NASA Astronaut Donald R. Pettit recently completed his first space flight as NASA ISS Science Officer aboard the International Space Station, logging over 161 days in space, including more than 13 EVA (spacewalk) hours. During its more than 5 months aboard the International Space Station, the crew worked with numerous U.S. and Russian science experiments. Pettit and the mission commander Ken Bowersox performed two EVAs to continue the external outfitting of the orbital outpost. Pettit was selected by NASA in April 1996, and he reported to the Johnson Space Center in August 1996. Co-sponsored by the Rice Space Institute and the James A. Baker III Institute for Public Policy, Pettit shares a fascinating presentation of the International Space Station.
