AN OLD SOL FLARES UP
The photo and excerpt are from the NASA website:
NASA's Solar Dynamics Observatory (SDO) captured this image of an M7.9 class flare on March 13, 2012 at 1:29 p.m. EDT. It is shown here in the 131 Angstrom wavelength, a wavelength particularly good for seeing solar flares and a wavelength that is typically colorized in teal. The flare peaked at 1:41 p.m. EDT. It was from the same active region, No. 1429, that produced flares and coronal mass ejections the entire week. The region has been moving across the face of the sun since March 2, and will soon rotate out of Earth view. A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and last from mere minutes to several hours. Scientists classify solar flares according to their x-ray brightness. There are 3 categories: X-, M- and C-class. X-class flares are the largest of these events. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Compared to X- and M-class, C-class flares are small with few noticeable consequences on Earth. Image Credit: NASA/SDO

STUDENTS OFFERED CHANCE TO DESIGN DEEP SPACE HABITAT
The following excerpt is from the NASA website:
HOUSTON -- NASA is offering college and university students a chance to help design a deep space habitat. The Exploration Habitat (X-Hab) Academic Innovation Challenge is accepting applications for the 2013 challenge, inviting students to design, manufacture, assemble and test systems for use on NASA's deep space habitat prototype. Past projects have included an inflatable loft for crew sleeping quarters, plant growth systems and sample handling tools. This year, students in multiple disciplines can choose projects from a variety of possibilities, including photovoltaic solar arrays, a workstation to support human-robotic collaboration or a telepresence and holodeck conceptual system. Students will work together on potential solutions to needs future astronauts might have living and working outside Earth. "Students will play a vital role in our critical early system planning and development," said Alvin Drew, a NASA astronaut and habitat systems project manager at the agency's Johnson Space Center in Houston. "Their designs could become the basis for the concepts and technologies that will make up the habitat we eventually send to space." The X-Hab Challenge is part of a continuing effort to engage and retain students in science, technology, engineering and mathematics, or STEM, and provide a real-world challenge exposing them to engineering and design processes. NASA will directly benefit from the development of innovative habitation-related concepts and technologies that could be applied to future missions. The challenge is run by the National Space Grant Foundation for the deep space habitat project team at Johnson, which is part of NASA's Advanced Exploration Systems Program. The goal of for the X-Hab Challenge is to help NASA inspire the STEM workforce of the future and the next generation of explorers. Winners will receive between $10,000 and $49,000 to produce functional products based on their designs. Proposals are due May 2, 2012, and awardees should expect to deliver their product to Johnson in May or June 2013.

SPACE ROBOTS
The following excerpt is from the NASA website:
WASHINGTON -- NASA's Robotic Refueling Mission (RRM) experiment aboard
the International Space Station has demonstrated remotely controlled
robots and specialized tools can perform precise satellite-servicing
tasks in space. The project marks a milestone in the use of the space
station as a technology test bed.
"We and our partners are making important technological
breakthroughs," NASA Administrator Charles Bolden said. "As we move
ahead toward reaching our exploration goals, we will realize even
more benefits from humans and robots working together in space."
The Canadian Space Agency's (CSA) robotic handyman, Dextre,
successfully completed the tasks March 7-9 on the space station's
external RRM module, designed to demonstrate the tools, technologies
and techniques needed to robotically refuel and repair satellites.
"The Hubble servicing missions taught us the importance and value of
getting innovative, cutting-edge technologies to orbit quickly to
deliver great results," said Frank Cepollina, a veteran leader of
five Hubble Space Telescope servicing missions and associate director
of the Satellite Servicing Capabilities Office (SSCO) at NASA's
Goddard Space Flight Center in Greenbelt, Md. "The impact of the
space station as a useful technology test bed cannot be overstated.
Fresh satellite-servicing technologies will be demonstrated in a real
space environment within months instead of years. This is huge. It
represents real progress in space technology advancement."
Before a satellite leaves the ground, technicians fill its fuel tank
through a valve that is sealed, covered and designed never to be
accessed again. The RRM experiment demonstrates a remote-controlled
robot can remove these barriers and refuel such satellites in space.
Dextre successfully retrieved and inspected RRM tools, released safety
launch locks on tool adapters, and used an RRM tool to cut extremely
thin satellite lock wire. These operations represent the first use of
RRM tools in orbit and Dextre's first participation in a research and
development project.
RRM was developed by SSCO and is a joint effort between NASA and CSA.
During the next two years, RRM and Dextre will conduct several
servicing tasks using RRM tools on satellite parts and interfaces
inside and covering the cube-shaped RRM module.
NASA expects the RRM results to reduce the risks associated with
satellite servicing. It will encourage future robotic servicing
missions by laying the foundation for them. Such future missions
could include the repair, refueling and repositioning of orbiting
satellites.
"We are especially grateful to CSA for their collaboration on this
venture," Cepollina said. "CSA has played a pivotal role in the
development of space robotics, from the early days of the space
shuttle to the work they are doing with Dextre on space station."
During the three-day RRM Gas Fittings Removal task, the 12-foot
(3.7-meter) Dextre performed the most intricate task ever attempted
by a space robot: cutting two separate "lock wires" 20 thousandths of
an inch (0.5 millimeters) in diameter using the RRM Wire Cutter Tool
(WCT). Deftly maneuvered by ground-based mission operators and
Dextre, the WCT smoothly slid its hook under the individual wires and
severed them with only a few millimeters of clearance. This
wire-cutting activity is a prerequisite to removing and servicing
various satellite parts during any future in-orbit missions.
RRM operations are scheduled to resume in May 2012 with the completion
of the gas fittings removal task. The RRM Refueling task is scheduled
for later this summer. NASA and CSA will present RRM results at the
Second International Workshop on on-Orbit Servicing, hosted by
Goddard May 30-31, 2012.
Dextre and RRM are an example of how robots are changing operations in
space. Another is Robonaut 2, or R2, a project of NASA and General
Motors. R2, the first human-like robot, was launched into space in
2011 and is a permanent resident of the International Space Station.

OFF WORLD ASTRONAUTS SEEK TO CONTROL EARTH ROBOTS FROM SPACE
The following excerpt is from the NASA website:
MOFFETT FIELD, Calif. -- This semester, Academy of Art University
Industrial Design students will collaborate with the NASA Ames
Research Center, Moffett Field, Calif. to design a user interface
that will allow future astronauts in space to remotely operate a
robot on Earth. A number of thesis level students have been chosen
and will use a variety of design skills to complete the project,
including storyboarding, task analysis, ideation, brainstorming,
sketching and rendering. The students’ work will be used to create
the user interface elements, including icons wireframes and glyphs.
Simultaneously the team is identifying opportunities for additional
design disciplines to be integrated into the experience. Already the
team is starting conceptual work on interior architecture, product
design, and apparel.
"This is a once in a lifetime opportunity for students to contribute
to our country's innovative space program," said Dr. Elisa Stephens,
President of Academy of Art University. “We are constantly looking
for hands-on learning opportunities for our students so that while
they are in school, they get the real-world experience that will
prepare them for a career in their industry of choice. We are
grateful to NASA for working with us and are excited to see students
contribute to our nation’s space program."
The NASA project will require students to create storyboards that show
how astronauts in space can perform work on the ground using robots.
The students will also develop sketches and paper prototypes,
emphasizing graphical elements and other highly usable displays for
the astronauts. A group of NASA scientists will be present at the
Academy of Art University classes to work with the students and
students will also have an opportunity to visit NASA Ames during the
semester.
"Operating a robot is extremely complex and these designs we've tasked
the students with developing require both an in-depth knowledge of
engineering – and the advanced creative skills necessary to make
these designs user friendly for the astronauts,” said Dr. Terry Fong,
Director of the Intelligent Robotics Group at NASA Ames. “The final
products from the students will play a big role in how we think about
future astronaut-centered robotics, and we are grateful to the
Academy of Art for collaborating with us to explore the design space
in new ways."
Future human missions to the Moon, Mars, and other destinations offer
many new opportunities for exploration. With the limited amount of
work that astronauts can do from space, robots complement human
explorers by performing work on the ground under remote control from
spacecraft in orbit. Robots can perform tasks that are tedious,
highly repetitive or long-duration and beyond human capability.
In Summer 2013, NASA will perform an experiment in which astronauts on
the International Space Station remotely operate the "K10" mobile
robot on Earth. The astronauts will use K10 to layout a simulated
radio telescope on an outdoor terrain at the NASA Ames Research
Center. This work will require capturing images with the robot's
cameras and making measurements with other robot-mounted instruments.
The student designs will help NASA plan this and carry out this
engineering test.

NASA OFFERS NEW VIEW OF ORION NEBULA
The photo and excerpt below are from the NASA website:
This new view of the Orion Nebula highlights fledgling stars hidden in the gas and clouds. It shows infrared observations taken by NASA's Spitzer Space Telescope and the European Space Agency's Herschel mission, in which NASA plays an important role. Stars form as clumps of this gas and dust collapses, creating warm globs of material fed by an encircling disk. These dusty envelopes glow brightest at longer wavelengths, appearing as red dots in this image. In several hundred thousand years, some of the forming stars will accrete enough material to trigger nuclear fusion at their cores and then blaze into stardom. Spitzer is designed to see shorter infrared wavelengths than Herschel. By combining their observations, astronomers get a more complete picture of star formation. The colors in this image relate to the different wavelengths of light, and to the temperature of material, mostly dust, in this region of Orion. Data from Spitzer show warmer objects in blue, with progressively cooler dust appearing green and red in the Herschel datasets. The more evolved, hotter embryonic stars thus appear in blue. Infrared data at wavelengths of 8.0 and 24 microns from Spitzer are rendered in blue. Herschel data with wavelengths of 70 and 160 microns are represented in green and red, respectively. This image was released on Feb. 29, 2012. Image Credit: NASA/ESA/JPL-Caltech/IRAM

NATIONAL MUSEUM OF THE AIR FORCE WILL DISPLAY A SPACE SHUTTLE CREW COMPARTMENT TRAINER
The following excerpt below is from the Department of Defense Armed With Science website:
“By Rob Bardua
A retired NASA space shuttle crew compartment trainer is expected to arrive this summer at the National Museum of the U.S. Air Force.
The CCT is a high-fidelity representation of the Space Shuttle Orbiter crew station that was used primarily for on-orbit crew training and engineering evaluations.
It was in this trainer that astronauts learned how to operate many of the orbiter sub-systems in more than 20 different classes. All Air Force astronauts in NASA’s shuttle program trained in the CCT.
The crew module of the CCT consists of a flight deck and a mid-deck, and contains components such as panels, seats and lights visible to or used by the flight crew. Non-functional switches, connections, guards and protective devices all have the same physical characteristics, operating force, torque and movement as a real space shuttle.
The museum is currently working with NASA to package the CCT for airlift to the museum via NASA’s “Super Guppy” aircraft, which routinely carries outsized loads such as missile and rocket components. After arrival, technicians will offload the CCT and place it on interim display in the Cold War Gallery, before later moving it to a new Space Gallery in the planned fourth building.
According to the director of the National Museum of the U.S. Air Force, retired Lt. Gen. Jack Hudson, the CCT will be a great addition to the museum.
“When the CCT exhibit is completed, it will allow the public to have an up-close and personal look into the cockpit and mid-deck areas of a shuttle and learn how astronauts trained for their missions,” Hudson said. “We also plan to build a full-scale mock-up of the payload bay and develop other new exhibits with an emphasis on science, technology, engineering and math to further illustrate the rich history of the Air Force’s space programs and vital Air Force, NASA and aerospace industry partnerships.”
The new Space Gallery, where the CCT will eventually reside, is a part of a multi-phase, long-term expansion plan and will house the museum’s growing space collection. The gallery will include a Titan IV space launch vehicle; Mercury, Gemini and Apollo spacecraft; and many recently retired NASA artifacts such as a nose cap assembly, landing gear strut and a variety of astronaut equipment. In addition, a range of satellites and related items will showcase the Air Force’s vast reconnaissance, early warning, communications and other space-based capabilities. Other new exhibits will be developed to showcase Air Force technologies with many unique characteristics in design, propulsion, payload capacity, human factors, communication, range, speed and operating environment.
One of the unique features of the fourth building will be the creation of dedicated, interactive spaces for learning in the galleries. Three “Learning Nodes” will provide a unique environment for lectures and demonstrations, as well as extensions of the exhibit experience. These 60-seat “gallery classrooms” will allow museum staff to facilitate new science, technology, engineering and math experiences, while guest scientists and engineers from Air Force organizations, the aerospace industry, and area colleges and universities will be invited to share their expertise. Multimedia presentations will introduce students to air and space missions and the men and women responsible for their execution. When the nodes are not in use for scheduled programs, multimedia presentations will captivate public audiences.
The Air Force Museum Foundation, an IRS 501(c)(3) organization chartered to assist the National Museum of the United States Air Force with the development and expansion of facilities, is in the process of raising the funds to meet the growing requirements of the museum. Currently, $38 million has been secured by the Foundation for the fourth building project, which is expected to cost an estimated $48 million. The fourth building will house the Space Gallery, Presidential Aircraft Gallery and Global Reach Gallery featuring cargo and tanker aircraft.
The National Museum of the United States Air Force is located on Springfield Street, six miles northeast of downtown Dayton. It is open 9 a.m. to 5 p.m. seven days a week and is closed Thanksgiving, Christmas and New Year’s Day. Admission and parking are free.”

KOI961 PLANETARY SYSTEM CONDENSED
This artist's concept depicts a planetary system so compact that it's more like Jupiter and its moons than a star and its planets. Astronomers using data from NASA's Kepler mission and ground-based telescopes recently confirmed that the system, called KOI-961, hosts the three smallest exoplanets currently known to orbit a star other than our sun. An exoplanet is a planet that resides outside of our solar system. The star, which is located about 130 light-years away in the Cygnus constellation, is a red dwarf that is one-sixth the size of the sun, or just 70 percent bigger than Jupiter. The star is also cooler than our sun, and gives off more red light than yellow. The smallest of the three planets, called KOI-961.03, is actually located the farthest from the star, and is pictured in the foreground. This planet is about the size of Mars, with a radius of 0.57 times that of Earth. The next planet to the upper right is KOI-961.01, which is 0.78 times the radius of Earth. The planet closest to the star is KOI-961.02, with a radius 0.73 times the Earth's. All three planets whip around the star in less than two days, with the closest planet taking less than half a day. Their close proximity to the star also means they are scorching hot, with temperatures ranging from 350 to 836 degrees Fahrenheit (176 to 447 degrees Celsius). The star's habitable zone, or the region where liquid water could exist, is located far beyond the planets. The ground-based observations contributing to these discoveries were made with the Palomar Observatory, near San Diego, Calif., and the W.M. Keck Observatory atop Mauna Kea in Hawaii.

GEMINI VI ASTRONAUTS SUIT UP
Gemini VI astronauts Walter Schirra (seated), command pilot, and Thomas Stafford, pilot, go through suiting up exercises in preparation for their forthcoming flight in this image from October 1965. The suit technicians are James Garrepy (left) and Joe Schmitt. On the third attempt, Gemini VI successfully launched on Dec. 15, 1965. Once in orbit, Schirra and Stafford spent the next six hours catching up to the Gemini VII crew, consisting of commander Frank Borman and pilot James Lovell. Through careful maneuvering, Gemini VI and VII achieved their rendezvous with no relative motion between them. For the next three Earth revolutions, the two craft got as close as 0.30 meters, or about 1 foot apart. Image Credit: NASA

MOON SATELLITES HAVE BEGUN COLLECTING INFORMATION
The following excerpt is from the NASA website:
“WASHINGTON -- NASA's Gravity Recovery And Interior Laboratory (GRAIL)
spacecraft orbiting the moon officially have begun their science
collection phase. During the next 84 days, scientists will obtain a
high-resolution map of the lunar gravitational field to learn about
the moon's internal structure and composition in unprecedented
detail. The data also will provide a better understanding of how
Earth and other rocky planets in the solar system formed and evolved.
"The initiation of science data collection is a time when the team
lets out a collective sigh of relief because we are finally doing
what we came to do," said Maria Zuber, principal investigator for the
GRAIL mission at the Massachusetts Institute of Technology in
Cambridge. "But it is also a time where we have to put the coffee pot
on, roll up our sleeves and get to work."
The GRAIL mission's twin, washing-machine-sized spacecraft, named Ebb
and Flow, entered lunar orbit on New Year's Eve and New Years Day.
GRAIL's science phase began yesterday at 8:15 p.m. EST (5:15 p.m.
PST). During this mission phase, the spacecraft will transmit radio
signals precisely defining the distance between them. As they fly
over areas of greater and lesser gravity caused by visible features
such as mountains, craters and masses hidden beneath the lunar
surface, the distance between the two spacecraft will change
slightly. Science activities are expected to conclude on May 29,
after GRAIL maps the gravity field of the moon three times.
"We are in a near-polar, near-circular orbit with an average altitude
of about 34 miles (55 kilometers) right now," said David Lehman,
GRAIL project manager from NASA's Jet Propulsion Laboratory (JPL) in
Pasadena, Calif. "During the science phase, our spacecraft will orbit
the moon as high as 31 miles (51 kilometers) and as low as 10 miles
(16 kilometers). They will get as close to each other as 40 miles (65
kilometers) and as far apart as 140 miles (225 kilometers)."
Previously named GRAIL A and B, the names Ebb and Flow were the result
of a nation-wide student contest to choose new names for the
spacecraft. The winning entry was submitted by fourth graders from
the Emily Dickinson Elementary School in Bozeman, Mont. Nearly 900
classrooms with more than 11,000 students from 45 states, Puerto Rico
and the District of Columbia, participated in the contest.
JPL manages the GRAIL mission for NASA's Science Mission Directorate
in Washington. The GRAIL mission is part of the Discovery Program
managed at NASA's Marshall Space Flight Center in Huntsville, Ala.
Lockheed Martin Space Systems in Denver built the spacecraft.”

HUBBLE PANCHROMATIC VIEW OF GALAXY CENTAURIS A
“Resembling looming rain clouds on a stormy day, dark lanes of dust crisscross the giant elliptical galaxy Centaurus A. Hubble's panchromatic vision, stretching from ultraviolet through near-infrared wavelengths, reveals the vibrant glow of young, blue star clusters and a glimpse into regions normally obscured by the dust. The warped shape of Centaurus A's disk of gas and dust is evidence for a past collision and merger with another galaxy. The resulting shockwaves cause hydrogen gas clouds to compress, triggering a firestorm of new star formation. These are visible in the red patches in this Hubble close-up. At a distance of just over 11 million light-years, Centaurus A contains the closest active galactic nucleus to Earth. The center is home for a supermassive black hole that ejects jets of high-speed gas into space, but neither the supermassive black hole or the jets are visible in this image. This image was taken in July 2010 with Hubble's Wide Field Camera 3. Image Credit: NASA, ESA, and the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration Acknowledgment: R.

U.S. BUDGET AND SPACE MILITARY CAPABILITIES
The following excerpt is from a U.S. Defense Department American Forces Press e-mail:
Official: 2013 Budget Targets Space Capability Resilience
By Cheryl Pellerin
American Forces Press Service
WASHINGTON, March 9, 2012 - The $9.6 billion for space programs within President Barack Obama's fiscal year 2013 budget request will boost resilience for U.S. space capabilities but cut some modernization and other programs, Air Force Gen. William L. Shelton, commander of the Air Force Space Command, told a House panel yesterday.
Shelton testified on national security space activities before the House Armed Services Committee's strategic forces subcommittee, along with Ambassador Gregory L. Schulte, deputy assistant secretary of defense for space policy, Gil I. Klinger, deputy assistant secretary of defense for space and intelligence, and other experts.
The president's budget request, Shelton said, "invests in programs that enhance the resiliency and effectiveness of our space capabilities, namely missile warning, positioning, navigation and timing, satellite communications, space situational awareness and space launch."
A 22 percent drop in the 2013 request from 2012 represents mainly "fact-of-life programmatic changes," the general said, along with "some very difficult budget decisions leading to cuts to some modernization programs, and restructuring our approach" to the Operationally Responsive Space Office, or ORS, and the Space Test Program.
Congress established the ORS in 2007 to shorten the space acquisition cycle while responding to urgent warfighter needs. The Space Test Program has been providing access to space for the DOD space research and development community since 1965.
The command, Shelton said, also seeks to speed the acquisition process for the Advanced Extremely High-Frequency Program, a joint service satellite communications system for high-priority military ground, sea and air assets, and the Space-Based Infrared System, a key part of North America's missile early warning and defense system.
The general said the Air Force Space Command is working closely with NASA and the National Reconnaissance Office to "bring stability and predictability to our launch programs."
Schulte told the panel that three elements are critical to the U.S. strategy in space: resilience, promoting responsible behavior in space, and energizing the space industrial base.
Examples of resiliency, he said, include hosted payloads, commercial augmentation, international cooperation and backup capabilities in other domains.
In 2008, the European Union published a draft Code of Conduct for Outer Space Activities and a revised draft in 2010.
"The EU's draft is a promising basis for an international code," Schulte said.
"It focuses on reducing the risk of creating debris and increasing transparency of space operations. It is not legally binding and recognizes the inherent right of self-defense. It addresses behavior rather than unverifiable capabilities and better serves our interests than the legally binding ban on space weapons proposed by others," he added.
"As we participate in the development of an international code," Schulte told the panel, "the department is committed to ensuring that it advances our national security."
The ambassador said the United States could energize the space industrial base by allowing industry to compete internationally for the sale of satellites and technologies that are already widely available.
Today, some commercial satellite components reside on the Munitions List, a registry of items subject to the International Traffic in Arms Regulations because they are considered dual-use exports -- those that can be used for peaceful and military ends. The State Department strictly regulates and licenses such exports.
Last year, Schulte said, the departments of Defense and State concluded that commercial communications satellites and related components, with a few exceptions, can be moved from the U.S. Munitions List to the Commerce Control List without posing an unacceptable security risk.
The forthcoming final report, he added, will identify more items that can be safely moved.
"This approach -- higher fences around fewer items -- will require new legislation," he told the panel.
"Your support can help energize our industrial base and thereby enhance our national security," Schulte added. "Giving our industrial base new commercial opportunities is particularly important at a time of defense spending constraints."
Deputy Assistant Secretary Klinger told the panel that DOD is recapitalizing virtually all its space lines of business, "and doing so at precisely a time of sharply constrained resources and as the nation remains at war."
The department is doing the following:
- Executing oversight earlier in the acquisition process so program managers can achieve authority to proceed early and then focus their energies on program execution.
- Using fixed-price contracts, more innovative contracting and evolutionary upgrades where those make sense.
- Pursuing a block buy for the Advanced Extremely High-Frequency 5 and 6 satellite programs and developing a plan to use the savings to improve the capability of military satellite communications overall.
"This is extremely important as we plan ahead to maintain the resources to protect our seed corn of promising technologies," Klinger said. "We intend to use competition where and when it makes sense."

VIEW OF GALAXY NGC 1483
The excerpt and picture below are from the NASA website:
NASA's Hubble Space Telescope has produced this beautiful image of the galaxy NGC 1483. NGC 1483 is a barred spiral galaxy located in the southern constellation of Dorado — the dolphinfish (or Mahi-mahi fish) in Spanish. The nebulous galaxy features a bright central bulge and diffuse arms with distinct star-forming regions. In the background, many other distant galaxies can be seen. The constellation Dorado is home to the Dorado Group of galaxies, a loose group comprised of an estimated 70 galaxies and located some 62 million light-years away. The Dorado group is much larger than the Local Group that includes the Milky Way (and which contains around 30 galaxies) and approaches the size of a galaxy cluster. Galaxy clusters are the largest groupings of galaxies (and indeed the largest structures of any type) in the universe to be held together by their gravity. Barred spiral galaxies are so named because of the prominent bar-shaped structures found in their center. They form about two thirds of all spiral galaxies, including the Milky Way. Recent studies suggest that bars may be a common stage in the formation of spiral galaxies, and may indicate that a galaxy has reached full maturity. Image Credit: ESA/Hubble & NASA

STATE DEPARTMENT REPRESENTATIVE REMARKS ON SPACE "SUSTAINABILITY"
The following excerpt is from the U.S. State Department:
Sustaining the Space Environment for the Future
Remarks Frank A. Rose
Deputy Assistant Secretary, Bureau of Arms Control, Verification and Compliance American Center
Hanoi, Vietnam
March 8, 2012
I am pleased to join you here today to discuss space, its importance to our daily lives, and the need for international cooperation to maintain the long-term sustainability of the space environment. I’ll explain what I mean by that during the course of my talk. Of course, I speak from an American perspective, but I am also here to gain a better understanding of Vietnam’s interests in space.
As we’ve just discussed, space plays a vital role in almost every aspect of our daily lives worldwide. Space systems enable us to communicate around the world; facilitate financial operations; enhance weather forecasting and environmental monitoring; and enable navigation globally and locally on highways and streets in personal automobiles. Space also expands our scientific frontier; warns us of natural disasters; and helps us monitor arms control treaties and increase stability among nations.
Just as our use of space has evolved in the past fifty-five years since the first satellite, Sputnik, was launched from Earth, the space environment has also been transformed by actors and their actions. When the space age began, the opportunities to use space were available to only a few nations, and there were limited consequences for irresponsible behavior or accidents. Today, space is the domain of a growing number of satellite operators; approximately 60 nations and government consortia operate satellites, including Vietnam, as well as numerous commercial and academic satellite operators. This great transformation of the space environment has greatly benefited the global economy and has brought people around the world closer together, but it also presents challenges.
While it is becoming increasingly easier to access, as well as to benefit from, space is also becoming increasingly congested. Many countries and space operators have great plans to increase their space capabilities in the near future. Vietnam, for example, plans to put approximately 14 satellites into orbit by 2020, a feat which will make Vietnam the fastest growing space power in Southeast Asia. However, decades of space activity have littered Earth’s orbit with debris. As the world continues to increase its activities in space, the possibility of collisions in space also increases. This situation means we need to think carefully through how we can all operate there safely and responsibly so that we can ensure that your generation, and the generations that follow you, can also benefit from space as well. The interconnected nature of space capabilities and the world’s growing dependence on them mean that irresponsible acts in space can have damaging consequences for all of us.
You’re probably wondering how a big, seemingly empty environment like space could be so crowded that we worry about collisions. While it’s true that a lot of space is relatively empty, most of our operations are conducted close to Earth, including the operations of Vietnam’s communication satellite Vinasat 1. It is this environment that is becoming increasingly congested. The U.S. Department of Defense tracks roughly 22,000 objects in various orbits, of which only 1,100 are active satellites. That’s about 6000 metric tons of debris orbiting the Earth, and these numbers do not include the hundreds of thousands of pieces of debris smaller than 10 centimeters that are too small to track, but just as potentially deadly to satellites and manned spaceflight when traveling at speeds of up to 17,000 kilometers an hour.
Some pieces of debris are simply “dead” satellites or pieces of the rockets that got them there, but others are the results of accidents or mishaps, such as from the 2009 collision between two satellites. Some debris, however, is the result of intentionally destructive events, such as China’s test in space of an anti-satellite weapon in 2007. Experts warn that the current quantity and density of man-made debris significantly increases the odds of future damaging collisions. 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.
The international community is more reliant on space than ever and the long-term sustainability of our space activities is at serious risk from space debris, as I just described, and from irresponsible actors and their actions. Irresponsible acts against space systems would not just harm the space environment, but would also disrupt services that the citizens, companies, and militaries around the world depend on. Ensuring the long-term sustainability, stability, safety, and security of the space environment is in the vital interests of the United States and the entire global community.
Improving the long-term sustainability and stability of space begins first with enhancing our shared situational awareness and understanding of what is in space, sharing information to avoid collisions of space objects, and working internationally to minimize the problems of orbital debris. To that end, the United States works with other nations, commercial entities, and intergovernmental organizations to improve our shared ability to rapidly detect, warn of, characterize, and attribute natural and man-made disturbances to space systems. Such improvements illustrate the ongoing commitment of the United States to promoting the safety of flight for all space-faring nations.
The United States also collaborates with industry and foreign nations to improve space object databases and warn of dangerous approaches between orbiting objects that could potentially lead to collisions. This is particularly important given collisions such as the February 2009 collision between a privately operated Iridium communications satellite and an inactive Russian military satellite, as well as a lot of near-collisions. To help prevent future collisions, the United States has improved its capacity to analyze objects in space and to predict potential hazards to spacecraft. The United States also provides notifications to other government and commercial satellite operators when U.S. space analysts predict that an operator’s satellite may pass within a close distance of another spacecraft or space debris.
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. The United States has adopted international standards to minimize debris that are stricter than the U.N. Space Debris Mitigation Guidelines. We are also working to develop stricter international and industry standards to slow down the accumulation of debris in space, and to develop and implement international “best practices” of responsible behavior in space that will put us all on a more sustainable path.
Finally, the United States is also pursuing pragmatic transparency and confidence-building measures – or TCBMs – to strengthen stability in space and promote safe and responsible operations in space. TCBMs are a means by which governments can address challenges and share information with the aim of creating mutual understanding and reducing tensions. Through TCBMs we can address 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.
Perhaps one of the most beneficial TCBMs for ensuring sustainability and security in space could be the adoption of “best practice” guidelines or a “code of conduct.” On January 17th of this year, 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 the Asia-Pacific Region, both Japan and Australia have also endorsed developing such an International Code of Conduct. In her statement announcing the decision, Secretary of State Clinton said,
“The long-term sustainability of our space environment is at serious risk. […] 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.”
The United States views the European Union’s draft Code of Conduct as a good foundation for working with other spacefaring nations to develop a non-legally binding International Code. An International Code of Conduct, if adopted, would help prevent mishaps, misperceptions, and mistrust in space by establishing guidelines to reduce the risks of debris-generating events and to avoid the danger of collisions. As more countries field space capabilities, it is in all of our interests to work together to establish internationally-accepted “best practices” to ensure that the safety and sustainability of space is protected.
Today, the world is increasingly inter-connected through space, and we are increasingly dependent on space systems. The risks associated with irresponsible actions in space mean that ensuring the long-term sustainability and stability of the space environment is in the vital interest of the entire world community. As the U.S. National Space Policy says, “All nations have the right to use and explore space, but with this right also comes responsibility. […] [I]t is the shared interest of all nations to act responsibly in space to help prevent mishaps, misperceptions, and mistrust.” The United States calls on governments around the world to work together to adopt approaches for responsible activity in space in order to preserve this right for the benefit of future generations.
Thank you very much.”
