New Don Pettit Experiments

During his tour as the science officer of Expedition 6, astronaut Don Pettit spent some of his Saturday mornings conducting a series of scientific experiments. He videotaped some of the experiments and downlinked them to the Mission Control Center at NASA’s Johnson Space Center in Houston, Texas. Pettit’s “Saturday Morning Science” experiments were conducted using ordinary items on the International Space Station. Pettit recently returned to the station as a flight engineer for Expedition 30. And again he is experimenting with everyday objects in microgravity.

NASA and the American Physical Society have begun a partnership to share videos from the space station with science fans around the world. The program is called “Science off the Sphere.” Each episode will end with a question for viewers. APS will review the responses and identify a winner. Pettit will recognize the winner in a later episode.
