U.S. Spacewalk 90 Animation

An animation of U.S. Spacewalk 90 scheduled for Thursday, June 13, when NASA astronauts Tracy C. Dyson and Matt Dominick will exit the station’s Quest airlock to complete removal of a faulty electronics box, called a radio frequency group, from a communications antenna on the starboard truss of the space station. The pair also will collect samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory.
