TheScience Mission Directorate (SMD) of theNational Aeronautics and Space Administration (NASA) is one of the six directorates that constitute NASA. Its responsibility is to define and direct research into scientific questions of interest, sharing data acquired by NASA missions with the broader scientific community, sponsoring scientific research, and developing satellites and spacecraft in conjunction with other directorates and with partner organizations for scientific missions.
The Science Mission Directorate also sponsors research that both enables, and is enabled by, NASA's exploration activities. The SMD portfolio is contributing to NASA's achievement of the Vision for Space Exploration by striving to:
Understand thehistory of Mars and theformation of the Solar System. By understanding the formation of diverseterrestrial planets (with atmospheres) in the Solar System, researchers learn more about Earth's future and the most promising opportunities for habitation beyond our planet. For example, differences in the impacts of collisional processes on Earth, the Moon, and Mars can provide clues about differences in origin and evolution of each of these bodies.
Search forEarth-like planets andhabitable environments around other stars. SMD pursues multiple research strategies with the goal of developing effective astronomically-detectable signatures of biological processes. The study of the Earth-Sun system may help researchers identify atmosphericbiosignatures that distinguish Earth-like (and potentially habitable) planets around nearby stars. An understanding of theorigin of life and the time evolution of the atmosphere on Earth may reveal likely signatures of life onextrasolar planets.
Explore the Solar System for scientific purposes while supporting safe robotic and human exploration of space. For example, large-scalecoronal mass ejections from the Sun can cause potentially lethal consequences for improperly shielded human flight systems, as well as some types of robotic systems. SMD's pursuit of interdisciplinary scientific research focus areas will help predict potentially harmful conditions in space and protect NASA's robotic and human explorers.
Nicola Fox is the Associate Administrator for the Science Mission Directorate beginning February 27, 2023.[1] Recent Associate Administrators for the SMD includeEdward J. Weiler (1998–2004, 2008–2011),Mary L. Cleave (2004–2005),Alan Stern (2007–2008),John M. Grunsfeld (2012–2016), andThomas Zurbuchen (2016-2022). Stern resigned 25 March 2008, to be effective 11 April, over disagreements with AdministratorMichael D. Griffin.[2]
