ISS018-E-039022 (10 March 2009) --- Astronaut Michael Fincke, Expedition 18 commander, participates in a session of extravehicular activity (EVA) to perform maintenance on the International Space Station. During the 4-hour, 49-minute spacewalk, Fincke and cosmonaut Yury Lonchakov (out of frame) reinstalled the Exposing Specimens of Organic and Biological Materials to Open Space (Expose-R) experiment on the universal science platform mounted to the exterior of the Zvezda Service Module. The spacewalkers also removed straps, or tape, from the area of the docking target on the Pirs airlock and docking compartment. The tape was removed to ensure it does not get in the way during the arrival of visiting Soyuz or Progress spacecraft.
