Decadal Survey (astronomy and astrophysics) is a series of community-driven priority-setting reports produced roughly every ten years that guide investments in National Aeronautics and Space Administration, National Science Foundation, and Department of Energy astronomy and astrophysics programs. The surveys are organized under the auspices of the National Academies of Sciences, Engineering, and Medicine and draw input from professional societies such as the American Astronomical Society, the American Physical Society, and the International Astronomical Union alongside observatory directors from institutions like the Space Telescope Science Institute and the Jet Propulsion Laboratory. Each survey synthesizes advice from panels, workshops, and town halls involving researchers affiliated with universities such as Harvard University, Massachusetts Institute of Technology, and University of California, Berkeley as well as national laboratories including Lawrence Berkeley National Laboratory and Fermi National Accelerator Laboratory.

Overview

The Decadal Survey series functions as a consensus roadmap used by agencies including NASA, NSF, and DOE to prioritize missions, facilities, and programs such as space telescopes, ground-based observatories, and instrumentation projects. Reports are produced by committees convened by the National Research Council within the National Academies and reflect input from stakeholders such as the American Astronomical Society, the Royal Astronomical Society, and funding bodies like the European Space Agency and the Japanese Aerospace Exploration Agency. Surveys generate ranked recommendations—often highlighting flagship missions analogous to Hubble Space Telescope, James Webb Space Telescope, and the Large Synoptic Survey Telescope (now Vera C. Rubin Observatory)—and are widely cited by Congress, the United States Congress appropriation committees, and executive branch agencies including the Office of Science and Technology Policy.

Originating in the 1960s, early community planning efforts were influenced by leaders at institutions such as the Smithsonian Astrophysical Observatory, California Institute of Technology, and figures including Lyman Spitzer Jr. and Riccardo Giacconi. The formalization into decadal studies occurred under the auspices of the National Academy of Sciences with committees composed of astronomers associated with Princeton University, University of Chicago, and Columbia University. Successive reports in the 1970s, 1980s, 1990s, 2000s, and 2010s incorporated recommendations that led to projects like Chandra X-ray Observatory, Spitzer Space Telescope, Kepler Space Telescope, Atacama Large Millimeter/submillimeter Array, and Thirty Meter Telescope, involving collaborations with organizations such as European Southern Observatory and National Radio Astronomy Observatory.

Each survey is assembled by a steering committee appointed by the National Academies drawing on panels covering areas like cosmology, exoplanets, star formation, and multi-messenger astrophysics—with experts from Stanford University, Yale University, University of Cambridge, and University of Tokyo. Solicitation of white papers involves professional societies including the American Astronomical Society and the International Astronomical Union and engages program officers from NASA Headquarters and NSF Directorate for Mathematical and Physical Sciences. Methodology integrates cost and technical assessments prepared by organizations such as NASA Jet Propulsion Laboratory and Ball Aerospace, programmatic trade studies, and budget scenarios informed by congressional appropriations and agency strategic plans like those from the Office of Management and Budget and the White House Office of Science and Technology Policy.

Past surveys have recommended flagship priorities that became missions and facilities in partnership with entities including NASA, NSF, DOE, European Space Agency, and industry partners like Lockheed Martin and Northrop Grumman. Notable outcomes linked to survey recommendations include the development of Hubble Space Telescope, Chandra X-ray Observatory, Spitzer Space Telescope, James Webb Space Telescope, Kepler Space Telescope, Vera C. Rubin Observatory, Atacama Large Millimeter/submillimeter Array, Square Kilometre Array, and concepts such as the Large Ultraviolet Optical Infrared Surveyor and the Habitable Exoplanet Observatory. Endorsements have influenced ground-based projects like the Thirty Meter Telescope and European Extremely Large Telescope and space-based missions proposed to agencies including NASA and ESA.

Decadal Survey recommendations are frequently cited by United States Congress appropriations committees, Office of Management and Budget, and agency leadership at NASA and NSF when setting budgets and strategic priorities. Endorsements have steered major capital investments at national facilities such as the National Radio Astronomy Observatory and university consortia at California Institute of Technology and University of Arizona, and informed international collaborations with European Southern Observatory and Canadian Space Agency. Surveys also interact with policy mechanisms like the Federal Advisory Committee Act and have been referenced in hearings before the United States Senate Committee on Commerce, Science, and Transportation and the United States House Committee on Science, Space, and Technology.

Critiques have arisen from stakeholders including groups at University of California, University of Hawaiʻi at Mānoa, and indigenous communities near observatory sites such as those involved with Mauna Kea and the Thirty Meter Telescope controversy; these critiques address prioritization, cost growth, and community engagement. Other controversies involve cost overruns linked to missions like James Webb Space Telescope and scheduling impacts affecting projects at NASA Jet Propulsion Laboratory and observatory consortia including the Association of Universities for Research in Astronomy. Debates have engaged professional societies such as the American Astronomical Society and panels convened by the National Academies over transparency, equity in committee composition, and the balance between flagship missions and individual investigator programs supported by NSF and DOE.
