In this capacity, Smith is responsible for facility infrastructure and maintenance on all major test facilities at Glenn’s Lewis Field Campus. He also is responsible for flight research aircraft, manufacturing facilities, and the environmental management program.
Prior to this appointment, Smith served as director of Space Flight Systems from 2011 through 2020. In that role, he was responsible for the space missions assigned to the center with an annual budget of approximately $425 million. His accomplishments included overseeing the environmental testing and certification of the Orion spacecraft for the Artemis I mission.
Smith has served in a number of leadership positions at NASA, including chief of Glenn’s Systems Engineering and Analysis Division and chief engineer for the NASA Engineering and Safety Center, which provides independent testing and analysis of NASA’s high-risk projects.
Smith began his career in 1983 at Rockwell International as a manufacturing system engineer and later as a production supervisor of military aircraft. Smith joined Glenn in 1987, supporting design and test activities for the development of the International Space Station’s power system. He then served as a launch vehicle mission manager where he was responsible for acquisition, integration and upgrades of launch vehicles.
After completing a two-year program executive assignment at NASA Headquarters, Smith returned to Glenn to serve assignments as chief of the Space Transportation Project Office, chief of the Nuclear Technology and Demonstration Project Office, and chief of Glenn's Crew Exploration Vehicle Project Office, supporting NASA's Space Science and Exploration Programs.
Smith earned his bachelor's degree in industrial and systems engineering from Ohio University, master’s degree in industrial engineering from Cleveland State University, master’s degree in engineering and management from the Massachusetts Institute of Technology, and a certificate in legislative studies from Georgetown University. He is the recipient of numerous NASA awards including NASA’s Significant Achievement Medal and the prestigious Presidential Rank Award for Meritorious Executives.
Assistant General Co-Chair
Mr. Smith has been Chief of the Space Technology Project Office at the NASA John H. Glenn Research Center since 2018. This office manages advanced space technology projects for the GRC Game Changing Development (GCD), Technology Demonstration Missions (TDM) and Small Spacecraft Technology Program (SSTP) projects in the Space Technology Mission Directorate (STMD). Prior to this position he was a project manager for both aeronautics and space technology projects. He began is project management career in 2002 as the deputy project manager for Revolutionary Aeronautics Concepts project. In 2006 he joined the Propulsion and Cryogenics Advanced Development (PCAD) project as the propulsion manager, eventually serving as the deputy project manager from 2007-11. Starting in 2012 was the In-Space Propulsion manager for a variety of space chemical propulsion, nuclear thermal propulsion, and space electric propulsion advanced developments. From 2015-2017 he also served as the portfolio manager for the NASA GRC projects under the GCD program.
Smith began his career at Glenn as an aerospace engineering in 1991 performing experimental and analytical research in rocket propulsion. He has conducted research in both chemical rocket propulsion and gas turbine engines. He been an author or co-author on over 35 technical publications and articles.
Smith earned a bachelor’s and master’s degrees in Aerospace Engineering from the University of Michigan. He has received numerous NASA awards and honors, including a 2020 NASA Outstanding Leadership Medal.
