<\/a>Expedition 68 Flight Engineers Josh Cassada<\/a> and Frank Rubio<\/a> of NASA concluded their spacewalk at 2:21 p.m. EST after 7 hours and 5 minutes.<\/p>\n Cassada and Rubio completed their major objectives for today to install an International Space Station Roll-Out Solar Array (iROSA) and disconnect a cable to ensure the 1B channel can be reactivated. They also completed an additional task to release several bolts for the upcoming iROSA installation on the 4A power channel on the port truss.<\/p>\n It was the 256th spacewalk in support of space station assembly, upgrades and maintenance, and was the second spacewalk for both astronauts. Cassada and Rubio are in the midst of a planned six-month science mission\u00a0living 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\u2019s Artemis<\/a> program.<\/p>\n The next U.S. spacewalk is scheduled for Monday, Dec. 19, to install an iROSA on the 4A power channel on the port truss.\u00a0This will be the fourth iROSAs out of a total six planned for installation. The iROSAs will increase power generation capability by up to 30%, increasing the station\u2019s total available power from 160 kilowatts to up to 215 kilowatts.<\/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.
