eldavojohn writes "After Huygens & Cassini corrected our assumptions about Titan (a moon of Saturn), scientists are now debating about their next mission, and one of the choices is the Titan and Saturn System Mission. What makes Titan a good choice? 'Although the atmosphere of Titan is filled with a smoggy orange hydrocarbon haze, it is primarily composed of nitrogen — just like Earth's. In fact, Astrobiologists think Titan's atmosphere may be quite similar to how the Earth's was billions of years ago, before life on our planet generated oxygen.' We also discussed its liquid hydrocarbons earlier this year."

bmcage writes "The ESA unveiled the Intermediate eXperimental Vehicle, a real re-entry vehicle. Although it will not be reused, it has a better geometry than NASA's Orion or the Russian Soyuz, giving better lift, and control. This is not done by the addition of useless wings, but by using two brakes. Finally a departure from the Apollo design that is actually better?"

DeviceGuru writes "Astrobotic Technology has unveiled plans for a series of robotic expeditions to the Moon. The lunar rovers will explore high-interest areas of the Moon's surface and beam the data back to the Earth. The plan is to accumulate an extensive library of lunar data and sell it to governments and private corporations (PDF), much as Navteq's data forms the backbone of most terrestrial GPS services. Astrobotic's first goal is to win Google's $30 million Lunar X Prize, with a May, 2010 trip to the Apollo 11 landing site at Mare Tranquillitatis."

Kligat writes "Scientists have found two asteroid belts around the star Epsilon Eridani, the ninth closest star to our solar system. Epsilon Eridani also possesses an icy outer ring similar in composition to our Kuiper Belt, but with 100 times more material, and a Jovian mass planet near the edge of the innermost belt. Researchers believe that two other planets must orbit the 850 million year old star near the other two belts. Terrestrial planets are possible, but not yet indicated."

Andrew Moseman writes "Part of the trouble NASA is encountering while fixing the Hubble Space Telescope comes from the fact that it's been up there for nearly two decades, and therefore carries computer systems long outdated here on Earth. 'One of the main computers that the Goddard team has been struggling with during the repair attempts runs on an Intel 486 chip, the height of 1989 technology.' Many of NASA's long-running missions rely on antiquated systems — the Voyager probes each have about 32k of memory — but the scientists say they can manage."

Toren Altair writes "Soyuz TMA-13 with ISS Expedition Crew 18 and Richard Garriott successfully launched from Baikonur Cosmodrome at 7:01 UT (3:01 EDT). The Soyuz capsule will dock to the ISS in two days. Garriott will return to Earth with Expedition 17 crew members, Commander Sergei Volkov and Flight Engineer Oleg Kononenko on October 23." With the extra attention on this launch, the Russians have gone out of their way to say that the return of the Soyuz vehicle will be safe, after a couple of different malfunctions in the past year. Garriott is in space partly for recreation, and partly as a promotion for his latest MMO, Tabula Rasa. He took with him a hard drive filled with information about humanity, as well as DNA sequences from Tabula Rasa players and various celebrities (including Stephen Colbert and Stephen Hawking) to 'preserve' that data in case of a disaster on Earth. Garriott will also spend time running and participating in experiments. Coverage of the Soyuz mission is ongoing at NASATV.

As_I_Please writes "At 8:40AM (GMT) this morning, Chinese astronaut Zhai Zhigang successfully spent 18 minutes in a tethered spacewalk outside the spacecraft Shenzhou 7. This is an important step in China's goal of building an orbiting space station and sending astronauts to the moon."

DynaSoar writes "NASA astrophysicists have discovered what they claim is something outside the observable universe exerting an effect on the observable. The material is pulling clusters of galaxies towards a region of space known not to contain sufficient matter to create the effect. They can only speculate on what the material is and how space might differ there: 'In these regions, space-time might be very different, and likely doesn't contain stars and galaxies (which only formed because of the particular density pattern of mass in our bubble). It could include giant, massive structures much larger than anything in our own observable universe. These structures are what researchers suspect are tugging on the galaxy clusters, causing the dark flow.'"

hackingbear writes "According to a report by Hong Kong newspaper Mingpao Daily (poor Google translation), quoting the Director of Jiuquan Launch Center, China is set to build a space station by snapping together four spaceships (Shenzhou 7, 8, 9, and 10), to be launched sequentially. Though other reports indicates that taikonauts abroad SZ 7 will return to Earth on September 28, the official said the ship will remain in the orbit to be docked with unmanned Shenzhou 8 and 9. Finally, the manned spaceship Shenzhou 10 will be launched and dock with the other three, completing the space station." A story at Space.com also briefly mentions Shenzhous 8 and 9 (with no mention of number 10), and adds that China has selected its first spacewalker.

jerryasher writes "In a leaked memo, NASA Administrator Mike Griffin discusses 'the jihad' to prematurely terminate the Shuttle and what that means for the International Space Station. One implication: there may come a long interval when only our Russian Allies are aboard the Space Station. Add that bit of irony to your new cold war kit and then wonder why Griffin discusses why we wouldn't sabotage the Space Station, and how and why the memo got leaked in the first place."

Adam Korbitz writes "Astrobiology Magazine reports on new research indicating extremophile microbes may be able to live on Titan, the sixth and largest moon of Saturn — in spite of the fact that the moon is largely ice and covered with lakes of liquid methane. Titan joins Mars, Venus, Europa and Enceladus as a potential home to extremophile life in our solar system."

eonlabs writes "A new paper has been published on the formation of stars in close proximity to a supermassive black hole. Their formation has not been well understood until now, but with the help of a year of supercomputer time, scientists have been able to model the interstellar processes needed to produce them. The results not only match up well with earlier observations, but provide clues as to how their formation is remotely possible. It also helps clear up previous research in this area. 'The simulations...followed the evolution of two separate giant gas clouds up to 100,000 times the mass of the Sun, as they fell towards the supermassive black hole. ...The disrupted clouds form into spiral patterns as they orbit the black hole... In these conditions, only high mass stars are able to form and these stars inherit the eccentric orbits from the elliptical disc.'" The paper itself was published in Science, but you'll need a subscription to read more than the abstract.

leetrout writes "Fox News has the story on a parachute test failing on a mock up of the new Orion spacecraft. 'This is the most complicated parachute test NASA has run since the '60s,' said Carol Evans, test manager for the parachute system at NASA's Johnson Space Center in Houston. 'We are taking a close look at what caused the set-up chutes to malfunction. A failure of set-up parachutes is actually one of the most common occurrences in this sort of test.' Space.com has the video."

TnGoastiiaiu submitted a space.com story that expands on coverage we've had earlier about improvements being made to the ISS to increase crew capacity. He writes "ISS gets new recycling gear that transforms human waste to drinking water. Some of the water will be used to get Oxygene, too. This way it will soon be possible to host more crew members. " Also, someone needs to smack the webmaster over there for putting a background texture behind the text. It's pretty unreadable along the left hand side of the screen.

Hugh Pickens writes "A new study at the Jet Propulsion Labs shows that weak gravitational pull of a "gravity tractor" could deflect an Earth-threatening asteroid if it was deployed when the asteroid was at least one orbit away from potential impact with Earth. First a spacecraft would be crashed directly into the asteroid, similar to the Deep Impact mission that impacted a comet in 2005. This would provide a big change of direction, but in a less controllable fashion that could push the path of the asteroid into a dangerous keyhole. But then a second spacecraft, the gravity tractor, would come into play, hovering about 150 meters away from the asteroid, to exert a gentle gravitational force, changing the asteroid's velocity by only 0.22 microns per second each day. Over a long enough time, that could steer it away from the keyhole. In the simulation, a simple control system kept the spacecraft in position, and a transponder on the asteroid helped monitor its position and thus determine its trajectory more precisely than would be possible otherwise. 'The gravity tractor is a wimp, but it's a precise wimp,' said astronaut Jack Schweickart. 'It can make very small, precise changes in orbit, and that's what you need to avoid a keyhole.'"

A year ago we took note when Brian May, guitarist for Queen for the last 30 years, submitted his thesis for a Ph.D. in astrophysics. The news now is that the thesis has been published. You, too, can read all about the population of tiny asteroids and space dust that cause the Zodiacal light. The completed thesis appears as the book "A Survey of Radial Velocities in the Zodiacal Dust Cloud" (Springer and Canopus Publishing Ltd., 2008), available at Amazon for $71.96. May was awarded his Ph.D. last summer and accepted a position as chancellor at a British university in November.

Gibson writes "A team of 57 engineers at NASA's Marshall Spaceflight center feel that the Ares rocket is not the best solution for launching the new CEV. They are currently working on their own time developing an alternative launch system known as Jupiter. The 131 page proposal, along with other information, is available on the project website. Proponents of the project say that it is 'simpler, safer, and sooner' than the Ares project, predicting the ability for a return to the moon in 2017, two years before the current goal. Ares management has so far dismissed the proposal as a 'napkin drawing.'"

onehitwonder writes "Astronomers have discovered that the Earth emits awful, ear-piercing chirps and whistles that could be heard by any aliens who might be listening, according to an article up at Space.com. The sounds are created by charged particles from the solar wind colliding with Earth's magnetic field. This article explains more about the sounds and links to an audio recording of it."

swestcott brings us a story from Space.com about the possibility of finding evidence for ancient Earth life on the moon. A team of scientists has published work confirming that meteorites originating from Earth could have remained sufficiently intact while colliding with the moon to allow the survival of biological evidence for life. Quoting: "Crawford and Baldwin's group simulated their meteors as cubes, and calculated pressures at 500 points on the surface of the cube as it impacted the lunar surface at a wide range of impact angles and velocities. In the most extreme case they tested (vertical impact at a speed of some 11,180 mph, or 5 kilometers per second), Crawford reports that 'some portions' of the simulated meteorite would have melted, but 'the bulk of the projectile, and especially the trailing half, was subjected to much lower pressures.'"

Kligat writes "The International Astronomical Union has decided that Pluto and Eris should be classified as "plutoids," alongside their 2006 classification as dwarf planets. Under the definition, the self-gravity of a plutoid is enough for it to achieve a near-spherical shape, but not enough for it to clear its orbit of its rocky neighbors, and the plutoid orbits the Sun beyond Neptune." Reader FiReaNGeL links to a similar story at e! Science News.

The Phoenix Mars Lander has successfully deployed its robotic arm and tested other instruments including a laser designed to detect dust, clouds, and fog. The arm will be used to dig up samples of the Martian surface, which will be analyzed as a possible habitat for life. A camera on the arm will allow pictures to be taken of the ground directly beneath the lander. The camera has already seen what may be ice, which was exposed when the soil was disturbed by the landing. The data collected by the arm will be compared to recent findings which suggest that water on Mars may have been too salty for most known forms of life.

spandex_panda writes "There are a few pictures of the Mars Lander on the ground — you can see its parachute and its heat shield a few kilometers away, too. There's a very cool looking picture of it floating down, actually captured while it's in the air with its parachute out!" We also have a YouTube video all about the robot arm that will dig down and probably find a groundhog who we all hope will see his shadow.

Astronomers led by Simon Driver of Scotland's University of St. Andrews have discovered that interstellar dust shades us from as much as 50% of the light emitted by stars and galaxies. The scientists compared the number of galaxies we could see "edge-on" against the number which were "facing us," reasoning that dust would obscure more of the former, since we already receive less light from them. SPACE.com notes, "In fact, the researchers counted about 70 percent fewer edge-on galaxies than face-on galaxies." A NYTimes report provides some additional details: "Interstellar dust absorbs the visible light emitted by stars and then re-radiates it as infrared, or heat, radiation. But when astronomers measured this heat glow from distant galaxies, the dust appeared to be putting out more energy than the stars. 'You can't get more energy out than you put in, so we knew something was very wrong,' said Dr. Driver. The results also mean that there is about 20 percent more mass in stars than previously thought."

sciencehabit writes "New calculations suggest that black holes are not a one-way street. Anything that falls into them may eventually come out. The findings lend important support to quantum gravity, but fly in the face of Einsteinian relativity. They also support Stephen Hawking's reluctant admission that information couldn't be destroyed by black holes. Penn State researcher Ahbay Ashtekar was quoted saying, 'Once we realized that the notion of space-time as a continuum is only an approximation of reality, it became clear to us that singularities are merely artifacts of our insistence that space-time should be described as a continuum.' Let the physics infighting begin."

PHPNerd writes "Over at space.com is an interesting article about the first space lawyer. He graduated from the University of Mississippi. 'Any future space lawyer might have to deal with issues ranging from the fallout over satellite shoot-downs to legal disputes between astronauts onboard the International Space Station. The expanding privatization of the space sector may also pose new legal challenges [...] "We are particularly proud to be offering these space law certificates for the first time, since ours is the only program of its kind in the U.S. and only one of two in North America," said Samuel Davis, law dean at the University of Mississippi.'"

hackingbear writes "Unsatisfied by the reliance on American GPS navigation systems and not feeling much security joining the European Galileo system, China will expand its 4-satellite Beidou navigation system to a full-fledged, competitive, and encrypted system by 2010."

Loether writes "Space.com has a fun article about how astronauts aboard the ISS play 'sports' in zero gravity. It talks about learning how to throw in a straight line instead of the arc we all take for granted, relay races, and using large water filled bags as medicine balls. 'We realized that you could toss and catch and then go for a ride on this big thing as it takes you away.' The astronauts also put out a request for new ideas for space sports. Have any suggestions?"

eldavojohn writes "A recent meeting held by the Finnish Meteorological Institute has resulted in plans to build an electric solar sail that will circle the Earth, gaining speed to test its acceleration. The purpose? 'A flight out of the solar system to measure the gas, dust, plasma and magnetic field in the undisturbed interstellar space would perhaps be the "flagship" thing to do,' said Pekka Janhunen, a researcher developing the sail at the FMI. The details and papers of this project (over two years in the making) are also available. I certainly hope it will show more success than the launch of the similar U.S.-Russian venture and its subsequent complete failure."

AbsoluteXyro writes "According to a Space.com article, NASA scientists have discovered the smallest known black hole to date. The object is known as 'XTE J1650-500'. Weighing in at a scant 3.8 solar masses and measuring only 15 miles across, this finding sheds new light on the lower limit of black hole sizes and the critical threshold at which a star will become a black hole upon its death, rather than a neutron star. XTE J1650-500 beats out the previous record holder, GRO 1655-40, by about 2.5 solar masses."

eldavojohn writes "Is there life on Mars? Maybe not, but a better question might be whether or not it has ever existed on Mars? Scientists are claiming that the best indication for this will be in newly found evaporated salt deposits on Mars which they can use to check for cellulose. Here on earth, tiny fuzzy fibers have been found in salt dating back almost 250 million years making it the oldest known evidence of life on earth. Jack Griffith, a microbiologist from UNC, is quoted as saying, 'Cellulose was one of the earliest polymers organisms made during their evolution, so it pops out as the most likely thing you'd find on Mars, if you found anything at all. Looking for it in salt deposits is probably a very good way to go.'"

PRB_Ohio takes us to Space.com for a story about NASA's plutonium shortage, and how it may affect future missions to the far reaches of the solar system. The U.S. hasn't produced plutonium since 1988, instead preferring to purchase it from Russia. We discussed the U.S. government's plans to resume production in 2005, but those plans ended up being shelved. If NASA is unable to find an additional source, it could limit missions that take spacecraft too far from the Sun. Quoting: "Alan Stern, NASA associate administrator for science, ... said he believed the United States had sufficient plutonium-238 on hand or on order to fuel next year's Mars Science Lab, an outer planets flagship mission targeted for 2017 and a Discovery-class mission slated to fly a couple years earlier to test a more efficient radioisotope power system NASA and the Energy Department have in development. To help ensure there is enough plutonium-238 for those missions, NASA notified scientists in January that its next New Frontiers solicitation, due out in June, will seek only missions that do not require a nuclear power source."

bfwebster writes "Space.com has an article talking about the efforts to observe the arrival of the Phoenix lander on Mars this coming May using current Mars orbiters. This community will likely be intrigued to see the ways in which NASA is using existing landers and orbiters to prepare for, and then monitor, that landing. This includes using the landers Spirit and Opportunity to simulate transmissions from Phoenix as a testing procedure in advance of the actual landing; using the Odyssey orbiter as a high-speed data transmission link from Phoenix to Earth during the landing; and using the Mars Reconnaissance Orbiter and Mars Express orbiter as backup data stores for Phoenix data transmissions during the descent. How long until we get a terabyte solid-state dataserver (running IPv6, natch) in orbit around Mars?"

iamlucky13 writes "A minor academic debate among astronomers is the final fate of the earth. As the sun ages and enters the red giant stage of its life, it will heat up, making the earth inhospitable. It will also expand, driven by helium fusion so that its outer layers reach past the earth's current orbit. Previously it had been believed that the sun would lose enough mass to allow earth to escape to a more distant orbit, lifeless but intact. However, new calculations, which take into account tidal forces and drag from mass shed by the sun, suggest that the earth will have sufficiently slowed in that time to be dragged down to its utter destruction in 7.6 billion years. "

pha7boy writes "NASA has made a recent award of 171 million dollars to Orbital Sciences Corp. of Virginia in order to aid the company in developing a feasible space cargo delivery service. 'The US space agency intends to hold an open competition in the years ahead for actual space station cargo-delivery contracts, but Orbital of Dulles, VA, is one of two companies receiving financial help from NASA to develop their proposed systems. The other is Space Exploration Technologies of El Segundo, CA.'"

vm writes "NOVA's recent documentary, "Astrospies," was written and co-produced by journalist and NSA expert, James Bamford. It details the U.S. Air Force's orbiting spy station program begun in the 1960s, the Manned Orbital Laboratory. Designed from a heavily modified Gemini 2 capsule and launched from a Titan III booster rocket, MOL was basically intended to be a Hubble telescope pointed at Earth with the sole intention of collecting photo intelligence on the Soviets using an impressive array of optics and gyro balanced cameras operated onboard by specially trained astronauts. The lab was never launched, however, due to the competing Corona unmanned spy satellite program funded by NASA and the National Reconnaissance Office. Partly spurred by the success of the Apollo missions, the Soviets, meanwhile, sent cosmonauts to its own succesfully launched spy platform, the Almaz. In addition to an onboard film lab and a space-to-ground image relay system, it included an alarming first in manned space exploration; a 23mm aircraft cannon — which is rather ironic in light of Russia and China's recent attempts to ban space weaponry. At a time when we're still unearthing details about the post 9/11 domestic spying debacle, it's a fascinating look at the history of technology used to look over our neighbors' fences." There is more to the story but what these sorts of stories always make me wonder, is since this was the 60s, what are they doing NOW!

ChromaticDragon writes "Astronomers have crunched some numbers on a galaxy to discover that its rotation can be fully explained by the gravity of the observable matter — in effect, this galaxy seems to lack dark matter. This shouldn't come as a total surprise given that one of the stronger observations of Dark Matter was the Bullet Cluster where supposedly a good deal of Dark Matter and good old fashion regular matter had separated."

jc42 writes "Astronomers have been looking at the first images of asteroid 2007 TU24, the 250-meter asteroid that will pass 540,000 km from the Earth at 8:33 UTC (3:30 EST) Tuesday morning. So get your telescopes out; it's a 10th-magnitude object. Or just hold your breath as the time approaches. It might be sobering to consider that it was just discovered last October, and we know about maybe half of the objects like this in Earth-crossing orbits."

eldavojohn writes "There has long been speculation on why the Sun's surface is a mere ten thousand degrees while the atmosphere can reach millions. Space.com is reporting that the mystery has now been solved. Researchers looked for Alfven waves in the solar chromosphere and found them. Followup studies employing simulations demonstrated that the energetics work out to transfer energy from the Sun's surface to its overlying corona.. The magnetic waves may also be the power source behind the solar wind."

Brandee07 writes "Designed for a 90 day mission, the Spirit Mars Rover is starting its 4th year of exploration. Spirit's sister-module, Opportunity, will turn four on Jan 25. 'We never thought we'd still be driving these robots all over Mars,' said Mark Lemmon, a planetary scientist at Texas A&M University and member of the rover science team. 'We joked about driving Opportunity into Victoria Crater, but now we're there, and we're looking at doing even more science. Each day they still work is an amazing one.'"

butterwise writes to mention that astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a "death-star-like" beam of energy. The story also has a video with simulations, pictures, and explanations. "The 'death star galaxy,' as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos."

explosivejared writes "A private company by the name of Odyssey Moon has become the first team to complete registration for Google's Lunar X Challenge. They will likely be competing with several heavyweights in the field, as Carnegie Mellon University, along with many others, has already expressed an interest in the competition."

Josh Fink writes "Space.com is reporting that the International Space Station has a minor atmosphere leak. 'An inspection of a vestibule bridging the station's new Harmony connecting module and NASA's Destiny laboratory indicated a slight air leak of about three pounds (1.3 kilograms) per day ..A close-up inspection of the vestibule seal by the station's three-astronaut Expedition 16 crew using an ultrasonic leak detector found no trace of a leak on Wednesday, [NASA spokesperson Lynette Madison] said. Studies of the station's overall internal pressure also found no signs of decay, she added.' While this is yet another technical issue with the ISS, when will this end? I am all for the space program, but there have been some major issues lately."

eldavojohn writes "You may recall discussing Baikonur, the Kazakhstan city rented by Russia that has been used as a launch site for quite some time. Today, Putin has just approved construction of Vostochny between 2010 and 2018 which will be positioned in the far east of Russia to complement the Plesetsk Cosmodrome in the northern part of the country. This is not bad news for Kazakhstan as the director of the Russian Federal Space Agency has announced they plan to operate this facility alongside Baikonur."

njdube sent in this Space.com story about the money behind SETI that opens, "It's a risky long shot that burns up money and might never, ever pay off. So is searching for intelligent creatures on unseen worlds worth the candle? After all, aren't there better ways to use our monies and technical talents than trying to find something that's only posited to exist: sentient beings in the dark depths of space?"

mikesd81 writes "The rocketeers at Armadillo Aerospace, thwarted by engine problems and other mechanical failures, left this year's X Prize Cup empty-handed after their spacecraft burst into flames on liftoff Sunday. An attempt on Sunday to hop from launch and landing pads ended with the MOD craft bursting in flames shortly after engine ignition. This is the team's second attempt at the challenge in New Mexico, they were the only entrant in last year's event, which they also lost. Brett Alexander, Executive Director of Space Prizes and the X Prize Cup relayed a comment from John Carmack, leader of the Armadillo team: "Today is officially a bad day when it comes to our vehicle." The last attempt to win the $350,000 Level 1 prize on Sunday ended when the MOD vehicle had an engine fire, with pieces coming off, including disconnected cabling. Clearly, there was a fire on the pad that burned for a while — but then went out. The Armadillo team called a safety emergency, requesting fire truck assistance, Alexander said."

Genocaust writes "A stellar black hole much more massive than theory predicts is possible has astronomers puzzled. Stellar black holes form when stars with masses around 20 times that of the sun collapse under the weight of their own gravity at the ends of their lives. Most stellar black holes weigh in at around 10 solar masses when the smoke blows away, and computer models of star evolution have difficulty producing black holes more massive than this. The newly weighed black hole is 16 solar masses. It orbits a companion star in the spiral galaxy Messier 33, located 2.7 million light-years from Earth. Together they make up the system known as M33 X-7."

mrcgran writes "Space.com reports, "Almost one month after Japan's successful launch of the Kaguya lunar probe, the unmanned observatory has begun its first major activities in orbit around the moon. In addition to snapping its first lunar images, the probe jettisoned one of two 110-pound (50-kilogram) "baby" satellites that will help create a detailed gravity map of the moon." The major objectives of the "KAGUYA" mission are to obtain scientific data of the lunar origin and evolution and to develop the technology for the future lunar exploration. "KAGUYA" consists of a main orbiting satellite at about 100km altitude and two small satellites (Relay Satellite and VRAD Satellite) in polar orbit."

SkiifGeek brings to our attention a story that ran on space.com a few months back but didn't get much wider notice at the time. "The French have identified numerous objects in orbit that do not appear in the ephemeris data reported by the US Space Surveillance Network. Now, the US claims that if it doesn't appear in the ephemeris data, then it doesn't exist. The French insist that at least some of the objects they have found boast solar arrays. Therefore it seems that the French have found secret US satellites. While they don't plan to release the information publicly, they do intend to use it as leverage to get the US to suppress reporting of sensitive French satellites in their published ephemeris."

Raver32 sends us to space.com for first light on the design of New Mexico's Spaceport America. Quoting: "The winning design is the work of URS Corporation — a large design and engineering enterprise — teamed with Foster + Partners of the United Kingdom, a group with extensive experience in crafting airport buildings. When the 100,000 square-foot facility is completed — the centerpiece of the world's first, purpose-built, commercial spaceport — the structures will serve as the primary operating base for Sir Richard Branson's Virgin Galactic suborbital spaceliner, and also as the headquarters for the New Mexico Spaceport Authority."

Raver32 writes "Tuesday morning, Aug. 28 brings us the second total lunar eclipse of 2007. Those living in the Western Hemisphere and eastern Asia will be able to partake in at least some of this sky show. The very best viewing region for viewing this eclipse will fall across the Pacific Rim, including the West Coast of the United States and Canada, as well as Alaska, Hawaii, New Zealand and eastern Australia. All these places will be able to see the complete eclipse from start to finish. Europeans will miss out on the entire show, as the Moon will be below the horizon during their mid and late morning hours."
