Science Mission Directorate (SMD)
The overarching role of NASA’s Science Mission Directorate (SMD) is to provide fundamental research on profound science questions using space-based observatories and related assets. The nation’s space research program in Earth and space science is directed and overseen by the Office of the Associate Administrator for SMD. This work is carried out by engaging the external and internal science community to define and prioritize science questions and seeks to expand the frontiers of four broad scientific pursuits: Earth Science, Planetary Science, Heliophysics, and Astrophysics.
SMD provides virtual human access to the farthest reaches of space and time, as well as practical information about changes on planet Earth through sponsored research and a variety of robotic observatory and explorer craft.
