The Expedition 57 crew were allowed to catch a few extra hours of sleep today after a lengthy spacewalk Tuesday by the two cosmonauts on board. They then went to work on a variety of microgravity science and lab maintenance aboard the International Space Station.
Cosmonauts Oleg Kononenko and Sergey Prokopyev performed routine maintenance on their Russian Orlan spacesuits after a seven-hour, 45-minute spacewalk to inspect the Soyuz MS-09 crew ship docked to the station. The duo took detailed photos and captured video of some of the sealant on the outer hull of the Habitation Module used in the repair of a hole discovered inside the vehicle in August.
The other four orbital residents also put in a good night’s sleep after supporting the eighth spacewalk at the station this year. The quartet moved headlong into human research and departure preps after waking up a few hours later than usual today.
Alexander Gerst and Serena Auñón-Chancellor drew their own blood samples today and processed them in the Human Research Facility’s centrifuge. The samples were then coagulated and stowed in a science freezer for later analysis. The Biochemical Profile is a long-running study on astronauts and is providing insight into the human body’s adaptation to living in space.
Gerst is also packing the Soyuz spacecraft that will take him, Auñón-Chancellor and Prokopyev back to Earth Dec. 19. This is the same spaceship that was inspected Tuesday by the two Russian spacewalkers.
The station’s newest astronauts Anne McClain and David Saint-Jacques are still getting used to their new home in space. The pair also went about the day working on a variety of maintenance and research. McClain strapped on an armband monitoring how her body adapts to orbiting Earth 16 times a day after setting up research hardware for two separate experiments. Saint-Jacques deployed over a dozen radiation monitors throughout the station today before some light plumbing work with Gerst in the orbital restroom.
