ISS Star Trail Photography By Donald Roy Pettit

On May 25, 2012, Pettit and Kuipers operated the Canadarm2 to grapple the SpaceX Dragon and berth it to the Harmony module. Pettit was the first to enter the unmanned supply ship on May 26, making him the first astronaut in the history of space exploration to successfully enter a commercially-built and operated spacecraft docked in the ISS in orbit.

During Expedition 30, on behalf of NASA in cooperation with Finland-based Rovio Entertainment, creator of the Angry Birds franchise, Pettit also made another video by using an Angry Birds character to explain how physics works in space, including demonstrating trajectories in microgravity by catapulting a Red Bird through the space station.
