<\/a>Two Expedition 65<\/a> cosmonauts are ready for their second spacewalk to continue outfitting Russia\u2019s new science module on Thursday. Meanwhile, another spacewalk is due to take place on Sunday to modify the International Space Station<\/a>\u2019s power system.<\/p>\n Cosmonauts Oleg Novitskiy<\/a> and Pyotr Dubrov<\/a> wrapped up their spacewalk reviews and Orlan spacesuit checks just before lunchtime on Wednesday. The Russian duo is ready to begin Thursday\u2019s spacewalk set to begin at 11 a.m. EDT when they open the hatch on the Poisk airlock<\/a> to the vacuum of space. NASA TV<\/a> will begin its live spacewalk coverage at 10:30 a.m. on the NASA app<\/a> and the agency\u2019s\u00a0website<\/a>.<\/p>\n They will spend about six-and-a-half hours continuing power and ethernet cable connections and installing handrails on the Nauka multipurpose laboratory module<\/a>. The three-time spacewalkers will also complete tasks deferred from the Sept. 3 spacewalk<\/a> including more ethernet cable connections, cable jettisoning and biology experiment installations.<\/p>\n Another spacewalk is scheduled to start Sunday at 8:30 a.m. to install a modification kit on the station\u2019s Port-4 (P4) truss structure<\/a>. Astronauts Akihiko Hoshide<\/a> and Thomas Pesquet<\/a> are preparing for that spacewalk to ready the P4 for the orbiting lab\u2019s third Roll-Out Solar Array due to arrive on a SpaceX Cargo Dragon mission early next year. NASA TV will begin its live coverage at 7 a.m. as the experienced astronauts prepare to exit the U.S. Quest airlock<\/a> in their U.S. spacesuits for a six-and-a-half hour spacewalk.<\/p>\n Meanwhile, science and maintenance continued on the orbiting lab with the crew finding time to work on human research, biology, and combustion. Pesquet from ESA (European Space Agency) studied how astronauts grip objects<\/a> and move their limbs in microgravity while NASA astronaut Shane Kimbrough<\/a> fed rodents and cleaned their habitats during the morning.<\/p>\n Hoshide and NASA Flight Engineer Mark Vande Hei<\/a> worked on a pair of different combustion studies today. Hoshide, the commander from the Japan Aerospace Exploration Agency (JAXA), removed combustion research hardware from the Kibo laboratory module<\/a>\u2018s multipurpose small payload rack. Vande Hei replaced an igniter inside the Combustion Integrated Rack<\/a> for the ACME<\/a> series of space combustion studies.<\/p>\n NASA Flight Engineer Megan McArthur<\/a> focused on orbital plumbing tasks and dismantling air resupply tanks during the morning. After lunch, she turned her attention to unpacking the Cargo Dragon vehicle then joining Vande Hei for a procedures review conference with Sunday\u2019s spacewalkers Hoshide and Pesquet.<\/p>\n Get The Details…<\/a><\/p>\n Mark Garcia <\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n","protected":false},"excerpt":{"rendered":" Two Expedition 65 cosmonauts are ready for their second spacewalk to continue outfitting Russia\u2019s new science module on Thursday.
