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.

NASA MISSION WANTS AMATEUR ASTRONOMERS TO TARGET ASTEROIDS
WASHINGTON -- A new NASA outreach project will enlist the help of
amateur astronomers to discover near-Earth objects (NEOs) and study
their characteristics. NEOs are asteroids with orbits that
occasionally bring them close to the Earth.
Starting today, a new citizen science project called "Target
Asteroids!" will support NASA's Origins Spectral Interpretation
Resource Identification Security - Regolith Explorer (OSIRIS-REx)
mission objectives to improve basic scientific understanding of NEOs.
OSIRIS-REx is scheduled for launch in 2016 and will study material
from an asteroid.
Amateur astronomers will help better characterize the population of
NEOs, including their position, motion, rotation and changes in the
intensity of light they emit. Professional astronomers will use this
information to refine theoretical models of asteroids, improving
their understanding about asteroids similar to the one OSIRIS-Rex
will encounter in 2019, designated 1999 RQ36.
OSIRIS-REx will map the asteroid's global properties, measure
non-gravitational forces and provide observations that can be
compared with data obtained by telescope observations from Earth. In
2023, OSIRIS-REx will return back to Earth at least 2.11 ounces (60
grams) of surface material from the asteroid.
Target Asteroids! data will be useful for comparisons with actual
mission data. The project team plans to expand participants in 2014
to students and teachers.
"Although few amateur astronomers have the capability to observe 1999
RQ36 itself, they do have the capability to observe other targets,"
said Jason Dworkin, OSIRIS-REx project scientist at NASA's Goddard
Space Flight Center in Greenbelt, Md.
Previous observations indicate 1999 RQ36 is made of primitive
materials. OSIRIS-REx will supply a wealth of information about the
asteroid's composition and structure. Data also will provide new
insights into the nature of the early solar system and its evolution,
orbits of NEOs and their impact risks, and the building blocks that
led to life on Earth.
Amateur astronomers long have provided NEO tracking observations in
support of NASA's NEO Observation Program. A better understanding of
NEOs is a critically important precursor in the selection and
targeting of future asteroid missions.
"For well over 10 years, amateurs have been important contributors in
the refinement of orbits for newly discovered near-Earth objects,"
said Edward Beshore, deputy principal investigator for the OSIRIS-REx
mission at the University of Arizona in Tucson.
NASA's Goddard Space Flight Center in Greenbelt, Md., will provide
overall mission management, systems engineering and safety and
mission assurance for OSIRIS-REx. Dante Lauretta is the mission's
principal investigator at the University of Arizona. Lockheed Martin
Space Systems in Denver will build the spacecraft. OSIRIS-REx is the
third mission in NASA's New Frontiers Program. NASA's Marshall Space
Flight Center in Huntsville, Ala., manages New Frontiers for the
agency's Science Mission Directorate in Washington.

TEACHING A SPACESHIP HOW TO FLY
A test model of the Orion spacecraft with its parachutes was tested the skies high above the U.S. Army’s Proving Grounds in Yuma, Ariz. on Feb. 29, 2012. This particular drop test examined the wake -- or the disturbance of the air flow behind Orion -- that is caused by the spacecraft. The U.S. Space Launch System, or SLS, will provide an entirely new capability for human exploration beyond Earth orbit and the Orion capsule is a major part of this program. The Orion spacecraft will replace the space shuttle as NASA's vehicle for human space exploration and is designed to accommodate four to six astronauts traveling into space. It also will supplement commercial and international partner transportation services to the International Space Station. Designed to be flexible for crew or cargo missions, SLS will continue America's journey of discovery from the unique vantage point of space. Image Credit: NASA

NASA, LIBRARY OF CONGRESS SELECT FIRST ASTROBIOLOGY CHAIR
FROM: NASA
WASHINGTON -- NASA and the Library of Congress have announced the
selection of David H. Grinspoon to be the first Baruch S. Blumberg
NASA-Library of Congress Chair in Astrobiology.
The chair, selected through an international competition, is named for
the late Nobel Laureate and founding director of the NASA
Astrobiology Institute, Baruch "Barry" Blumberg. Applications are
solicited by the Library of Congress and reviewed by a panel jointly
established by the Library and NASA. The prestigious position was
created in November 2011.
Grinspoon will be in residence for a year beginning November 2012 at
the library's scholarly research organization, the Kluge Center, in
Washington. He is the curator of astrobiology in the Department of
Space Sciences at the Denver Museum of Nature and Science. Grinspoon
is a well-known researcher in planetary science and the author of the
award-winning book "Lonely Planets: The Natural Philosophy of Alien
Life."
"Grinspoon's background as an astrobiology researcher, writer and
communicator of science makes him an ideal choice," said Carl
Pilcher, director of the Astrobiology Institute at NASA's Ames
Research Center at Moffett Field, Calif. "This is certainly the start
of what will become a great tradition of astrobiology chairs at the
library."
Astrobiology is the study of the origins, evolution, distribution and
future of life in the universe. It addresses three fundamental
questions: How did life begin and evolve? Is there life elsewhere?
What is the future of life on Earth and beyond? The institute's
mission is to promote interdisciplinary research in astrobiology,
train the next generation of astrobiologists and provide scientific
and technical leadership for NASA space missions.
"Grinspoon is uniquely positioned to introduce the Library's unique
multidisciplinary collections on the emerging subject to a wide and
diverse public," said Librarian of Congress James H. Billington.
At the library, Blumberg was a founding member of the Scholar's
Council, a 12-member group of distinguished scholars who advise the
Librarian of Congress on matters of scholarship.
Blumberg was awarded the 1976 Nobel Prize in physiology or medicine
for discovery of the Hepatitis B virus and development of a vaccine
to prevent Hepatitis B infection. He was the founding director of the
NASA Astrobiology Institute, serving from 1999 to 2002.
Grinspoon will examine choices facing humanity as we enter the
Anthropocene Era, the epoch when human activities are becoming a
defining characteristic of the physical nature and functioning of
Earth. His research will include studies of the role of planetary
exploration in fostering scientific and public understanding of
climate change and the power of astrobiology as a model of
interdisciplinary research and communication.
