NASA Uploads Hundreds of Rare Aircraft Films to YouTube (gizmodo.com) 37

An anonymous reader shares an article: NASA's Armstrong Flight Research Center is currently in the process of uploading hundreds of extremely rare films to YouTube. And I'd advise you to stop reading if you want to get any work done today. The center has uploaded roughly 300 of the planned 500 films that it will continue to put up over the coming months. And as you can see from the well-populated YouTube channel, they have everything from 1950s experimental aircraft like the X-3 Stiletto to 1960s Lunar Landing Research Vehicle tests (seen in the GIF above) to videos of the time that they intentionally crashed a Boeing 720 in 1984.

SpaceX Pulls the Plug On Its Red Dragon Plans (arstechnica.com) 156

SpaceX has largely confirmed the rumors that the company is no longer planning to send an uncrewed version of its Dragon spacecraft to Mars in 2020, or later. Ars Technica reports: The company had planned to use the propulsive landing capabilities on the Dragon 2 spacecraft -- originally developed for the commercial crew variant to land on Earth -- for Mars landings in 2018 or 2020. Previously, it had signed an agreement with NASA to use some of its expertise for such a mission and access its deep-space communications network. On Tuesday, however, during a House science subcommittee hearing concerning future NASA planetary science missions, Florida Representative Bill Posey asked what the agency was doing to support privately developed planetary science programs. Jim Green, who directs NASA's planetary science division, mentioned several plans about the Moon and asteroids, but he conspicuously did not mention Red Dragon. After this hearing, SpaceX spokesman John Taylor didn't return a response to questions from Ars about the future of Red Dragon. Then, during a speech Wednesday at the International Space Station Research and Development Conference, Musk confirmed that the company is no longer working to land Dragon propulsively for commercial crew.

"Yeah, that was a tough decision," Musk acknowledged Wednesday with a sigh. "The reason we decided not to pursue that heavily is that it would have taken a tremendous amount of effort to qualify that for safety for crew transport," Musk explained Wednesday. "There was a time when I thought the Dragon approach to landing on Mars, where you've got a base heat shield and side mounted thrusters, would be the right way to land on Mars. But now I'm pretty confident that is not the right way." Musk added that his company has come up with a "far better" approach to landing on Mars that will be incorporated into the next iteration of the company's proposed Mars transportation hardware.

US To Create the Independent US Cyber Command, Split Off From NSA (pbs.org) 101

An anonymous reader quotes a report from PBS: After months of delay, the Trump administration is finalizing plans to revamp the nation's military command for defensive and offensive cyber operations in hopes of intensifying America's ability to wage cyberwar against the Islamic State group and other foes, according to U.S. officials. Under the plans, U.S. Cyber Command would eventually be split off from the intelligence-focused National Security Agency. The goal, they said, is to give U.S. Cyber Command more autonomy, freeing it from any constraints that stem from working alongside the NSA, which is responsible for monitoring and collecting telephone, internet and other intelligence data from around the world -- a responsibility that can sometimes clash with military operations against enemy forces. Making cyber an independent military command will put the fight in digital space on the same footing as more traditional realms of battle on land, in the air, at sea and in space. The move reflects the escalating threat of cyberattacks and intrusions from other nation states, terrorist groups and hackers, and comes as the U.S. faces ever-widening fears about Russian hacking following Moscow's efforts to meddle in the 2016 American election.

Scrap Dealer Finds Apollo-Era NASA Computers In Dead Engineer's Basement (arstechnica.com) 104

Long-time Slashdot reader Joe_NoOne quotes Ars Technica: A pair of Apollo-era NASA computers and hundreds of mysterious tape reels have been discovered in a deceased engineer's basement in Pittsburgh... Most of the tapes are unmarked, but the majority of the rest appear to be instrumentation reels for Pioneer 10 and Pioneer 11, NASA's fly-by missions to Jupiter and Saturn... At some point in the early 1970s, an IBM engineer working for NASA at the height of the Space Race took home the computers -- and the mysterious tape reels. A scrap dealer, invited to clean out the deceased's electronics-filled basement, discovered the computers. The devices were clearly labelled "NASA PROPERTY," so the dealer called NASA to report the find. "Please tell NASA these items were not stolen," the engineer's heir told the scrap dealer, according to the report. "They belonged to IBM Allegheny Center Pittsburgh, PA 15212. During the 1968-1972 timeframe, IBM was getting rid of the items so [redacted engineer] asked if he could have them and was told he could have them."
"NASA told the family of the deceased that it was not in the junk removal business," Ars Technica reports, adding "The two computers are so heavy that a crane was likely used to move the machines." A NASA archivist concluded there's no evidence the tapes contained anything of historic significance.

NASA Finally Admits It Doesn't Have the Funding To Land Humans on Mars (arstechnica.com) 247

For years, NASA has been chalking out and expanding its plans to go to Mars. The agency's Journey to Mars project aims to land humans on the red planet during the 2030s. For years, the agency has been reassuring us that it will be able to make do all those audacious projects within the budget it gets. Until now, that is. From a report: Now, finally, the agency appears to have bended toward reality. During a propulsion meeting of the American Institute for Aeronautics and Astronautics on Wednesday, NASA's chief of human spaceflight acknowledged that the agency doesn't really have the funding it needs to reach Mars with the SLS rocket and Orion spacecraft. These vehicles have cost too much to build, and too much to fly, and therefore NASA hasn't been able to begin designing vehicles to land on Mars or ascend from the surface. "I can't put a date on humans on Mars, and the reason really is the other piece is, at the budget levels we described, this roughly 2 percent increase, we don't have the surface systems available for Mars," said NASA's William H. Gerstenmaier, responding to a question about when NASA will send humans to the surface of Mars. "And that entry, descent and landing is a huge challenge for us for Mars." This seems like a fairly common sense statement, but it's something that NASA officials have largely glossed over -- at least in public -- during the agency's promotion of a Journey to Mars.

NASA Releases Juno's First Stunning Close-Ups of Jupiter's Giant Storm (theverge.com) 55

NASA's Juno spacecraft has sent back the first photos from its close flyby over Jupiter's famous Great Red Spot. These images offer the closest ever view of the massive storm. The Verge reports: Juno has been orbiting Jupiter for a little over a year on a mission to study the planet's interior, atmosphere, and magnetosphere. Its elliptical orbit around the planet takes the probe close to the surface for a few hours every 53 days. These are called perijove passes -- and on July 10th, Juno completed its seventh. A little after its closest approach, Juno's camera, JunoCam, snapped a few shots of the storm from about 5,000 miles above. Typically, a team of NASA scientists chooses which images a spacecraft collects on its path around a planet. But with Juno, NASA's opened up the process to the public: space fans can weigh in on the photos JunoCam shoots by ranking their favorite points of interest. After the photos are taken, NASA releases the raw images for the public to process. People can crop them, assemble them into collages, and change or enhance the colors. The results are mesmerizing. You can view even more photos here.

Iceberg the Size of Delaware, Among Biggest Ever Recorded, Snaps Off Antarctica (marketwatch.com) 305

A giant iceberg about the size of Delaware that had been under scientists' watch has broken off from an ice shelf on the Antarctica Peninsula and is now adrift in the Weddell Sea. From a report: The 2,200 square-mile, trillion metric-ton section of the Larsen C ice shelf "calved" off sometime between Monday and Wednesday, a team of researchers at Swansea University's Project MIDAS has reported, citing imaging from NASA's Aqua MODIS satellite instrument. Scientists have tracked the crack for more than a decade and they warned in June that the section was "hanging by a thread." Its break, from Antarctica's fourth-largest ice shelf, changes the border shape of the peninsula forever even though the remaining ice shelf will continue to grow. "The iceberg is one of the largest recorded and its future progress is difficult to predict," said professor Adrian Luckman of Swansea University, lead investigator of the MIDAS project. "It may remain in one piece but is more likely to break into fragments. Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters."

NASA Is Studying the Fungus Among Us Before Humans Take It To a New Planet (fastcompany.com) 60

From a new report: As humanity starts packing for a trip to Mars, NASA scientists are studying what not to bring along for the journey. In short, leave the fungus at home. NASA researchers created a closed habitat -- similar to where humans would have to live to survive long space travel or on a new planet -- and looked at fungi and how they grew, publishing their findings in the journal Microbiome. Fungi are "extremophiles" that can survive in the harshest conditions, but in the closed environment of a space station, they can wreak havoc. To see exactly what kind of fungi might colonize astronauts while they colonize Mars, researchers set up an Inflatable Lunar/Mars Analog Habitat, which simulates the closed environment of the International Space Station. They found that certain kinds of fungi increased in number while humans were living inside the habitat, and the weakened immune systems that come with living in a bubble make people more vulnerable to fungi.

New Sharpened Images From Hubble Telescope Contradict Post-Big Bang Theories (nasa.gov) 98

An anonymous reader quotes NASA: By applying a new computational analysis to a galaxy magnified by a gravitational lens, astronomers have obtained images 10 times sharper than what Hubble could achieve on its own. The results show an edge-on disk galaxy studded with brilliant patches of newly formed stars... The galaxy in question is so far away that we see it as it appeared 11 billion years ago, only 2.7 billion years after the big bang... The resulting reconstructed image revealed two dozen clumps of newborn stars, each spanning about 200 to 300 light-years. This contradicted theories suggesting that star-forming regions in the distant, early universe were much larger, 3,000 light-years or more in size. "There are star-forming knots as far down in size as we can see," said doctoral student Traci Johnson of the University of Michigan, lead author of two of the three papers describing the research.

NASA Seeks Nuclear Power For Mars (scientificamerican.com) 165

New submitter joshtops shares a report from Scientific American: As NASA makes plans to one day send humans to Mars, one of the key technical gaps the agency is working to fill is how to provide enough power on the Red Planet's surface for fuel production, habitats and other equipment. One option: small nuclear fission reactors, which work by splitting uranium atoms to generate heat, which is then converted into electric power. NASA's technology development branch has been funding a project called Kilopower for three years, with the aim of demonstrating the system at the Nevada National Security Site near Las Vegas. Testing is due to start in September and end in January 2018. The last time NASA tested a fission reactor was during the 1960s' Systems for Nuclear Auxiliary Power, or SNAP, which developed two types of nuclear power systems. The first system -- radioisotope thermoelectric generators, or RTGs -- taps heat released from the natural decay of a radioactive element, such as plutonium. RTGs have powered dozens of space probes over the years, including the Curiosity rover currently exploring Mars. The second technology developed under SNAP was an atom-splitting fission reactor. SNAP-10A was the first -- and so far, only -- U.S. nuclear power plant to operate in space. Launched on April 3, 1965, SNAP-10A operated for 43 days, producing 500 watts of electrical power, before an unrelated equipment failure ended the demonstration. The spacecraft remains in Earth orbit.

NASA Is Going To Crash a Satellite Into an Asteroid (fortune.com) 89

The National Aeronautics and Space Administration (NASA) is moving ahead with plans to try out deflection techniques on a passing asteroid to prepare for future, threatening space matter. From a report: The space agency has entered the preliminary design phase for its Double Asteroid Redirection Test (DART). This represents the first trial of what's called the "kinetic impactor technique" of asteroid deflection. Put another way, NASA hopes that by hurling a refrigerator-sized spacecraft at one of the space rocks at a speed roughly nine times that of a bullet, it can knock the asteroid off course and save the Earth. The plan is to launch the first DART satellite at a binary asteroid called Didymos ("Twins"); the twin asteroids are scheduled to pass by earth in 2022 and 2024. (Neither pass poses any threat, according to NASA.) By striking one of the two asteroids, scientists will be able to measure the impact of the collision.

Blue Origin To Build Its BE-4 Rocket Engine In Alabama, Creating Hundreds of Jobs (theverge.com) 53

Blue Origin has recently announced its plans to manufacture the company's new rocket engine, the BE-4, at a state-of-the-art facility in Huntsville, Alabama. According to The Verge, the benefits for Blue Origin are both practical and political. From the report: On the surface, it's a seemingly innocuous decision meant to capitalize on Huntsville's decades-long history of rocket development. The city is home to NASA's Marshall Space Flight Center, where the Saturn V rocket was developed and where NASA's future massive deep-space rocket, the Space Launch System, will also be worked on. Plus, many private space contractors are based in Huntsville, making spaceflight a key part of the city's economy and a huge jobs creator. It's why Huntsville has been nicknamed Rocket City. But the move is most likely motivated by politics as well, given Blue Origin's plans for the BE-4. The company ultimately hopes to use seven BE-4 engines to power its future massive rocket called the New Glenn, which is supposed to launch sometime before 2020. But that's not the only rocket that the BE-4 could fly on. The United Launch Alliance -- a company responsible for launching most of the satellites for the U.S. military -- is developing a new rocket called Vulcan, and it needs new U.S.-made engines for the vehicle. Blue Origin's move to Huntsville will supposedly generate 342 jobs at the new facility, with salaries averaging $75,000, reports The Verge. Given the city's history, the company should have no problem finding aerospace experts in the area. The only problem that could arise would be if ULA doesn't select the BE-4 as the Vulcan's main engine. "ULA is also considering a second option in case the BE-4 doesn't work out: an engine being developed by longtime manufacturer Aerojet Rocketdyne called the AR-1," reports The Verge. "Aerojet is only meant to be Plan B for ULA. But it has one advantage that Blue Origin didn't have until now: it's building its engine in Huntsville, Alabama -- and that comes with some very key political protection."

August Solar Eclipse Could Disrupt Roads and Cellular Networks 95

GeoGreg writes: On August 21, 2017, the contiguous United States will experience its first total solar eclipse since 1979. According to GreatAmericanEclipse.com's Michael Zeiler, approximately 200 million people live within one day's drive of the eclipse. Zeiler projects that between 1.85 to 7.4 million people will attempt to visit the path of totality. As the eclipse approaches, articles are appearing predicting the possibility of automobile traffic jamming rural roads. There is also concern about the ability of rural cellular networks to handle such a large influx. AT&T is bringing in Cell On Wheel (COW) systems to rural locations in Kentucky, Idaho, and Oregon, while Verizon is building a temporary tower in Jackson Hole, Wyoming. The disruption could be frustrating to those trying to get to the eclipse or share their photos via social networking. If cellular networks can't handle the data, apps like Waze won't be much help in avoiding the traffic. If communication is essential near the eclipse path, Astronomy Magazine recommends renting a satellite phone.

Sorry, But Anonymous Has No Evidence That NASA Has Found Alien Life (popsci.com) 166

From a Popular Science article: In a new video, the hacker group known as Anonymous claims that NASA has discovered alien life. But before you freak out, let's talk. Sadly, the group of activists and hacktivists doesn't seem to have found any new evidence to support their extraordinary claim. The video is mainly based on NASA quotes taken out of context, and what appear to be videos and information from conspiracy theory websites. The crux of the argument is based on something Thomas Zurbuchen, NASA's associate administrator for the Science Mission Directorate, said during a hearing in April. These sorts of hearings are organized to educate the House Science Committee on the latest research in a particular field of study. During this one, Zurbuchen said: "Taking into account all of the different activities and missions that are specifically searching for evidence of alien life, we are on the verge of making one of the most profound, unprecedented, discoveries in history." That's the quote Anonymous is pegging their video on. But if you watch his opening statement, he actually explains his reasoning just before he gets to that part. He mentions the Mars 2020 rover, which will look for signs of past life on the red planet. The Europa Clipper mission is slated to search for conditions suitable to life on Jupiter's ocean-filled moon. In a statement, Zurbuchen said, "While we're excited about the latest findings from NASA's Kepler space observatory, there's no pending announcement regarding extraterrestrial life. For years NASA has expressed interest in searching for signs of life beyond Earth. We have a number of science missions that are moving forward with the goal of seeking signs of past and present life on Mars and ocean worlds in the outer solar system. While we do not yet have answers, we will continue to work to address the fundamental question, 'are we alone?'"

SpaceX Livestreams Sunday's Rocket Launch (space.com) 74

An anonymous reader quotes Space.com: A SpaceX Falcon 9 rocket carrying the 10 satellites for Iridium Communications is scheduled to liftoff from Vandenberg Air Force Base in California at 1:25 p.m. PDT (4:25 p.m. EDT/2025 GMT). The live webcast is expected to begin about 1 hour before the opening of the launch window, and you can watch it on SpaceX's website, or at Space.com. This is the second of eight planned Iridium launches with SpaceX. The launches will deliver a total of 75 satellites into space for the $3 billion Iridium NEXT global communications network. "Iridium NEXT will replace the company's existing global constellation in one of the largest technology upgrades ever completed in space," according to a statement from Iridium. "It represents the evolution of critical communications infrastructure that governments and organizations worldwide rely upon to drive business, enable connectivity, empower disaster relief efforts and more."
After the mission the booster rocket will attempt to land on a droneship. The droneships name is "Just Read The Instructions."

Gwyneth Paltrow's Goop $120 'Bio-Frequency Healing' Sticker Packs Get Shot Down by NASA (fastcompany.com) 214

From a report: Goop had claimed the costly "Body Vibes" stickers were "made with the same conductive carbon material NASA uses to line space suits so they can monitor an astronaut's vitals during wear" and because of that were able to "target imbalances" of the human body's energy frequencies when they get thrown out of whack, reports Gizmodo. The thing is, NASA confirmed to Gizmodo that they "do not have any conductive carbon material lining the spacesuits" of astronauts.

Curiosity Rover Decides, By Itself, What To Investigate On Mars (sciencemag.org) 73

sciencehabit writes: NASA's Curiosity rover landed on Mars in 2012, in part to analyze rocks to see whether the Red Planet was ever habitable (or inhabited). But now the robot has gone off script, picking out its own targets for analysis -- precisely as planned. Last year, NASA scientists uploaded a piece of software called Autonomous Exploration for Gathering Increased Science (AEGIS) adapted from the older Opportunity rover. Curiosity can now scan each new location and use artificial intelligence to find promising targets for its ChemCam. Compared with the estimated 24% success rate of random aiming at picking out outcrops -- a prime target for investigation -- the current version of AEGIS lets the rover find them 94% of the time, researchers report.

NASA Finds Evidence Of 10 New Earth-sized Planets (usatoday.com) 63

NASA said Monday it has found new evidence of 219 planets outside our Solar System. Ten of those exoplanets appear to be similar to the size of the Earth and orbit their stars in the habitable zone. From a report: The new planets' existence must still be double-checked. But Kepler's latest haul -- which includes a planet that is only slightly larger than Earth and receives the same amount of energy from its sun as Earth -- is the latest triumph for Kepler, which has spotted roughly 80 percent of the planets orbiting stars other than our sun. Because of their potential for hosting life, the 10 Earth-size planets are the most glamorous of the newly announced planets from Kepler. But those 10 were joined by an additional 209 more garden-variety planets that are unlikely to be hospitable to life because they are too gassy, too hot, too cold or otherwise unlike the only known planet to host life: Earth.

Google Fights Bay Area Housing Prices With Pre-Fab Housing (siliconvalley.com) 304

An anonymous reader quotes the Bay Area Newsgroup: With rental costs skyrocketing and homes out of reach for many, Google has hit on a solution that may help it attract workers to the crushingly expensive Bay Area. The tech giant plans to buy 300 units of modular housing to serve as temporary employee accommodations on its planned "Bay View" campus at NASA's Moffett Field, according to a source familiar with the plan. Experts heralded the move as not only good for Google, but as a potential template for others to follow as the high cost of construction combined with expensive real estate make affordable housing hard to come by... Modular housing has the potential to be "a real game changer" for the Bay Area housing crunch, said Matt Regan, senior vice-president of public policy at the Bay Area Council, a business group of which Google is a member...

The Bay Area boasts many sites suitable for modular rental housing, undeveloped so far largely because the cost of traditional building is too high for the rent the facilities could generate, Regan said. With prefab housing costing up to 50 percent less, "all of a sudden sites like that become economically feasible to develop," Regan said.

Air Force Budget Reveals How Much SpaceX Undercuts Launch Prices (arstechnica.com) 97

An anonymous reader quotes a report from Ars Technica: In 2014, the U.S. Government Accountability Office issued a report on cost estimates for the U.S. Air Force's program to launch national security payloads, which at the time consisted of a fleet of rockets maintained and flown entirely by United Launch Alliance (ULA). The report was critical of the non-transparent nature of ULA's launch prices and noted that the government "lacked sufficient knowledge to negotiate fair and reasonable launch prices" with the monopoly. At around the same time, the new space rocket company SpaceX began to aggressively pursue the opportunity to launch national security payloads for the government. SpaceX claimed to offer a substantially lower price for delivering satellites into various orbits around Earth. But because of the lack of transparency, comparing prices was difficult. The Air Force recently released budget estimates for fiscal year 2018, and these include a run out into the early 2020s. For these years, the budget combines the fixed price rocket and ELC contract costs into a single budget line. (See page 109 of this document). They are strikingly high. According to the Air Force estimate, the "unit cost" of a single rocket launch in fiscal year 2020 is $422 million, and $424 million for a year later. SpaceX sells basic commercial launches of its Falcon 9 rocket for about $65 million. But, for military launches, there are additional range costs and service contracts that add tens of millions of dollars to the total price. It therefore seems possible that SpaceX is taking a loss or launching at little or no profit to undercut its rival and gain market share in the high-volume military launch market. Elon Musk retweeted the article, adding "$300M cost diff between SpaceX and Boeing/Lockheed exceeds avg value of satellite, so flying with SpaceX means satellite is basically free."
