Put to the Test
McCandless and Stewart performed two concurrent spacewalks during the mission, one on February 7 and the second on February 9, for a total duration of 12 hours and 12 minutes. The duo used these extravehicular activities to practice the procedures intended for capturing and repairing a malfunctioning satellite for an upcoming mission. The image above shows McCandless during the first EVA. Two units were tested during the mission, noted by serial numbers 2 and 3.
