The astronauts and cosmonauts of Expedition 66 worked throughout Wednesday on U.S. and Russian spacesuits. The orbital residents will also end 2021 working on life science and cargo operations aboard the International Space Station.
Among the 6,500 pounds of cargo delivered aboard the SpaceX Cargo Dragon on Dec. 22 were a U.S. spacesuit and other spacewalking gear. NASA Flight Engineers Kayla Barron and Thomas Marshburn removed the new spacesuit from Dragon on Wednesday then installed communications gear and configured it. The duo also packed an older U.S. spacesuit inside the Cargo Dragon for return to Earth in January. The next U.S. spacewalk is targeted for spring when two astronauts will install a third set of roll-out solar arrays on the orbiting lab.
Russian spacewalks are also planned at the station in 2022 to outfit the Nauka multipurpose laboratory module that arrived in July. Cosmonauts Anton Shkaplerov and Pyotr Dubrov began reviewing procedures today for the upcoming excursions when they will configure Nauka to operate with the rest of the space station. The pair from Roscosmos also started organizing Russian Orlan spacesuit components and spacewalking tools.
The last days of 2021 will see the station crew move headlong into a variety of space biology research. The astronauts have already begun initiating some of the nearly 2,500 pounds of science experiments and research gear delivered in Dragon. Barron and Marshburn will start observing mice on Thursday to understand how microgravity affects the visual function. ESA (European Space Agency) astronaut Matthias Maurer has already started the new Cytoskeleton experiment and will work on it the rest of the week to study how the human cell adapts to weightlessness.
Orbital maintenance is critical to ensure ongoing and safe station operations. NASA Flight Engineers Mark Vande Hei and Raja Chari will focus on that work the rest of the week. Vande Hei will be configuring different research hardware while also assisting the cosmonauts with their Russian spacesuit work. Chari will spend the next few days unpacking the Cargo Dragon and work on station life support and plumbing tasks.
The space station blog is taking a short break until Monday, Jan. 3, as the station’s five astronauts and two cosmonauts orbit Earth into the New Year.
