NASA’s Science Mission Directorate, Universe Division, Washington, selected several institutions for grants to support the agency’s Rossi X-ray Timing Explorer program.

NASA solicited proposals for the program that provide acquisition and analysis of scientific data. The primary goal of this mission is to investigate the nature and physics of compact astrophysical objects as revealed through temporal variations in their high energy emission on time scales from microseconds to years. Funding for awardees is being negotiated. Grants are generally for one year.

NASA selected: Marshall Space Flight Center, Universities Space Research Association, Dynetics Inc., all of Huntsville, Ala.; Stanford University, U.C. Santa Cruz and U.C. San Diego, Calif.; Yale University, New Haven, Ct.; Naval Research Laboratory, Washington; Georgia State University, Atlanta; University of Iowa, Iowa City; Purdue University, Lafayette, Ind.; Boston University; MIT, Harvard-Smithsonian Center for Astrophysics and Smithsonian Astrophysical Observatory, Cambridge, Mass.; Goddard Space Flight Center, Greenbelt, University of Maryland-Baltimore County, Baltimore, Md.; Washington University in St. Louis; New Mexico State University, Las Cruces; Columbia University, New York; Pennsylvania State University, University Park; and George Mason University, Va.

The research also supports the Vision for Space Exploration, NASA’s long- term plan to return astronauts to the moon and extend exploration to Mars and beyond.
