MarkWhittington writes According to a story in Medium, Dr. John Logsdon, considered the dean of space policy, addressed a meeting of the American Astronomical Society in Seattle. The author of a book on President Kennedy's decision to go to the moon and an upcoming book on President Nixon's post-Apollo space policy decisions had some good news and some bad news about NASA funding. The good news is that funding for the space agency is not likely to be slashed below its current $18 billion a year. The bad news is that it is not likely to go up much beyond that. If Logsdon is correct, static NASA funding will mean that beyond low Earth orbit human space exploration will remain an unrealistic aspiration. American astronauts will not return to the moon, not to mention go to Mars, in the foreseeable future.

BarbaraHudson writes: Many news organizations ran stories last fall extolling certain health benefits of chocolate. But it turns out the studies that the articles were based on didn't go quite so far. The CBC is running a pair of stories debunking chocolate's benefits to the average consumer: "Scientists have zeroed in on a family of fragile molecules known as cocoa flavanols. Research suggests they can relax blood vessels, improve blood flow and, as Small found in his study, even increase activity in a part of the brain involved with age related memory loss. But those flavanols largely disappear once the cocoa bean is heated, fermented and processed into chocolate. In other words, making chocolate destroys the very ingredient that is supposed to make it healthy.

That’s why Small’s memory study used a highly concentrated powder prepared exclusively for research by Mars Inc., the chocolate company, which also partially funded the study. ... There are lots of foods that contain potentially healthy flavanols, along with other bioactive compounds in complex combinations. So the question is: Would academic scientists in publicly funded institutions be so interested in the cocoa bean if the chocolate industry wasn't supporting so much of the research?"

It's been a long time since Slashdot has awarded the Beanies -- nearly 15 years, in fact. But there's no time like the present, especially since tomorrow edges on the new year, and in early 2015 we'd like to offer a Beanie once again, to recognize and honor your favorite person, people (or project; keep reading) of the past year. Rather than a fine-grained list of categories like in 2000, though, this time around we're keeping it simple: we can always complicate things later, if warranted. So, please nominate below whoever you think most deserves kudos for the last twelve months. Is it ...

• Edward Snowden, for the impact his leaks (though they began in 2013) have continued to make? (Or William Binney, for similar reasons?)
• Nobel Peace Prize winner Malala Yousafzay, who fought a difficult battle for children's right to an education?
• Telescope popularizer John Dobson, who died earlier this year at the age of 98, after bringing space a little more down to earth for many thousands of people?
• May-Britt Moser, her husband Edvard Moser, and John O'Keefe for their discoveries about how the brain navigates through the world?
• Eben Upton, whose little educational hardware project has bloomed into millions and millions of cheap, hackable Linux computers?
• How about Maryam Mirazkhani, the first woman to become a Fields medalist?
• Theo de Raadt, who stepped in with replacement project LibreSSL soon after cracks appeared in OpenSSL, and who's been helming the OpenBSD project since 1995?
• The ESA team that landed a probe on a comet, or the ISRO engineers who managed to send a probe to Mars on a shoestring budget?
• Anita Sarkeesian, for helping draw attention to undue harassment faced by women in the video game world?
• Someone relatively quiet or obscure who's nonetheless made the world better through some kind of interesting innovation or contribution?

Read on below to see how you can take part, and then nominate your favorite in the comments below.

astroengine writes Mars Exploration Rover Opportunity has been exploring the Martian surface for over a decade — that's an amazing ten years longer than the 3-month primary mission it began in January 2004. But with its great successes, inevitable age-related issues have surfaced and mission engineers are being challenged by an increasingly troubling bout of "amnesia" triggered by the rover's flash memory. "The problems started off fairly benign, but now they've become more serious — much like an illness, the symptoms were mild, but now with the progression of time things have become more serious," Mars Exploration Rover Project Manager John Callas, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., told Discovery News.

As illustrated in this article at io9.com, the conventional method considered for launching a manned craft to Mars might make less sense, even if it takes less time, than a more complicated but more efficient means akin to a method that's been already been successfully used to minimize the amount of fuel used in exploring both within and beyond the solar system. Known as the "Hohmann Transfer" method, this type of maneuver is known to be effective. But it is also quite expensive and relies very heavily on timing. Hence why a new idea is being proposed which would involve sending the spacecraft out ahead of Mars' orbital path and then waiting for Mars to come on by and scoop it up. This is what is known as "Ballistic Capture", a new technique proposed by Professor Francesco Topputo of the Polytechnic Institute of Milan and Edward Belbruno, a visiting associated researcher at Princeton University and former member of NASA's Jet Propulsion Laboratory. In their research paper, which was published in arXiv Astrophysics in late October, they outlined the benefits of this method versus traditional ones. In addition to cutting fuel costs, ballistic capture would also provide some flexibility when it comes to launch windows.

HughPickens.com writes Spaceflight has faded from American consciousness even as our performance in space has reached a new level of accomplishment. In the past decade, America has become a truly, permanently spacefaring nation. All day, every day, half a dozen men and women, including two Americans, are living and working in orbit, and have been since November 2000. Charles Fishman has a long, detailed article about life aboard the ISS in The Atlantic that is well worth the read; you are sure to learn something you didn't already know about earth's permanent outpost in space. Some excerpts:

"Life in space is so complicated that a lot of logistics have to be off-loaded to the ground if astronauts are to actually do anything substantive. Just building the schedule for the astronauts in orbit on the U.S. side of the station requires a full-time team of 50 staffers.

Almost anyone you talk with about the value of the Space Station eventually starts talking about Mars. When they do, it's clear that we don't yet have a very grown-up space program. The folks we send to space still don't have any real autonomy, because no one was imagining having to "practice" autonomy when the station was designed and built. On a trip to Mars, the distances are so great that a single voice or email exchange would involve a 30-minute round-trip. That one change, among the thousand others that going to Mars would require, would alter the whole dynamic of life in space. The astronauts would have to handle things themselves.

That could be the real value of the Space Station—to shift NASA's human exploration program from entirely Earth-controlled to more astronaut-directed, more autonomous. This is not a high priority now; it would be inconvenient, inefficient. But the station's value could be magnified greatly were NASA to develop a real ethic, and a real plan, for letting the people on the mission assume more responsibility for shaping and controlling it. If we have any greater ambitions for human exploration in space, that's as important as the technical challenges. Problems of fitness and food supply are solvable. The real question is what autonomy for space travelers would look like—and how Houston can best support it. Autonomy will not only shape the psychology and planning of the mission; it will shape the design of the spacecraft itself."

ErnieKey writes A major application of 3d printing that could revolutionize space travel would be using 3d printers to create structures on non-terrestrial bodies like the moon, other planets, and even asteroids. Researchers from NASA's Kennedy Space Center have been working to develop solutions to materials issues, and recently presented initial findings on the potential for using in-situ materials like basalt for 3D printing. Their innovative method is based on only using in-situ supplies, and not materials that need to be brought into space.

An anonymous reader writes: IEEE Spectrum reports on a study out of NASA exploring the idea that manned missions to Venus are possible if astronauts deploy and live in airships once they arrive. Since the atmospheric pressure at the surface is 92 times that of Earth, and the surface temperate is over 450 degrees C, the probes we've sent to Venus haven't lasted long. The Venera 8 probe sent back data for only 50 minutes after landing. Soviet missions in 1985 were able to get much more data — 46 hours worth — by suspending their probes from balloons. The new study refines that concept: "At 50 kilometers above its surface, Venus offers one atmosphere of pressure and only slightly lower gravity than Earth. Mars, in comparison, has a "sea level" atmospheric pressure of less than a hundredth of Earth's, and gravity just over a third Earth normal. The temperature at 50 km on Venus is around 75 C, which is a mere 17 degrees hotter than the highest temperature recorded on Earth.

The defining feature of these missions is the vehicle that will be doing the atmospheric exploring: a helium-filled, solar-powered airship. The robotic version would be 31 meters long (about half the size of the Goodyear blimp), while the crewed version would be nearly 130 meters long, or twice the size of a Boeing 747. The top of the airship would be covered with more than 1,000 square meters of solar panels, with a gondola slung underneath for instruments and, in the crewed version, a small habitat and the ascent vehicle that the astronauts would use to return to Venus's orbit, and home."

astroengine writes: A gas strongly associated with life on Earth has been detected again in the Martian atmosphere, opening a new chapter in a decade-old mystery about the on-again, off-again appearance of methane on Mars. The latest discovery comes from NASA's Curiosity rover, which in addition to analyzing rocks and soil samples, is sniffing the air at its Gale Crater landing site. A year ago, scientists reported that Curiosity had come up empty-handed after an eight-month search for methane in the atmosphere, leaving earlier detections by ground-based telescopes and Mars-orbiting spacecraft an unexplained anomaly. "We thought we had closed the book on methane. It was disappointing to a lot of people that there wasn't significant methane on Mars, but that's where we were," Curiosity scientist Christopher Webster with NASA's Jet Propulsion Laboratory in Pasadena, Calif., told Discovery News.

sciencehabit writes: After the Mars Reconnaissance Orbiter began beaming back close-up images of the Red Planet, researchers spotted peculiar features along the slopes of dunes: long, sharply defined grooves that seem to appear and disappear seasonally. They look like trails left behind by tumbling boulders, but rocks never appear in the sunken pits at the trail ends. Researchers initially took these gullies as signs of flowing liquid water, but a new model suggests they're the result of sand-surfing dry ice that breaks off from the crests of dunes and skids down slopes. This is no ordinary tumble — according to the model, the bases of the chunks are continually sublimating, resulting in a hovercraftlike motion that gouges the dune while propelling the ice down slopes.

hackingbear writes: China is conducting preliminary research on a super-heavy launch vehicle that will be used in its manned missions to the moon. Liang Xiaohong, deputy head of the China Academy of Launch Vehicle Technology, disclosed that the Long March-9 is planned to have a maximum payload of 130 tons and its first launch will take place around 2028, comparable to U.S.'s SLS Block II in terms of capability and likely beating its schedule. The China National Space Administration has started preliminary research for the Mars exploration program and is persuading the government to include the project into the country's space agenda, according to Tian Yulong, secretary-general of the administration. Separately, China's Long March series of rockets completed its 200th flight on Dec 7. It took 37 years for the Long March series to complete their first 100 flights, but only 7 years for the second 100 flights. In addition, the programclaims (link in Chinese) a success rate of 98%, on par with E.U.'s and beating U.S.'s 97% and Russia's 93% success rates.

astroengine writes The mountain that NASA's Mars rover Curiosity is exploring appears to have once been a lake, scientists said Monday. Mount Sharp, a three-mile-high mound of layered debris rising from the floor of Gale Crater, is believed to have formed billions of years ago, images posted on NASA's website ahead of conference call with reporters show. Sediments to create the mountain likely originated from the crater rim highlands and were transported toward the center of the crater in alluvial fans, deltas, and wind-blown drifts, scientists said. "During wet periods, water pooled in lakes where sediments settled out in the center of crater," NASA said. "Even during dry periods in the crater center, groundwater would have existed beneath the surface. Then, during the next wet period it would resurface to form the next lake. This alternation of lakes, rivers and deserts could have represented a long-lasting habitable environment."

Lucas123 writes While NASA's Orion spacecraft, which blasted off on a successful test flight today, may be preparing for a first-of-its-kind mission to carry astronauts to Mars and other deep-space missions, the technology inside of it is no where near leading edge. In fact, its computers and its processors are 12 years old — making them ancient in tech years. The spacecraft, according to one NASA engineer, is built to be rugged and reliable in the face of G forces, massive amounts of radiation and the other rigors of space."Compared to the [Intel] Core i5 in your laptop, it's much slower — much less powerful. It's probably not any faster than your smartphone," Matt Lemke, NASA's deputy manager for Orion's avionics, power and software team, told Computerworld. Lemke said the spacecraft was built to be rugged and reliable — not necessarily smart. That's why there are two flight computers. Orion's main computer was built by Honeywell as a flight computer originally for Boeing's 787 jet airliner. Not only was the launch itself successful, but the sensor-laden craft's splashdown was smooth ("bulls-eye," as NASA puts it), and NASA has now recovered the capsule. ABC News has some good photos, too.

PaisteUser sends word that NASA's Orion capsule successfully reached orbit this morning after a flawless launch atop a Delta IV Heavy rocket. Video of the launch is available on YouTube, and the Orion Mission blog has frequent updates as mission milestones are reached. Mission managers said the rocket and capsule performed perfectly during the initial phases of the test. "It was just a blast to see how well the rocket did," said Mark Geyer, NASA's Orion program manager. After Orion makes its first circuit around the planet, the rocket's upper stage will kick it into a second, highly eccentric orbit that loops as far as 3,600 miles from Earth. Then Orion will come screaming back into Earth's atmosphere at a speed of 20,000 mph — 80 percent of the velocity that a spacecraft returning from the moon would experience. This particular Orion is missing a lot of the components that would be needed for a crewed flight, and it won't be carrying humans. Instead, it's outfitted with more than 1,200 sensors to monitor how its communication and control systems deal with heightened radiation levels, how its heat shield handles re-entry temperatures that are expected to rise as high as 4,000 degrees Fahrenheit, and how its parachutes slow the craft down for a splashdown in the Pacific Ocean.

NASA's Orion paves way to Mars

According to NBC news, "A series of delays held up the maiden launch of NASA's Orion capsule on Thursday, adding some extra suspense to the first test of a spacecraft that's designed to take humans farther than they've ever gone — including to Mars." The much-anticipated launch, which had been scheduled for launch 7:05 a.m. Florida time, is to boost into orbit — empty — an instance of the Orion crew capsule intended to be part of a manned mission to Mars. As of shortly after 9 a.m. eastern time, troubleshooting has been in progress on the Alliance Delta 4 launch vehicle's hydrogen fill and drain valves in attempt to make the launch within today's launch window, which extends to 9:44 a.m. Besides the technical problem with those valves, the launch was delayed by wind, as well as by a boat that strayed into a restricted area. (Shades of the stray-boat delay in October for Orbital Science's ISS delivery launch.) Friday and Saturday have been designated as backup dates. Update: 12/04 15:03 GMT by T : The launch has been scrubbed.

A bit of housing insulation material, a battery, a motor and propellor, a radio receiver and transmitter, and servos to control the motor and a pair of ailerons, and you're ready to fly the Brooklyn Aerodrome way. This isn't a tiny radio-controlled paper airplane, but a big bruiser with a 1:1 power to weight ratio (which means it can climb like a bat out of hell) and enough guts to fly in reasonably windy conditions while carrying a camera -- except we'd better not mention cameras, since Brooklyn Aerodrome creations, whether kits or plans, are obviously intended tohelp you build model airplanes, not drones. Timothy ran into project proponent Breck Baldwin at a maker faire near Atlanta, surrounded by a squadron of junior pilots who may someday become astronauts on the Moon - Mars run -- or at least delivery drone controllers for Amazon.

An anonymous reader writes It's the oldest rock on Earth--and it's from Mars. A 4.4-billion-year-old martian meteorite, found in a dozen pieces in the western Sahara, has ignited a frenzy among collectors and scientists; prices have reached $10,000 a gram, and museums and universities are vying for slivers of it. It is the only known martian meteorite made of sediment, a conglomerate of pebbles and other clumps of minerals from when the planet was warm, wet, and possibly habitable. The story of the discovery of the rock and its significance is fascinating, as well as the details presented about the economics of rare space materials. Apropos, this older story about missing moon rocks.

schwit1 writes There's no easy way to say this: You're eating too much chocolate, all of you. And it's getting so out of hand that the world could be headed towards a potentially disastrous (if you love chocolate) scenario if it doesn't stop. ... Chocolate deficits, whereby farmers produce less cocoa than the world eats, are becoming the norm. Already, we are in the midst of what could be the longest streak of consecutive chocolate deficits in more than 50 years. It also looks like deficits aren't just carrying over from year-to-year—the industry expects them to grow. Last year, the world ate roughly 70,000 metric tons more cocoa than it produced. By 2020, the two chocolate-makers warn that that number could swell to 1 million metric tons, a more than 14-fold increase; by 2030, they think the deficit could reach 2 million metric tons.
