2024 BIG Idea Challenge Co-Chair


Doug Littekenis a Subject Matter Expert (SME) for structural softgoods. He has been at NASA since 2009 and has worked on numerous developmental projects through design, analysis, and testing, including inflatable habitats, inflatable airlocks, softgoods structures, parachutes, flexible electronics, and structural health monitoring. As an SME, he works with the NextSTEP Habitation and Commercial LEO Destination programs to help commercial partners develop expertise in inflatable structures for LEO free-flyer habitats, lunar surface habitats and deep space transit habitats. This work includes leading testing efforts across the agency on inflatable module testing to evaluate their structural performance and failure modes. He also co-wrote a new NASA technical standard, providing guidance on certification requirements for crewed inflatable softgoods structures to be utilized by future programs.

Doug has both a B.S. and M.S. in Mechanical Engineering from the University of Illinois Urbana-Champaign. He is a member of the NASA Engineering and Safety Center (NESC) Structures Technical Discipline Team (TDT) and the American Institute of Aeronautics and Astronautics (AIAA). He has authored 11 technical papers and presented his work at numerous conferences and events. His goal is to advance the use of softgoods in spaceflight and share the capability of this technology across the industry. His efforts towards NASA’s deep space exploration goals will enable a permanent presence on the Moon and help land humans on Mars.
