Overview

The Sciences and Exploration Directorate is the largest Earth and space science research organization in the world. Its scientists advance understanding of the Earth and its life-sustaining environment, the Sun, the solar system, and the wider universe beyond. The Directorate is part of Goddard Space Flight Center in Greenbelt, Maryland.

Researchers in the Sciences and Exploration Directorate work with engineers, computer programmers, technologists, and other team members to develop the cutting-edge technology needed for space-based research. Instruments are also deployed on aircraft, balloons, and Earth's surface.

The Directorate's researchers share their findings and data with the scientific community. Education and Public Outreach programs explain the science to students and the general public.

Colleen has served as SED's acting director since February 2014, as well as Goddard’s deputy director for science, operations and performance since July 2012. She has a long and distinguished career with NASA, NOAA, the White House and in academia, having held a variety of leadership posts, including the acting associate administrator, deputy associate administrator, planetary division director in the Science Mission Directorate at NASA Headquarters, and deputy associate administrator at NOAA.

Through her impressive career, Colleen has served as NASA program manager for dozens of missions, built and launched scientific balloon payloads, and worked on robotic vision. She has been instrumental in developing innovative approaches to powering space probes, including in-space propulsion and nuclear power. By gaining White House and congressional approval, she spearheaded the creation of a whole new line of planetary missions called New Frontiers. We are privileged that Colleen brings with her this extensive scientific expertise and breadth of experience as she takes on the vital mission role of director, Sciences and Exploration Directorate.
