David Strack is a co-founder of Odyssey and a key technical contributor, serving in various roles, including Chief Technical Officer, Program Manager, and strategic advisor. He grew up in Calgary, Canada and moved to the U.S. to attend Texas A&M University where he completed a Bachelor of Science in Aerospace Engineering. Dave’s passion for Human Spaceflight immediately drew him to the NASA Johnson Space Center where he devoted his skills to GN&C and to a specialization in the intricacies of rendezvous and proximity operations for crewed and automated spacecraft. He served in technical leadership roles supporting both large and small subcontractors before starting Odyssey. He helped build Odyssey through its early years and transitioned to a focus on technical advancement of the company and development of various spacecraft and technology programs. Dave has contributed to numerous NASA, international, and commercial spacecraft programs and, in the process, has become a leader in human rated spacecraft GN&C, proximity operations, piloting and docking. He was instrumental in helping NASA and commercial companies safely succeed on the Commercial Orbital Transportation Services program and, more recently, is working to support the success of both the Orion Program and the Commercial Crew Program. In his spare time, David enjoys planning and taking trips to interesting international locations with his family, as well as supporting several organizations that work with underprivileged children in developing countries.

Bryan is the COO of Odyssey. Bryan grew up in Houston in the shadow of Johnson Space Center with strong family ties to Human Spaceflight. He became passionate about making his own contributions during a summer internship working at the JSC Mission Control Center. After his internship, he completed his studies for a BS in Aerospace Engineering at Texas A&M University and immediately started working at NASA for the Propulsion Systems Group supporting Space Shuttle missions as a flight controller. Bryan was both a Space Shuttle flight controller and an International Space Station (ISS) flight controller, ultimately supporting over 40 missions in all phases of flight. He was advanced to leadership positions for both Space Shuttle and ISS before being selected to be a Flight Director in 2000. In the Flight Director role, he supported ISS Expedition and Joint operations for several years before shifting his focus back to the Shuttle program, supporting over a dozen Shuttle missions. Bryan was awarded NASA’s Outstanding Leadership Medal and NASA’s Exceptional Achievement Medal for his leadership on ISS and Space Shuttle missions. At the conclusion of the Shuttle program, Bryan dabbled with a startup rocket propulsion company and also spent time working in Houston’s oil and gas industry. However, Bryan heeded the call of spaceflight once again, and returned to his original passion. He is thrilled to be part of the Odyssey Space Research leadership team where he has the opportunity to continue contributing to America’s Human and uncrewed spaceflight programs. When not participating in our space program, Bryan enjoys spending time with his family, traveling and supporting various community and church activities.
