Margaret Luce
Heliophysics Division Deputy Director
Margaret (Peg) Luce is the Deputy Director of the Heliophysics Division in the Science Mission Directorate (SMD) at NASA Headquarters in Washington. The Heliophysics Division manages a fleet of missions throughout the solar system dedicated to studying the Sun, heliosphere, and planetary environments as elements of a single interconnected system.
During her time in Heliophysics, Luce has led the charge to put more science in space by establishing a ride-share program to fly more spacecraft on varying rocket sizes resulting from the growing commercial launch market. At the same time, she has led the Heliophysics Division as it expanded its portfolio by leveraging the increasing availability of small spacecraft that are capable of flying in constellations to deliver multi-platform observations that are essential to understanding the science of space weather.
During her tenure in Heliophysics Division leadership, which began in 2015, Luce served twice as the acting division director. She also served recently as the Acting Deputy Associate Administrator for Programs in SMD, where she was responsible for overseeing and assessing SMD’s multibillion-dollar portfolio of over 100 missions.
Luce served as the Deputy Director of NASA’s Earth Science Division from 2008-2015. In that role, she provided overall management of the agency’s entire Earth Science portfolio, including technology development, applied science, research, and development and operation of satellite systems.
Luce joined NASA’s Goddard Space Flight Center in 1987 following six years of engineering experience in the private sector. Throughout her career, Luce has been involved in the development of spaceflight systems to support NASA’s science programs. At Goddard, she served in a number of leadership roles in the Flight Projects Directorate, including project manager for the Earth Observing System Aura Mission, associate director of flight projects for project formulation, and chief of the Advanced Concepts and Formulation Office.
Luce holds a Bachelor of Science in Engineering Mechanics from the University of Wisconsin, Madison, and is the recipient of a NASA Distinguished Service Medal, a NASA Exceptional Service Medal, and a NASA Leadership Award, among others.
