This gap developed because of the rapid and successful implementation- of several priority space missions, an unfortunate mismatch of schedules, and changes in the way government agencies are required to plan their future budgets. In recent years NASA has adopted a systematic approach to strategic planning for all of its scientific activities, in part because of the changing environment for research funding and also in response to the requirements of the Government Performance and Results Act (GPRA)

In essence the current report could be viewed as a framework around which the preliminary activities of the next survey committee could be organized. RELATIONSHIP TO THE SPACE STUDIES BOARD'S OTHER SPACE SCIENCE STRATEGIES Given the breadth of topics encompassed by space astronomy and astrophysics and the even wider range of scientific enquiries utilizing facilities and techniques usually associated with astronomical studies, it is not surpnsing that certain research topics fall within the spheres of influence of several different scientific communities.

In summary, TGSAA's basic approach to prioritization was as follows: · Concentrating on scientific objectives rather than emphasizing the methods by which the objectives are implemented; · Adopting a multiwavelength approach by prioritizing scientific questions of significance to whole classes of astronomical objects and not limiting discussion to individual observing bands; and · Being realistic with respect to such practical matters as cost and technical feasibility. ~ ~ con - ~ ASSUMPTIONS For a variety of reasons ranging from redirected federal budgets and hardware failures to technological advances and changing scientific emphasis, the U.S.

The following general principles, espoused in past SSB reports,~° should be borne in mind when cooperative activities are being considered: · Selection of foreign scientists and experiments for U.S. missions should be based on scientific merit, and the free flow of scientific data and results should be a condition for any cooperative arrangements; · NASA should consider all appropriate foreign capabilities available for planning and carrying out its missions and should cultivate those that enhance the scientific return; and · NASA should fully involve the scientific community in planning for international cooperation and in assessing proposed cooperative missions.

ORGANIZATION OF THIS REPORT To set overall scientific priorities from among the broad range of topics in space astronomy and astrophysics, TGSAA organized itself into four panels, each dealing with a number of closely related fields of research, along the following lines: . Planets, star formation and the interstellar medium, including the search for extrasolar planets, how stars and planets form, and the evolution of the interstellar medium in galaxies (Chapter 23; · Stars and stellar evolution, including the life cycles of stars, the origin of the chemical elements, and the use of stars as celestial laboratories (Chapter 3~; .
