NASA PICKS REVOLUTIONARY SPACE TECH PROPOSALS FOR DEVELOPMENT

FROM: NASA
　
WASHINGTON -- NASA's Space Technology Program has selected five technologies that could revolutionize America's space capabilities. In March, NASA issued a call for proposal focused on sudden and unexpected innovations that hold a potential for providing a "game-changing" impact on the efficiency and effectiveness of the agency's space capabilities. NASA has selected the following proposals for funding:
　
--"Representing and Exploiting Cumulative Experience with Objects for Autonomous Manipulation," University of Massachusetts, Amherst. This technology could improve autonomous robotic operations using artificial intelligence during deep space missions. --"Lightweight High Performance Acoustic Suppression Technology Development," NASA's Jet Propulsion Laboratory, Pasadena, Calif. This technology could suppress acoustic environments during launch. By reducing vibrations by acoustic suppression during launch, the amount of prelaunch vibration stress testing for onboard instruments also could be reduced.
　
--"Fast Light Optical Gyroscopes for Precision Inertial Navigation," NASA's Marshall Space Flight Center, Huntsville, Ala. This technology could enhance navigation capabilities for spacecraft by improving the performance of existing gyroscopes by a factor of 1,000. --"EHD-Based Variable Conductance Thermal Interface Material," The Boeing Company, El Segundo, Calif. The development of this thermal material could provide better heat management for spacecraft. --"Membrane Enabled Reverse Lung," Oceaneering Space Systems, Houston. This technology could reduce the number of life support systems needed for astronauts.
　
"NASA's Space Technology Program is enabling our future in space by investing in revolutionary and game-changing technologies that could open new doors for how we live, work and investigate space," said Michael Gazarik, director of the program at NASA Headquarters in Washington. "We are confident these selected technologies, with their highly qualified research teams, will enable great new opportunities for the next chapter in NASA's innovation story."
　
The selected proposals take steps toward addressing critical technological barriers for advancing exploration and science missions, while also lowering the cost of other government and commercial space activities. Projects were selected through independent review of technical merit, alignment with NASA's Space Technology Roadmap priorities and the technology objectives identified by the National Research Council in its review of these roadmaps.
　
Awards range from $125,000 to $1.8 million, with a total NASA investment of approximately $6 million through 2015. NASA's Game Changing Development Program, located at the agency's Langley Research Center in Hampton, Va., is responsible for the management of these awards.

STAR FLASH

What caused this outburst of V838 Mon? For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before -- supernovas and novas expel matter out into space. Although the V838 Mon flash appears to expel material into space, what is seen in the above image from the Hubble Space Telescope is actually an outwardly moving light echo of the bright flash. In a light echo, light from the flash is reflected by successively more distant rings in the complex array of ambient interstellar dust that already surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of the unicorn (Monoceros), while the light echo above spans about six light years in diameter. Image Credit: NASA, ESA

THE SPIDERWEB GALAXY

Looking like a spider's web swirled into a spiral, Galaxy IC 342 presents its delicate pattern of dust in this image from NASA's Spitzer Space Telescope. Seen in infrared light, faint starlight gives way to the glowing bright patterns of dust found throughout the galaxy's disk. At a distance of about 10 million light-years, IC 342 is relatively close by galactic standards, however our vantage point places it directly behind the disk of our own Milky Way. The intervening dust makes it difficult to see in visible light, but infrared light penetrates this veil easily. IC 342 belongs to the same group as its even more obscured galactic neighbor, Maffei 2. IC 342 is nearly face-on to our view, giving a clear, top-down view of the structure of its disk. It has a low surface brightness compared to other spirals, indicating a lower density of stars (seen here as a blue haze). Its dust structures show up much more vividly (red). Blue dots are stars closer to us, in our own Milky Way. New stars are forming in the disk at a healthy rate. The very center glows especially brightly in the infrared, highlighting an enormous burst of star formation occurring in this tiny region. To either side of the center, a small bar of dust and gas is helping to fuel this central star formation. Data from Spitzer's infrared array camera are shown in blue (3.6 microns), green (4.5 microns) and red (5.8 and 8.0 microns). Image Credit: NASA/JPL-Caltech

JUMPING TO WARP SPEED

This cockpit view of a hypothetical spacecraft traveling at eight-tenths the speed of light shows the visual distortions that would be experienced at such high speeds. The star field is actually being wrapped toward the front of the craft in addition to being significantly blue-shifted.
