Google Lunar X-Prize Extends Deadline Through March 2018 (space.com) 27

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 (cnbc.com) 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 (techcrunch.com) 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 (vice.com) 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 (hpe.com) 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 (techcrunch.com) 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? (engadget.com) 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 (mondo2000.com) 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 (newatlas.com) 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 (space.com) 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 Space.com. "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 (ucsc.edu) 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 (ndtv.com) 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.

Can Primordial Black Holes Alone Account For Dark Matter? 135

thomst writes: Slashdot stories have reported extensively on the LIGO experiments' initial detection of gravity waves emanating from collisions of primordial black holes, beginning, on February 11, 2016, with the first (and most widely-reported) such detection. Other Slashdot articles have chronicled the second LIGO detection event and the third one. There's even been a Slashdot report on the Synthetic Universe supercomputer model that provided support for the conclusion that the first detection event was, indeed, of a collision between two primordial black holes, rather than the more familiar stellar remnant kind that result from more recent supernovae of large-mass stars.

What interests me is the possibility that black holes of all kinds -- and particularly primordial black holes -- are so commonplace that they may be all that's required to explain the effects of "dark matter." Dark matter, which, according to current models, makes up some 26% of the mass of our Universe, has been firmly established as real, both by calculation of the gravity necessary to hold spiral galaxies like our own together, and by direct observation of gravitational lensing effects produced by the "empty" space between recently-collided galaxies. There's no question that it exists. What is unknown, at this point, is what exactly it consists of.

The leading candidate has, for decades, been something called WIMPs (Weakly-Interacting Massive Particles), a theoretical notion that there are atomic-scale particles that interact with "normal" baryonic matter only via gravity. The problem with WIMPs is that, thus far, not a single one has been detected, despite years of searching for evidence that they exist via multiple, multi-billion-dollar detectors.

With the recent publication of a study of black hole populations in our galaxy (article paywalled, more layman-friendly press release at Phys.org) that indicates there may be as many as 100 million stellar-remnant-type black holes in the Milky Way alone, the question arises, "Is the number of primordial and stellar-remnant black holes in our Universe sufficient to account for the calculated mass of dark matter, without having to invoke WIMPs at all?"

I don't personally have the mathematical knowledge to even begin to answer that question, but I'm curious to find out what the professional cosmologists here think of the idea.

Firefox 55 Arrives With WebVR on Windows, Performance Panel, and Click-to-Play Flash (venturebeat.com) 129

Mozilla today made available a new update to Firefox for Windows to introduce support for WebVR, that the company says, will enable desktop VR users to dive into web-based experiences with ease. Firefox 55 also includes performance panel, faster startup when restoring multiple tabs, a quicker way to search across various search engines, and click-to-play Flash by default. From a report: WebVR is an experimental JavaScript API that provides support for virtual reality devices, such as the HTC Vive, Oculus Rift, and Google Cardboard. As its name implies, the technology is meant for browsers. If you find a web game or app that supports VR, just click the VR goggles icon visible on the web page to experience it using your VR headset. WebVR supports navigating and controlling VR experiences with handset controllers or your movements in physical space. [...] Firefox 55 also allows users to adjust the number of processes and how much resources they want to allocate to any of them. This setting is at the bottom of the General section in Options. In fact, if your computer has more than 8GB of RAM, Mozilla recommends "bumping up the number of content processes that Firefox uses" because it will make Firefox faster, though at the expense of using more memory. In its own tests on Windows 10, the company found that Firefox uses less memory than Chrome, even with eight content processes running.

Android 8.0's 'Streaming OS Updates' Will Work Even If Your Phone Is Full (arstechnica.com) 40

Regardless of whether or not your phone is full of pictures, or videos, or apps, you will still be able to download and install an OS update with Android 8.0. According to the latest source.android.com documentation, Google has cooked up a scheme to make sure that an "insufficient space" error will never stop an update again. Ars Technica reports: Where the heck can Google store the update if your phone is full, though? If you remember in Android 7.0, Google introduced a new feature called "Seamless Updates." This setup introduced a dual system partition scheme -- a "System A" and "System B" partition. The idea is that, when it comes time to install an update, you can normally use your phone on the online "System A" partition while an update is being applied to the offline "System B" partition in the background. Rather than the many minutes of downtime that would normally occur from an update, all that was needed to apply the update was a quick reboot. At that point, the device would just switch from partition A to the newly updated partition B. When you get that "out of space" error message during an update, you're only "out of space" on the user storage partition, which is just being used as a temporary download spot before the update is applied to the system partition. Starting with Android 8.0, the A/B system partition setup is being upgraded with a "streaming updates" feature. Update data will arrive from the Internet directly to the offline system partition, written block by block, in a ready-to-boot state. Instead of needing ~1GB of free space, Google will be bypassing user storage almost entirely, needing only ~100KB worth of free space for some metadata. Ars Technica goes on to note that the feature will be backported to Google Play Services, and will be enabled on "Android 7.0 and later" devices with a dual system partition setup.

Can Elon Musk Be Weaned Off Government Support? (thehill.com) 269

mi shares an opinion piece written by Jenny Beth Martin via The Hill: A study published in 2015 by The Los Angeles Times revealed that just three of Musk's ventures -- SolarCity Corp. (which manufactured and installed solar energy systems before its 2016 merger with Tesla Motors Inc.), Tesla Motors Inc. (which manufactures electric vehicles), and Space Exploration Technologies Corp., known as SpaceX (which builds rocket ships) -- had received $4.9 billion in government subsidies to that point in time. By now, Musk's various ventures have sucked well over $5 billion from government coffers. Worse: in order to induce car buyers to spend their money on electric vehicles, the federal government offers a $7,500 rebate on the purchase price. Some states enhance that rebate with rebates of their own. In California, for instance, purchasers of electric vehicles get a state-funded rebate of $2,500 more.

Slashdot reader mi asks: "Why are you and I subsidizing Elon Musk's products and when will his businesses be able to compete on their own?"

China Built the World's Largest Telescope, But Has No One To Run It (arstechnica.com) 122

An anonymous reader shares a report: China has built a staggeringly large instrument in the remote southern, mountainous region of the country called the Five hundred-meter Aperture Spherical Telescope, or FAST. The telescope measures nearly twice as large as the closest comparable facility in the world, the US-operated Arecibo radio telescope in Puerto Rico. According to the South China Morning Post, the country is looking for a foreigner to run the observatory because no Chinese astronomer has the experience of running a facility of such size and complexity. The Chinese Academy of Sciences began advertising the position in western journals and job postings in May, but so far there have been no qualified applicants. One reason is that the requirements are fairly strict: The candidate must have at least 20 years of previous experience in the field, and he or she must have taken a leading role in large-scale radio telescope project with extensive managerial experience. The candidate must also hold a professorship, or equally senior position, in a world-class research institute or university. Nick Suntzeff, an astronomer at Texas A&M University who helped lead the discovery of dark energy and is involved with construction of the optical Giant Magellan Telescope in Chile, said there are probably about 40 or so astronomers in the world who would qualify for such a job. Compared to other astronomy disciplines, radio astronomy is a relatively small field. "I am sure they will find someone," he said. "But most astronomers in the United States do not like to work abroad. It was hard to get people to apply to work in La Serena, something I could never understand, considering how beautiful it is and how nice the Chilean people are." Among the western community of astronomers there are also questions about the scientific purpose of the FAST telescope. As part of a recent National Science Foundation review of its facilities, US officials placed the similar Arecibo radio telescope near the bottom of its priorities list.

A US Spy Plane Has Been Flying Circles Over Seattle For Days (thedrive.com) 232

turkeydance shares Thursday's report from The Drive: A very unique U.S. Air Force surveillance aircraft has been flying highly defined circles over Seattle and its various suburbs for nine days now... The aircraft, which goes by the callsign "SPUD21" and wears a nondescript flat gray paint job with the only visible markings being a U.S. Air Force serial on its tail, is a CASA CN-235-300 transport aircraft that has been extensively modified... It is covered in a dizzying array of blisters, protrusions, humps and bumps. These include missile approach warning detectors and large fairings on its empennage for buckets of forward-firing decoy flares, as well as both microwave -- the dome antenna behind the wing and flat antenna modification in front of the wing -- and ultra high-frequency satellite communications -- the platter-like antenna behind the dome antenna. A communications intelligence suite also appears to be installed on the aircraft, with the antenna farm on the bottom of its fuselage being a clear indication of such a capability. But what's most interesting is the aircraft's apparent visual intelligence gathering installation...

This particular CN-235, with the serial 96-6042, is one of six that researchers commonly associated with the Air Force's top secret 427th Special Operations Squadron... The 427th occupies the same space with a host of other "black" U.S. military aviation elements, most of which are affiliated to some degree with Joint Special Operations Command and the Intelligence Community... [I]f the military placed the aircraft under civilian control to some degree and with an appropriate legal justification, the U.S. military could possibly fly it in support of a domestic operation or one focused on a foreign suspect or organization operating within the United States... It's also entirely possible, if not probable, that the aircraft could be involved in a realistic training exercise rather than an actual operation... The area could have simply provided a suitable urban area to test existing or new surveillance technologies, too, though this could spark serious privacy concerns if true.

Friday an Air Force Special Operations Command public affairs officer confirmed that the plane was one of theirs, describing its activity as "just a training mission," according to Russia Today.

Celebrate Voyager's 40th Anniversary By Beaming A Message Into Outer Space (nytimes.com) 83

Long-time Slashdot reader Noryungi writes: NASA will celebrate the 40th anniversary of the launch of the twin Voyager probes next month. So let us celebrate both the probes and the people who are still working on them, and nursing them in their final years.
The New York Times fondly profiles Voyager's nine aging flight-team engineers who "may be the last people left on the planet who can operate the spacecraft's onboard computers, which have 235,000 times less memory and 175,000 times less speed than a 16-gigabyte smartphone." NASA reports that now "Voyager 1 is in 'Interstellar space' and Voyager 2 is currently in the 'Heliosheath' -- the outermost layer of the heliosphere where the solar wind is slowed by the pressure of interstellar gas. " But the Times notes that the probes "are running out of fuel. (Decaying plutonium supplies their power.) By 2030 at the latest, they will not have enough juice left to run a single experiment."

NASA is now inviting the public to submit positive messages to be considered for beaming into space on September 5th -- the 40th anniversary of Voyager 1's launch. "Messages can have a maximum of 60 characters and be posted on Twitter, Instagram, Facebook, Google+ or Tumblr using the hashtag #MessageToVoyager," until August 15th, after which humanity will vote on which message should be sent.
