<\/a>NASA Television coverage of today\u2019s spacewalk with NASA astronaut Raja Chari and ESA (European Space Agency) astronaut Matthias Maurer is now underway and also is available\u00a0on the\u00a0NASA app<\/a>, the Space Station blog<\/a> and the agency\u2019s\u00a0website<\/a>.<\/p>\n The crew members of Expedition 66 are preparing to exit the\u202fInternational Space Station<\/a>\u2018s Quest airlock for a spacewalk expected to begin about 8:50 a.m. EDT and last approximately six and a half hours.<\/p>\n Chari and Maurer will install hoses on a Radiator Beam Valve Module that routes ammonia through the station\u2019s heat-rejecting radiators to keep systems at the proper temperature. The crew members will also install a power and data cable on the Columbus module\u2019s Bartolomeo science platform, replace an external camera on the station\u2019s truss, and conduct other upgrades to station hardware.<\/p>\n Chari will serve as extravehicular crewmember 1 (EV 1) and will wear a suit with red stripes. Maurer will serve as extravehicular crewmember 2 (EV 2) and will wear an unmarked suit. The spacewalk will be the second of Chari\u2019s career and the first for Maurer. Astronauts Tom Marshburn and Kayla Barron will assist the spacewalkers in and out of their spacesuits and monitor their external activities. Additionally, Barron and Marshburn will be on robotics duty commanding the\u00a0Canadarm2 robotics arm<\/a><\/u>\u00a0to assist during the excursion.<\/p>\n Learn more about station activities by following the space station blog<\/a>, @space_station<\/a> and @ISS_Research<\/a> on Twitter, as well as the ISS Facebook<\/a> and ISS Instagram<\/a> accounts.<\/p>\n Get weekly video highlights at: http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
