U. S. Spacewalk 90 Animation

This animation discusses the upcoming spacewalk in which NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andy Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.
