Expedition Six NASA ISS Science Officer Don Pettit used his time while living aboard the International Space Station to shed the light of science on a variety of subjects. Saturdays aboard the station are usually free time for crewmembers, who often take the opportunity to do some housecleaning and then look out the window, read a book or write a letter.

Pettit spent some of his Saturday mornings conducting his own series of scientific experiments, and he videotaped some of them and downlinked them to the Mission Control Center in Houston, Texas.

On this page are some of the videotaped experiments. The scrollable menu below the video player lists all videos currently available.  Just scroll, click and enjoy.
