Ponca City, We Love You writes "Space.com reports that over the weekend, a giant booster – a Delta 4 Heavy rocket — carrying a secret new spy satellite for the US National Reconnaissance Office roared into space to deliver into orbit what one reconnaissance official has touted as 'the largest satellite in the world.' The Delta 4 Heavy rocket is the biggest unmanned rocket currently in service and has 2 million pounds of thrust, capable of launching payloads of up to 24 tons to low-Earth orbit and 11 tons toward the geosynchronous orbits used by communications satellites. The mammoth vehicle is created by taking three Common Booster Cores — the liquid hydrogen-fueled motor that forms a Delta 4-Medium's first stage — and strapping them together to form a triple-barrel rocket, and then adding an upper stage. The exact purpose of the new spy satellite NROL-32 is secret, but is widely believed to be an essential eavesdropping spacecraft that requires the powerful lift provided by the Delta 4-Heavy to reach its listening post. 'I believe the payload is the fifth in the series of what we call Mentor spacecraft, a.k.a. Advanced Orion, which gather signals intelligence from inclined geosynchronous orbits,' says Ted Molczan, a respected sky-watcher who keeps tabs on orbiting spacecraft. Earlier models of the series included an unfurling dish structure about 255 feet in diameter with a total spacecraft mass of about 5,953.5 pounds, costing about $750 million and designed to monitor specific points or objects of interest such as ballistic missile flight test telemetry."

Ponca City writes "JR Minkel writes on Space.com that as NASA celebrates the 10th anniversary of astronauts living on the space station — and with construction essentially complete — the question remains: will the International Space Station ever really pay off scientifically? The space agency contends that the weightless environment provided by the station offers a unique way of unmasking processes of cell growth and chemistry that are hidden on Earth, but some critics don't see a zero gravity laboratory as filling a crucial scientific need. Gregory Petsko, a biochemist at Brandeis University, says the only basic science justification he has ever heard for the station is that protein molecules form superior crystals in the microgravity of space than they do on Earth and a best-case scenario, in terms of return on investment, would be if a space-grown crystal were used to design a blockbuster pharmaceutical drug that worked by precisely targeting one of those proteins. Naturally NASA sees things differently. 'I think those who are naysayers haven't given us a chance — haven't given us enough time to show what we can do. We're just now turning the path to be able to go full force on our science. In the past we had to fit it in around assembly, we didn't have the facilities available, and the crew was always busy.'"

As the space shuttle program winds down, 1,200 NASA workers were laid off today, and thousands more will lose their jobs in the months ahead. "Many shuttle workers held out hope that they could find new jobs in the Constellation program, which would have included two new rocket systems and a new crew module to transport astronauts into space. From the beginning, Constellation was plagued by underfunding. This year, Obama killed the program's future funding because of budget overruns and because it was behind schedule. That could affect more than 20,000 workers along Florida's space coast, according to Rice." This comes alongside news that Lockheed Martin has stopped work at the production plant that supplied 136 external fuel tanks for the space shuttles since 1973.

An anonymous reader writes "Much fanfare has been made about manned missions to moons and planets, but little has been done about travel to the asteroids — until now. NASA is working on plans for a trip to the asteroids by 2025. This type of mission has great potential for positive economic return based on the fact that no effort has to be spent on getting in and out of a distant planet's gravity well. Yes, we should go to the planets, but we should master mining the asteroid belt for resources first because it is easiest. What do you think?"

eldavojohn writes "On Saturday at 8pm GMT, the crew of the International Space Station awoke to alarm bells as one of two ammonia pumps shut down due to a spike in power. Their backup cooling (Loop B) is functioning as designed and NASA released an official statement: 'The crew is in no danger, but will need to work additional troubleshooting on Sunday to keep the station in a stable configuration, including the installation of a jumper cable to maintain proper cooling to the Zarya module in the Russian segment.'"

Hugh Pickens writes "Scientists at the University of Sheffield have discovered the most massive stellar giant, R136a1 measured at 265 solar masses, using the European Southern Observatory's Very Large Telescope in Chile and data from the Hubble Space Telescope. It's in the Tarantula Nebula in the Large Magellanic Cloud, a small 'satellite' galaxy which orbits the Milky Way. Previously, the heaviest known stars were around 150 times the mass of the Sun, known as the 'Eddington Limit,' and this was believed to be close to the cosmic size limit because as stars get larger, the amount of energy created in their cores grows faster than the force of gravity which holds them together. 'Because of their proximity to the Eddington Limit they lose mass at a pretty high rate,' says Professor Paul Crowther, the chief researcher in the Sheffield team. Hyper-stars like R136a1 are believed to be formed from several young stars merging together, and are only found in the very heart of stellar clusters. R136a1 is believed to have a surface temperature of more than 40,000 degrees Celsius, and is 10 million times brighter than the Sun. Crowther adds that R136a1 is about as big as stars can get. 'Owing to the rarity of these monsters, I think it is unlikely that this new record will be broken any time soon.'"

The thermosphere layer of earth's atmosphere begins 80 to 90 kilometers above the surface and extends several hundred kilometers into the sky; it is the home to numerous satellites and the International Space Station. It is known that the thermosphere occasionally cools and contracts, but a recent study of satellite orbital decay (due to light atmospheric drag) found that the contraction during 2008 and 2009 was significantly more severe than expected, leaving researchers at a loss for how to explain it. From Space.com: "This type of collapse is not rare, but its magnitude shocked scientists. 'This is the biggest contraction of the thermosphere in at least 43 years,' said John Emmert of the Naval Research Lab, lead author of a paper announcing the finding in the June 19 issue of the journal Geophysical Research Letters. 'It's a Space Age record.' The collapse occurred during a period of relative solar inactivity — called a solar minimum from 2008 to 2009. These minimums are known to cool and contract the thermosphere, however, the recent collapse was two to three times greater than low solar activity could explain."

Several readers have sent word that today NASA launched Moonbase Alpha, an online game with single- and multi-player capability that "allows participants to step into the role of an exploration team member in a futuristic 3-D lunar settlement." The game is available now through Steam for free. Moonbase Alpha was built as a precursor to an upcoming NASA MMO called Astronaut: Moon, Mars & Beyond, and they hope it will be "a proof of concept to show how NASA content can be combined with a cutting-edge game engine to inspire, engage and educate students about agency technologies, job opportunities and the future of space exploration."

FleaPlus writes "Following up on a story from a few days ago about an unmanned Russian cargo ship's initial aborted attempt at docking with the International Space Station, Space.com reports that the vehicle made a second pass on July 4, which succeeded. Russian engineers believe the initial abort was triggered when the (normally reliable) Progress spacecraft detected interference between a remote control system on the ISS and Progress's camera. It successfully docked on the second try by using the autonomous system instead."

An anonymous reader noted a report confirming the first ever exoplanet actually photographed from telescopes on earth. Every other exoplanet so far 'observed' has been done by measuring wobbles of stars pulled by planetary gravity. But this one is a photograph. And that's just plain cool.

FleaPlus writes "Boeing has released a number of new details on its CST-100 manned space capsule, being developed in collaboration with commercial space station builder Bigelow Aerospace. Competing with SpaceX's Dragon capsule, the vehicle is designed to be compatible with existing Atlas V, Delta IV, and Falcon 9 rockets, and is planned to carry seven people in a capsule 'a little smaller than Orion, but a little bigger than Apollo.' Funding was jump-started this year with $18M of fixed-price Commercial Crew Development money from NASA, which requires completion of several fabrication and demonstration milestones this year (heat shield, escape system, landing tests, etc.) in order to get the full payment."

dangle sends in an update from the borderland of Sol. "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. 'Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later,' said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. 'It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery.' The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system."

FleaPlus writes "Water ice was recently discovered on the large asteroid 24 Themis, and Space.com discusses proposals for producing fuel from asteroid ice. NASA and the President recently announced plans for robotic precursor missions to asteroids (and a human mission by 2025), as well as a funding boost for R&D to develop techniques like in-situ resource utilization. Since most of the mass of a beyond-Earth mission is fuel, refueling in orbit would be a huge mass- and cost-saver for space exploration (especially if fuel can be produced in space), but a large unknown is how to effectively extract water in an environment lacking gravity."

PSandusky writes "NASA is preparing to make use of Aquarius, the underwater laboratory off Key Largo, for an extended period of time to research the effects of isolation in habitats situated in extreme environments. Planned areas of research include extravehicular activity logistics and crew health and performance. According to NASA's factsheet (PDF), the mission will include some communication with schools and social media sites. "

eldavojohn writes "The Hubble Telescope's successor reached a milestone today as it passed a critical design review. The James Webb Space Telescope was originally set to launch in 2013 but has run about $1B over budget and has been pushed back to a 2014 launch. Today's good news means that there shouldn't be further delays as the JWST has accomplished all science and engineering requirements for all mission-critical design functionality. Scientists, of course, think these delays and costs 'pale in comparison to the secrets of the universe the James Webb Space Telescope is expected to unlock.' These are exciting times for many realms of science, even if we're somewhat saddened by it being the loyal Hubble's twilight hours."

FleaPlus writes "The Rocket Racing League demonstrated two of their new 'Mark III' X-Racer rocketplanes at an air show in Tulsa, Oklahoma. Besides making for a fun show, the League also pushes the boundaries for reusable and easily maintainable rocket engines. (The X-Racer's liquid oxygen and ethanol rocket engine was made by John Carmack's Armadillo Aerospace, which recently released a video showcasing some of the rockets they've launched and landed in the past year.)"

FleaPlus writes "The US Air Force is currently preparing for the launch of the secretive X-37B OTV-1 (Orbital Test Vehicle 1) spaceplane, which was transferred from NASA to DARPA back in 2004 when NASA opted to focus its budget on lunar exploration. The reusable unmanned spaceplane is set to launch in April on top of a commercial Atlas V rocket, orbit for up to 270 days while testing a number of new technologies, reenter the atmosphere, then land on auto-pilot in California."

FleaPlus writes "The White House has announced that on April 15 the President will be visiting Florida to host a conference on the Administration's 'new vision for America's future in space,' which is focused on developing new technologies and capabilities needed for sustainable exploration of 'the Moon, asteroids, and eventually Mars.' The White House's plans for reinvigorating NASA are facing vocal opposition from several congressmen in Florida, Texas, and Alabama, due to its outright cancellation of the Constellation/Ares program, which was found to be 'fundamentally un-executable' but is/was an important source of jobs in many areas."

eldavojohn writes "New observations from NASA's Fermi Gamma-ray Space Telescope reveal that our assumptions about the 'fog' of gamma rays in our universe are not entirely explained by black hole-powered jets emanating from active galaxies — as we previously hypothesized. For now, the researchers are representing the source of unaccounted gamma rays with a dragon (as in 'here be') symbol. A researcher explained that they are certain about this, given Fermi's observations: 'Active galaxies can explain less than 30 percent of the extragalactic gamma-ray background Fermi sees. That leaves a lot of room for scientific discovery as we puzzle out what else may be responsible.' And so we reopen the chapter on background gamma-rays in the science textbooks and hope this eventually sheds even more light on other mysteries of space — like star formation and dark matter."

HockeyPuck writes "According to Space.com the amount of space junk is getting worse. 'A head-on collision was averted between a spent upper stage from a Chinese rocket and the European Space Agency's (ESA) huge Envisat Earth remote-sensing spacecraft. [...] But what if the two objects had tangled? Such a space collision would have caused mayhem in the heavens, adding clutter to an orbit altitude where there are big problems already, said Heiner Klinkrad, head of the European Space Agency's Space Debris Office in Darmstadt, Germany."

Gary W. Longsine writes "Five contracts have been awarded by NASA today, to firms exploring different aspects of the effort to develop a private launch industry for people to low earth orbit. Today's winners include: Sierra Nevada Corp (aka 'SpaceDev') for the Dream Chaser; Boeing in cooperation with Bigelow on a capsule design; United Launch Alliance (Boeing and Lockheed Martin) to explore safety issues related to upgrading Atlas and Delta rockets to human flight safety standards; Blue Origin to build a launch escape system; and Paragon Space Development Corp for 'air vitalization' (aka life support). Will the forecast $6 Billion allocation over five years be enough to inspire private industry to develop not one, but two human rated launch systems (a capsule, and the lifting body Dream Chaser)? NASA clearly wants competition in the private market, so they seek more than one vendor."

Hugh Pickens writes "Space.com has a piece about changing theories of planet migration. The classic picture suggests that planets like Earth should have plummeted into the sun while they were still planetesimals, asteroid-sized building blocks that eventually collide to form full-fledged planets. 'Well, this contradicts basic observational evidence, like We. Are. Here,' says astronomer Moredecai-Mark Mac Low. Researchers investigating this discrepancy came up with a new model that explains how planets can migrate as they're forming and still avoid a fiery premature death. One problem with the classic view of planet formation and migration is that it assumes that the temperature of the protoplanetary disk around a star is constant across its whole span. It turns out that portions of the disk are opaque and so cannot cool quickly by radiating heat out to space. So in the new model, temperature differences in the space around the sun, 4.6 billion years ago, caused Earth to migrate outward as much as gravity was trying to pull it inward, and so the fledgling world found equilibrium in its current, habitable, orbit. 'We are trying to understand how planets interact with the gas disks from which they form as the disk evolves over its lifetime,' adds Mac Low. 'We show that the planetoids from which the Earth formed can survive their immersion in the gas disk without falling into the Sun.'"

thomst writes "A team of researchers from Harvard and MIT announced at the 215th meeting of the American Astronomical Society a new theoretical model of how the super-massive black hole at the center of the Milky Way consumes gas from surrounding star clusters, based on a million seconds of observation by the orbital Chandra X-ray telescope. Astronomers had previously believed that the object, known as Sagittarius A* (pronounced 'Sagittarius A-Star') consumed only around one percent of the gases it stripped from the star clusters around it, but the new model reduces its consumption to 0.01 percent (i.e. — two orders of magnitude). Physorg.com's uncredited reporter gets the story right, while space.com's Andrea Thomspon clearly doesn't understand the mechanism behind the phenomenon (essentially, thermal conduction from the extremely-hot accretion disk heats the surrounding gas, causing it to expand, and thus move away from Sagittarius A*'s gravity well)."

eldavojohn writes "With the problem of moving conventional rocket fuel to the Moon and Mars on their minds, researchers from Purdue and Penn State successfully tested and demonstrated the use of aluminum-ice (ALICE) as fuel. In a paper from last August they outlined how it would work (PDF), and now they know it does. Space.com also has more information on the paper and how nano-scale aluminum functions as a fuel."

eldavojohn writes "Both the EU and US are using a strategy to merge what used to be two separate searches: the search for exoplanets that may harbor life and the search for dark energy. In an effort to develop 'robust, low-risk missions that maximize the scientific return,' the article analyzes how, without any changes, a space-based dark energy telescope could also check for microlensing events indicating an exoplanet."

GringoChapin writes in with coverage from Space.com on the Leonid meteor shower, adding "Folks from the United States will want to start watching at 0100 Pacific, 0400 Eastern, and those in Europe from 0100 local time until dawn." "One of the best annual meteor showers will peak in the pre-dawn hours Tuesday, and for some skywatchers the show could be quite impressive. The best seats are in Asia, but North American observers should be treated to an above average performance of the Leonid meteor shower, weather permitting." Sky and Telescope's coverage is excellent as usual, and they also have tips for beginning and advanced meteor observers.

DynaSoar writes "NASA's new Ares I-X rocket is undergoing final preparations for its planned launch test Tuesday, October 27. Launch time is scheduled for 8 AM EDT (1200 GMT). As of noon Monday it appeared that there was a 60% chance of showers and/or high altitude clouds interfering. However, the launch has a an eight hour window of opportunity through 2000 GMT, and would require only 10 minutes of clear skies within that time to fly. Of interest to engineering types, both those who favor the new vehicle's design and its critics, will be to see whether the predicted linear 'pogo stick' oscillation will occur, and whether the dampening design built into it prevents damaging and possibly destructive shaking. Extensive coverage is being presented by Space.com; for NASA TV streaming video, schedules and downlink information, visit nasa.gov/ntv." Update 15:37 GMT by timothy: The weather did not cooperate; today's planned launch has been scrubbed.

Nethemas the Great writes "Information has leaked ahead of the scheduled NASA press conference tomorrow that we have found unambiguous evidence for water on the moon. From the article, 'Since man first touched the moon and brought pieces of it back to Earth, scientists have thought that the lunar surface was bone dry. But new observations from three different spacecraft have put this notion to rest with what has been called "unambiguous evidence" of water across the surface of the moon.'"

eldavojohn writes that though gravitational waves are "predicted to exist by Einstein's Theory of General Relativity, the initial tests run by the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO) failed to find anything. It doesn't disprove their existence although it does rule out a subset of string theory. From the article, 'For example, some models predict the existence of cosmic strings, which are loops in space-time that may have formed in the early universe and gotten stretched to large scales along with the expansion of the universe. These objects are thought to produce bursts of gravitational waves as they oscillate. Since no large-amplitude gravitational waves were found, cosmic strings, if they exist at all, must be smaller than some models predict.' The scientists working in Washington and Louisiana (in tandem to rule out flukes) will now move on to Advanced LIGO which will analyze a volume of space 1,000 times larger. If they don't find any gravitational waves in that experiment, the results will be more than unsettling to many theorists."

jbdigriz writes "Leonard David has a followup piece to his original story, referenced here on June 22nd ('US Military Blocks Data On Incoming Meteors'). Air Force Brig. Gen. Robert Rego explains his decision to suspend the meteor data sharing program due to 'loopholes' in the informal arrangement. He and Congressman Dana Rohrabacher hold out some hope that the program will resume on a more secure basis at some unspecified but not too distant point."

An anonymous reader sends news that TerreStar-1, the largest satellite ever made for the purpose of telecommunications, successfully launched earlier this week from a European spaceport. Its launch weight was 6,910 kg, and it is "distinguished by a giant, 60-foot (18-meter) wide S-band antenna that will be unfurled in the coming weeks. Once the satellite's two solar wings are deployed, TerreStar-1 is expected to have a wingspan of about 106 feet (32.4 meters). ... It is designed to provide mobile voice and data communications in North America to smartphone-size handsets using the 2-gigahertz, or S-band, portion of the radio spectrum. The system is designed to function with a network of ground-based signal amplifiers to permit service in areas the satellite cannot reach, such as urban canyons and areas outside the line-of-sight view of the spacecraft." Video and details of the launch are available from the ESA.

eldavojohn writes "While a lot of people are wondering if commercial spaceflight will ever make it, Spaceport America is holding its groundbreaking ceremony today. You can watch it live at their site at 11am MST. The spaceport is aiming for a diverse clientele, including the delivery of small national security purpose satellites into Earth orbit as well as research and development for scientific purposes. After getting their FAA license and securing funding, the 27 square mile development project has officially begun. The target date for completion is the end of 2010 — let's all hope for success in the milestone goal!"

eldavojohn writes "Winning the lottery requires incredible luck and one in a million odds. So does getting hit by a falling space rock. A 14-year-old German boy was granted a three-inch scar by the gods. A pea-sized meteorite smote young Gerrit Blank's hand before leaving a foot-sized crater on the road. The boy's account: 'At first I just saw a large ball of light, and then I suddenly felt a pain in my hand. Then a split second after that there was an enormous bang like a crash of thunder. The noise that came after the flash of light was so loud that my ears were ringing for hours afterwards. When it hit me it knocked me flying and then was still going fast enough to bury itself into the road.' Curiously, the rock was magnetic, and tests were done to verify it is extraterrestrial. The Telegraph notes the only other recorded event of a meteorite striking a person was 'in November 1954 when a grapefruit-sized fragment crashed through the roof of a house, bounced off furniture and landed on a sleeping woman.' Space.com lists a few more anomalies and we discussed the probability of these things downing aircraft recently."

eldavojohn writes "The Hubble Constant is used for many things in astrophysics: from determining how fast things are moving away from us, to the total volume of the universe, to predicting how our universe will end. The current best value for the Hubble Constant is 74.2 ± 3.6 (km/s)/Mpc according to recent conventional methods and the recently restored Hubble Telescope. Most astronomers agree that that's within 10% of its actual value. Researchers now claim that they might be able to get to 3% using water molecules in galactic disks to act as masers that amplify radio waves, to analyze galaxies seven times as far away as the current measurements. The further away the 'standard candle' is, the more assured they can be that local effects are not skewing the measurements. From one of the researchers: 'We measured a direct, geometric distance to the galaxy, independent of the complications and assumptions inherent in other techniques. The measurement highlights a valuable method that can be used to determine the local expansion rate of the universe, which is essential in our quest to find the nature of dark energy.' Once the Square Kilometer Array is completed, they hope to get even closer to the actual value."

An anonymous reader points out that Congress has quietly begun dismantling NASA's manned space flight program. "Other recommendations contained in the bill include a $77million reduction in NASA's proposed space operations budget, which includes the space shuttle and international space station; a $6 million reduction in science; and a $332 million shift in funds from the Cross Agency Support account to a new budget line-item included in the subcommittee's mark. Dubbed Construction and Environmental Compliance, the new account would be funded at $441 million. Congressional aides said the new line item and accompanying funds are aimed at consolidating NASA's various construction efforts into a single pot of money."

Trunks writes "No doubt trying to ride the hype train that's currently going for the new Star Trek film, Space.com has a new article detailing how warp drive may not be impossible to acheive. From the article: '"The idea is that you take a chunk of space-time and move it," said Marc Millis, former head of NASA's Breakthrough Propulsion Physics Project. "The vehicle inside that bubble thinks that it's not moving at all. It's the space-time that's moving." One reason this idea seems credible is that scientists think it may already have happened. Some models suggest that space-time expanded at a rate faster than light speed during a period of rapid inflation shortly after the Big Bang. "If it could do it for the Big Bang, why not for our space drives?" Millis said.' Simple, right?"

AndreV writes "We've entered into an extraterrestrial quid pro quo with our Northern neighbors: After celebrating 25 years of the Canadarm's first venture into space, NASA has reached out (so to speak) to the Canadian Space Agency and begun research and development on a new generation of robotic arms, which would ultimately be used for the US agency's Orion Crew Exploration Vehicle that will provide transportation for Moon missions and jaunts to the international space station. In exchange, Canada will trade the robotic-limb technology's use on Orion and other future US-manned spacecraft for flight time for Canadian astronauts. And seeing solid results shouldn't be far off — the engineering company designing the bionic branch, responsible for the previous Canadarms, has already begun investigating the effects of zero gravity on their components. (Another forward-looking project being bartered for astronaut time is a rover for the Moon and Mars.) Fair trade?"

WindBourne writes "China will be launching 2 new space stations this next year. One is for their civil program (as run by the military), while the second is openly for the military. It appears that there will be multiples of the military version to be launched in 2010, and that they are developing the same US Air Force Manned Orbiting Laboratory (MOL) that was canceled in 1969. In addition, it appears that China is accelerating their timelines on a number of the earlier space announcements."

adeelarshad82 writes to point out that details have been provided for President Obama's proposed $18.7 billion in funding for NASA in 2010 (up from $17.2 billion in 2008). Quoting: "The budget calls on NASA to complete International Space Station construction, as well as continue its Earth science missions and aviation research. Yet it also remains fixed to former President George W. Bush's plan to retire the space shuttle fleet by 2010 and replace them with the new Orion Crew Exploration Vehicle, which would fly astronauts to the space station and return them to the moon by 2020. The outline does make room for an extra shuttle flight beyond the nine currently remaining on NASA's schedule, but only if it is deemed safe and can be flown before the end of 2010."

eldavojohn writes "Obama's proposed ban on space weapons is a complete 180 from George W. Bush's stance on them. Space.com looks at the two sides of the issue and quotes Michael Krepon explaining, 'The Bush administration rejected space diplomacy. We refused to negotiate on any subject that could limit US military options. We have a shift from an administration that was very dismissive of multilateral negotiations [as a whole], to an administration that is open to that possibility if it improves US national security.' You may recall discussing the necessity of space based weapons and Michael Krepon from 2005."

FleaPlus writes "Popular Mechanics reports that a 'renegade' group including NASA engineers has met with President-Elect Obama's space transition team to present information on the DIRECT architecture for launching NASA missions after the Space Shuttle is retired. According to the group, DIRECT's Jupiter launch system will be safer, less expensive, better-performing, and be ready sooner than the Ares launch system NASA is currently developing, while still providing jobs for much of the existing shuttle workforce. Meanwhile, it's expected that current NASA head and adamant Ares supporter Michael Griffin will be replaced by a new NASA administrator."

eldavojohn writes "Space.com has a blog on Russia's Phobos-Grunt project designed to explore the planet further. He voices concerns about part of this exploration that is dubbed LIFE (Living Interplanetary Flight Experiment) and backed by The Planetary Society that involves sending several samples of Earth's hardiest microbes to see if they can survive the round trip voyage. Space.com's correspondent Leonard David did some legwork to ensure that The Outer Space Treaty of 1967 was being upheld as it prevents cross-contamination between planets and receives some interesting responses from experts on this mission. The Phobos-Grunt mission will also deploy a Chinese sub-satellite 'Firefly-1,' which will attempt to figure out how water on Mars disappeared. Unfortunately, The United States is not taking part in Phobos-Grunt."

HanzoSpam sends us this story from Space News, which begins: "US President-elect Barack Obama's NASA transition team is asking US space agency officials to quantify how much money could be saved by canceling the Ares 1 rocket and scaling back the Orion Crew Exploration Vehicle next year. ... The questionnaire, 'NASA Presidential Transition Team Requests for Information,' asks agency officials to provide the latest information on Ares 1, Orion and the planned Ares 5 heavy-lift cargo launcher, and to calculate the near-term close-out costs and longer-term savings associated with canceling those programs. The questionnaire also contemplates a scenario where Ares 1 would be canceled but development of the Ares 5 would continue. While the questionnaire, a copy of which was obtained by Space News, also asks NASA to provide a cost estimate for accelerating the first operational flight of Ares 1 and Orion from the current target date of March 2015 to as soon as 2013, NASA was not asked to study the cost implications of canceling any of its other programs, including the significantly overbudget 2009 Mars Science Laboratory or the James Webb Space Telescope."

The biggest one will be the shuttle plan: do we retire the shuttle fleet or keep it on for more missions? If it is retired, we would have to rely on another country to bring our astronauts into space between 2010 and 2015 as a new fleet is built. Will Obama hold true on his $2 billion pledge to NASA?"
