Braun became chief technologist in February 2010 under a two-year intergovernmental personnel agreement with Georgia Tech.
Braun, NASA’s first chief technologist in a decade, was the agency’s principal adviser and advocate on matters concerning agency-wide technology policy and programs.
Braun also led the formulation and implementation of NASA’s Space Technology Program, which develops crosscutting technologies and advanced capabilities to enable NASA’s future space missions.
“He’s done an incredible job, and we’re indebted to him for his exemplary public service,” NASA Administrator Charles Bolden said.
Braun joined Georgia Tech in October 2003, where he led a research and educational program focused on the design of advanced flight systems and technologies for planetary exploration.
Joseph Parrish, the deputy chief technologist, will serve as acting chief technologist.
