NASA BUDGET CUTS CONTINUE, SENATE OFFERS SOME HOPE

The House of representatives approved HR 2684, the legislation containing 1 Billion dollar budget cuts for NASA. The vote was 235 for, 187 against. The vote was split along party lines with 18 Republicans voting against and 39 democrats voting for the bill. The $1 billion decrease to the NASA budget is the largest cut since the end of the Apollo program. Several programs have been severely reduced or zeroed out, which virtually guarantees their termination. This bill cancels funding for the Space Infrared Telescope Facility, and decreases funding for the Explorer program, Discovery program, and Mars missions support funding for research and technology for space science. Several missions are named to be cut if these budget cuts hold. Space science programs at GSFC, JPL and JHUAPL are hit especially hard by these cuts. There is sentiment in the Senate to restore the NASA budget, but the vote could be close. Please contact your Senator and the Senate Appropriations Committee to tell them how you feel about their vote on this legislation that critically reduces the budgets for the NASA Office of Space Science from both the President's proposed FY '00 budget. This may be important to you if your employment is coupled to a healthy space industry. If your Senators strongly support restoring the funds, encourage family members in other states to contact their Senators.

NASA Administrator Dan Goldin said. "The NASA employees have risen to the challenge of smaller budgets. And this is the reward the NASA team gets? Not only is this cut devastating to NASA's programs, it is a knife in the heart of employee morale." Goldin said. "These cuts would gut space exploration. Significant layoffs would most certainly follow."

The American Astronomical Society suggest that you include a direct request to your Senator to contact Senator Mikulski and Senator Bond, who are the ranking minority member and chairman (respectively) of the Senate sub-committee. They will be responsible for crafting the draft legislation that will be forwarded to the full Senate appropriations committee. You can find the address for your Senators and Members of Congress at the roll call site and discussions of the latest status at the AAS site. I will post a model letter on the ATI courses web site as part of the expanded newsletter. Since time is important, you may wish to fax the letter.

Honorable (full name)

(insert address from roll call site)Senate Office Building
Washington, DC 20510

Dear Senator:

I write to you to support fully funding the Administration's budget request for the National Aeronautics and Space Administration (NASA). I believe that space science program continues to be a vital part of America's technology development and urge you to help restore the 1 billion dollars cut by the House. Over the years NASA has been prudently and steadily pushing the frontiers of science. This work has helped maintain the economic growth of the United States. Spin-offs from the space program all well documented and benefit all citizens.

Space employment is important to the State of (insert). (Insert Company) is a major employer in the state and will certainly be hurt by the decline of the space budget. (Add more details if appropriate)

I strongly urge you to vote to support restoring the full proposed NASA budget. Please contact Senator Mikulski and Senator Bond to express your support for restoring NASA funding.

Yours truly,

 

James Jenkins

NASA UNVEILS FIRST IMAGES FROM CHANDRA The Chandra X-Ray Observatory is producing images to give scientists around the world a better understanding of the structure and evolution of the universe. It will provide unprecedented X-ray images and spectra of violent, high-temperature events and objects. It is is designed to observe X-rays from high energy regions of the universe, such as hot gas in the remnants of exploded stars. Extraordinary first images from NASA's Chandra X-ray Observatory trace the aftermath of a gigantic stellar explosion in such stunning detail that scientists can see evidence of what may be a neutron star or black hole near the center. Another image shows a powerful X-ray jet blasting 200,000 light years into intergalactic space from a distant quasar. Released today, both images confirm that NASA's newest Great Observatory is in excellent health and its instruments and optics are performing up to expectations. Chandra, the world's largest and most sensitive X- ray telescope, is still in its orbital check-out and calibration phase. "When I saw the first image, I knew that the dream had been realized," said Dr. Martin Weisskopf, Chandra Project Scientist, NASA's Marshall Space Flight Center, Huntsville, AL. "This observatory is ready to take its place in the history of spectacular scientific achievements." "We were astounded by these images," said Harvey Tananbaum, Director of the Smithsonian Astrophysical Observatory's Chandra X- ray Center, Cambridge, MA. "We see the collision of the debris from the exploded star with the matter around it, we see shock waves rushing into interstellar space at millions of miles per hour, and, as a real bonus, we see for the first time a tantalizing bright point near the center of the remnant that could possibly be a collapsed star associated with the outburst."

Chandra also imaged a distant and very luminous quasar -- a single star-like object -- sporting a powerful X-ray jet blasting into space. The quasar radiates with the power of 10 trillion suns, energy which scientists believe comes from a supermassive black hole at its center. Chandra's image, combined with radio telescope observations, should provide insight into the process by which supermassive black holes can produce such cosmic jets. "Chandra has allowed NASA to seize the opportunity to put the U.S. back in the lead of observational X-ray astronomy," said Dr. Edward Weiler, Associate Administrator of Space Science, NASA Headquarters, Washington, DC. "History teaches us that whenever you develop a telescope 10 times better than what came before, you will revolutionize astronomy. Chandra is poised to do just that." The Smithsonian's Chandra X-ray Center controls science and flight operations from Cambridge, MA. The first Chandra images will be posted to the Internet at: http://chandra.nasa.gov and http: //chandra.harvard.edu

NASA SELECTS MINIATURE SPACECRAFT TO TEST SPACE TECHNOLOGY They're each about the size of a large birthday cake, weigh about as much as a desktop computer, and are smart enough to fly in formation far from Earth while they test new technologies. They are three very small satellites, called the Nanosat Constellation Trailblazer mission, and today NASA selected them as the agency's latest New Millennium mission. The mission will validate methods of operating several spacecraft as a system, and test eight technologies in the harsh space environment near the boundary of Earth's protective magnetic field, or magnetosphere. Each Trailblazer spacecraft will be an octagon 16 inches across and 8 inches high, and each will have booms and antennas that will extend after launch. The mission will cost $28 million and will be launched in 2003 as a secondary payload on an expendable launch vehicle. The mission is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. Results from the Tra ilblazer mission will be used to design future missions using constellations of lightweight (about 44 pounds), highly miniaturized autonomous spacecraft. One proposed constellation of up to 100 spacecraft positioned around the Earth will monitor the effects of solar activity that can affect spacecraft, electrical power and communications systems. Others will study global precipitation and the atmospheres of other planets. The Nanosat Constellation Trailblazer is the fifth in the agency's New Millennium program, which tests technology for future space and Earth science missions. The program's goal is to dramatically reduce the weight, size and costs of missions while increasing their science capabilities. The technologies to be flown and tested, and the partners involved, are: -- A miniature communications system to determine the positions of the spacecraft using the Global Positioning System (NASA's Jet Propulsion Laboratory, Pasadena, CA). -- A set of software that automatically operates the spacecraft and d etermines orbits (Bester Tracking System, Emeryville, CA). -- A communications system component that uses one-fourth the voltage and half the power, weighs 12 times less and is nine times smaller than proven technology (Aero Astro, Boston, MA). -- A new method of connecting electrical lines that saves weight (Lockheed Martin, Denver, CO). -- A new type of microelectronic device that is more reliable and uses 20 times less power than proven technology (Goddard Space Flight Center and the University of New Mexico, Albuquerque). -- An electrically tunable coating that can change its properties from absorbing the Sun's heat when the spacecraft is cool to reflecting or emitting heat when needed (Goddard Space Flight Center and the Johns Hopkins University Applied Physics Lab, Laurel, MD). -- A very tiny microelectromechanical system chip that provides fine attitude adjustments on the spacecraft using 8.5 times less power and weighing less than half as much as proven systems (Marotta Scientific Controls, Montville, NJ). -- Development of a Lithium Ion Power System for Small Satellites. A rechargeable lithium ion battery that stores two to four times more energy and has a longer life than proven technology (Yardney Technical Products, Pawcatuck, CT). "Not only could these technologies make future missions more productive and less expensive, some could become consumer products," said Dr. Dana Brewer, New Millennium Program Executive, NASA Headquarters, Washington, DC. "For example, the variable- emittance thermal-control system is a coating applied to surfaces such as automobile windows which becomes highly reflective when you apply an electrical current to it. It blocks out a lot of the sunlight, keeping it cooler inside a car."

AEROASTRO WINS CONTRACT TO STUDY NANOSATELLITES

AeroAstro, Inc., a premier small satellite technology company, has announced it has been awarded a contract for $150,000 by the U.S. Air Force Research Laboratory to study the tactical use of nanosatellites for military applications. AeroAstro will incorporate its new Bitsy Nanosatellite Core Module in its research. Bitsy integrates satellite subsystems such as power, communications, command, and data/guidance into a single component, known as a core kernel module. Systems such as structure, solar arrays, and attitude control are built up around it for each mission, thereby increasing flexibility while keeping costs low.

The company has also been recently awarded several contracts by NASA to develop Bitsy and other nanosatellite technology for Future-X, New Millennium, and Small Business Innovative Research (SBIR) programs. Dr. Rick Fleeter, President and CEO of AeroAstro, said, "Nanosatellites offer a way to use space in a radically different mode from traditional spacecraft.

We can provide production runs of spacecraft, each cheaper than a sounding rocket payload, available on-demand. These not only enable new types of space missions, they also allow businesses, researchers and students immediate, affordable access to space.
