SpaceX Launches NASA's Planet-Hunting Satellite, Successfully Lands Its Falcon 9 Rocket (theverge.com) 37

SpaceX launched NASA's TESS spacecraft Wednesday evening from Cape Canaveral, Florida, and successfully landed its Falcon 9 rocket on a drone ship following takeoff. This marks 24 successful landings for SpaceX now, notes The Verge. We will update this post once TESS is deployed into orbit. From the report: TESS is NASA's newest exoplanet hunter. The probe is tasked with staring at stars tens to hundreds of light-years from Earth, watching to see if they blink. When a planet passes in front of a distant star, it dims the star's light ever so slightly. TESS will measure these twinkles from a 13.7-day orbit that extends as far out as the distance of the Moon. The satellite won't get to its final orbit on this launch. Instead, the Falcon 9 will put TESS into a highly elliptical path around Earth first. From there, TESS will slowly adjust its orbit over the next couple of months by igniting its onboard engine multiple times. The spacecraft will even do a flyby of the Moon next month, getting a gravitational boost that will help get the vehicle to its final path around Earth. Overall, it will take about 60 days after launch for TESS to get to its intended orbit; science observations are scheduled to begin in June.

NASA's Got a Plan For a 'Galactic Positioning System' To Save Astronauts Lost in Space (space.com) 102

From a report: Outer space glows with a bright fog of X-ray light, coming from everywhere at once. But peer carefully into that fog, and faint, regular blips become visible. These are millisecond pulsars, city-sized neutron stars rotating incredibly quickly, and firing X-rays into the universe with more regularity than even the most precise atomic clocks. And NASA wants to use them to navigate probes and crewed ships through deep space. A telescope mounted on the International Space Station (ISS), the Neutron Star Interior Composition Explorer (NICER), has been used to develop a brand new technology with near-term, practical applications: a galactic positioning system, NASA scientist Zaven Arzoumanian told physicists Sunday (April 15) at the April meeting of the American Physical Society.

With this technology, "You could thread a needle to get into orbit around the moon of a disant planet instead of doing a flyby," Arzoumian told Live Science. A galactic positioning system could also provide "a fallback, so that if a crewed mission loses contact with the Earth, they'd still have navigation systems on board that are autonomous." Right now, the kind of maneuvers that navigators would need to put a probe in orbit around distant moons are borderline impossible.

Diamonds in Sudan Meteorite 'Are Remnants of Lost Planet' (theguardian.com) 43

Diamonds found in a meteorite that exploded over the Nubian desert in Sudan a decade ago were formed deep inside a "lost planet" that once circled the sun in the early solar system, scientists say. From a report: Microscopic analyses of the meteorite's tiny diamonds revealed they contain compounds that are produced under intense pressure, suggesting the diamonds formed far beneath the surface of a planet. In this case, the mysterious world was calculated to be somewhere between Mercury and Mars in size. Astronomers have long hypothesised that dozens of fledgling planets, ranging in size from the moon to Mars, formed in the first 10m years of the solar system and were broken apart and repackaged in violent collisions that ultimately created the terrestrial planets that orbit the sun today.

NASA May Fly Humans On the Less Powerful Version of Its Deep-Space Rocket (theverge.com) 27

An anonymous reader quotes a report from The Verge: NASA may make some big changes to the first couple flights of its future deep-space rocket, the Space Launch System, after getting a recent funding boost from Congress to build a new launch platform. When humans fly on the rocket for the first time in the 2020s, they might ride on a less powerful version of the vehicle than NASA had expected. If the changes move forward, it could scale down the first crewed mission into deep space in more than 45 years. The SLS has been in development for the last decade, and when complete, it will be NASA's main rocket for taking astronauts to the Moon and Mars. NASA has long planned to debut the SLS with two crucial test missions. The first flight, called EM-1, will be uncrewed, and it will send the smallest planned version of the rocket on a three-week long trip around the Moon. Three years later, NASA plans to launch a bigger, more powerful version of the rocket around the Moon with a two-person crew -- a mission called EM-2.

But now, NASA may delay that rocket upgrade and fly the same small version of the SLS for the crewed flight instead. If that happens, NASA would need to come up with a different type of mission for the crew to do since they won't be riding on the more powerful version of the vehicle. "If EM-2 flies that way, we would have to change the mission profile because we can't do what we could do if we had the [larger SLS]," Robert Lightfoot, NASA's acting administrator, said during a Congressional hearing yesterday. NASA clarified that astronauts would still fly around the Moon on the second flight. However, the rocket would not be able to carry extra science payloads as NASA had originally planned. "The primary objective for EM-2 is to demonstrate critical functions with crew aboard, including mission planning, system performance, crew interfaces, and navigation and guidance in deep space, which can be accomplished on a Block 1 SLS," a NASA spokesperson said in a statement to The Verge.

IETF Approves TLS 1.3 As Internet Standard (bleepingcomputer.com) 84

An anonymous reader writes: The Internet Engineering Task Force (IETF), the organization that approves proposed Internet standards and protocols, has formally approved TLS 1.3 as the next major version of the Transport Layer Security (TLS) protocol. The decision comes after four years of discussions and 28 protocol drafts, with the 28th being selected as the final version. TLS 1.3 is now expected to become the standard method in which a client and server establish an encrypted communications channel across the Internet -- aka HTTPS connections.

The protocol has several advantages over its previous version -- TLS 1.2. The biggest feature is that TLS 1.3 ditches older encryption and hashing algorithms (such as MD5 and SHA-224) for newer and harder to crack alternatives (such as ChaCha20, Poly1305, Ed25519, x25519, and x448). Second, TLS 1.3 is also much faster at negotiating the initial handshake between the client and the server, reducing the connection latency that many companies cited when justifying not supporting HTTPS over HTTP.

Browsers like Chrome, Edge, Firefox, and Pale Moon have already rolled out support for earlier versions of the TLS 1.3 draft, and are now expected to update this support to the official standard.

Sex Workers Say Porn On Google Drive Is Suddenly Disappearing (vice.com) 356

An anonymous reader quotes a report from Motherboard: Porn performer Avey Moon was trying to send the lucky winner of her Chaturbate contest his prize -- one of her videos, titled "POV Blowjob" -- through her Google Drive account. But it wouldn't send, and Google wasn't telling her why. "I thought there was something wrong with my file and I got rather worried," Moon told me in a Twitter message. "I had promised this guy his content and he was so good to me. I was panicked because I thought if I couldn't give him his prize, he would feel like he got ripped off and never come back again or worse, he could actually file a complaint with Chaturbate about me and they can take money from me." She's not alone. Six porn performers I talked to and more on social media said that they suddenly can't download adult content they keep on Google Drive. They also said they can't a share that content with other accounts or send to clients. In some cases, the adult content is disappearing from Drive without warning or explanation. The porn performers I talked to started sounding the alarm on Twitter last week. They said that Google Drive no longer seemed sex-trade friendly, detailing error messages and sharing cloud storage alternatives with each other.

When I asked about sexual content being blocked on Drive, a spokesperson for Google directed me to the Drive policy page -- specifically the section on sexually explicit material, which says, "Do not publish sexually explicit or pornographic images or videos.... Additionally, we do not allow content that drives traffic to commercial pornography." Writing about porn and sex is permitted, the policy states, as long as it's not accompanied by sexually explicit images or videos. According to Google, Drive uses a combination of automated systems and manual review to decide what's in violation.
One worker said they've been using Google Drive for most of the last five and a half years but just recently received an error message when sending a video, saying that the item may violate Google's Terms of Service, with a link to request a review. In this case, the video title was explicit, but other adult performers report similar messages when sending content with non-explicit titles. "Some sex workers are wondering if this has something to do with the impending vote on the SESTA-FOSTA bill," reports Motherboard. We now have learned that the Senate has passed the bill.

YouTube Kids Has Videos on How Reptilians Rule the World, Moon Landing Was Fake (gizmodo.com) 258

An anonymous reader shares a report: YouTube Kids, the supposedly child-friendly version of YouTube that's been shown to often play host to troves of slop content and disturbing videos, apparently was showing videos from British conspiracy theorist David Icke, a guy who believes reptilian aliens secretly control the world and are responsible for the Holocaust. According to a Saturday report in Business Insider, searching for the term "UFO" on YouTube kids turned up a video purporting "to show a UFO shooting at a chemtrail." The suggested followups for that video featured a number of Icke's clips, including a nearly five-hour lecture on how aliens built the pyramids and secretly run the planet through a ruling class extraterrestrial-human hybrids. The video also delves into a number of other conspiracy theories, including claims Freemasons indulge in human sacrifice and President John F. Kennedy was assassinated by his own government.

According to Business Insider, "Two other conspiracy theory videos by Icke appeared in the related videos, meaning it was easy for children to quickly go from watching relatively innocent videos about toys to conspiracy content." Searching for the term "moon landing" also resulted in a number of conspiratorial videos emerging, including one making the claim that CERN's Large Hadron Collider had opened a portal to another world that an unfortunate employee then vanished in.

YouTube Will Add Information From Wikipedia To Videos About Conspiracies (theverge.com) 226

An anonymous reader quotes a report from The Verge: YouTube will add information from Wikipedia to videos about popular conspiracy theories to provide alternative viewpoints on controversial subjects, its CEO said today. YouTube CEO Susan Wojcicki said that these text boxes, which the company is calling "information cues," would begin appearing on conspiracy-related videos within the next couple of weeks. Wojcicki, who spoke Tuesday evening at a panel at the South by Southwest Interactive festival in Austin, showed examples of information cues for videos about the moon landing and chemtrails. "When there are videos that are focused around something that's a conspiracy -- and we're using a list of well-known internet conspiracies from Wikipedia -- then we will show a companion unit of information from Wikipedia showing that here is information about the event," Wojcicki said. The information cues that Wojcicki demonstrated appeared directly below the video as a short block of text, with a link to Wikipedia for more information. Wikipedia -- a crowdsourced encyclopedia written by volunteers -- is an imperfect source of information, one which most college students are still forbidden from citing in their papers. But it generally provides a more neutral, empirical approach to understanding conspiracies than the more sensationalist videos that appear on YouTube.

Nokia, Vodafone To Bring 4G To the Moon (reuters.com) 80

According to Reuters, the moon will get its first mobile phone network next year, enabling high-definition streaming from the landscape back to earth. "Vodafone Germany, network equipment maker Nokia and carmaker Audi said on Tuesday they were working together to support the mission, 50 years after the first NASA astronauts walked on the moon." From the report: Vodafone said it had appointed Nokia as its technology partner to develop a space-grade network which would be a small piece of hardware weighing less than a bag of sugar. The companies are working with Berlin-based company PTScientists on the project, with a launch scheduled in 2019 from Cape Canaveral on a SpaceX Falcon 9 rocket, Vodafone said. One executive involved said the decision to build a 4G network rather than a state-of-the-art 5G network was taken because the next generation networks remain in the testing and trial stage and are not stable enough to ensure they would work from the lunar surface.

Microbes Found in Earth's Deep Ocean Might Grow on Saturn's Moon Enceladus (theverge.com) 69

Life as we know it needs three things: energy, water and chemistry. Saturn's icy moon Enceladus has them all, as NASA spacecraft Cassini confirmed in the final years of its mission to that planet. From a report: Scientists have successfully cultivated a few of these tiny organisms in the lab under the same conditions that are thought to exist on the distant moon, opening up the possibility that life might be lurking under the world's surface. Enceladus is one of the most intriguing places in the Solar System since it has many crucial ingredients needed for life to thrive. For one, it has lots of water. NASA's Cassini spacecraft -- which explored the Saturn system from 2004 to 2017 -- found that plumes of gas and particles erupt from the south pole of Enceladus, and these geysers stem from a global liquid water ocean underneath the moon's crust. Scientists think that there may be hot vents in this ocean, too -- cracks in the sea floor where heated rock mingles with the frigid waters. This mixing of hot and cold material seems to be creating a soup of chemical compounds that might support life.

SpaceX Successfully Lands Two Falcon Heavy Boosters Simultaneously After Rocket Launch [Update] (spaceflightnow.com) 446

After nearly a decade of development, SpaceX's Falcon Heavy rocket has successfully launched from pad 39A at NASA's Kennedy Space Center in Florida today. After reaching orbit, the two side boosters simultaneously landed at Landing Zone One. We do not know the status of the central core of the rocket, which was destined to land on the "Of Course I Still Love You" drone ship roughly 8:19 minutes into the flight.

According to Space.com, the Falcon Heavy is the most powerful rocket to launch since NASA's Saturn V -- the iconic vessel that, with 7.5 million pounds of thrust, accomplished the definitive Apollo-era feat of putting astronauts on the moon. Elon Musk says that Falcon Heavy is "twice as powerful as any other booster operating today." As for the payload, it includes a Tesla Roadster electric car. "The Falcon Heavy will send the vehicle around the sun in an elliptical orbit that will extend farther than Mars' orbit," reports Space.com.

UPDATE: SpaceX has confirmed The Verge's reporting that the middle core of SpaceX's Heavy Rocket missed the drone ship where it was supposed to land. "The center core was only able to relight one of the three engines necessary to land, and so it hit the water at 300 miles per hour," reports The Verge. "Two engines on the drone ship were taken out when it crashed, SpaceX CEO Elon Musk said in a press call after the rocket launch. It's a small hiccup in an otherwise successful first flight."

Scientists May Have Discovered the First Planets Outside the Milky Way (washingtonpost.com) 74

Using data from a NASA X-ray laboratory in space, Xinyu Dai, an astrophysicist and professor at the University of Oklahoma, detected a population of planets beyond the Milky Way galaxy (Warning: source may be paywalled; alternative source). The planets range in size from Earth's moon to the massive Jupiter. From the report: There are few methods to determine the existence of distant planets. They are so far away that no telescope can observe them, Dai told The Washington Post. So Dai and postdoctoral researcher Eduardo Guerras relied on a scientific principle to make the discovery: Albert Einstein's theory of relativity. Einstein's theory suggests light bends when tugged by the force of gravity. In this case, the light is coming from a quasar -- the nucleus of a galaxy with a swirling black hole -- that emits powerful radiation in the distance. Between that quasar and the space-based laboratory is the galaxy of newly discovered planets. The gravitational force of the galaxy bends the light heading toward the Milky Way, illuminating the galaxy in an effect called microlensing. In that way, the galaxy acts as a magnifying glass of sorts, bringing a previously unseen celestial body into X-ray view. In a university news release, Guerras had a less formal way to describe the complicated process: "This is very cool science."

How To Watch the 'Super Blue Blood Moon' Lunar Eclipse (livescience.com) 90

Stephanie Pappas reports via Live Science how you can watch Wednesday's "Super Blue Blood Moon" eclipse: The eclipse will occur in the wee hours of the morning on Wednesday, Jan. 31, when the full moon will pass through the Earth's shadow. Viewers on Earth will see the face of the moon turn a murky red. On the West Coast, totality (the full shading of the moon) will occur at 4:51 a.m. PST until 6:08 a.m. PST. Before that, the moon will enter the outer portion of the Earth's shadow, or penumbra, at 2:51 a.m. PST. The real show will become visible starting at 3:48 a.m. PST, when the moon will be entering the umbra, or central portion of Earth's shadow, and a dark shadow will move over the face of the moon. The moon will leave the umbra at 7:11 a.m. PST. East Coasters can catch the partial lunar eclipse before dawn, but they will miss totality because the moon will have set below the horizon by 7:06 a.m. EST. To see the shadow of the Earth become visible on the moon's face, look up at 6:31 a.m. EST; by 6:48 a.m. EST, the moon will be entering the umbra, or central portion of the shadow, which should make the color change more apparent.

For viewers in the Central and Mountain time zones, the moon will set either during the total eclipse or while the satellite is exiting the Earth's shadow. The moon enters the dark umbra at about 5:48 a.m. CST and will hit totality slightly before moonset, at 6:51 a.m. CST. The umbra will appear at 4:48 a.m. MST, and the moon will enter totality at 5:51 a.m. MST. Viewers in the Mountain time zone will also get the chance to see the middle of totality, when the moon is up to 100,000 times fainter than usual, at 6:29 a.m. The eclipse will end slightly before moonset, at 7:07 a.m. MST. Viewers in Alaska and Hawaii will get a full dose of totality, too, but they'll have to be very early birds or night owls. Totality begins at 3:51 a.m. AKST and ends at 5:05 a.m. AKST. Totality hits at 2:51 a.m. HST and will be over by 4:05 a.m. HST.

Official: No One Is Going To Win the Google Lunar X Prize Competition (theverge.com) 33

The X Prize Foundation announced today that no one is going to win the foundation's competition to send a spacecraft to the Moon. "Only five finalists remained in the Google-sponsored Lunar X Prize competition, and in order to win any grand prize money, the teams had to launch and complete their missions to the Moon before March 31st, 2018," reports The Verge. "But with only two months until the deadline, no team is ready to launch, so Google will keep the prize money instead." From the report: The Google Lunar X Prize was established in 2007 as a way to help lower the cost of getting to space. So far, only government agencies have landed on the lunar surface, with missions that have cost many millions and even billions of dollars. That's why the X Prize Foundation, which sets up global competitions, challenged teams with developing and launching robotic lunar landers using mostly private funding. The idea was to make them come up with creative methods for getting to the Moon on the cheap. Landing on the lunar surface was only part of the challenge. Teams had to travel up to 1,640 feet (500 meters) on the Moon too, as well as do live broadcasts. The first to fulfill all these requirements before the deadline would receive $20 million, while the second place team would get $5 million. Other smaller purses would be awarded to teams that did special tasks, such as completing an orbit around the Moon before landing. "As a result of this competition, we have sparked the conversation and changed expectations with regard to who can land on the Moon," the X Prize Foundation said in its statement. "Many now believe it's no longer the sole purview of a few government agencies, but now may be achieved by small teams of entrepreneurs, engineers, and innovators from around the world." A Google spokesperson also told CNBC that the company is "thrilled with the progress made by these teams over the last ten years."

Google's $20 Million Race To the Moon Will End With No Winner -- and Google is OK With That (cnbc.com) 85

Michael Sheetz, reporting for CNBC: More than ten years after it was announced -- and extended over and over -- the Google-sponsored race to win $20 million by landing on the moon will end with no winners. The four teams racing to win the Google Lunar Xprize, which requires a company to land a spacecraft on the moon by March 31, are either short of money or unable to launch this year, three people familiar with the matter told CNBC. Meanwhile, Google -- which extended the deadline from 2012 to 2014 and then eventually to 2018 -- is not willing to push out the date further. "Google does not have plans at this time to extend the deadline again, however we are so thrilled with the progress made by these teams over the last ten years," a Google spokesperson said in a statement to CNBC. The commercial space industry has written off the Lunar Xprize as improbable, and not worth pursuing, according to sources.

Rocket Lab Successfully Reaches Orbit and Deploys Its First Satellites (geekwire.com) 64

Long-time Slashdot reader ClarkMills writes: Rocket Lab has successfully launched its second Electron rocket from New Zealand's Mahia Peninsula, with the rocket reaching orbit for the first time... This follows the company's first launch last May, in which the rocket got to space but did not make it to orbit after range safety officials had to kill the flight.
Just 60 seconds before lift-off yesterday, a "rogue ship" entered their launch-range area, prompting them to postpone the launch until today. GeekWire reports: This mission was nicknamed "Still Testing," but unlike the first mission, the objective was not merely to test Rocket Lab's hardware. The rocket had the additional task of putting three nanosatellites in orbit: an Earth-imaging Dove satellite for Planet, and two Lemur-2 satellites that the Spire space venture would use for tracking ships and monitoring weather... The price tag for a mission is as low as $5 million, thanks to streamlined hardware production techniques. The Electron makes use of carbon composite materials for its rocket core, and 3-D printing techniques for its Rutherford rocket engines.
90 minutes ago Spire tweeted that they'd experienced a "good clean deployment" of their satellites, adding that they were already receiving images and calling it "a huge win" for commercial space, small satellites, the Electron rocket, and New Zealand.

US Tests Nuclear Power System To Sustain Astronauts On Mars (reuters.com) 197

Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface on Mars have been successful and a full-power run is scheduled for March, officials said on Thursday. Reuters reports: National Aeronautics and Space Administration and U.S. Department of Energy officials, at a Las Vegas news conference, detailed the development of the nuclear fission system under NASA's Kilopower project. Months-long testing began in November at the energy department's Nevada National Security Site, with an eye toward providing energy for future astronaut and robotic missions in space and on the surface of Mars, the moon or other solar system destinations. A key hurdle for any long-term colony on the surface of a planet or moon, as opposed to NASA's six short lunar surface visits from 1969 to 1972, is possessing a power source strong enough to sustain a base but small and light enough to allow for transport through space. NASA's prototype power system uses a uranium-235 reactor core roughly the size of a paper towel roll. The technology could power habitats and life-support systems, enable astronauts to mine resources, recharge rovers and run processing equipment to transform resources such as ice on the planet into oxygen, water and fuel. It could also potentially augment electrically powered spacecraft propulsion systems on missions to the outer planets.

Bitcoin Watchers Running Out of Explanations Blame Slump on Moon (bloomberg.com) 157

If regulatory concerns aren't enough to explain Bitcoin's 50 percent slump from its record high reached last month, how about blaming it on the moon? An anonymous reader writes: The Lunar New Year, which marks the first day of the year in the Chinese calendar, is being cited by some as contributing to Bitcoin's slump as Asian traders cash out their cryptocurrencies to travel and buy gifts for the holiday that starts Feb. 16 this year. The festivity is celebrated not just in China, but in other Asian countries including Singapore, Indonesia, Malaysia, Korea and Thailand. "The January drop is a recurring theme in cryptocurrencies as people celebrating the Chinese New Year, aka Lunar New Year, exchange their crypto for fiat currency," said Alexander Wallin, chief executive officer of trading social network SprinkleBit in New York. "The timing is about four to six weeks before the lunar year, when most people make their travel arrangements and start buying presents."

Japan's Latest Sensation is a Cryptocurrency Pop Group (engadget.com) 57

An anonymous reader quotes Engadget: If you're starting a pop group in Japan, where giant rosters and virtual superstars are par for the course, how do you stand out? By tying yourself to something trendy -- and in 2018, that means cryptocurrency. Meet Kasotsuka Shojo (Virtual Currency Girls), a J-pop group where each of the eight girls represents one of the larger digital monetary formats. Yes, you're supposed to cheer for bitcoin or swoon over ethereum (what, no litecoin?). The group played its first concert on January 12th, and naturally you had to pay in cryptocurrency to be one of the few members of the general public to get in. The group's first single, "The Moon and Virtual Currencies and Me," warns listeners about the perils of fraud and extols the virtues of good online security.
"It isn't clear how French maid outfits symbolize cryptocurrency or blockchain technology," notes Quartz, "but they're popular costumes in Japan's anime and cosplay circles."

Scientists Think They've Discovered Lava Tubes Leading To the Moon's Polar Ice (sciencealert.com) 59

schwit1 quotes ScienceAlert: Small pits in a large crater on the Moon's North Pole could be "skylights" leading down to an underground network of lava tubes -- tubes holding hidden water on Earth's nearest neighbour, according to new research. There's no lava in them now of course, though that's originally how the tubes formed in the Moon's fiery past. But they could indicate easy access to a water source if we ever decide to develop a Moon base sometime in the future.

Despite the Moon's dry and dusty appearance, scientists think it contains a lot of water trapped as frozen ice. What these new observations carried out by NASA's Lunar Reconnaissance Orbiter (LRO) show is that it might be much more accessible than we thought... Scientists have long been thinking about how to extract the ice reserves we think are up there -- solar power was originally out of the question, as it's the freezing shadowed areas of the Moon that have preserved the ice in the first place. Not only would natural skylights like these provide easier access to the underground ice, it would also mean solar power would be back on the table as an idea.
