NASA RELEASES CALL FOR PHASE II VISIONARY ADVANCED CONCEPTS

FROM: NASA
WASHINGTON -- The NASA Innovative Advanced Concepts (NIAC) Program is
seeking proposals to continue promising studies for which it has
supported the first phase. These cutting-edge concepts have the
potential to transform future exploration missions, enable new
capabilities, or significantly alter current approaches to launching,
building, and operating aerospace systems.

"These transformative concepts have the potential to mature into the
new capabilities NASA needs for the challenging space missions in its
future," said Michael Gazarik, director of NASA's Space Technology
Program at NASA Headquarters in Washington.

NIAC projects are chosen based on their character as innovative and
visionary, technically substantiated, and very early in development
-- 10 years or more from use in a mission. NIAC's current diverse
portfolio represents multiple technology areas, including power,
propulsion, structures, and avionics.

"We are thrilled to be launching Phase II, so the 2012 NIAC portfolio
can feature the most exciting combination of new ideas and continued
development," said Jay Falker, NIAC program executive at NASA
Headquarters.

The call for proposals follows last summer's inaugural selection of
Phase I concepts, which are now under study. NIAC will be accepting
proposals of no more than 20 pages until June 6.

NASA expects to fund between five and nine Phase II studies this year.
The number of awards will depend on the strength of proposals and
availability of appropriated funds. Awardees will receive up to
$500,000 over two years to further analyze and develop their
innovative concepts and help create new avenues for future NASA
missions.

Selection announcements are expected in August. This limited
solicitation is only for continuing NIAC Phase I concepts. Phase II
proposals are eligible based on any current Phase I studies, or any
prior Phase I studies from the original NASA Institute for Advanced
Concepts that did not complete Phase II.

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.
