Two NASA astronauts are preparing for a spacewalk on Tuesday to replace a malfunctioning antenna system on the International Space Station.
Flight engineers Thomas Marshburn and Kayla Barron will leave the orbital laboratory after setting up their US spacesuits on battery power at 7:10 am EST tomorrow, marking the beginning of their spacewalk.
On Monday, three of their expedition 66 flight engineers joined the duo to collect tools and review the procedures for the planned six and a half hour spacewalk. NASA astronaut Raja Chari worked with Marshburn and Barron to collect and organize ropes, cameras, and pistol grip tools. Subsequently, the three astronauts joined NASA astronaut Mark Vande Hei and ESA (European Space Agency) astronaut Matthias Maurer to participate in a program meeting with ground-based spacewalk experts.
Chari and Vande Hei will be on duty throughout Tuesday, monitoring the two astronauts during the spacewalk and helping them get in and out of the spacesuit. Maurer will assist spacewalkers on the Port-1 truss construction site under the control of the Canadaarm2 robotic arm. NASA TV began live broadcasting on the agency’s website and NASA app at 5:30 am on Tuesday.
The two astronauts of the station, flight engineer Pyotr Dubrov and commander Anton Shkaplerov, spent various space research and maintenance tasks in the Russian part of the orbital laboratory. On Friday, after the Prihar module was docked, Dubrov photographed the status of the Nauka multifunctional laboratory module. Shkaplerov replaced the life support hardware and began to unpack the cargo from the newly arrived Prichal docking port.
ISS HAM: The crew completed the ISS HAM pass with Colegio Pumahue Temuco of Temuco, Chile. The school belongs to the Cognita Schools International Group and is a certified Cambridge International School. ISS Ham Radio provides opportunities for students, teachers, parents and other members of the community to participate in and educate students in science, technology, engineering, and mathematics by providing a means of communication between astronauts and ground-based HAM radio devices.
Storage: The crew collects urine and blood. The Repository supports scientific discoveries that contribute to our basic knowledge in the field of human physiological changes and adaptation to the microgravity environment, and provide a unique opportunity to study the longitudinal changes in human physiology that span many tasks.
Extravehicular activity (EVA) preparation: Today, USOS staff continue to prepare for the upcoming EVA, which will replace the S-band antenna support assembly (SASA) on the port 1 truss. SASA is an antenna component that provides S-band communication. The final preparations include preparing the EMU and the airlock for EVA and suiting. Before the meeting with ground experts, the crew also printed EVA-specific cufflink pages, configured tools, and reviewed procedures. US EVA #78 is scheduled to be held on Tuesday, November 30, and the joint airlock exit occurred at about 6:40 AM Central Standard Time in the United States.
Waste and Sanitary Compartment (WHC) Flight Maintenance (IFM): As part of regular preventive maintenance, the crew performed manual WHC flushing tank filling. By using the post-flight analysis bag to capture any pressure release (also known as hiccups), they decompress the flush tank and water valve block to protect the dosing pump. This pump is essential because it is filled with the pre-treatment agent required for the correct recovery of waste urine.
