Day 4 of NASA mission to International Space Station

Expedition 16 flight engineer Astronaut Garrett Reisman uses a digital camera to expose a photo of his helmet visor during the mission's first scheduled session of extravehicular activity (EVA) at the International Space Station on March 14, 2008. Also visible in the reflections in the visor are various components of the station, the docked Space Shuttle Endeavour and a blue and white portion of Earth. During the seven-hour and one-minute spacewalk, Reisman and STS-123 mission specialist astronaut Rick Linnehan (out of frame) prepared the Japanese logistics module-pressurized section (JLP) for removal from Space Shuttle Endeavour's payload bay, opened the Centerline Berthing Camera System on top of the Harmony module, removed the Passive Common Berthing Mechanism and installed both the Orbital Replacement Unit (ORU) tool change out mechanisms on the Dexter robotic system, the final element of the station's Mobile Servicing System.
