Fermi Observation of Early Background Light Animation
This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi #39;s Large Area Telescope (LAT). During their journey, the number of randomly moving ultraviolet and optical photons (blue) increases as more and more stars are born in the universe. Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source.

Science Caf: Ken Storey on the biochemistry of winter hibernation
We all know that mammals are warm-blooded and that for humans a drop in core body temperature of only a few degrees can be lethal. However, such strict adherence to a high constant body temperature is not a feature of all mammals. Hibernators readily abandon this concept and let their bodies chill to near zero degrees Celsius while entering a deep torpor. Join Ken Storey, professor in the Departments of Chemistry and Biology, for a talk about the adaptations that allow some mammals to endure life in the cold and how our understanding of these mechanisms could lead to advances in medicine, organ preservation and long-term space flight. Where: Wild Oat Caf at 817 Bank Street. When: Wednesday, Nov. 7 from 6:30 pm to 7:30 pm The free 20-minute discussion will be followed by a question and answer session. The Science Caf series takes place every second Wednesday until Dec. 5, 2012. The Science Caf series is organized by the Faculty of Science at Carleton University to discuss relevant issues facing our society and how science can help solve real-world problems. Meet some of our award-winning faculty members and graduate students as they share their excitement about science with the community.

Yet Another Slow Motion Advisory Committee on Human Space Flight

The National Research Council has created the Committee on Human Spaceflight - yet another semi-annual effort to study and advise Congress on NASA's human space flight activities: "In accordance with Section 204 of the NASA Authorization Act 2010, the National Research Council (NRC) will appoint an ad hoc committee to undertake a study to review the long-term goals, core capabilities, and direction of the U.S. human spaceflight program and make recommendations to enable a sustainable U.S. human spaceflight program."

Do these congressionally-mandated NRC policy committees ever really say anything useful or new about space policy? These NASA efforts are quasi-regular exercises where a group of familiar names an a few new ones are brought together for a series of sedate meetings that last for more than a year. You see, congressional authorization committees direct NASA to pay for these studies when they feel that Congress needs a blue ribbon panel to produce verbiage that they can use to beat NASA and the current administration over the head when Congress feels that they are not being listened to.

Once completed, the policy reports are only cited if the have useful sentences that support (or seem to support) a niche position that one politician or committee may take. By definition, NRC reports are never controversial but rather embody lots of slow-motion consensus and inevitable watering down of important issues. Its not that these are substandard efforts by any means since the NRC is an impressive, competent organization. At most, however, these studies take a long time to conduct and are usually a blip on the radar when they issue their final document.

The NASA Authorization Act of 2010 was signed into law on 11 October 2010. It has taken more than 2 years for everyone to get around to starting this study. The start date listed for this committee is November 2012 and its report is due for delivery in May 2014. That's 1 year, 7 months. This NRC is responding to authorizing legislation passed in 2010 by the 111th Congress, with a committee now being requested by the 112th Congress, and its report will be presented to yet another Congress (113th) during the second year of a new presidential administration in mid-2014 - one where policies are in place that will differ from those in place when the task was assigned, with budgets that differ from initial conditions under which the study was undertaken.

Net result: the committee's advice will be out of synch with reality and somewhat overtaken by events having taken a total of 3 years, 7 months to complete. The soonest that a NASA budget could be crafted that took this committee's advice into account would be the FY 2016 budget request. NASA and OMB will interact on the FY 2016 budget during Fall 2014 and it won't be announced until early 2015 - 4 1/2 years after this committee and its advice was requested in the NASA Authorization Act 2010.

Further, this study is about the substance contained NASA Authorization Act of 2010. Authorization acts say lots of interesting and specific things that never come to pass when budgets and policies are actually crafted and enacted. At best, these NRC committees look at what NASA should do or could do - not what it will do - those decisions are made by a wholly different and far less disciplined process - one that operates much more swiftly than a multi-year advisory committee is going to be able to keep pace with.

If only the advisory process were more responsive to the issues in play - and done in real time - perhaps these committees could actually find their considered, expert advice work its way to actual implementation.

Oh yes: If Gov. Romney wins, he has said that he will convene his own blue ribbon panel to look at American space policy - and human spaceflight is clearly going to be one of the top issues addressed. That committee will likely finish with its task (much of its decisions having been pre-ordained by a Romney Administration) before the NRC team even gets a draft report out for internal review. Whose advice will prevail?

From http : "Kosmonaut Yuri Gagarin, with a displacement of 45.000 ton and two 9500 shp Kirov steam turbines, was launched from the Baltic Shipyard in 1971. With 230m in length and a beam of 31m Yuri Gagarin was only slightly smaller than the ill-fated RMS Titanic. She had an operation crew of over 300 who lived in relatively luxury (Soviet space scientists and technicians were often treated as royalty -- the cosmonauts as gods). Since space flight in the early 70s were high bursts of energy followed by long periods of waiting Yuri Gagarin was equipped to cater for this lifestyle. A 10.000 volume library, 120 laboratories/ workshops and a 300 seat lecture hall provided intellectual stimulation on the long journeys. An indoor football field and three swimming pools saw to it that the crew remained fit for their task. Besides the main task of tracking Soviet manned and unmanned space flight Yuri Gagarin was equipped to carry out its own experiments and research both in the upper atmosphere and space. The nature of their work saw the crew enduring prolonged oceanic journeys and live onboard might have been less glamorous than that of those who worked in the Soviet Union, but when Yuri Gagarin entered a friendly port (the USSR had many friends around the world and the ship was often moored in ...From:PinkNoiseManufacturyViews:8 0ratingsTime:06:57More inScience Technology

SpaceX tests its precision landing rocket

It's been a busy week at SpaceX, with the company passing milestones for its manned space programme, completing a test flight of its precision landing system and welcoming its latest Dragon back home from orbit.

The Californian company has finished with the first three performance milestones set out by Nasa for the agency's Commercial Crew Integrated Capability programme. The CCiCap initiative is similar to the commercial cargo development programme SpaceX finished earlier this year, but instead the programme is designed for carrying crew to low Earth orbit.

Right now the only way for Nasa to send astronauts to the ISS is via the Russian Soyuz. From the beginning, SpaceX has designed both the Falcon 9 booster rocket and the Dragon spacecraft to be capable of manned space flight. And last week the company presented Nasa with its plans for an integrated systems requirements review, the third milestone for the CCiCap programme.

"These initial milestones are just the beginning of a very exciting endeavour with SpaceX," said Ed Mango, Nasa's Commercial Crew Program manager. "We expect to see significant progress from our three CCiCap partners in a fairly short amount of time."

The two other companies working with Nasa on the CCiCap are Boeing and Sierra Nevada Corporation.

Eventually SpaceX wants to employ a fully reusable space launch system. Currently, the Falcon 9 booster rocket isn't put back into service after splashing down in the Atlantic at the end of the first stage. The company has pointed out in the past that airlines don't throw away the airplane after every flight, and it believes one of most important achievements to greatly reducing the cost of orbital flight is to be able to reuse as much of the vehicle as possible after a launch.

In the future SpaceX plans to use rocket engines to allow the Falcon 9 to return to Earth in a controlled flight, with a precision landing at a specified landing site. On 4 November SpaceX founder Elon Musk sent out a video showing the latest (short) flight testing the company's precision landing rocket.

"First flight of 10 story tall Grasshopper rocket using closed loop thrust vector & throttle control," Musk tweeted.

Similar to the previous Grasshopper flight, the rocket lifts off the pad for an eight second flight at a height of 5.4 metres and returns safely to the ground. While the flight from the 1 November might not look like much, a controlled landing from even a low height as seen in the video is no easy task. The closed loop thrust vector and throttle are part of the automated controls for the Grasshopper. The Falcon 9 and Dragon both use automated controls for all phases of flight (with manual override capabilities) including the final docking with the ISS.

The Grasshopper is a suborbital test vehicle with a wider landing gear structure at its base to allow for vertical take off and landing capability. Eventually the landing gear is expected to fold up flush with the first stage during flight and be extended again for landing.

NASA's space launch system using futuristic technology to build the next generation of rockets

(Phys.org)NASA's Marshall Space Flight Center in Huntsville, Ala. is using a method called selective laser melting, or SLM, to create intricate metal parts for America's next heavy-lift rocket. Using this state-of-the-art technique will benefit the agency by saving millions in manufacturing costs.

NASA is building the Space Launch System or SLSa rocket managed at the Marshall Center and designed to take humans, equipment and experiments beyond low Earth orbit to nearby asteroids and eventually to Mars.

SLM is similar to 3-D printing and is the future of manufacturing.

"Basically, this machine takes metal powder and uses a high-energy laser to melt it in a designed pattern," says Ken Cooper, advanced manufacturing team lead at the Marshall Center. "The laser will layer the melted dust to fuse whatever part we need from the ground up, creating intricate designs. The process produces parts with complex geometries and precise mechanical properties from a three-dimensional computer-aided design."

There are two major benefits to this process, which are major considerations for the Space Launch System Program: savings and safety.

"This process significantly reduces the manufacturing time required to produce parts from months to weeks or even days in some cases," said Andy Hardin, the integration hardware lead for the Engines Office in SLS. "It's a significant improvement in affordability, saving both time and money. Also, since we're not welding parts together, the parts are structurally stronger and more reliable, which creates an overall safer vehicle."

The emerging technology will build parts for America's next flagship rocket more affordably and efficiently, while increasing the safety of astronauts and the workforce. Some of the "printed" engine parts will be structurally tested and used in hot-fire tests of a J-2X engine later this year. The J-2X will be used as the upper stage engine for the SLS.

The goal is to use selective laser melting to manufacture parts on the first SLS test flight in 2017.

The agency procured the M2 Cusing machine, built by Concept Lasera division of Hoffman Innovation Group of Lichtenfels, Germany to perform the selective-laser-manufacturing.

Saudi- Conference logo recalls Prince Sultan's historic 1985 space flight

(MENAFN - Arab News) Prince Sultan bin Salman, the first Muslim and first Saudi in space, recalled recently how the new conference logo first originated with the 1989 ASE Congress hosted in Riyadh, just four years after his historic flight into space.

With Prince Khalid Al-Faisal, Prince Sultan developed the illustration that served as a logo for the event poster.

The painting depicts the traditional desert Arab in the natural environment he inhabits - the island Earth in the vastness of space - relying on his camel, his Saluki hunting dog, the date palm and contemplating the heavens as a source of spiritual guidance, inspiration and navigation. The image represents the natural unity that binds humanity to its surroundings.

The Kingdom has come a long way since then, and the 25th ASE Congress logo is designed to reflect that.

Prince Sultan's memorable flight into space aboard the space shuttle Discovery paid dividends well beyond the launch of ARAB SAT and the scientific achievements of that flight. The results are achievements that the Kingdom can be proud of as its youths are now up to date with the latest technologies, follow the latest scientific and space achievements on multiple information processing and communication platforms, confirming that the knowledge-based society is not coming to the Kingdom, it is actually already here and on its way to driving further achievements and empowerment for its people.

The 2012 logo attempts to capture the new spirit in the Kingdom from the early days when the people of Saudi Arabia observed space from the desert lands, to the present where Saudis observe their land from space. The comfort and knowledge of enabling technologies such as satellites, space shuttles, and other space platforms, is ever expanding in the Kingdom and among its scientists.

The trail blaze of actual STS 51 G image at takeoff behind the astronaut's shoulder is a reminder of the historic launch of STS51 G and its lasting impact on the Kingdom, Arab and the Muslim world. Riyadh the center of decision-making then, and home of the 25th Congress, is highlighted by a bright light emanating from the Kingdom.

Youth represents a large segment of Saudi society, and the adoption of digital technologies and the wide use of the World Wide Web to learn and communicate is second nature to Saudi youth. These are symbolized with the binary code zeros and ones, while the Web is incorporated with the iconic "@" sign.

The logo incorporates the symbols of this era and the Kingdom's vibrant evolving society as it transforms itself into a world class, knowledge-based society.
