  "account": "NASA astronauts Sophie Adenot and Jessica Meir are scheduled to venture outside the International Space Station for a spacewalk on Tuesday, September 1, at 7:30 a.m. EDT. This will be Meir's seventh spacewalk and Adenot's third, marking the 284th spacewalk conducted at the orbital outpost since its inception in 1998. The approximately six-and-a-half hour mission will entail replacing a navigational aid, upgrading a cosmic particle detector, and installing cables to enhance data relay systems.\n\nOn Monday, the astronauts reviewed their procedures, prepared their spacesuits, and organized their tools in the Quest airlock. They also collaborated with NASA flight engineers Anil Menon and Jack Hathaway, studying the Canadarm2 robotic arm techniques required for the spacewalk. Menon will control the Canadarm2, guiding Meir to the designated workstations on the station's starboard truss structure, while Adenot will maneuver on her own.\n\nNASA flight engineer Jack Hathaway will oversee the external activities, ensuring the safety of Adenot and Meir and facilitating the completion of their tasks. Hathaway will also aid the spacewalkers in and out of their spacesuits within the Quest airlock. Meanwhile, the station's cosmonauts, Pyotr Dubrov and Anna Kikina, conducted Roscosmos science and maintenance duties on Monday, testing communications between the Progress 94 cargo craft and the tele-operated robotic unit, or TORU, which could be utilized in the event of automated docking system failure. Dubrov also repaired and tested ethernet cables, while Kikina focused on electronics and ventilation maintenance. Finally, Andrey Fedyaev transferred water into station water tanks and performed a physical fitness test on Zvezda's treadmill.",
