a maximum of eight megabytes. That fork was widely anticipated to be a failure before it happened, but at the time of writing, bitcoin cash is trading above $300 USD per coin, which is comparable to cryptocurrencies like ethereum. Sounds like everyone got what they wanted, right? Oh, no. There's a third group of bitcoin developers, companies, and users who advocate for a "best of both worlds approach." This group includes Bitmain, the largest bitcoin infrastructure company in the world, and legendary bitcoin developer Jeff Garzik. They got together back in May and signed what is known as the "New York Agreement," which bound them to implement a two megabyte block size increase alongside segregated witness via a hard fork within six months of the time of signing. They call the fork Segwit2x. Now, that's exactly what's happening. According to an announcement posted to the Segwit2x GitHub repository, a bitcoin block between one and two megabytes will be created at block 494,784.

Google Lunar X-Prize Extends Deadline Through March 2018 ( 30

schwit1 writes: The Google Lunar X-Prize has announced that it has extended its contest deadline from the end of 2017 to the end of March 2018 for the finalists to complete their lunar rover mission and win the grand prize of $30 million. They also announced several additional consolation prizes that all of the remaining five contestants can win should they achieve lunar orbit ($1.75 million) or successfully achieve a soft landing ($3 million), even if they are not the first to do it. At least one team, Moon Express, will be helped enormously by the extra three months. This gives Rocket Lab just a little extra time to test its rocket before launching Moon Express's rover to the Moon.

NASA is Sending Bacteria Into the Sky on Balloons During the Eclipse ( 54

An anonymous reader shares a report: As the Moon blocks the Sun's light completely next week in a total solar eclipse, more than 50 high-altitude balloons in over 20 locations across the US will soar up to 100,000 feet in the sky. On board will be Raspberry Pi cameras, weather sensors, and modems to stream live eclipse footage. They'll also have metal tags coated with very hardy bacteria, because NASA wants to know whether they will survive on Mars. Every time we send a rover to the Red Planet, our own microorganisms latch on to them and hitch a ride across space. What happens to these bacteria once they're on Mars? Do they mutate? Do they die? Or can they continue living undisturbed, colonizing worlds other than our own? To answer these questions we need to run experiments here on Earth, and the eclipse on August 21st provides the perfect opportunity. The balloons are being sent up by teams of high school and college students from across the US as part of the Eclipse Ballooning Project, led by Angela Des Jardins of Montana State University. When Jim Greene, the director of planetary science at NASA, first heard that over 50 balloons were being flown to the stratosphere to live stream the eclipse, he couldn't believe his ears. "I said, oh my god, that's like being on Mars!" Greene tells The Verge. NASA couldn't pass on the opportunity.

SpaceX Successfully Launches, Recovers Falcon 9 For CRS-12 ( 71

Another SpaceX rocket has been successfully launched from NASA's Kennedy Space Center today, carrying a Dragon capsule loaded with over 6,400 pounds of cargo destined for the International Space Station. This marks an even dozen for ISS resupply missions launched by SpaceX under contract to NASA. TechCrunch reports: The rocket successfully launched from NASA's Kennedy Space Center at 12:31 PM EDT, and Dragon deployed from the second stage as planned. Dragon will rendezvous with the ISS on August 16 for capture by the station's Canadarm 2 robotic appendage, after which it'll be attached to the rocket. After roughly a month, it'll return to Earth after leaving the ISS with around 3,000 pounds of returned cargo on board, and splash down in the Pacific Ocean for recovery. There's another reason this launch was significant, aside from its experimental payload (which included a supercomputer designed to help humans travel to Mars): SpaceX will only use re-used Dragon capsules for all future CRS missions, the company has announced, meaning this is the last time a brand new Dragon will be used to resupply the ISS, if all goes to plan. Today's launch also included an attempt to recover the Falcon 9 first stage for re-use at SpaceX's land-based LZ-1 landing pad. The Falcon 9 first stage returned to Earth as planned, and touched down at Cape Canaveral roughly 9 minutes after launch.

I Bought a Book About the Internet From 1994 and None of the Links Worked ( 180

An anonymous reader shares a report (condensed for space and clarity): For crate-diggers of all stripes, the internet is awesome for one reason: The crate never ends. There's always something new to find online, because people keep creating new things to throw into that crate. But that crate has a hole at the bottom. Stuff is falling out just as quickly, and pieces of history that would stick around in meatspace disappear in an instant online. So as a result, there aren't a lot of websites from 1995 that made it through to the present day. Gopher sites? Odds are low. Text files? Perhaps. The endless pace of linkrot has left books about the internet in a curious limbo -- they're dead trees about the dead-tree killer, after all. [...] Recently, I bought a book -- a reference book, the kind that you can still pick up at Barnes and Noble today. The book, titled Free $tuff From the Internet (Coriolis Group Books, 1994), promises to help you find free content online. And, crucially, it focuses less on the web, which was still quite young, than on many of the alternative protocols of the era. This book links to FTP sites, telnet servers, and Gopher destinations, and I've tried many of them in an effort to figure out whether something, anything in this book works in the present day. These FTP servers were often based at universities which have a vested interest in keeping information online for a long-term period -- think the University of North Carolina, or Kansas State University. But despite this, I could not get most of these servers to load -- they were long ago murdered by the World Wide Web.

SpaceX Will Deliver The First Supercomputer To The ISS ( 98

Slashdot reader #16,185, Esther Schindler writes: "By NASA's rules, not just any computer can go into space. Their components must be radiation hardened, especially the CPUs," reports HPE Insights. "Otherwise, they tend to fail due to the effects of ionizing radiation. The customized processors undergo years of design work and then more years of testing before they are certified for spaceflight." As a result, the ISS runs the station using two sets of three Command and Control Multiplexer DeMultiplexer computers whose processors are 20MHz Intel 80386SX CPUs, right out of 1988. "The traditional way to radiation-harden a spacecraft computer is to add redundancy to its circuits or by using insulating substrates instead of the usual semiconductor wafers on chips. That's expensive and time consuming. HPE scientists believe that simply slowing down a system in adverse conditions can avoid glitches and keep the computer running."

So, assuming the August 15 SpaceX Falcon 9 rocket launch goes well, there will be a supercomputer headed into space -- using off-the-shelf hardware. Let's see if the idea pans out. "We may discover a set of parameters with which a supercomputer can successfully run for at least a year without errors," says Dr. Mark R. Fernandez, the mission's co-principal investigator for software and SGI's HPC technology officer. "Alternately, one or more components of the system will fail, in which case we will then do the typical failure analysis on Earth. That will let us learn what to change to make the systems more reliable in the future."

The article points out that the New Horizons spacecraft that just flew past Pluto has a 12MHz Mongoose-V CPU, based on the MIPS R3000 CPU. "You may remember its much faster ancestor: the chip that took you on adventures in the original Sony PlayStation, circa 1994."

Bitcoin Just Surged Past $4,000. TechCrunch Explains Why ( 154

Saturday night TechCrunch reported the following about Bitcoin: 24 hours ago the cryptocurrency was trading below $3,700. About an hour ago it surged passed $4,000 and has no signs of stopping. It's now trading around $4,135.00. For reference, a week ago Bitcoin hit an all-time high as it passed $3,000 for the first time... So the million-bitcoin question is, why now...?

Two weeks ago Bitcoin went through a hard fork, and came out essentially unscathed... A few days later Bitcoin locked in SegWit, a code modification that fixes malleability issues and frees up space in blocks, allowing for more transactions to be stored in each one. These two code-related developments have helped boost conference in Bitcoin's future. Another reason -- the ICO frenzy. The amount recently raised via initial coin offerings have now (at least temporally) topped amount raised via early stage venture capital. Just last week Filecoin raised $180 million in a few hours. Most investors have to convert fiat currency to bitcoin or other cryptocurrencies to participate in ICOs, which could be driving up the price (and providing some investors with their first taste of bitcoin). Another reason -- Wall Street's new obsession is bitcoin.

Can 'No Man's Sky' Redeem Itself With Its Third Free Update? ( 107

An anonymous reader quotes Engadget's new article on No Man's Sky: Developer Hello Games has gone some way to giving the people what they've wanted Friday with the third major update since the title's launch. "Atlas Rises" (aka update 1.3) adds the beginnings of real-time multiplayer to the space exploration game, though admittedly, "interaction with others is currently very limited." Thanks to the update, up to 16 players can now exist together in the same space. Fellow pilots will appear as floating blue orbs moving about the terrain, and proximity-based voice chat will allow players to plan their next jump together. That's pretty much it, but Hello Games calls it "an important first step into the world of synchronous co-op in No Man's Sky."

Meeting up with other explorers should be a bit easier with the new portal system, which allows players to travel between planets instantly, including to random worlds. Taking a leaf out of Stargate lore, activating a sequence of glyphs on portals can designate specific exit points. Hello Games hopes the community will band together to create something of a database of glyph sequences... There's 30 hours of new storyline gameplay and a new mission system that lets you pick up all kinds of different odd jobs from a forever-updating list. Star systems now are now graded with "wealth, economy and conflict levels," giving you more information on desirable destinations (depending on what you're after). There's a new class of ships, new exotic planet types and a new "interdimensional race" to contend with. Terrain editing is now possible provided you have the appropriate Multi-Tool enhancement, and crashed freighters on the surface of planets serve as new scavenging hotspots... to its credit, Hello Games continues to push massive, free updates for the title, such that the game is now very different to what it was initially.

The game has been heavily discounted to promote the update, and Saturday it became Amazon's #12 best-selling PS4 game -- and one of Steam's top 100 most-played games.

28 Years Later, Pioneering Tech Magazine 'Mondo 2000' Relaunches Online ( 35

In 1989 Mondo 2000 magazine ran an editorial promising they'd cover "the leading edge in hyperculture...the latest in human/technological interactive mutational forms as they happen." 28 years later, they're now heckling that editorial as they relaunch into a web site. Slashdot reader DevNull127 quotes Motherboard's interview with R.U. Sirius, the founder of Mondo 2000 (as well as its predecessors High Frontiers and Reality Hackers): "It was my idea to merge psychedelics and emerging technologies, and the culture around technology," Sirius said, citing Timothy Leary, writer Robert Anton Wilson and counterculture magazine The Whole Earth Catalog among his inspirations... "I kind of found my way into that particular stream of bohemian culture. It was probably a minority, but there had always been that idea of letting robots replace human work." Soon High Frontiers evolved into a glossy magazine, Reality Hackers ("Some distributors at the time thought it was about hacking people up, and put it on the shelf next to murder mystery magazines"), and later Mondo 2000, which ran from 1989 till 1998...

"We really had to work to convince people that technology was defining the future. Nobody really got it. Doug Rushkoff wrote his book Cyberia, and his first book company cancelled its publication because they said the internet was a fad and that it would be over by the time the book came out"... While he uses Facebook and Twitter, Sirius is critical of their role in colonising what was once a more democratic and open space. "People are being herded into little buildings -- or huge ones -- in what was supposed to be a wide open space in which everybody created their own sites. It's a complete corporate takeover of the net, Facebook in particular... It's definitely not what we were expecting."

Mondo 2000's new online relaunch includes audio of a conversation between William Gibson and Timothy Leary about a Neuromancer game to accompany a proposed film back in 1989. (Gibson complained "That was no interview! That was a drunken business meeting!" when first informed of the magazine's plans to publish it, though he eventually "became friendly.") There's also a 1987 discussion about mind technologies with 73-year-old William S. Burroughs (who was also "an advocate of high technology, and the 'brain machine'"), plus an unpublished John Shirley essay titled "The Next Fifty Years: Why I'm Optimistic Because Everything Will Be Terrible" and new pieces by Paul Krassner ("Alternative Facts") and M.Christian ("La Petite Mort: The Death Of Sex").

NASA Looks At Reviving Atomic Rocket Program ( 122

Big Hairy Ian shares a report from New Atlas: When the first manned mission to Mars sets out, it may be on the tail of an atomic rocket engine. The Space Race vintage technology could have a renaissance at NASA after the space agency's Marshall Space Flight Center in Huntsville, Alabama signed a contract with BWXT Nuclear Energy to develop updated Nuclear Thermal Propulsion (NTP) concepts and new fuel elements to power them.

Today, with NASA once again considering the challenges of sending astronauts to Mars, the nuclear option is back on the table as part of the agency's Game Changing Development program. Under this, NASA has awarded BMXT, which supplies nuclear fuel to the U.S. Navy, a $18.8-million contract running through September 30, 2019 to look into the possibility of developing a new engine using a new type of fuel. Unlike previous designs using highly enriched uranium, BMXT will study the use of Low-Enriched Uranium (LEU), which has less than 20 percent of fissile uranium 235. This will provide a number of advantages. Not only is it safer than the highly enriched fuel, but the security arrangements are less burdensome, and the handling regulations are the same as those of a university research reactor. If NASA determines next month that the LEU engine is feasible, the project will conduct testing and refine the manufacturing process of the Cermet fuel elements over the course of a year, with testing of the full-length Cermet fuel rods to be conducted at Marshall.

Slashdot reader Big Hairy Ian adds: "At the very least it looks much more feasible than Project Orion."


Startup To Put Cellphone Tower on the Moon ( 76

An astronaut wandering the moon next year could use a smartphone to call home. If everything goes according to a plan, that is. A German startup is preparing to set up the first telecommunication infrastructure on the lunar surface. From a report: The German company Part Time Scientists, which originally competed for the Google Lunar X Prize race to the moon, plans to send a lander with a rover in late 2018 to visit the landing site of Apollo 17. (Launched in 1972, this was NASA's final Apollo mission to the moon.) Instead of using a complex dedicated telecommunication system to relay data from the rover to the Earth, the company will rely on LTE technology -- the same system used on Earth for mobile phone communications. "We are cooperating with Vodafone in order to provide LTE base stations on the moon," Karsten Becker, who heads embedded electronics development and integration for the startup, told "What we are aiming to do is to provide commercial service to bring goods to the moon and also to provide services on the surface of the moon," Becker added.

Astronomers Detect Four Earth-Sized Planets Orbiting The Nearest Sun-Like Star ( 100

Tim Stephens reports via The University of California in Santa Cruz: A new study by an international team of astronomers reveals that four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye. These planets have masses as low as 1.7 Earth mass, making them among the smallest planets ever detected around nearby sun-like stars. Two of them are super-Earths located in the habitable zone of the star, meaning they could support liquid surface water. The planets were detected by observing the wobbles in the movement of tau Ceti. This required techniques sensitive enough to detect variations in the movement of the star as small as 30 centimeters per second. The outer two planets around tau Ceti are likely to be candidate habitable worlds, although a massive debris disc around the star probably reduces their habitability due to intensive bombardment by asteroids and comets.

Developers Explain Why iOS Apps Are Getting Bulkier ( 140

Reader joshtops shares a report: Apps are getting bigger in size, in part because developers add new features, something many users obviously appreciate, developers say. "Apps are getting bigger because iOS devices are more powerful, and developers are building more and more complex things for them without considering the impact the size will have around the world," developer Stephen Troughton-Smith tells Gadgets 360. But in part, it is also happening because developers are being careless, and adding more than one instance of files, Troughton-Smith added. "So Facebook, Twitter, and other large companies have perhaps tens or hundreds of people building their iOS apps. A lot of the components for these apps are developed independently as components, or frameworks. For each additional component you glue together into an app, there is some overhead," he explained. "Some of the teams will duplicate functionality some other team wrote. Images and other resources end up being duplicated." The high-resolution image assets that developers are required to add also contributes to the size of an app, two India-based developers, and Peter Steinberger, founder and CEO of PSPDFKit, a dev kit that is used by several popular PDF apps, told Gadgets 360. Apple can itself take some blame, too. Developers using Apple's Swift language, which the company introduced in 2014, are required to add several components to their apps that make them heavier. "Apple's new Swift language, for example, requires a bunch of components to be embedded each time it's used, because it's not yet 'ABI stable,'" Troughton-Smith explained. This means developers need to embed the versions of libraries they've developed against, and not count on the one available on the system. Another developer who didn't want to be identified said a typical app built with Swift language requires as many as 30 Swift runtime libraries to be stuffed within the app. On top of this, he added, "you will be surprised at just how many apps use common code found at places like GitHub. Developers often don't care about removing the bits that wasn't relevant to their app," he added.
