<\/a>NASA astronauts\u00a0Thomas Marshburn<\/a>\u00a0and\u00a0Kayla Barron<\/a> concluded the first Expedition 66<\/a> spacewalk at 12:47 p.m. EST, after 6 hours and 32 minutes.<\/p>\n 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.<\/p>\n This was the fifth spacewalk for Marshburn, the first for Barron, and the 13th spacewalk at the International Space Station<\/a> this year. Marshburn has now spent a total of 31 hours and one minute spacewalking, and Barron\u2019s 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<\/a> in support of assembly and maintenance of the orbiting laboratory.<\/p>\n Earlier this month, the International Space Station surpassed its\u00a021-year milestone<\/a>\u00a0of 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\u00a0research investigations<\/a>\u00a0from researchers in 108 countries and areas.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
