This is not F1 (or NASCAR): High-End Hybrids Race In Texas 26

Ars Technica takes an in-depth look at some of the tech side of the hybrid racing circuit, in particular the World Endurance Championship . From the article: Hybrid systems are allowed to deploy between 2MJ and 8MJ of energy during a single lap of Le Mans, augmenting the power from an internal combustion engine. Energy can be recovered from up to two motor/generator units (MGUs); usually this means recapturing kinetic energy from the front and rear wheels under braking. To balance things out, cars that recover and deploy 8MJ carry less fuel, and the flow rate at which they can feed it to the engine decreases. Audi's R18, with its mix of turbo diesel and flywheel hybrid technology, was king of the hill for several years, but the hybrid systems were much less powerful. Last year, Toyota's gasoline V8 and supercapacitor-powered TS040 was the car to beat. But 2015 is the year of the Porsche 919 Hybrid. Porsche chose lithium-ion batteries to hybridize the 919's turbocharged gasoline V4, and this year is able to capture and deploy the full 8MJ (Toyota is in the 6MJ class and Audi 4MJ). The article spends more space on Audi's approach than the others, but offers a cool glimpse at all three of these companies' niches within the field, as represented at the Texas' Lone Star Le Mans.

Vostochny Launch Building Built To the Wrong Size 85

schwit1 writes: The Russians have just discovered that their Soyuz 2 rocket does not fit in the building just finished at their new spaceport at Vostochny: "The cutting-edge facility was meant be ready for launches of Soyuz-2 rockets in December, but an unidentified space agency told the TASS news agency late Thursday that the rocket would not fit inside the assembly building where its parts are stacked and tested before launch. The building 'has been designed for a different modification of the Soyuz rocket,' the source said, according to news website Medusa, which picked up the story from TASS." The rocket had just been delivered to Vostochny for assembly, so this report, though unconfirmed at this time, fits well with current events.

Apollo-Era Photos Now Up at NASA's Flickr Account, In High-Res 91

Boing Boing reports that NASA has uploaded to its Flickr account 8400 photographs from the agency's Apollo days -- "just about every image captured by Apollo astronauts on lunar missions." The astronauts were shooting with some very nice cameras, and the results are worth seeing at 1800dpi.

F-35 Ejection Seat Fears Ground Lightweight Pilots 172

An anonymous reader writes: Writing for Defense News, Lara Seligman and Aaron Mehta report that "[c]oncerns about increased risk of injury to F-35 pilots during low-speed ejections have prompted the US military services to temporarily restrict pilots who weigh less than 136 pounds from flying the aircraft. During August tests of the ejection seat, built by Martin-Baker, testers discovered an increased risk of neck injury when a lightweight pilot is flying at slower speeds. Until the problem is fixed, the services decided to restrict pilots weighing under 136 pounds from operating the plane, Maj. Gen. Jeffrey Harrigian, F-35 integration office director, told Defense News in a Tuesday interview."

Moon Express Signs Launch Contract For Possible First Private Lunar Landing 70

MarkWhittington writes: According to a story in, Moon Express, one of the leading contestants in the Google Lunar X Prize competition, has made a giant leap toward its goal of being the first private group to land on the moon. The company has signed a contract with Rocket Lab, a new launch company based in New Zealand, for five launches of its upcoming Electron rocket. The first two launches will take place in 2017 and will be attempts to land the MX-1 lander on the lunar surface in time to win the prize by the current deadline by the end of that year.

NASA Targets Venus, Asteroids With Potential Missions 47

coondoggie writes: NASA this week picked five possible contenders for a relatively low-cost robotic mission to space. The five candidates from a batch of 27 –include Venus, near-Earth object and asteroid operations – will ultimately be whittled down to one or two that will cost approximately $500 million, not including launch vehicle or post-launch operations, NASA stated. The DAVINCI probe would "study the chemical composition of Venus' atmosphere during a 63-minute descent. It would answer scientific questions that have been considered high priorities for many years, such as whether there are volcanoes active today on the surface of Venus and how the surface interacts with the atmosphere of the planet." A longer-range spacecraft called Lucy would "perform the first reconnaissance of the Jupiter Trojan asteroids, objects thought to hold vital clues to deciphering the history of the solar system."

NASA's New Horizons Shows Pluto's Moon Charon Is a Strange, New World 94

MarkWhittington writes: NASA's New Horizons has returned a stunning series of images of Pluto, the dwarf planet that resides on the edge of the solar system, revealing a strange new world of ice mountains and glaciers of frozen nitrogen. NASA also released images of Pluto's largest moon Charon. Scientists expected a plain ball of rock pockmarked with craters, but what they saw was anything but plain and monotonous.

First of 2 Australian NBN Satellites Launched Successfully 56

New submitter aduxorth writes: Sky Muster, the first of the two satellites that will comprise Australia's NBN's Long-Term Satellite Service, has been successfully launched from Guiana Space Centre in South America. The two geostationary satellites will offer a total capacity of 135 gigabits per second, with 25/5Mbps wholesale speeds available to end users. The second satellite is expected to launch next year. Testing of this satellite will start soon and will continue until services are launched early next year.

The Case For Going To Phobos Before Going To Mars 148

MarkWhittington writes: The current NASA thinking concerning the Journey to Mars program envisions a visit to the Martian moon Phobos in the early 2030s before attempting a landing on the Martian surface in the late 2030s, as Popular Mechanics noted. The idea of a practice run that takes astronauts almost but not quite to Mars is similar to what the space agency did during the 1960s Apollo program. Apollo 8 and Apollo 10 each orbited the moon but did not land on it before the Apollo 11 mission went all the way to the lunar surface, fulfilling President John. F. Kennedy's challenge.

Mars Mission: How Hard? NASA Astronauts Weigh In 41

astroengine writes: In an interesting interview with Discovery News, retired NASA astronauts Clay Anderson (Expedition 15/16) and Steve Swanson (Expedition 39/40) discussed their views on how the US space agency should select the first Mars-bound astronauts — a mission that is slated to commence in the late 2020's. While Swanson thinks that the current NASA astronaut selection process should suffice for a long-duration foray to the Red Planet, Anderson isn't so sure, saying, "(Mars) doesn't require a jet fighter pilot. It doesn't require a Ph.D. astronaut — although those people would be just fine, but I think that it's going to take people that are very good generalists, that can do many things." As depicted in the upcoming Matt Damon movie, "The Martian," Mark Watney (Damon) is thrown into an unexpected, life-threatening situation, requiring him to use his general skill set to survive on the barren landscape until he's rescued. As the first manned missions to Mars will likely throw unforeseen challenges at the explorers, it will probably be a good idea to have a crew that are adept at thinking on the fly and skilled in many different areas rather than being a specialist in one.

Talking Science and God With the Pope's New Chief Astronomer 268

sciencehabit writes: On 18 September, Pope Francis appointed Jesuit brother Guy Consolmagno as the new director of the Vatican Observatory, which employs a dozen astronomers to study asteroids, meteorites, extrasolar planets, stellar evolution, and cosmology. The observatory is based at the pope's summer residence south of Rome and operates a 1.8-meter telescope in Arizona, where the skies are clearer. Science Magazine chatted with Consolmagno about a variety of topics, including whether God gets in the way of doing good astronomy. Consolmagno said, "First of all, I want to provide space for other astronomers to do their work. And I also want to show the world that religion supports astronomy. It is often religious people who most need to see that; they need to know that astronomy is wonderful and that they shouldn't be afraid of it. I often quote John Paul II, when he said [of evolution] that "truth cannot contradict truth." If you think you already know everything about the world, you are not a good scientist, and if you think you know all there is to know about God, then your religious faith is at fault."

Are Enterprise Architects the "Miltons" of Their Organizations? 131

StewBeans writes: InfoWorld recently pointed out that the "architect" part of enterprise architect is a misnomer, because what they are building can't be a static, unmoving structure or it will fail. Businesses need to remain fluid and flexible as technology and consumer behaviors evolve, so modern enterprise architects must "develop frameworks with constant change as a first principle." The business value of these frameworks, however, is often called into question, and EAs have even been called the "Miltons" (as in Milton from Office Space) of the enterprise. If the field of enterprise architecture is changing to focus more on digital transformation, how does that compete with or compliment IT's role in the enterprise, which is also focused on digital transformation? The enterprise architect of BJ's Wholesale breaks down his responsibilities and addresses some myths about the EA role in this article.

Rosetta's Comet Is Actually 2 Comets Stuck Together 45

astroengine writes: Scientists have solved the mystery of why the comet being studied by Europe's Rosetta spacecraft is shaped like a rubber duck — it started off as TWO separate comets, a new study shows. Ever since Rosetta sent back pictures of its twin-lobed target more than a year ago, scientists have debated whether the comet, known as 67P/Churyumov-Garasimenko, could be the result of two comets that merged together during the solar system's early years. The other option is that the so-called "neck region" between 67P's two lobes experienced some particularly active and still unexplained outgassing over the eons, eroding its more spherical shape into a body that resembles a rubber duck. "Our study rules out the possibility that the comet shape is the outcome of erosion," planetary scientist Matteo Massironi, with the University of Padova in Italy, wrote in an email to Discovery News. Rather, the neck region is where two independent bodies collided, analysis of high-resolution images taken by the orbiting Rosetta spacecraft shows.

Scientists Have Spotted the Signs of Flowing Water On Mars 260

New submitter universe520 writes: Using neat imaging technology that allows them to determine the chemical compound of a substance by looking at the light reflected from it, scientists have spotted the traces of flowing water on Mars. By looking at the dark streaks on some photos of Mars, Lujendra Ojha from Georgia Tech has found compounds that are made in liquid water—meaning that water may be trickling down those streaks when the climate is just right. From the linked Economist piece: Details remain to be worked out, including where the water in question originates. Possibly, it derives from subsurface ice. Or it might condense out of Mars’s thin, dry atmosphere. Wherever it does come from, though, the amounts in question are modest in the extreme. But even modest amounts of water are intriguing to biologists. If Martians evolved during their planet’s earlier, wetter phase, the continued presence of water means it is just about possible that a few especially hardy types have survived until the present day—clinging on in dwindling pockets of dampness in the way that some “extremophile” bacteria on Earth are able to live in cold, salty and arid environments.

ISRO Launches Astrosat, India's First Dedicated Space Observatory 40

vasanth writes with a link to the Hindu, which reports: A few days after it celebrated the successful completion of a year around the Red planet by its first inter-planetary mission — the Mars Orbiter, the Indian Space Research Organisation (ISRO) on Monday launched its first dedicated multi wavelength space observatory into space, besides six satellites for Canada, Indonesia and the United States. Though the national space agency has launched satellites for Indonesia and Canada earlier, this is the first time ISRO is launching satellites for the United States. ASTROSAT's sensors will provide coverage in optical, Ultraviolet, low and high energy X-ray ranges, rather than the concentrating on a narrower range. Major institutions all over India will take part in the new craft's observations.

Tonight's Dazzling 'Supermoon' Lunar Eclipse: What You'll See 95

An anonymous reader writes: Astronomers are gearing up to spot a rare phenomenon, as a lunar eclipse coincides with a so-called "supermoon". Whether you think it marks the beginning of the apocalypse or is just a neat thing to look at tonight, Live Science has some tips and a timetable for best viewing in your area. The moon enters Earth's full shadow, called the umbra, starting at 9:07 p.m. EDT (6:07 p.m. PDT). The total eclipse begins at 10:11 p.m. EDT (7:11 p.m. PDT). Totality lasts an hour and 12 minutes, at which point a bright sliver of the moon will emerge and grow.

How Can NASA's Road To Mars Be Made More Affordable? 211

MarkWhittington writes: The Houston Chronicle's Eric Berger published a piece that touched on one of the most vexing issues surrounding NASA's "road to Mars," that being that of cost. How does one design a deep space exploration program that "the nation can afford," to coin a phrase uttered by the old NASA hand interviewed for the article? The phrase is somewhat misleading since one of the truisms of federal budgeting is that the nation can afford quite a bit. A more accurate phrase might be, "that the nation is willing to spend."

How To Clean the Cruft Left By a Windows 10 Upgrade 204

MojoKid writes: Microsoft may have given you a free Windows 10 upgrade but it's not without some left over file clutter that some folks don't realize is left on a system after migration. It's not rocket science but there are a few key strategies to tidy up the file bloat an OS migration can sometimes leave behind and to further optimize an upgraded Windows 10 installation. The ability to roll back to your Windows 7 or 8.1 installation within 30 days is a very easily overlooked feature of the Windows 10 upgrade process. The feature is a lifesaver if you encounter issues, such as missing or incompatible drivers, and need to quickly recover without starting from scratch. This ability doesn't come without consequences, though. In order to offer this feature, Windows 10 is essentially keeping another completely separate Windows installation on your PC. This will need to go, once you've determined that you are sticking with Windows 10 and everything seems happy enough. These files are scattered throughout your system and include a number of hidden directories, with the bulk of them located in Windows.old and the hidden $Windows.~BT and $Windows.~WS directories.

Why NASA's Road To Mars Plan Proves That It Should Return To the Moon First 194

MarkWhittington writes: published the results of current NASA thinking concerning what needs to be launched and when to support a crewed mission to Phobos and two crewed missions to the Martian surface between 2033 and 2043. The result is a mind-numbingly complex operation involving dozens of launches to cis-lunar space and Mars using the heavy lift Space Launch System. The architecture includes a collection of habitation modules, Mars landers, propulsion units (both chemical rockets and solar electric propulsion) and other parts of a Mars ship.

Making Mining the Asteroids and the Moon Legal 162

MarkWhittington writes: Popular Science reported on a bill called the Space Act of 2015 that has passed the House and may soon pass the Senate that will allow private companies to own the natural resources that they mine in space. The idea would seem to be a no-brainer. However, the bill is causing some heartburn among some space law experts, especially in other countries. Fabio Tronchetti, a lawyer at the Harbin Institute of Technology in China, argues that the law would violate the Outer Space Treaty.
