Italian astronaut Samantha Cristoforetti and Commander Barry Wilmore began fan pump separator replacement work Tuesday on a U.S. spacesuit. Cristoforetti started her day with medical science collecting saliva and urine samples for stowage in a science freezer. NASA astronaut Terry Virts worked on a variety of science including updating Ultrasound scanner software, checking a botany experiment and participating in an eye exam.
Veteran cosmonauts Alexander Samokutyaev and Anton Shkaplerov started their day in the Zarya cargo module installing overlay sheet on interior panels. Russia’s first female cosmonaut to join a station crew, Elena Serova, conducted a photographic inspection on windows in the station’s Russian segment.
The cosmonaut trio also worked on their task list of Russian experiments studying such things as chemical reactions in Earth’s atmosphere, detecting micrometeoroid impacts and a crew member’s sensory adaptation to long-term microgravity.
Meantime, SpaceX is counting down to the launch of its Dragon commercial cargo craft Dec. 16 at 1:31 p.m. EST. NASA TV will provide live coverage of science, technology and pre-launch briefings including the launch itself.
