NASA astronauts Thomas Marshburn and Kayla Barron are reviewing the procedures they will use during Thursday’s spacewalk. The duo will exit the International Space Station after setting their U.S. spacesuits to battery power at 6:15 a.m. EST signifying the start of their spacewalk. photographed the condition of electronics gear that supports commercial spaceflight operations.

NASA Astronauts Replace Antenna System Ending Spacewalk

NASA astronauts Thomas Marshburn and Kayla Barron concluded the first Expedition 66 spacewalk at 12:47 p.m. EST, after 6 hours and 32 minutes.

Marshburn and Barron successfully installed an S-band Antenna Subassembly (SASA) on the Port-1 truss structure and stowed the failed antenna. Additionally, the pair completed get-ahead tasks on the Port-4 truss structure, including resetting the torque on a set of bolts.

This was the fifth spacewalk for Marshburn, the first for Barron, and the 13th spacewalk at the International Space Station this year. Marshburn has now spent a total of 31 hours and one minute spacewalking, and Barron’s spacewalking time is now 6 hours and 32 minutes. Space station crew members have now spent a total of 64 days, 12 hours, and 26 minutes working outside the station conducting 245 spacewalks in support of assembly and maintenance of the orbiting laboratory.

NASA Spacewalk to Replace Space Station Antenna

Earlier this month, the International Space Station surpassed its 21-year milestone of continuous human presence, providing opportunities for unique research and technological demonstrations that help prepare for long-duration missions to the Moon and Mars and also improve life on Earth. During that time, 249 people from 19 countries have visited the orbiting laboratory, which has hosted nearly 3,000 research investigations from researchers in 108 countries and areas.
