Two veteran International Space Station crew members will swap command of the orbiting lab during the traditional Change of Command Ceremony this afternoon.

The six-member space station crew will gather together at 4:15 p.m. EDT when Expedition 63 Commander Chris Cassidy of NASA ceremonially hands control of the station to Expedition 64 cosmonaut Sergey Ryzhikov of Roscosmos. Ryzhikov will officially begin his command on Wednesday when Cassidy and Flight Engineers Anatoly Ivanishin and Ivan Vagner undock from the station at 7:32 p.m. inside the Soyuz MS-16 crew ship. All the activities will be broadcast live on NASA TV.

Meanwhile, science and maintenance activities are moving right along inside the space station. Cassidy and NASA Flight Engineer Kate Rubins both had time set aside today collecting blood, saliva and urine for stowage and later analysis. Rubins then checked out research hardware and plumbing gear before familiarizing herself with station systems.

Ryzhikov and Vagner spent a couple of hours swabbing surfaces in the Russian segment of the station collecting microbial samples and placing them in petri dishes for incubation and analysis. Vagner also joined Ivanishin to test the Lower Body Negative Pressure suit for its ability counteract some adverse effects of long-duration spaceflight and prepare the duo for the return to Earth’s gravity.

New space flyer Sergey Kud-Sverchkov synchronized cameras with clocks on station laptop computers and worked on Russian plumbing tasks. The cosmonaut also is getting used to living and working in space for the first time.
