NASA astronauts Christopher J. Cassidy and Thomas H. Marshburn embarked on the fourth of the five spacewalks scheduled for STS-127. During the spacewalk, they finished replacing batteries, a task that they had begun during the 22 July spacewalk but had been unable to complete. Mission Control had terminated the 22 July spacewalk early because of rising levels of carbon dioxide in Cassidy’s spacesuit. During today’s spacewalk, which lasted 7 hours and 30 minutes, Cassidy and Marshburn successfully replaced the last four of the six batteries storing power generated by the ISS’s oldest set of solar arrays. These batteries provided power to the American laboratory Destiny when the station was orbiting in darkness.
