摘要:
The first priority of the U.S. space program should be scientific research, not manned spaceflight, according to a high‐level NASA advisory committee, chaired by Martin Marietta chief executive officer Norman R. Augustine, that reported its findings in December. The committee's recommendations, which also include a 10% annual increase in NASA's budget through the 1990s and a cost‐cutting redesign of Space Station Freedom, were well received January 3 on Capitol Hill during the first of a series of Congressional hearings on the committee's report.The report identifies four content areas that make up the U.S. civil space program—space science, Earth observation missions, manned exploration of the Solar System, technology and launch systems—and states that “the civil space science program should have first priority for NASA resources.” That funding level is to be maintained at a constant level of approximately 20% of NASA's budget. The report also recommends that NASA increasingly use universities and other organizations as “prime contractors for space research instruments

摘要:
As Congress convenes again and enters a new budget cycle, it theoretically follows a two‐tiered approach to funding a program. First, a congressional committee is supposed to authorize spending for a program, and then another committee appropriates the money for it. Authorizing committees are also charged with overseeing and adjusting programs.One authorizing committee, however—the House Science, Space, and Technology Committee, newly chaired by George A. Brown (D‐CA)— has lost some of its power to formulate the nation's science policy to the House Appropriations Committee. One of Brown's challenges—cited by observers—is to regain some of his committee's old control on setting the course

摘要:
The National Space Science Data Center, Greenbelt, Md., recently published “Solar Terrestrial Models and Applications Software,” by Dieter Bilitza (NSSDC 90‐19, July 1990, 98 pp.), which identifies and describes more than 70 model software packages in several areas of the solar‐terrestrial environment. Some of these may be accessed and run on the NSSDC Online Data and Information Services (NODIS) account by external researchers.The principal areas and parameters covered include ionosphere (electron density and temperature, ion temperature, composition, and drift, electric field and current, precipitating particle flux, etc.), atmosphere (density, temperature, winds, etc.), magnetosphere (internal‐ and external‐source geomagnetic fields, energetic proton and electron fluxes, etc.), Sun and interplanetary space (IR and EUV reference spectra, solar protons, cosmic rays, etc.) and Venus atmosphere and ionosphere. Representative models include the International Reference Ionosphere (IRI), the Heppner‐Maynard‐Rich ionospheric electric field model, the Committee on Space Research (COSPAR) Interna tional Reference Atmosphere (CIRA), the International Geomagnetic Reference Field (IGRF), the Tsyganenko geomagnetic models (1982, 1987, and 1989), the AP8 and AE8 trapped particle models, the revised SERF2 solar EUV Flux model [Tobiskas, 1990], the Jet Propulsion Laboratory solar proton model, and the CREME cos
