NASA LOOKING FOR WORKSHOP PARTICIPANTS TO LEARN HOW TO LAUNCH EXPERIMENT INTO SPACE


The following excerpt is from the NASA website:

WASHINGTON -- University faculty and students are invited to join a
weeklong workshop June 16-21 to learn how to build and launch a
scientific experiment to space. Registration is open through May 1.

RockOn! 2012 will be held at NASA's Wallops Flight Facility on the
Eastern Shore of Virginia. The annual workshop is held in partnership
with the Colorado and Virginia Space Grant Consortia.

"This workshop provides an opportunity for participants to learn how
to build an experiment for space flight," said Phil Eberspeaker,
chief of the sounding rocket program office at Wallops. "The hope is
this experience will encourage them to participate in more ambitious
payload programs, including someday building instruments for orbital
spacecraft and beyond."

During the program, participants will work together to build
experiment payloads for a NASA Terrier-Orion sounding rocket
predicted to fly to an altitude of 73 miles. The flight will take
place June 21, the last day of the workshop, weather permitting.

"During the week, the participants will gain an understanding of what
it takes to build a basic scientific payload," said Chris Koehler,
director of the Colorado Space Grant Consortium. "Through hands-on
learning, they will learn how to develop circuit boards, program
flight code and work together as a cohesive team."

Since the annual workshop began in 2008, 150 students and instructors
have participated. It has been a successful program, with all
experiments completed on time, launched and recovered. In addition,
48 of the 50 payloads have worked as intended.

U.S. STATE DEPARTMENT SPEECH REGARDING UTILIZATION OF SPACE


The following excerpt is from the U.S. State Department website:

Space Sustainability Through International Cooperation
Remarks Frank A. Rose
Deputy Assistant Secretary, Bureau of Arms Control, Verification and Compliance International Symposium on Sustainable Space Development and Utilization for Humankind: Orbital Space Debris -- Challenges and Opportunities
Tokyo, Japan
February 29, 2012

Thank you for your kind introduction. It is my pleasure to be back in Tokyo today for this Symposium on “Sustainable Space Development and Utilization for Humankind” with a particular emphasis on orbital space debris. I would like to thank the Japan Space Forum for the invitation to speak at this symposium. I’d also like to thank the Strategic Headquarters for Space Policy of Cabinet Secretariat, the Ministry of Foreign Affairs, Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Economy, Trade and Industry, and the Society of Japanese Aerospace Companies for their support in organizing this timely event.

This symposium comes almost one year following the earthquake and resulting tsunami. I would like to offer my deepest condolences for the great tragedy that Japan faced and is still recovering from. The cooperation between the U.S. and Japan during this tragedy reaffirmed the significance of the alliance between our two countries. In addition, Japan’s use of space assets during the disaster sheds light on the vital importance of space assets for disaster monitoring and mitigation. Remote sensing and disaster monitoring satellites enabled Japanese authorities and aid workers to see the affected areas to assist their response. Additionally, since many ground based communication networks were destroyed in the disaster, satellite communications proved to be an essential alternative in providing secure, reliable communication between the search and rescue operators, ground forces, and senior officials. Finally, positioning, navigation, and timing services, such as those derived from the U.S. Global Positioning System, aided in the coordination of disaster relief and search and rescue of disaster victims.

The use of space capabilities during this disaster is one example of how the world is becoming increasingly inter-connected through, and increasingly dependent on, space systems. As a result of the critical benefits it offers, the United States considers the sustainability, stability, and use of space vital to its national interests.

There are a number of challenges that have emerged as a result of increased space activity by an unprecedented number of spacefaring nations. As a result, the space activities that have provided us with a multitude of benefits have also created a space environment littered with space debris. Threats to the space environment have also increased as more nations and non-state actors develop and deploy counter-space systems. Today space systems and their supporting infrastructure face a range of man-made threats that may deny, degrade, deceive, disrupt, or destroy assets.

The increasingly congested and contested nature of the space environment offers critical challenges, which threatens the long-term sustainability of our space activities, and will continue to present challenges in the decades to come. But this symposium intends not only to discuss challenges, but also opportunities, and in particular, opportunities for international cooperation. Such opportunities include cooperation to mitigate orbital debris, share space situational awareness information, improve information sharing for collision avoidance, and develop transparency and confidence building measures. Today, I will discuss how collaboration in each of these areas has the potential of enhancing the long term sustainability, stability, safety, and security of the space environment.

Cooperation to Mitigate Orbital Debris
The key issue that we are here to discuss today is the growing presence of debris in space. After 50 years of space exploration and utilization, a comedian might even say there’s not as much space up there as there used to be! But the problem of potentially hazardous debris is not a joke, but rather an increasingly greater and greater danger. As my colleagues from the Department of Defense will discuss later, there are approximately 22,000 pieces of large debris (>~10 cm) in various Earth orbits. Some of this debris is simply “dead” satellites or spent booster upper stages still orbiting. Another type of debris results from accidents or mishaps, such as the 2009 Cosmos-Iridium collision. Other accidents that have occurred are when objects slipped the grasp of our astronauts including a glove, cameras, a wrench, pliers, a tool bag, and even a toothbrush. Still another type of debris results from intentionally destructive events, such as China’s test in space of an anti-satellite weapon in 2007 that intercepted its own weather satellite, thus generating long-lived debris, some of which will not re-enter Earth’s atmosphere for over 100 years.

Experts warn that the quantity and density of all of these types of debris significantly increases the odds of future dangerous and damaging collisions. This debris also poses a direct threat to the International Space Station. In fact, less than two months ago, the United States and Russia orchestrated a debris avoidance maneuver of the International Space Station in order to avoid a series of collision threats posed by a fragment of debris created by China’s 2007 anti-satellite weapons test.

To address the growing problem of orbital debris, the United States has expanded its engagement within the United Nations and with other governments and non-governmental organizations. We are continuing to lead the development and adoption of international standards to minimize debris, building upon the foundation of the U.N. Space Debris Mitigation Guidelines. I’ll also note that the U.S. guidelines on debris mitigation are even stricter than those that were established by the Inter-Agency Space Debris Coordination Committee and then adopted by the Committee on the Peaceful Uses of Outer Space and endorsed by the United Nations. Space debris is also a topic currently being discussed within the multi-year study of “long-term sustainability” within the Scientific and Technical Subcommittee of the U.N. Committee on the Peaceful Uses of Outer Space, or COPUOS, which I’ll discuss in greater detail later in my remarks.

Cooperation in Space Situational Awareness
International cooperation is also necessary to ensure that we have robust situational awareness of the space environment. No one nation has the resources or geography necessary to precisely track every space object. The U.S. National Space Policy implicitly recognizes this fact and thus directs us to collaborate with foreign governments, the private sector, and intergovernmental organizations to improve our space situational awareness – specifically, to improve our shared ability to rapidly detect, warn of, characterize, and attribute potential disturbances to space systems, whether natural or man-made.

An example of our efforts to cooperate in the area of space situational awareness is our collaboration with Europe as it develops its own space situational awareness, or SSA system. The U.S. State Department, in close collaboration with the U.S. Department of Defense, is currently engaged in technical exchanges with experts from the European Space Agency, European Union, and individual European Space Agency and European Union Member States to ensure interoperability between our two respective SSA systems. Looking ahead, we also see opportunities for cooperation on SSA with our allies and partners in the Asia-Pacific, especially Japan.

Cooperation to Prevent Satellite Collisions
International cooperation is also essential to enable satellite owners and operators to have the information necessary to prevent collisions in the future. As a result, we are seeking to improve our ability to share information with other space-faring nations as well as with our industry partners. Such cooperation enables us to improve our space object databases as well as pursue common international data standards and data integrity measures.

As my colleagues in the Department of Defense will explain, the United States provides notifications to other governments and commercial satellite operators of potentially hazardous conjunctions between orbiting objects. The State Department continues to be extremely supportive of U.S. Strategic Command’s efforts to establish two-way information exchanges with foreign satellite operators and to facilitate the urgent transmission of notifications of potential space hazards.

The United States is constantly seeking to improve its ability to share information with other space-faring nations as well as with our commercial sector partners. For example, the Department of State is currently reaching out to all space-faring nations to ensure that the Joint Space Operations Center, or JSpOC, has current contact information for both government and private sector satellite operations centers.

Cooperation in Developing TCBMs
Another key opportunity to cooperate to enhance the long term sustainability of the space environment is through the development of near-term, voluntary, and pragmatic space transparency and confidence building measures, or TCBMs for short. TCBMs are means by which governments can address challenges and share information with the aim of creating mutual understanding and reducing tensions. TCBMs, also have the potential of enhancing our knowledge of the space environment, by addressing important areas such as orbital debris, space situational awareness, and collision avoidance, as well as undertake activities that will help to increase familiarity and trust and encourage openness among space actors. The United States, as guided by President Obama’s National Space Policy, will work with other space actors to pursue TCBMs to encourage responsible actions in, and the peaceful use of, space.

An International Code of Conduct for Outer Space Activities
An example of a TCBM to ensure sustainability and security in space could be the adoption of “best practice” guidelines or a “code of conduct.” As many of you are aware, on January 17, 2012, the United States announced that it had decided to join with the European Union and other spacefaring nations to develop an International Code of Conduct for Outer Space Activities. In her statement announcing the decision, Secretary Clinton said, “The long-term sustainability of our space environment is at serious risk from space debris and irresponsible actors. […] Unless the international community addresses these challenges, the environment around our planet will become increasingly hazardous to human spaceflight and satellite systems, which would create damaging consequences for all of us.” We were pleased that Japan, Australia, and other countries have also stated their support for the development of a space Code of Conduct.

The United States views the European Union’s draft Code of Conduct as a good foundation for developing a non-legally binding International Code of Conduct focused on the use of voluntary and pragmatic TCBMs to help prevent mishaps, misperceptions, and mistrust in space. As more countries field space capabilities, it is in all of our interests that they act responsibly and that the safety and sustainability of space is protected. An International Code of Conduct, if adopted, would establish a political commitment not to conduct debris-generating events and would increase the transparency of operations in space to avoid the danger of collisions.

I want to stress that the Obama Administration is committed to ensuring that an International Code enhances national security and maintains the United States’ inherent right of individual and collective self-defense, a fundamental part of international law. That said, we would encourage spacefaring nations to consider playing an active role as we prepare to multilaterally discuss a Code of Conduct. All spacefaring nations, both established and emerging, will have the opportunity to participate actively in multilateral meetings of experts in 2012 that the European Union will schedule. We look forward to engaging with you on this initiative in the months to come.

Group of Government Experts on Outer Space TCBMs
An additional opportunity to cooperate with the international community to enhance the long-term sustainability of our space activities is through the Group of Government Experts (or GGE) on Outer Space TCBMs, established by UN General Assembly Resolution 65/68. It is our hope that the Group of Governmental Experts will serve as a constructive mechanism to identify and examine the range of voluntary and pragmatic TCBMs in space that have the potential to mitigate the dangers and risks in an increasing contested and congested space environment. For example, TCBM proposals could include measures aimed at enhancing the transparency derived from exchanging national security space policies, strategies, activities and experiments or notifications regarding environmental or unintentional hazards to spaceflight safety. International consultations to prevent incidents in outer space and to prevent or minimize the risks of potentially harmful interference could also be a helpful TCBM to consider.

Over the past five years, there have been various U.N. General Assembly resolutions inviting all U.N. Member States to submit to the Secretary-General concrete proposals on international TCBMs. In July 2010, the U.N. Secretary-General compiled a report including all the contributions received from almost 25 different countries. It is our assumption that this report will be the starting point for the work of this GGE. While the United States may not be able to accept all TCBMs listed in this report, we can accept those that are voluntary, pragmatic, work to solve concrete problems, and enhance the stability and security of the space environment for all spacefaring nations. We look forward to working with our international colleagues in a GGE that serves as a constructive mechanism to examine voluntary and pragmatic TCBMs that enhance stability and safety, and promote responsible operations in space.

UN Committee on the Peaceful Uses of Outer Space
Finally, in addition to “top-down” cooperative initiatives, the United States believes there is also great value in efforts to adopt space TCBMs through “bottom-up” initiatives developed by government and private sector satellite operators. Therefore, the United States is taking an active role in the Working Group of the Scientific and Technical Subcommittee of UNCOPUOS on long-term sustainability.

This Working Group on the Long-Term Sustainability of Space Activities will be a key forum for the international development of “best practices guidelines” for space activities. We believe that many of the best practice guidelines addressed by this working group are integral to our efforts to pursue TCBMs that enhance stability and security in space. In fact, the United States is serving as the co-Chair of the Expert Group on Space Debris, Space Operations, and Space Situational Awareness, demonstrating our commitment to making progress to enhance spaceflight safety and to preserving the use of space for the long-term.

The United States is playing an active role in all of the expert groups, including the expert group led by Japan on space weather. Space weather is of particular concern to the long term sustainability of our space activities. Besides the direct hazard it poses to earth-orbiting satellites, space weather events greatly complicates SSA and collision prevention. We are pleased at the progress of these expert groups and believe the guidelines they develop will help to reduce risks to all space systems.

Sustaining Space for Future Generations
As you can see, there are a variety of international fora currently looking at how the international community can cooperate to enhance the long-term sustainability of the space environment. Given the broad range of discussion focusing on space, I believe 2012 will be a defining year for space security, and the work we all will do in responding to the challenges of, and the threats to, the space environment. In fact, we believe that this is such a pivotal period, that the United States has introduced discussions on the long-term sustainability, stability, safety, and security of the space environment in the Group of Eight or G8. We believe that the G8, which contains a number of major spacefaring nations, could play a useful role in this field and will draw further attention to the importance of ensuring space for future generations.

I would like to conclude by emphasizing that now it is our opportunity to cooperate with established and emerging members of the space-faring community and with the private sector to work together to preserve the space environment for the benefit of all nations and future generations. The support of governments in the Asia-Pacific region is critical to our success. However, if we do not take action, the congestion in space will only increase, and we will lose valuable time in solving the problem. We cannot let the wide range of opportunities we have to cooperate now to sustain our use of space pass us by.
Thank you very much.”

NASA NAMES ORLANDO FIGUEROA TO LEAD NEW MARS PROGRAM PLANNING GROUP


The following excerpt is from the NASA website:

“WASHINGTON -- NASA' s associate administrator for the Science Mission
Directorate, John Grunsfeld, has named former veteran NASA program
manager Orlando Figueroa to lead a newly established Mars Program
Planning Group (MPPG) tasked to reformulate the agency's Mars
Exploration Program. Figueroa's first assignment is to develop a
draft framework for review by March 15.

Grunsfeld made the announcement at an annual gathering of Mars
scientists and engineers in Dulles, Va. Figueroa, a consultant with
more than 30 years of aerospace experience, will lead the scientific
and technical team to develop an integrated strategy for NASA's Mars
Exploration Program in light of current funding constraints. The
team's initial focus will be on a possible 2018-2020 robotic mission.
The program's official framework will be developed in consultation
with the science community and international partners and is expected
to be released for full review as early as this summer.

"The team will develop a plan that advances the priorities in the
National Research Council's Decadal Survey, which puts sample return
as the top scientific goal, and leverages NASA's research in enabling
technology," Grunsfeld said. "Our investments in the new Mars program
will incorporate elements of advanced research and technologies in
support of a logical sequence of missions to answer fundamental
scientific questions and ultimately support the goal of sending
people to Mars."

The MPPG will report to Grunsfeld, a physicist and five-time flown
space shuttle astronaut. Grunsfeld is chairing the overall,
agency-wide reformulation strategy along with William Gerstenmaier,
associate administrator for the human exploration and operations
directorate, NASA Chief Scientist Waleed Abdalati and NASA Chief
Technologist Mason Peck. The MPPG will ensure that America maintains
the critical technical skills developed over decades needed to
achieve the highest priority science and exploration objectives.

NASA has a recognized track record of successful Mars missions. The
rover Opportunity, which landed on Mars in 2004, is still operating
despite an official mission timeline of 90 days. There are also two
NASA satellites orbiting the Red Planet; the Mars Reconnaissance
Orbiter and Mars Odyssey. The duo continue to return unprecedented
science data and images. This August, NASA will land the Mars Science
Laboratory, "Curiosity," on the planet's surface. This roving science
laboratory will assess whether Mars was or is today an environment
able to support life. In 2013, NASA will launch the Mars Atmosphere
and Volatile Evolution orbiter, the first mission devoted to
understanding the Martian upper atmosphere.

NASA will continue to gather critical information to help scientists
understand the Red Planet. These data will be used in future years to
meet President Obama's challenge to send humans to Mars in the
mid-2030s.

"We'll look at all of the assets NASA is developing to reach, explore
and study Mars, as well as spacecraft at or on its way to Mars,"
Figueroa said.

NASA already has been developing technology that will improve
precision in landing, the ability to conduct scientific analysis
remotely, handle and collect samples, and transmit larger volumes of
data back to Earth.

"The science and engineering communities have worked continuously over
a decade to define our knowledge gaps for Mars exploration, so we
have a solid starting point," Grunsfeld said.

Mars exploration is a top priority for NASA. America's investment in
exploring Mars during the past decade totals $6.1 billion. NASA
Administrator Charlie Bolden directed Grunsfeld to lead the
agency-wide team in order to optimize a coordinated strategy of Mars
exploration and continue America's leadership role in the exploration
of the Red Planet within available future budgets.”

RUSSIAN CONSTRUCTION CREW WORK IN SPACE




"This image of Russian cosmonauts Oleg Kononenko and Anton Shkaplerov, both Expedition 30 flight engineers, was taken during a spacewalk on Thursday, Feb. 16, 2012. During the six-hour, 15-minute spacewalk, Kononenko and Shkaplerov moved the Strela-1 crane from the Pirs Docking Compartment in preparation for replacing it in 2012 with a new laboratory and docking module. The duo used another boom, the Strela-2, to move the hand-operated crane to the Poisk module for future assembly and maintenance work. Both telescoping booms extend like fishing rods and are used to move massive components outside the station. On the exterior of the Poisk Mini-Research Module 2, they also installed the Vinoslivost Materials Sample Experiment, which will investigate the influence of space on the mechanical properties of the materials. The spacewalkers also collected a test sample from underneath the insulation on the Zvezda Service Module to search for any signs of living organisms. Both spacewalkers wore Russian Orlan spacesuits bearing blue stripes and equipped with NASA helmet cameras. Image Credit: NASA"

STAR READIES FOR SPECTACULAR SUPERNOVA




“NASA's Hubble Telescope captured an image of Eta Carinae. This image consists of ultraviolet and visible light images from the High Resolution Channel of Hubble's Advanced Camera for Surveys. The field of view is approximately 30 arcseconds across. The larger of the two stars in the Eta Carinae system is a huge and unstable star that is nearing the end of its life, and the event that the 19th century astronomers observed was a stellar near-death experience. Scientists call these outbursts supernova impostor events, because they appear similar to supernovae but stop just short of destroying their star. Although 19th century astronomers did not have telescopes powerful enough to see the 1843 outburst in detail, its effects can be studied today. The huge clouds of matter thrown out a century and a half ago, known as the Homunculus Nebula, have been a regular target for Hubble since its launch in 1990. This image, taken with the Advanced Camera for Surveys High Resolution Channel, is the most detailed yet, and shows how the material from the star was not thrown out in a uniform manner, but forms a huge dumbbell shape. Eta Carinae is one of the closest stars to Earth that is likely to explode in a supernova in the relatively near future (though in astronomical timescales the "near future" could still be a million years away). When it does, expect an impressive view from Earth, far brighter still than its last outburst: SN 2006gy, the brightest supernova ever observed, came from a star of the same type, though from a galaxy over 200 million light-years away.

NASA ANNOUNCES SOLID BUCKYBALLS FOUND IN SPACE


The following excerpt is from the NASA website:

“NASA'S SPITZER FINDS SOLID BUCKYBALLS IN SPACE
WASHINGTON -- Astronomers using data from NASA's Spitzer Space
Telescope have, for the first time, discovered buckyballs in a solid
form in space. Prior to this discovery, the microscopic carbon
spheres had been found only in gas form.

Formally named buckminsterfullerene, buckyballs are named after their
resemblance to the late architect Buckminster Fuller's geodesic
domes. They are made up of 60 carbon molecules arranged into a hollow
sphere, like a soccer ball. Their unusual structure makes them ideal
candidates for electrical and chemical applications on Earth,
including superconducting materials, medicines, water purification
and armor.

In the latest discovery, scientists using Spitzer detected tiny specks
of matter, or particles, consisting of stacked buckyballs. They found
them around a pair of stars called "XX Ophiuchi," 6,500 light-years
from Earth.

"These buckyballs are stacked together to form a solid, like oranges
in a crate," said Nye Evans of Keele University in England, lead
author of a paper appearing in the Monthly Notices of the Royal
Astronomical Society. "The particles we detected are miniscule, far
smaller than the width of a hair, but each one would contain stacks
of millions of buckyballs."

Buckyballs were detected definitively in space for the first time by
Spitzer in 2010. Spitzer later identified the molecules in a host of
different cosmic environments. It even found them in staggering
quantities, the equivalent in mass to 15 Earth moons, in a nearby
galaxy called the Small Magellanic Cloud.

In all of those cases, the molecules were in the form of gas. The
recent discovery of buckyballs particles means that large quantities
of these molecules must be present in some stellar environments in
order to link up and form solid particles. The research team was able
to identify the solid form of buckyballs in the Spitzer data because
they emit light in a unique way that differs from the gaseous form.

"This exciting result suggests that buckyballs are even more
widespread in space than the earlier Spitzer results showed," said
Mike Werner, project scientist for Spitzer at NASA's Jet Propulsion
Laboratory in Pasadena, Calif. "They may be an important form of
carbon, an essential building block for life, throughout the cosmos."


Buckyballs have been found on Earth in various forms. They form as a
gas from burning candles and exist as solids in certain types of
rock, such as the mineral shungite found in Russia, and fulgurite, a
glassy rock from Colorado that forms when lightning strikes the
ground. In a test tube, the solids take on the form of dark, brown
"goo."

"The window Spitzer provides into the infrared universe has revealed
beautiful structure on a cosmic scale," said Bill Danchi, Spitzer
program scientist at NASA Headquarters in Washington. "In yet another
surprise discovery from the mission, we're lucky enough to see
elegant structure at one of the smallest scales, teaching us about
the internal architecture of existence."

NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., manages
the Spitzer Space Telescope mission for NASA's Science Mission
Directorate in Washington. Science operations are conducted at the
Spitzer Science Center at the California Institute of Technology in
Pasadena. Caltech manages JPL for NASA.”

MASSIVE BLACK HOLE SUCKS IN GAS FROM ANOTHER STAR




The above picture and following excerpt is from the NASA website:

This artist's impression shows a binary system containing a stellar-mass black hole called IGR J17091-3624, or IGR J17091 for short. The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk. New observations with NASA's Chandra X-ray Observatory clocked the fastest wind ever seen blowing off a disk around this stellar-mass black hole. Stellar-mass black holes are born when extremely massive stars collapse and typically weigh between five and 10 times the mass of the Sun. The record-breaking wind is moving about twenty million miles per hour, or about three percent the speed of light. This is nearly ten times faster than had ever been seen from a stellar-mass black hole, and matches some of the fastest winds generated by supermassive black holes, objects millions or billions of times more massive. Another unanticipated finding is that the wind, which comes from a disk of gas surrounding the black hole, may be carrying away much more material than the black hole is capturing. The high speed for the wind was estimated from a spectrum made by Chandra in 2011. A spectrum shows how intense the X-rays are at different energies. Ions emit and absorb distinct features in spectra, which allow scientists to monitor them and their behavior. A Chandra spectrum of iron ions made two months earlier showed no evidence of the high-speed wind, meaning the wind likely turns on and off over time. Image Credit: NASA/CXC/M.Weiss

OLDEST DOCUMENTED SUPERNOVA

This image combines data from four space telescopes to create a multi-wavelength view of all that remains of RCW 86, the oldest documented example of a supernova. Chinese astronomers witnessed the event in 185 A.D., documenting a mysterious "guest star" that remained in the sky for eight months. X-ray images from NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton Observatory were combined to form the blue and green colors in the image. The X-rays show the interstellar gas that has been heated to millions of degrees by the passage of the shock wave from the supernova. Infrared data from NASA's Spitzer Space Telescope and WISE, Wide-Field Infrared Survey Explorer, shown in yellow and red, reveal dust radiating at a temperature of several hundred degrees below zero, warm by comparison to normal dust in our Milky Way galaxy. By studying the X-ray and infrared data, astronomers were able to determine that the cause of the explosion was a Type Ia supernova, in which an otherwise-stable white dwarf, or dead star, was pushed beyond the brink of stability when a companion star dumped material onto it. Furthermore, scientists used the data to solve another mystery surrounding the remnant -- how it got to be so large in such a short amount of time. By blowing away wind prior to exploding, the white dwarf was able to clear out a huge "cavity," a region of very low-density surrounding the system. The explosion into this cavity was able to expand much faster than it otherwise would have. This is the first time that this type of cavity has been seen around a white dwarf system prior to explosion. Scientists say the results may have significant implications for theories of white-dwarf binary systems and Type Ia supernovae. RCW 86 is approximately 8,000 light-years away. At about 85 light-years in diameter, it occupies a region of the sky in the southern constellation of Circinus that is slightly larger than the full moon. This image was compiled in October 2011.

NASA TO DELIVER CENTRIFUGE TO INVESTIGATE PLANT AND ANIMAL CELLS


The following excerpt is from the NASA website: 

"HOUSTON -- NASA, Astrium Space Transportation and NanoRacks LLC are 
teaming up to expand the research capability of the International 
Space Station through delivery of a small commercial centrifuge 
facility that will conduct molecular and cellular investigations on 
plant and animal tissue. 

The centrifuge enhances NanoRacks' existing suite of lab equipment 
aboard the space station, which includes microscopes and a plate 
reader used to detect biological, chemical or physical activity in 
samples. 

Astrium Space Transportation handed over the research centrifuge to 
NanoRacks LL, during a ceremony Tuesday, Feb. 14 in Houston. Astrium 
North America adapted the centrifuge -- originally built by Kayser 
Italia for use on space shuttle missions -- for use in the station's 
NanoRacks Platform-3. The commercial research team funded the 
centrifuge. 

NASA will deliver the centrifuge as part of its responsibility to 
provide transportation for U.S. National Laboratory research and 
facilities to the space station. 

Under its partnership with Astrium, NanoRacks will add the centrifuge 
to the two racks of laboratory support equipment already on the 
station. The centrifuge is sized to fit the standard NanoRacks 
architecture, which can fly on any launch vehicle. 

"This is an important step in the expansion of National Lab facilities 
aboard the space station," said Marybeth Edeen, U.S. National 
Laboratory manager at NASA's Johnson Space Center. "Having companies 
develop research and facilities for the National Lab with their own 
funding demonstrates the beginnings of the commercial space 
marketplace that the National Lab was created to serve." 

The platform and centrifuge were produced in a short time at low cost. 
Both NanoRacks and Astrium expect announcements in the near future 
about more joint projects. 

NASA has manifested the NanoRacks-3 platform and the Astrium 
centrifuge on a Russian Progress cargo ship scheduled for launch in 
summer 2012 under its cargo agreements with the Russian Federal Space 
Agency."

NASA'S $17.7 BILLION BUDGET WILL SUPPORT "AMBITIOUS" SPACE EXPLORATION PROGRAM

The following excerpt is from the NASA website: WASHINGTON -- NASA announced Monday a $17.7 billion budget request for fiscal year 2013 supporting an ambitious program of space exploration that will build on new technologies and proven capabilities to expand America's reach into the solar system. Despite a constrained fiscal environment, the NASA FY13 budget continues to implement the space science and exploration program agreed to by President Obama and a bipartisan majority in Congress, laying the foundation for ground-breaking discoveries here on Earth and in deep space, including new destinations, such as an asteroid and Mars by 2035. "This budget in-sources jobs, creates capabilities here at home -- and strengthens our workforce, all while opening the next great chapter in American exploration," NASA Administrator Charles Bolden said. "And as we reach for new heights in space, we're creating new jobs right here on Earth, helping to support an economy that's built to last." The NASA budget includes $4 billion for space operations and $4 billion for exploration activities in the Human Exploration Operations mission directorate, including close-out of the Space Shuttle Program, and funding for the International Space Station, $4.9 billion for science, $669 million for space technology and $552 million for aeronautics research. "This budget puts us on course to explore farther into space than ever before, revealing the unknown and fueling the nation's economy for years to come," Deputy Administrator Lori Garver said. "We are committed to ensuring that our astronauts are once again launched from U.S. soil on American-made spacecraft, and this budget provides the funds to make this a reality." The budget supports NASA's continued work to develop the Space Launch System, a new heavy-lift rocket to carry astronauts to destinations such as an asteroid and Mars, and the Orion crew capsule in which they will travel. Included are resources for final preparation and manufacturing milestones for Orion's 2014 Exploration Flight Test 1 and preliminary design reviews of major Space Launch System elements. NASA has prioritized funding for its partnership with the commercial space industry to facilitate crew and cargo transport to the station. The $830 million for this work in the FY13 budget advances progress towards a vibrant space industry that will create well-paying, high-tech jobs to the U.S. economy, and reduce America's reliance on foreign systems. The budget also enhances use of the International Space Station to improve life on Earth and help make the next great leaps in scientific discovery and exploration. NASA's science budget supports a balanced portfolio of innovative science missions that will reach farther into our solar system, reveal unknown aspects of our universe, and provide critical data about our home planet. The agency will continue to develop and conduct critical tests on the James Webb Space Telescope leading to its planned launch in 2018. As the successor to Hubble Space Telescope, James Webb again will revolutionize our understanding of the universe. NASA also is developing an integrated strategy to ensure the next steps for the robotic Mars Exploration Program will support science as well as long-term human exploration goals. Space Technology work supported in the budget will drive advances in new high-payoff space technologies such as laser communications and zero-gravity propellant transfer, seeding innovation that will expand our capabilities in the skies and in space, supporting economic vitality, lowering the cost of other government and commercial space activities, and helping to create new jobs and expand opportunities for a skilled workforce. NASA supports its commitment to enhancing aviation safety and airspace efficiency, and reducing the environmental impact of aviation by helping to accelerate the nation's transition to the Next Generation Air Transportation System through investments in revolutionary concepts for air vehicles and air traffic management. "The 2013 budget moves us forward into tangible implementation of a sustainable and affordable exploration program," NASA's Chief Financial Officer Elizabeth Robinson said.

SPACE COMMUNICATIONS AND NAVIGATION TESTBED WILL BE SENT TO SPACE STATION

The following excerpt and photo are from the NASA website: "In this image from late 2010, software engineers worked in the background as Glenn Research Center technician, Joe Kerka, rotated the SCaN Testbed flight enclosure assembly. The Space Communications and Navigation, or SCaN Testbed will be launched on a Japanese H–IIB Transfer Vehicle and installed on the International Space Station and will provide an on-orbit, adaptable software-defined radio facility with corresponding ground and operational systems. This will permit mission operators to remotely change the functionality of radio communications and offer the flexibility to adapt to new science opportunities and recover from anomalies within the science payload or communication system. This effort is sponsored by the SCaN Program as part of the , CoNNeCT, or Communications, Navigation, and Networking reConfigurable Testbed Project led by Glenn Research Center. The Glenn Research Center will host a media event at 10:30 am on Friday, Feb/. 10, to showcase the SCsN Testbed before it is shipped to Japan. Image Credit: NASA/Quentin L. Schwinn."

NASA SEEKS PROPOSALS FOR SMALL SUBORBITAL PAYLOADS

The following excerpt is from the NASA website: “WASHINGTON -- NASA is seeking proposals for small technology payloads that could fly on future NASA-sponsored suborbital flights. These future flights will travel to the edge of space and back, testing the innovative new technologies before they're sent to work in the harsh environment of space. "NASA's Game Changing Development Program focuses on maturing advanced space technologies that may lead to entirely new approaches for the agency's future space missions while providing solutions to significant national needs and adding to our nation’s innovation economy," said Michael Gazarik, director of NASA's Space Technology Program at NASA Headquarters in Washington. "This solicitation offers an opportunity to develop potentially transformative technologies that take advantage of our Flight Opportunities Program platforms, which allow frequent and predictable commercial access to near-space, with easy recovery of intact payloads." NASA's Game Changing Opportunities research announcement seeks proposals for payloads, vehicle enhancements and onboard facilities for payload integration that will help the agency advance technology development in the areas of exploration, space operations and other innovative technology areas relevant to NASA's missions. Sponsored by NASA's Space Technology Program, the agency expects proposals from entrepreneurs, scientists, technologists, instrument builders, research managers, and vehicle builders and operators. "This call for proposals is a great opportunity to develop innovative technology development payloads for flight on commercial suborbital, reusable vehicles which have novel ideas and approaches have the potential to revolutionize future space missions," said Stephen Gaddis, Game Changing Development program manager at NASA's Langley Research Center in Hampton, Va. Special emphasis will be given to proposals that address basic and applied research as well as development for advanced technologies and the development of test articles and techniques for evaluating the articles. Following development, selected payloads will be made available to NASA's Flight Opportunities Program for pairing with appropriate suborbital reusable launch service provider flights. In August 2011, NASA selected seven U.S. companies that can provide flight services and platforms to test innovative technology payloads through the Flight Opportunities Program. Under this solicitation, the selected Flight Opportunities suborbital reusable launch vehicles could be modified to facilitate integration and payload engineering of future payloads in support of specific research needs.
