David Wolf

Dr. Wolf served as chief of the Astronaut Office Extravehicular Activity (EVA) Branch for much of the International Space Station (ISS) assembly. He led a team responsible for the development, test and execution of spacewalks from the ISS and space shuttle. This team plays a critical role for ISS assembly, maintenance and repair; requiring innovations to extend EVA capability in the areas of hardware, techniques and human performance. Dr. Wolf has logged 168 days, 12 hours, 56 minutes and 04 seconds in space over four separate missions, including a long-duration mission (128 days) on the Russian MIR space station, which was trained and conducted completely in the Russian language. He has conducted a total of seven spacewalks, using both the American and Russian spacesuits, and has logged 47 hours and 05 minutes of extravehicular activity. He is an active public speaker and is called on to represent NASA in a wide variety of venues to communicate the experience and importance of human space flight.

In 1983, Dr. Wolf joined the Medical Sciences Division, Johnson Space Center, Houston, Texas. He was responsible for the development of the American Flight Echocardiograph, which is used in space for investigating cardiovascular physiology in microgravity. This work required synthesis of spacecraft avionics integration, human physiology and space operations to acquire fundamental cardiovascular data for human space exploration and reveal new Earth-based physiological principles. On completion, he was assigned as Chief Engineer for design of the Space Station Medical Facility, now operational on orbit. This work pioneered concepts in telemedicine, medical informatics and bioinstrumentation. In 1986, he became Chief Engineer (and, later, Program Manager) of the “Space Bioreactor,” a biotechnology-based tissue engineering and cancer research program. This team, under Dr. Wolf’s leadership, achieved the development of state of the art tissue engineering systems now widely used for both commercial and research purposes on Earth. Dr. Wolf fostered the successful technology transfer to private industry and to academic laboratory applications. Special skills developed include real-time computer process control, communications, power systems, bioprocessing, fluid dynamics, aerospace physiology and aerospace medicine. In these roles, Dr. Wolf was responsible for technical and multidisciplinary team leadership, a multimillion dollar budget, systems design, safety (electrical and biological) and spacecraft integration. This “on schedule” program is now a core biotechnology research facility on the ISS.
