Today's mission was extended and lasted over seven hours to complete the missions that were stopped in the middle of yesterday's spacewalk
Astronauts Chris Cassidy and Tom Mashburn held a complex spacewalk today that was planned in advance to last seven and a half hours and finally ended about twenty minutes less (seven hours and 12 minutes). Their main task is to replace batteries in the oldest solar collector of the International Space Station. This is the mission that Dave Wolff and Chris Cassidy began on the second spacewalk, yesterday, which was interrupted in the middle due to Too high a concentration of carbon dioxide in Cassidy's space suit.
The batteries are near the solar collector in the P6 component, one of the components in the long corridor of the station. They transferred new batteries from the cargo carrier they brought with them on the shuttle to the place where the replacement is performed using the station's robotic arm. Astronaut Julie Fayette and pilot Doug Hurley operated the robotic arm and directed the spacewalkers. After all the battery replacements were complete they moved the carrier back to Endeavour's cargo deck. This maneuver required them to transfer the carrier to the care of Endeavour's robotic arm, which was handled by Hurley and shuttle commander Mark Polanski
