Two NASA astronauts are preparing for a spacewalk on Tuesday (November 30, 2021) to replace a faulty antenna system on the International Space Station. Flight Engineers Thomas Marshburn and Kayla Barron will exit the orbiting lab today after setting their U.S. spacesuits to battery power at 7:10 a.m. EST signifying the start of their spacewalk.

The duo was joined on Monday by three of their fellow Expedition 66 flight engineers collecting tools and reviewing procedures planned for the six-and-a-half-hour spacewalk. NASA astronaut Raja Chari partnered with Marshburn and Barron gathering and organizing tethers, cameras, and pistol grip tools. The three astronauts then joined NASA astronaut Mark Vande Hei and ESA (European Space Agency) astronaut Matthias Maurer for a procedures conference with spacewalk specialists on the ground.

Chari and Vande Hei will be on duty throughout Tuesday monitoring the two astronauts during the spacewalk and helping them in and out of their spacesuits. Maurer will be at the controls of the Canadarm2 robotic arm assisting the spacewalkers at the Port-1 truss structure worksite. NASA TV begins its live coverage on Tuesday at 5:30 a.m. on the agency’s website, and the NASA app.

The station’s two cosmonauts, Flight Engineer Pyotr Dubrov and Commander Anton Shkaplerov, spent their day on a variety of space research and maintenance tasks in the orbiting lab’s Russian segment. Dubrov photographed the condition of the Nauka multipurpose laboratory module following the Prichal module’s docking on Friday. Shkaplerov swapped out life support hardware and began unpacking cargo from the newly arrived Prichal docking port.
