Science and Technology Programs

  • Astrophysics Explorers

    The Astrophysics Explorers program includes opportunities for innovative science and fill the scientific gaps between the larger missions. Small PI-led astrophysics missions are selected under the Explorer program, and are managed by the Astrophysics Division.

  • Astrophysics Research

  • Cosmic Origins

    To observe the birth of the earliest galaxies, the formation of stars and their planetary systems in the Milky Way and other galaxies, and the origins of the elements necessary for life. Cosmic Origins tells the story of the processes that transpired from the Big Bang to the modern Universe. "How did we get here?"

  • Discovery

    The Discovery Program conducts focused investigations that complement NASA's larger Planetary Science goals by launching smaller missions using fewer resources and shorter development times.

  • Earth Systematic Missions

    The Earth Systematic Missions (ESM) Program includes a broad range of multi-disciplinary science investigations aimed at developing a scientific understanding of the Earth system and its response to natural and human-induced forces. Understanding these forces will help in determining how to mitigate them, appropriately and where possible, to avoid climate changes.

  • Earth System Science Pathfinder

    The Earth System Science Pathfinder (ESSP) Program addresses unique, specific, highly-focused mission requirements in Earth science research.

  • Exoplanet Exploration

    NASA's Exoplanet Exploration Program represents a voyage of unprecedented scope and ambition, promising insight into humankind's most timeless question: Are we alone?

  • Explorers

    The mission of the Explorer program is to provide frequent flight opportunities for scientific investigations from space.


    The Geostationary Operational Environmental Satellite (GOES)/ Polar Operational Environmental Satellite (POES) program is a key element in National Weather Service (NWS) operations.

  • Heliophysics Explorers

    This program is managed by the Heliophysics Division and solicits missions for both Heliophysics and Astrophysics.
