Expedition 53 is gearing up for three maintenance spacewalks set to take place in October over a period of two weeks. Meanwhile, the six-member crew continued researching today how their long-term missions in space affect their bodies.

Commander Randy Bresnik began unpacking spacewalking gear today ahead of the first of three spacewalks set to begin Oct. 5. He will lead all three spacewalks with NASA astronauts Mark Vande Hei and Joe Acaba. Vande Hei will join him on the first two and Acaba will participate in the final spacewalk. The trio will replace one of the two end effectors on the Canadarm2 robotic arm, lubricate the new component and replace cameras at two locations on the station’s truss.

Flight Engineers Paolo Nespoli and Sergey Ryazanskiy are exploring how living in space impacts their bone marrow. The study takes a look at blood and breath samples with the blood being processed in a centrifuge. Bresnik is also collecting his blood and urine samples that scientists will later analyze for any physiological changes caused by microgravity.
