Expedition 42 Commander Barry Wilmore and Flight Engineer Terry Virts were back at work Tuesday for more maintenance on the Carbon Dioxide Removal Assembly. The device removes humidity and carbon dioxide from the International Space Station’s environment.
Wilmore later removed and stowed a printed test object, or coupon, from the new 3D printer located in the Destiny lab’s Microgravity Science Glovebox. Italian astronaut Samantha Cristoforetti started the 3D print job earlier in the day.
Fellow cosmonauts Alexander Samokutyaev and Elena Serova partnered up on routine communications maintenance work. They were later joined by their newest crewmate, Anton Shkaplerov, on a chemistry experiment designed to educate Russian students.
