The first spacewalk is scheduled to begin at 10 a m and last about six hours with NASA TV coverage beginning at 8:30 a m

On Oct 12, O’Hara and Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit U S spacewalk 89 will be the first spacewalk for both crew members

On Oct 20, O’Hara and Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna on the starboard truss of the station and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2 U S spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara

The second spacewalk will begin at 7:30 a m and last approximately six and a half hours with NASA TV coverage beginning at 6 a m
