Astronauts Steve Swanson and Rick Mastracchio completed a brief spacewalk at the International Space Station Wednesday to replace a failed back up computer. The excursion, which kicked off at 9:20 a.m. EDT, wrapped up at 11:32 a.m. A backup computer had failed 11 April following a routine checkup by the Mission Control team in Houston. While the primary computer continues operating without issue NASA managers ordered Wednesday’s spacewalk to ensure redundancy on critical systems. The computer outage did not pose a risk to the six crew members aboard the space station. (Image Credit: NASA)
