The Economist: The World in 2010

goodnewsfortheinsane — Sat, 14 Nov 2009 17:09:43 -0800

In 2010, Obama will have a miserable year, NATO may lose in Afghanistan, the UK gets a regime change, China needs to chill, India's factories will overtake its farms, Europe risks becoming an irrelevant museum, the stimulus will need an exit strategy, the G20 will see a challenge from the "G2", African football will unite Korea, conflict over natural resources will grow, Sarkozy will be unloved and unrivalled, the kids will come together to solve the world's problems (because their elders are unable), technology will grow ever more ubiquitous, we'll all charge our phones via USB, MBAs will be uncool, the Space Shuttle will be put to rest, and Somalia will be the worst country in the world. And so the Tens begin.

The Leonid Meteor Shower 2009

nickyskye — Sat, 14 Nov 2009 16:34:18 -0800

NASA's Fluxtimator helps calculate the meteor shower activity in your area. There will be one of the biggest meteor shower events of our lifetime, the Leonid Meteor shower of 2009. Start time: this Monday November 16, 2009 at 11:00pm EST. End Time: Tuesday, November 17, 2009 at 4:00am EST (best 2am to 4 am EST). An Atomic Age song in mp3 to celebrate: What Is A Shooting Star. What Is A Shooting Star, written by Hy Zaret and Lou Singer and originally recorded by Tom Glazer for the 1959 album Space Songs. National Geographic says, "you may see anywhere from 30 to 300 shooting stars an hour, depending.." NASA and Caltech say up to 500 an hour. Quoting Orin K, a friendly, generously informative astronomy geek on FaceBook: "If you can see stars directly over head, you will see the brighter meteors only. It's best to get out of town or go to a larger park with trees If you are interested in finding a USA or Canada dark sky site near you, check out this site:http://cleardarksky.com/csk/ and an interesting Calif example observing spot off Rte 40- http://cleardarksky.com/c/AmbyCtCAkey.html?1 Find this on google maps with satellite and terrain views. Use the light pollution map choice to find dark areas near you. Use the sites by state or miles, mouse over pins for site name, dbl click to find next 48 hr forecast of seeing conditions. Black and blue pins are darker sites. Makes Maps, etc. Also, google and install - Cartes du Ciel - free software. Also, well before you leave, check out ( when it is working! ) - the GOES 12 live view satellite 6 hr visible and infrared 6 hr animation to see the cloud flow patterns in your area of interest: http://wwwghcc.msfc.nasa.gov/GOES/goeseastconus.html Get advice from local astronomy clubs. Take Lawn Chairs or thick foam pads, sleeping bags, layered clothing, wool caps, hand warmers, warm drinks. camera, 24mm lens at f2.8 with 20 second or more exposure, on tripod, and shutter cable trigger or 10 second count down shutter release. No binoculars or telescopes needed - just look up. The head stars of Constellation Leo will be rising after the Gemini Twins and the planet Mars in the northeast after midnight. Record brightness and direction of travel. Do clear nights Nov 16-19, but 11PM to dawn on 17 into 18 is best. Also think badly of ground fog, local light domes from cities, farmyard lights. As Ever, Orin, near Chicago." What do the colors under the "light pollution" column mean? Viewing suggestions in California l on the East Coast.

"Terraforming would be to create an uncontained planetary biosphere emulating all the functions of the biosphere of the Earth" M.J. Fogg

NASA scientists claim to have found significant amounts of water, after successfully bombing the moon last month. This may have implications on possible Terraforming efforts as well as NASA's goal to understand the nature and distribution of habitable environments in the Universe. What might it look like?

On October 9th, NASA spacecraft will run into the moon, and on purpose. The Lunar Crater Observation and Sensing Satellite (LCROSS) and its rocket's Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the Lunar Reconnaissance Orbiter (LRO). The initial impact site was the crater Cabeus A, but the target was later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided guides for amateur observations of the impact, a facebook group, and a Twitter feed so you don't miss the moment.

José Hernández was a migrant worker when he first started to dream about becoming an astronaut. He is the first astronaut to Twitter in Spanish from space on shuttle mission STS-128. NASA wasn't happy about the controversy he caused when he advocated for the legalization of undocumented immigrants. He is not the first Hispanic-American to fly on the space shuttle. Hernández is a national hero in Mexico and has been invited to dine with President Calderon.

Making Space Omelettes

Marisa Stole the Precious Thing — Sat, 12 Sep 2009 10:59:33 -0800

Last Tuesday, The Augstine Commission - an independent council created earlier this year to study NASA's human spaceflight objectives - released their findings. While many are responding to the report's grim findings on NASA's budget woes, former aerospace engineer Rand Simberg has a criticism of his own: "If our attitude toward the space frontier is that we must strive to never, ever lose anyone, it will remain closed. If our ancestors who opened the west, or who came from Europe, had such an attitude, we would still be over there, and there would have been no California space industry to get us to the moon forty years ago. It has never been 'safe' to open a frontier, and this frontier is the harshest one that we've ever faced."

Galileo would be so proud.

In the next few weeks, NASA will present President Obama with options for the near-term future of human spaceflight. A manned flight to Mars is one possibility. But if we do send astronauts to Mars, do we really need to bring them home again?

Orbital Skydiving

Orbital skydives to follow inflatable heatshield success? "NASA has announced a successful live test of a prototype inflatable heat shield for re-entry to a planet's atmosphere. The blow-up shield could have important implications for future missions to Mars - and also, perhaps, for the nascent field of orbital spacesuit skydiving."

In 2004, the Stardust mission passed through the tail of comet 81P/Wild (aka Wild 2); in 2006, that captured comet dust was returned to Earth. Now, researchers have found glycine, one of the amino acids in proteins, in that cometary material. The glycine found is definitely extraterrestrial in origin, since the isotope of carbon that it's built from isn't found in any great quantity on Earth. Previously:

Neil Armstrong: One Badass Mother Fucker.

cmchap — Wed, 05 Aug 2009 14:22:07 -0800

Neil Armstrong was a test pilot before he was an astronaut. He had his pilot's license before he had his driver's license. But even he had some trouble getting used to that darned Lunar Excursion Module (LEM). While testing the Lunar Landing Research Vehicle (LLRV), Neil Armstrong was a second and a half from death, and just walked away. Actually, the guy in that video isn't Neil. That was Deke Slayton, because apparently NASA didn't care if he got maimed while testing the first prototype. No. The Neil Armstrong crashes better, faster, and with MORE FIRE! (Reenactment in "From the Earth To the Moon) Fear not, though, for Neil safely landed the LLRV a few weeks later for the media. Upon liftoff of Apollo 11, Neil Armstrong was a little surprised. When it came time to land on the Moon, just over a year after crashing the LLRV, The LEM's guidance system started giving unforeseen errors. Armstrong ignored the errors, realized that they'd overshot their target landing spot, took matters into his own hands, and found a better, non-bouldered area on which to land. With 24 seconds of fuel left, he landed the Eagle on the surface of the moon so softly that the shock absorbers didn't compress (#6), making his one small step a much larger step than anticipated.

Circling the lonely moon by yourself, the loneliest person in the universe, weren't you lonely?

Astronaut Michael Collins – "I really believe that if the political leaders of the world could see their planet from a distance of 100,000 miles their outlook could be fundamentally changed. That all-important border would be invisible, that noisy argument silenced. The tiny globe would continue to turn, serenely ignoring its subdivisions, presenting a unified façade that would cry out for unified understanding, for homogeneous treatment. The earth must become as it appears: blue and white, not capitalist or Communist; blue and white, not rich or poor; blue and white, not envious or envied."

The Lunar Orbiter's Kodak moment

prinado — Fri, 17 Jul 2009 16:16:01 -0800

NASA's Lunar Reconnaissance Orbiter has returned its first images of the Apollo moon landing sites. The spacecraft’s onboard camera photographed Lunar Module descent stages at five of the six Apollo sites—11, 14, 15, 16, and 17. The Apollo 12 site will be photographed in coming weeks. The Apollo 14 image is particularly interesting: ideal lighting conditions resolve additional details, including the Apollo Lunar Surface Experiment Package and the tracks left by the astronauts’ footprints and/or the Modularized Equipment Transporter, a 2-wheeled, rickshaw type cart for carrying around tools, cameras and sample cases on the lunar surface. These first images were captured before the spacecraft reached its final mapping orbit—future images of the Apollo sites will have two to three times greater resolution.

Open Rotor: Jet Engine with a Mohawk

...possums — Thu, 09 Jul 2009 13:18:37 -0800

Ultra-High Bypass (UHB) or "propfan" jet engines received attention in the late eighties as an economical and greener alternative to currrent GTF and ATF jet technologies. Adoption was partially prevented by industry fears that the external propellers would being seen as a step backwards. Evidently, General Electric and NASA are reinvesting in the technology.

Moon Landing Tapes Found! All the videos you've seen of the first moon landing are crap. Remember, back in the day, video cameras and recorders were two different things. So it went like this: camera on moon sends footage to Australia, where it's recorded on tape (and then those tapes were lost), then downsized onto a smaller monitor, which is filmed by another video camera, uploaded to satellite, and disseminated around the world. America watches it on TV, cheers. Some of this footage is filmed off of a television onto 16mm film. This is what goes into the national archives. Crap. So, the original tapes have been found (spoiler: they never left Australia). So what, right? How good could they be, recorded back in the late 60's and all? Pretty darn good, apparently...seems recording heads were much better than the output available at the time (like playing a Blu-Ray disc on a B&W TV), and several recent projects have shown that it's possible to extract very high resolution data from these old analog tapes. How hi-rez? High enough to see Neil Armstrong's nipples get hard. (be sure to click on that picture) So when can we see this amazing footage? Probably soon.
