A Tabulated Characteristics of the NASA Astronomy Science Centers CENTERS AND THEIR MISSIONS The charge to the committee included a request for "a comparative review of current astronomy science centers in terms of the kinds of roles and services that they provide, their size (e.g., budget, staff) , the extent to which they utilize centralized or distributed approaches to their architecture, the roles and status of their staff, the nature of their host or governing institution, governance structure, how they were established by NASA (e.g., sole source versus competition)

, a bureau of the Smithsonian Institution. SAO conducts a mix of government and contract and grant-funded work. In principle, and barring a catastrophic failure, the CXO could have a very long lifetime. Spitzer Science Center SSC was founded in 1997, without competition but with review of the assignment by the Space Infrared Telescope Facility (SIRTF)

cThe NASA mission budget includes science and mission operations costs at the science centers and grants to the com munity plus: science and mission operations costs at the related NASA centers; industrial contractors; and PI sustaining engineering. It does not include new PI-led instrument development, servicing mission costs, or foreign contributions. dThe total budget for the science centers themselves; that is, only those items shown in italics in footnote c.

Space Telescope Science Institute/James Webb Space Telescope In 1999, NASA determined that technical, budget, and schedule risk in JWST development would be minimized by placing the JWST science and operations center at STScI, to build on the HST heritage and to exploit the numerous synergies with that mission. The center is located on the campus of the Johns Hopkins University. Its governing institution is AURA, a private, not-for-profit research management organization owned by 32 U.S. universities. GSFC is a related location where JWST development is led.

, and other contracts. In all cases the table only gives data for the mission shown. NASA Budget for Centers The budget recorded by NASA for the science center of one of its astronomical missions differs from the budget on which the center operates. The NASA amount is what is sent to the NASA field center responsible for the mission. That field center either operates the mission's science center itself or contracts with a third party to operate it. A NASA center spends the difference between the two budget amounts on a variety of activities, which include science and mission operations costs at the center and the costs of industrial contracts. It does not, however, pay for developing the instruments for a PI-led mission nor, in the case of HST, for servicing mission costs. Nor are foreign contributions included.

Number of Users Served As an indicator of the size of the community served by a center, Table A.1 lists the number of individuals, counted once, who were PIs or co-investigators on an approved observing or archive proposal in 2004. This number includes foreign investigators. Number of User Grants Table A.1 shows the number of grants to users for data analysis in 2004. Because only PI grants are shown, not grants to co-investigators as well, the numbers here reflect the number of observing programs rather than the total number of people supported, which is greater.
