Exoplanet Science Strategy is a coordinated framework guiding observational programs, theoretical research, and technology development for the detection, characterization, and contextualization of planets beyond the Solar System. It aligns priorities across agencies such as NASA, European Space Agency, National Science Foundation, Japan Aerospace Exploration Agency, European Southern Observatory, and Canadian Space Agency while engaging missions like Kepler (spacecraft), Transiting Exoplanet Survey Satellite, James Webb Space Telescope, Hubble Space Telescope, and observatories including Atacama Large Millimeter Array, Very Large Telescope, Thirty Meter Telescope, and Square Kilometre Array.

Overview and Objectives

The strategy defines near-term goals tied to programs at NASA Ames Research Center, Jet Propulsion Laboratory, Harvard-Smithsonian Center for Astrophysics, and Max Planck Institute for Astronomy and long-term ambitions influenced by initiatives at Carnegie Institution for Science, California Institute of Technology, Massachusetts Institute of Technology, University of Cambridge, and University of Oxford. Core objectives prioritize census efforts exemplified by Kepler (spacecraft) and Transiting Exoplanet Survey Satellite; atmospheric characterization programs exemplified by James Webb Space Telescope and Hubble Space Telescope; and ground-based high-resolution spectroscopy campaigns at European Southern Observatory and W. M. Keck Observatory. The plan coordinates community roadmaps from panels convened by National Academies of Sciences, Engineering, and Medicine, Committee on Astrobiology and Planetary Science, and advisory groups associated with American Astronomical Society and Royal Astronomical Society.

Top priorities include frequency and distribution studies tracing results from Kepler (spacecraft), demographic analyses akin to work at Space Telescope Science Institute, and habitability assessments inspired by research at SETI Institute and Blue Marble Space Institute of Science. Key questions address formation pathways linked to models from Max Planck Institute for Astronomy and Institut d'Astrophysique de Paris, migration mechanisms explored in studies by Princeton University and University of California, Berkeley, and atmospheric evolution probed by teams at Northwestern University and University of Chicago. Biosignature identification relates to expertise at NASA Goddard Space Flight Center and Carnegie Institution for Science, while habitability zone refinement builds on work from University of Arizona and Australian National University.

Techniques span transit photometry pioneered by Kepler (spacecraft), radial velocity measurements refined at W. M. Keck Observatory and European Southern Observatory, direct imaging advanced by Gemini Observatory, nulling interferometry concepts developed at Jet Propulsion Laboratory, and microlensing surveys associated with Optical Gravitational Lensing Experiment and Nancy Grace Roman Space Telescope. Instrumentation roadmaps involve coronagraphs tested by teams at Ball Aerospace and starshade concepts advanced through partnerships with Northrop Grumman and Lockheed Martin. High-dispersion spectroscopy efforts link to groups at European Southern Observatory and University of Geneva, while polarimetry projects engage researchers at National Astronomical Observatory of Japan and Kavli Institute for Astronomy and Astrophysics.

Data pipelines and archives coordinated by Space Telescope Science Institute, Mikulski Archive for Space Telescopes, and European Space Agency Science Operations Centre enable population synthesis studies by researchers at Institute for Advanced Study and theoretical frameworks from Princeton University and Caltech. Modeling initiatives encompass atmospheric retrieval techniques championed by teams at University of Exeter and University College London, interior structure models from Carnegie Institution for Science and University of California, Santa Cruz, and habitable zone climate simulations produced at NASA Ames Research Center and National Center for Atmospheric Research. Statistical methods draw on work from Harvard University and Stanford University, while machine learning pipelines are implemented by groups at Google DeepMind collaborators with Massachusetts Institute of Technology.

Priority technologies include next-generation coronagraphs funded through programs at NASA Jet Propulsion Laboratory and European Space Agency, cryogenic detectors advanced at TRW Inc. and Teledyne Technologies, and formation flying demonstrators developed in partnerships involving DARPA and European Space Agency. Flagship mission concepts build on heritage from Hubble Space Telescope, James Webb Space Telescope, and proposals such as Habitable Exoplanet Observatory and Large UV/Optical/IR Surveyor, with technology maturation supported by testbeds at Ames Research Center and facilities at NASA Goddard Space Flight Center. Small-sat and CubeSat initiatives connect to programs at California Institute of Technology and Stanford University while public-private partnerships draw on models used by SpaceX and Blue Origin.

A staged roadmap sequences near-term missions like Transiting Exoplanet Survey Satellite and instruments on Very Large Telescope through mid-term objectives such as Nancy Grace Roman Space Telescope and Roman (space telescope) guest observer campaigns, culminating in late-decade flagship missions comparable to Habitable Exoplanet Observatory concepts and large observatories proposed by European Southern Observatory and Thirty Meter Telescope. Milestones align with community reviews by National Academies of Sciences, Engineering, and Medicine panels, technology readiness assessments at NASA Technology Readiness Level processes, and mission selection cycles administered by European Space Agency and NASA. Funding and workforce development coordinate university programs at Massachusetts Institute of Technology, University of Cambridge, University of California, Berkeley, and national labs including Lawrence Berkeley National Laboratory to meet schedule and science return targets.
