In this new position, Lyles will lead the propulsion effort that
will eventually launch a second generation reusable launch vehicle and
return it to a landing site on Earth. Technology development will include
reusable propulsion systems involving main engines, main propulsion
systems and auxiliary propulsion systems. The Propulsion Project Office
also will develop propulsion systems for emergency crew escape systems.
Lyles most recently was manager of the Advanced Space Transportation
Program Office at Marshall, responsible for developing NASA’s space
transportation and propulsion “roadmaps” for the next 25 years.
Since coming to NASA in 1976, Lyles has held several
propulsion-related positions, including chief engineer for the Space
Shuttle Main Engine in the Space Transportation Systems Chief Engineers
Office; chief of the Canoga Park Resident Office for the Space Shuttle
Main Engine Project Office; and division chief of the Propulsion Systems
Division of Marshall’s Propulsion Laboratory.
He earned his bachelor’s degree in mechanical engineering at the
University of Alabama in Tuscaloosa.
Lyles is married to the former Diane Miller and has four children.
NASA’s Space Launch Initiative is the key to opening the space
frontier for continued scientific exploration and economic expansion – by
making space flight affordable and safe for both the government and
private industry.
Marshall Center leads NASA’s efforts in development of space
transportation and propulsion systems and technologies.
