The Planetary Science and Astrobiology Decadal Survey 2023-2032 will assess key scientific questions in planetary science and astrobiology, identify priority medium- and large-class missions and other initiatives, and present a comprehensive research strategy for the 2023-2032 timeframe. Community input in these areas and related activities—including, theory, computing, technology development, laboratory studies, planetary defense, and human exploration activities—are critical for the success of the survey. Many opportunities will exist to share your thoughts with the survey. Sign up for our mailing list to receive updates on calls for input and other study activities.
