Small- and medium-class, PI-led Astrophysics missions, as well as Astrophysics missions of opportunity, are selected under the Explorer program, and are managed by the Astrophysics Division.
Sponsored research programs prepare for the next generation of missions through both theoretical research and applied technology investigations.
In order to understand how the Universe has changed from its initial simple state following the Big Bang into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed over time
Discovery is an ongoing program that offers the scientific community the opportunity to assemble a team and design exciting, focused investigations that complement NASA's larger planetary science explorations
The Earth System Science Pathfinder (ESSP) Program is a science-driven Program designed to provide an innovative approach to Earth science research by providing periodic, competitively selected opportunities to accommodate new and emergent scientific priorities
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.
NASA's Exoplanet Exploration Program is leading humankind on a voyage of unprecedented scope and ambition, promising insight into two of our most timeless questions: Where did we come from? Are we alone?
The mission of the Explorers Program is to provide frequent flight opportunities for world-class scientific investigations from space utilizing innovative, streamlined and efficient management approaches within the heliophysics and astrophysics science areas.
