Space elevator just broke? Wondering what's going to happen? Wonder no more!
A perfect space storm, which happens about every century, like the one that occurred in 1859, could cause "catastrophic social and economic disruptions", according to a new study by the National Academy of Sciences on behalf of NASA. "Potable water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; immediate or eventual loss of heating/air conditioning, sewage disposal, phone service, transportation, fuel resupply and so on," the report states. Outages could take months to fix, the researchers say. Banks might close, and trade with other countries might halt. The next peak in solar activity is expected around 2012.
NASA releases the Columbia shuttle disaster report. Space shuttle Columbia broke up during re-entry in 2003 as a result of damage sustained to its thermal protection system. This report details the possible lethal incidents and the investigation board's recommendations based on their findings. [more inside]
Where did Venus’s water go? Water may have once been as abundant on Venus as it is on Earth. New data from the Venus Express suggests that the planet's lack of a magnetic field has allowed water in the atmosphere to be stripped apart and carried into space by the solar wind.
Rethinking Earthrise. On the 40th anniversary of the NASA's Apollo 8 mission [caution: weird JFK animation], which answered Stewart Brand's epochal, LSD-inspired question "Why haven't we seen a photograph of the whole Earth yet?" with an unforgettable image of a seemingly fragile and isolated blue planet, Nature editor Oliver Morton -- author of a new book on photosynthesis called Eating the Sun -- disputes the notion that the Earth is fragile and isolated. "The fragility is an illusion," he writes. "The planet Earth is a remarkably robust thing, and this strength flows from its ancient and intimate connection to the cosmos beyond. To see the photo this way does not undermine its environmental relevance -- but it does recast it."
Martian maps and a few others in good quality PDF.
Video and audio from a camera mounted on one of the side solid rocket boosters during the launch of STS-124. As the camera is initially facing the main booster, there's not that much to see (except water vapor collecting on the lens and interesting-looking changes in the main booster's surface) until around 1:50, when the booster rocket is jettisoned. After that, enjoy the ride from space to splashdown, but watch out for flying debris! Here's the view from the other booster, without sound. More onboard STS cameras, previously. [N.B. -- Adjust volume accordingly, it gets loud! Looks even better in high-quality and full-screen modes.]

Source Of Geysers On Saturn's Moon Enceladus May Be Underground Water. Earlier this year the Cassini spacecraft detected organic material in the geysers of Enceladus. The question now is, how's the fishing?
The Little Fox has gas. Giovanna Tinetti using the Hubble Telescope says (in Nature - subscription required) there's Carbon Dioxide in the atmosphere of the Jupiter sized, hot, extrasolar planet HD 189733b. Scientists have also found methane clouds in its atmosphere, as well as water vapor. Tinetti (who looks a bit like Kari Byron from mythbusters if you squint) also found evidence of methane.
Fire in the sky - a meteor burns up somewhere over Western Canada. Really impressive video here, another video, TV news with more footage here.
At a cost of $20,000 a pound (google search prices vary). You have to wonder how much this cost. Poor Heide Stefanyshyn-Piper dropped her tool bag But don't worry, NASA tracks NEOs. And then there is the missing spider. Lastly, throwing in a gratuitous link to APOD (because it's cool and I can't wait to see the tool bag show up).
An election of a new President brings forth new ideas on the Vision for Space Exploration. The Planetary Society is lobbying to remove the Moon from the equation, which prompted Apollo astronaut, ex-senator, and geologist Harrison Schmitt to resign from the board in protest. Meanwhile moon-free plans proliferate. What will Obama do? Interesting hints are given in a position paper written by people associated with his transition team. [more inside]
Magnetic Portals Connect Sun and Earth. "Like giant, cosmic chutes between the Earth and sun, magnetic portals open up every eight minutes or so to connect our planet with its host star. Once the portals open, loads of high-energy particles can travel the 93 million miles (150 million km) through the conduit during its brief opening, space scientists say." [Via]
Former Redskins linebacker Ken Harvey wants to bring sports to space. He calls it Space Sportilization
From grainy stills to gorgeous high-resolution portraits, from intimate pairings to stark contrasts, and from old standbys to little-known surprises, The Planetary Society's Earth galleries offer a rich collection of stunning photography and video footage of our world as seen from both planetary spacecraft and geostationary satellites. It is a vista that has inspired many a deep thought in the lucky few that have seen it firsthand [previously]. Oh, and the rest of the Solar System is pretty neat, too.

SpaceX's fourth flight was successful. Scaled Composites' X-Prize winning SpaceShipOne made the first privately funded hop into space. SpaceX just took the next big step and inserted a dummy payload into orbit. Next, they will launch the much larger Falcon 9 and later test out the human-carrying Dragon. CEO Elon Musk also enjoys dabbling in banking and exotic electric cars.
Japan is showing renewed interest as another contender in the race to build the world's first space elevator. Japanese scientists believe they can complete the project with an optimistic trillion yen budget, and are sponsoring an international conference (no English) this November to draw up a timetable.

Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]
The Autonomous NanoTechnology Swarm (ANTS) "...is a generic mission architecture consisting of miniaturized, autonomous, self-similar, reconfigurable, addressable components forming structures. The components/structures have wide spatial distribution and multi-level organization. This ‘swarm’ behavior is inspired by the success of social insect colonies...." ANTS may one day teem through the solar system.... (last two links large QT files) [more inside]
Is life possible even in the coldest depths of space? If so, this tough little guy has long been thought to be a good candidate. Now, finally, analysis of the Tardigrades (a.k.a. "water bears") exposed to open space as part of the TARDIS project is finally complete. So what's the verdict? [more inside]
Science Hack is a unique search engine for science videos focusing on Physics, Chemistry, and Space. For example, things to do with sulfur hexafluoride. Still growing, the editors are presently indexing other scientific fields of study including Geology, Psychology, Robotics and Computers. Ever wonder why things go bang?
Lost with yesterday's third failure of Space Exploration Technologies' Falcon 1 rocket were the ashes of actor James "Scotty" Doohan, who, along with astronaut Gordon Cooper and over two hundred other cremains, attempted to reach orbit not once, but twice.
"We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month, but this is the first time Martian water has been touched and tasted."
The gyrojet pistol (video) - a handgun firing 13mm rocket ammunition, was an attempt to revolutionise gun design in the 1960s. Around a thousand were produced, and some may have seen use in Vietnam. Rifle and carbine versions were also produced. Design problems meant that it never seriously competed conventional firearms, but there is a modern attempt to revive the concept.
Brewster Khale over at Internet Archive just announced they are working with NASA to make available the most comprehensive compilation ever of NASA's vast collection of photographs, historic film and video at nasaimages.org. It combines for the first time 21 major NASA imagery collections into a single, searchable online resource.
The European Space Agency's Mars Express Probe has sent back some beautiful new high-resolution images of the Echus Chasma. More images and information can be found here.
An Interactive Space Simulator "Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole. You can simulate and interact with our solar system: the 8 planets,160+ moons, and hundereds of asteroids, the nearest 1000 stars to our Sun, and our local group of galaxies."

How space toilets work. They've come a long way. They sure don't look like the one in my house. What happens when they break? NPR explains the logistics of the repair process. Oh thank heavens, it's working again.
With all the crystal skulls, nazca lines and such at the box office these days now might be the ideal time to reacquaint yourself with the theories of Erich von Däniken. What better way to do it than by watching William Shatners Mysteries of the Gods ( Pt. 1, Pt. 2, Pt. 3, Pt. 4, Pt. 5, Pt. 6, Pt. 7, Pt. 8, Pt. 9, Pt. 10)(MULTI LINK YOUTUBE SHATNERFEST)
Do Our Brains Change When We Travel in Outer Space? A book of compiled accounts of astronauts and cosmonauts called The Overview Effect puts forth anecdotal evidence towards that end. The Overview Institute declares it as fact and aims to induce the change in as many people as possible. One space tourist has volunteered to be a human guinea pig in 2009.
The Atlantic has an interesting article about the high probability of "space rocks" hitting the earth, possibly as high as a 1 in 10 chance of a major catastrophe each century. Not a new theme, but the article has some new developments suggesting it is more common than once thought. Includes a 10 minute video.
Before developing exotic space propulsion systems like the ion engines on deep space probes, he developed guidance systems for Nazi Germany's ballistic missile, the V2. As Dr. Werner von Braun's Chief Scientist, he was one of the brilliant minds that founded the Marshall Space Flight Center in Huntsville, Alabama and sent astronauts to the moon atop MSFC's Saturn V rocket. Dr. Ernst Stuhlinger, one of the last surviving rocket scientists extracted from Nazi Germany in Operation Paperclip, died today at 94.

The "Great Filter" is a hypothetical barrier to explain why civilisations are so unlikely to progress to the point of inter-stellar colonisation that we have not encountered any in 40 years of looking. Maybe humanity has already negotiated the filter - as some massive evolutionary improbability - or perhaps it lies in our future as an almost-certain threat to our existence? We should hold our breath as we look for evidence of life on Mars.
" It looks as if our Milky Way will be subsumed into its giant neighbour, the Andromeda galaxy...." A (not so) little trove of images of galactic collisions has been released to mark the 18th anniversary of the Hubble telescope's launch. Gravitic Mayhem. (via)
