An anonymous reader writes: A campaign taking shape in Brazil seeks to fight online harassment in an unusual way: by posting the abusive comments on real billboards. "The group collects comments from Facebook or Twitter and uses geolocation tools to find out where the people who have posted them live. They then buy billboard space nearby and post the comments in huge letters, although names and photos are pixelated." Brazil has laws prohibiting racial abuse, but this group doesn't think the government is doing enough to stop it. The campaign's founder said, "Those people [who post abuse online] think they can sit in the comfort of their homes and do whatever they want on the internet. We don't let that happen. They can't hide from us, we will find them."
Taco Cowboy writes with news that Penn State researchers have discovered a way to produce ultra-thin diamond nanothreads that could be ideal for a space elevator. According to the report at Space.com, The team, led by chemistry professor John Badding, applied alternating cycles of pressure to isolated, liquid-state benzene molecules and were amazed to find that rings of carbon atoms assembled into neat and orderly chains. While they were expecting the benzene molecules to react in a disorganized way, they instead created a neat thread 20,000 times smaller than a strand of human hair but perhaps the strongest material ever made. ... Just recently, a team from the Queensland University of Technology in Australia modeled the diamond nanothreads using large-scale molecular dynamics simulations and concluded that the material is far more versatile than previously thought and has great promise for aerospace properties.
MarkWhittington writes: The Commercial Space Launch Act, which includes provisions allowing American companies the right to keep resources that they mine in space, was recently signed into law by President Barack Obama. While the act has been hailed as groundbreaking in the United States, the space mining title has gotten an angry reaction overseas. In an article in Science Alert, Gbenga Oduntan, Senior Lecturer in International Commercial Law, University of Kent, condemned the space mining provisions as environmentally risky and a violation of international law. Ram Jakhu, a professor at Canada's McGill University's Institute of air and space law, adds that space mining is a violation of the Outer Space Treaty and should not be allowed.
StartsWithABang writes: One of the most important characteristics of a planet, at least according to the IAU definition, is that it clear its orbit of all other bodies. But if we allowed for a special caveat — the possibility of two similarly-sized objects sharing the same orbit — could we have a stable configuration where that occurred? Surprisingly, not only is the answer yes, but there are three ways to do it: to have one at the L4/L5 Lagrange point of the other, to have a close-orbiting binary planet, or to have orbit-swapping worlds, where they periodically change spots with one another. Unbelievably, our Solar System has a history of all three!
MarkWhittington writes: As NASA has noted, the space agency and its contractors are working diligently on the first launch of the heavy-lift Space Launch System. The launch, officially called EM-1, or Exploration Mission 1, will loft an unpiloted version of the Orion spacecraft around the moon. NASASpaceFlight.com also noted that a number of secondary payloads, known as CubeSats, will be along for the ride as well. NASA considered EM-1, scheduled for 2018, a crucial step in its Journey to Mars which will, it is hoped, reach its ultimate destination sometime in the 2030s.
RockDoctor writes with news as reported by the BBC that parts of a Falcon 9 launcher have washed ashore on the Isles of Scilly off the SW coast of Britain. Early impressions are that the pieces are from the failed Falcon 9 ISS launch which exploded after take-off in June. That's not the only possibility, though; according to the article, However Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, said many experts believed, due to the size and markings which have now been revealed, it was from a different mission. "All the geeks have been getting together and looking at fine details, and we're pretty sure it's a launch from September 2014 that successfully sent a cargo mission to the space station. "It didn't look like an exploded rocket to me, it looked like a fairly normal piece of space junk when the lower stage of a rocket falls from a hundred miles up and hits the ocean. Large sections can remain in tact and it's really quite normal," he said.
New submitter AppleHoshi writes: The BBC is reporting that a large chunk of the SpaceX Falcon-9 rocket, which exploded shortly after take-off from Cape Canaveral earlier this year, has been found 4,000 miles away, in the sea off the Isles of Scilly. The recovered section is approximately 10m (32ft) by 4m (13ft). It was discovered by a local coastguard patrol, though they didn't recognize it until they scraped off a layer of goose barnacles.
MarkWhittington writes: Back in October, findings from the Kepler Space Telescope suggested that something strange was going on around a star called KIC 8462852. Kepler was built to detect exoplanets by measuring the cycles of dimming light from other stars, indicating that a large object was passing between them and Earth. But the dimming light cycle from KIC 8462852 seemed to suggest a lot of smaller objects swarming around it. Scientists narrowed down the explanations to either a swarm of comets or alien megastructures. NASA announced evidence garnered by two other telescopes that pointed to the comet explanation.
judgecorp writes: The government-owned Russian energy company Rosenergoatom is building Russia's largest data center at its giant Kalinin nuclear power station. Most of the space will be available to customers, and the facility expects to be in demand, thanks to two factors: reliable power, and the data residency rules which require Russian citizens' data to be located within Russia. Facebook and Google don't have data centers within Russia yet — and Rosenergoatom has already invited them into the Kalinin facility.
schwit1 writes: Using its H-IIA rocket, upgraded to lower cost, Japan launched its first commercial payload today, putting Canada's Telestar 12V into geosynchronous orbit. UPI reports: "Japan's Aerospace Exploration Agency said the H-IIA rocket was upgraded for the launch, permitting the satellite to stay closer to its geostationary orbit. Tokyo's Chief Cabinet Secretary Yoshihide Suga said he hoped the launch would exhibit the quality of Japan's rocket engineering, and that the successful launch would result in more orders from other global corporations. Following the launch, Mitsubishi Heavy Industries vice president Naohiko Abe said the firm plans to actively promote the H-IIA for satellite launches."
MarkWhittington writes: In an interview published in The Verge, celebrity astrophysicist and media personality Neil deGrasse Tyson touched off a firestorm when he suggested that commercial space was not going to lead the way to open up the high frontier. Tyson has started a live show that he calls "Delusions of Space Enthusiasts" in which he touched on, among other things, why the Apollo program did not lead to greater things in space exploration such as going to Mars. Tyson repeats conventional wisdom about Apollo and the Cold War. In any case, it is his remarks on commercial space that has caused the most irritation.
StartsWithABang writes: Dark matter may make up 27% of the Universe's energy density, compared to just 5% of normal (atomic) matter, but in our Solar System, it's notoriously sparse. In particular, there's just a nanogram's worth per cubic kilometer, which makes the fact that we've never directly detected it seem inevitable. But recent work has demonstrated that Earth and all the planets leave a "wake" of dark matter where the density is enhanced by a billion times or more. Time to go put those dark matter detectors where they belong: in the path of these dark matter hairs.
MarkWhittington writes: Ars Technica reports that former NASA Deputy Administrator Lori Garver claimed, during a panel discussion at the Council for Foreign Relations, that many at NASA are "wary" of the Mars ambitions of SpaceX's Elon Musk. While the space agency has yielded low Earth operations to the commercial sector as part of the commercial crew program, it reserves for itself deep space exploration. Garver herself disagrees with that sentiment: "I thought, fundamentally, you just don’t understand. We’re not in a race in a swimming pool where everyone is racing against one another. We're in a cycling race where the government is riding point and the others are drafting behind us, and if someone comes alongside us and can pass us because they’ve found a better way, we don’t get out our tire pump and stick it between their spokes."
Geoffrey.landis writes: Blue Origin's "New Shepherd" suborbital vehicle made its first flight into space (defined as 100 km altitude)... and successfully landed both the capsule (by parachute) and the booster rocket (vertical landing under rocket power). This is the first time that a vehicle has made it into space and had all components fully recovered for reuse since the NASA flights of the X-15 in the 1960s. Check out the videos at various places on the web.
jones_supa writes: Turkish fighter jets shot down a Russian Sukhoi SU-24 fighter near the Syrian border on Tuesday after repeated warnings over airspace violations. Moscow said it could prove the jet had not left Syrian air space. Footage from private Turkish broadcaster Haberturk TV showed the warplane going down in flames in a woodland area. Separate footage from Turkey's Anadolu Agency showed two pilots parachuting out of the jet before it crashed. A Syrian rebel group sent a video to Reuters that appeared to show one of the pilots immobile and badly wounded on the ground and an official from the group said he was dead. This is the first time a NATO member's armed forces have downed a Russian military aircraft since the 1950s. The Guardian is following the developments with live updates. Also covered by the BBC, which notes Russian aircraft have flown hundreds of sorties over northern Syria since September. Moscow says they have targeted only "terrorists", but activists say its strikes have mainly hit Western-backed rebel groups. Turkey, a vehement opponent of Syria's president, has warned against violations of its airspace by Russian and Syrian aircraft. Last month, Ankara said Turkish F-16s had intercepted a Russian jet that crossed its border and two Turkish jets had been harassed by an unidentified Mig-29.
szczys writes: We attribute great thinking to ancient Greece. This is exemplified by the Antikythera Mechanism. Fragments of the mechanism were found in a shipwreck first discovered in 1900 and visited by researchers several times over the next century. It is believed to be a method of tracking the calendar and is the first known example of what are now common-yet-complicated engineering mechanisms like the differential gear. A few working reproductions have been produced and make it clear that whomever designed this had an advanced understanding of complex gear ratios and their ability to track the passage of time and celestial bodies. Last year research by two scientists suggested that the device might be much older than previously thought.
schwit1 writes: NASA has awarded three different companies contracts to develop advanced ion and nuclear propulsion systems for future interplanetary missions, both manned and unmanned. These are development contacts, all below $10 million. However, they all appeared structured like NASA's cargo and crew contracts for ISS, where the contractor does all of the development and design, with NASA only supplying some support and periodic payments when the contractor achieves agreed-upon milestones. Because of this, the contractors will own the engines they develop, and will be able to sell them to other customers after development, thereby increasing the competition and innovation in the field.
destinyland writes: NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s," reads the official NASA web site. But National Geographic points out that "the details haven't been announced, in large part because such a massive, long-term spending project would require the unlikely support of several successive U.S. presidents." And yet on November 4th, NASA put out a call for astronaut applications "in anticipation of returning human spaceflight launches to American soil, and in preparation for the agency's journey to Mars," and they're currently experimenting with growing food in space. And this week they not only ordered the first commercial mission to the International Space Station, but also quietly announced that they've now partnered with 22 private space companies.
Taco Cowboy writes: Washington and Beijing have established an emergency 'space hotline' to reduce the risk of accidental conflict. Several international initiatives are already in train to seal a space treaty to avoid a further build-up of weapons beyond the atmosphere. However, security experts say the initiatives have little chance of success. A joint Russia-China proposal wending its way through the UN was not acceptable to the US. An EU proposal, for a "code of conduct" in space, was having diplomatic "difficulties" but was closer to Washington's position.
