Daniel (Dan) L. Dumbacher is a Professor of Engineering Practice in the School of Aeronautics and Astronautics at Purdue University. He teaches courses in systems thinking, systems engineering, and space policy.
Prior to joining the faculty at Purdue, Mr. Dumbacher served as the Deputy Associate Administrator, Exploration Systems Development Division, for the Human Exploration and Operations Mission Directorate at NASA Headquarters. In that capacity, he provided leadership and management as the Program Director for Exploration Systems Development encompassing the Space Launch System, Orion, and Ground Systems Development and Operations (GSDO) development and integration efforts. He led a team of over 5000 people spanning all NASA Centers and Industry. He was responsible for a $3B annual budget.
From 2007-2010, Mr. Dumbacher served as the Director of the Engineering Directorate at NASA’s Marshall Space Flight Center. Appointed to the position in May 2007, Mr. Dumbacher led an organization of 1,400 civil service and 1,200 support contractor employees. Under his leadership, the Engineering Directorate supported the Space Shuttle propulsion elements, design and development of the Ares launch vehicles, operation of NASA’s Payload Operations Center—the command post for scientific research activities on board the International Space Station, and supported all Marshall Space Flight Center International Space Station and Science missions.
Previously, Mr. Dumbacher was Deputy Director of the Ares Projects Office and, prior to that, was Deputy Director for Product Assurance in the Safety and Mission Assurance Office, focusing on Space Shuttle return-to-flight efforts. He served as the Deputy Manager of the Space Launch Initiative Program and as the Program Manager of the Second Generation Reusable Launch Vehicle Program. He was the Deputy Manager of the X-33 Flight Vehicle Program and Manager of the Delta Clipper-Experimental Advanced Flight Vehicle Project. He also served as Assistant Manger of the Space Shuttle Main Engine Project and Manager of the Technology Test Bed Project, overseeing hot-fire testing of large liquid propulsion engines.
Mr. Dumbacher has significant experience with the DoD space community. In 2003 and 2004 Mr. Dumbacher served as Manager of the X-37 Flight Demonstrator, including joint program proposal evaluation with the Air Force and transitioning the X-37 project to the U.S. Air Force. In 2002 Mr. Dumbacher was the NASA co-lead on the 120 Day Study with the Air Force on launch vehicle development and systems technology joint efforts. In addition, as part of his duties throughout his career, Mr. Dumbacher has participated with the U.S. Air Force on technology joint projects and briefing senior
Mr. Dumbacher joined NASA in 1979 as a summer student performing thermal analysis on Spacelab missions, and in the summer of 1980 worked on turbomachinery and systems analysis of the Space Shuttle Main Engines. Following graduation from Purdue in 1981, he returned to NASA in the Liquid Propulsion Systems Branch performing systems analysis on the Space Shuttle Main Engine ground test and flight engines. In 1985 he ventured into missile vehicle integration work on the Strategic Defense Initiative for Teledyne-Brown Engineering. He returned to NASA in 1987 as the Chief Engineer for the Alternate Turbopump Development Project.
During his career, he has received numerous awards and honors. He was awarded the W.A. Gustafson Teaching Award at Purdue in 2015 and was named an AIAA Associate Fellow in 2016. In 2014, he was awarded the coveted Silver Snoopy Award, and the NASA Distinguished Service Medal. In 2007, he was awarded the Presidential Rank Award for Meritorious service. In 2003, Purdue University recognized him with the Outstanding Mechanical Engineer award. He received the NASA Exceptional Achievement Medal in 2002 for accomplishments related to NASA’s Space Launch Initiative Program, and in 1997 for his work on the DC-XA Project. In 1996, he was honored with a Marshall Director’s Commendation for accomplishing two flight tests within 26 hours in the DC-XA Project flight test series.
Mr. Dumbacher earned a bachelor’s degree in mechanical engineering from Purdue University in 1981 and a Master’s in Business Administration from the University of Alabama in Huntsville in 1984. He has completed the Senior Managers in Government study program at Harvard University. Mr. Dumbacher has authored several papers on liquid propulsion technologies, space transportation systems development, and systems engineering.
Mr. Dumbacher is a native of Indianapolis, IN and attended Bishop Chatard High School. He and his wife Lee have three grown children: Erin, an Elliott School graduate in International Affairs from The George Washington University and Johns Hopkins Shcool for Advanced International Studies, residing in Washington, D.C., Dana, a 2011 graduate of Marquette University, and a Masters degree in Public Policy at the University of Minnesota, and Brad, a recent graduate of Marquette University and member of their Men’s basketball staff, attending the University of Georgia Law School.
