<\/a><\/figure>On Tuesday, Aug. 25, NASA flight engineer Anil Menon<\/a> and ESA (European Space Agency) flight engineer Sophie Adenot will conduct a spacewalk to finish replacing the space\u2011to\u2011ground antenna on the International Space Station<\/a>. The pair began the work on Aug. 18<\/a>.<\/p>\n Menon will ride the Canadarm2 robotic arm<\/a> to retrieve a spare antenna that Adenot will release from an external platform. Together, they will install the antenna on the Z1 truss segment above the station\u2019s Unity module<\/a>. The astronauts then will make the precise electrical and data connections needed to activate the spare antenna for high\u2011speed transmissions with mission control.\u00a0<\/p>\n If time allows, Menon and Adenot will attempt a get\u2011ahead task to replace a retroreflector on the forward port of the Harmony module<\/a>, which improves navigation data for visiting spacecraft. Menon will serve as spacewalk crew member 1 and will wear a suit with red stripes. Adenot will serve as crew member 2 and will wear an unmarked suit. NASA\u2019s live spacewalk coverage<\/a> on Aug. 25 begins at 7 a.m. EDT. The spacewalk is expected to start at about 8:35 a.m. and last roughly six and a half hours.<\/p>\n NASA also is planning a fourth spacewalk on Tuesday, Sept. 1, to connect power channel cables and data relay systems as part of ongoing maintenance. However, the replacement of the retroreflector would become the primary task if it is not completed on Aug. 25. The agency will make a decision on whether the early September spacewalk is needed following installation of the space-to-ground antenna.<\/p>\n Inside station on Thursday, Adenot and Menon were joined by station commander Jessica Meir and flight engineer Jack Hathaway, both NASA astronauts, for spacewalk procedure reviews throughout the day. Meir and Hathway will help the spacewalkers in and out of their spacesuits next week. Meir will also monitor the spacewalkers and assist Hathaway as he operates the Canadarm2 with Menon attached. The four astronauts also called down to mission controllers at the end of their shift on Thursday to discuss spacewalk procedures and robotics operations.<\/p>\n The astronauts still had time for research and lab maintenance on Thursday. Meir participated in a relaxation study<\/a> to help reduce stress and improve sleep during a long-duration space mission. Hathaway photographed 3D colloidal crystal samples growing for a space manufacturing investigation<\/a>. Menon and Adenot spent their extra time on light maintenance duties servicing life support and communications systems. <\/p>\n The three Expedition75 cosmonauts stayed focused on their station research and lap upkeep tasks for Roscosmos. Flight engineer Anna Kikina jogged on the Zvezda service module<\/a>\u2019s treadmill as electrodes measured her heart rate for a regularly scheduled fitness assessment. Afterward, she assisted flight engineer Pyotr Dubrov as he installed Earth observation gear<\/a> to automatically capture visible and near-infrared photography of rivers, lakes, and mountains throughout Europe and Asia. Flight engineer Andrey Fedyaev spent his shift on orbital plumbing and ventilation maintenance.<\/p>\n Learn more about station activities by following the <\/em>space station blog<\/em><\/a>, <\/em>@space_station<\/em><\/a> on X, as well as the <\/em>ISS Facebook<\/em><\/a> and <\/em>ISS Instagram<\/em><\/a> accounts.<\/em><\/p>\n Get the latest from NASA delivered every week. <\/em>Subscribe here<\/em><\/a>.<\/em><\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a><\/p>\n Mark A.
