Maintenance and experiment work continued on Wednesday for the Expedition 43 crew.
NASA astronaut Terry Virt spent the second consecutive day replacing components inside one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin. Virts also did some preparatory work on a payload rack for a cellular biology experiment scheduled to launch on the next SpaceX mission.
ESA astronaut Samantha Cristoforetti continued the Triplelux-A experiment which aims to gain a better understanding of immune suppression in spaceflight. She also Russian cosmonaut Anton Shkaplerov in a checkout of the Sokol launch and entry suits that she, Shkaplerov and Virts will wear when they return to Earth next week.
