NASA astronauts Jasmin Moghbeli and Loral O’Hara concluded their spacewalk today at 2:47 p.m. EST after 6 hours and 42 minutes. Their spacewalk began at 8:05 a.m. Moghbeli, designated extravehicular crew member 1 (EV1), was wearing a suit with red stripes. O’Hara, designated extravehicular crew member 2 (EV 2), was in an unmarked suit.
Moghbeli and O’Hara were able to complete one of the spacewalk’s two major objectives, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station. Mission Control told the station crew that the solar array was functioning well after the bearing replacement. Spacewalkers also removed a handling bar fixture to prepare for future installation of a roll-out solar array and properly configured a cable that was previously interfering with an external camera.
Deferred Tasks and Tool Bag Incident
The astronauts had planned to remove and stow a communications electronics box called the Radio Frequency Group, but there was not enough time during the spacewalk to complete the work. The duo lifted some multilayer insulation to make a better assessment of how to approach the job before replacing the insulation and deferring the task to a future spacewalk.

During the activity, one tool bag was inadvertently lost. Flight controllers spotted the tool bag using external station cameras. The tools were not needed for the remainder of the spacewalk. Mission Control analyzed the bag’s trajectory and determined that risk of recontacting the station is low and that the onboard crew and space station are safe with no action required.
Upcoming Missions and Resupply Launch
Moghbeli and O’Hara are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.
NASA and SpaceX are now targeting 9:16 p.m. EST on Tuesday, November 7, for the launch of the company’s 29th commercial resupply services mission to the International Space Station. The additional time allows for completion of final prelaunch processing ahead of liftoff of the SpaceX Falcon 9 rocket and cargo Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
NASA Television coverage of launch will begin at 8:45 p.m. The spacecraft, which is carrying approximately 6,500 pounds of supplies, research, and hardware will arrive at the space station shortly before 12 p.m. Thursday, November 9, with coverage beginning at 10:15 a.m.
