Expedition 56 crew members are transferring cargo in and out of U.S. and Russian cargo ships today. Two astronauts are also planning to release a U.S. resupply ship on Sunday ending its mission at the International Space Station.

Astronauts Serena Auñón-Chancellor and Alexander Gerst were back inside the SpaceX Dragon today unloading science gear and station hardware from inside the space freighter. Cosmonauts Oleg Artemyev and Sergey Prokopyev of Roscosmos continued unloading the nearly three tons of crew supplies and station hardware delivered Monday aboard the new Progress 70 cargo craft.

The Cygnus resupply ship will complete its stay at the orbital Sunday at 8:35 a.m. EDT after 52 days attached to the Unity module. Gerst of ESA (European Space Agency) will use the Canadarm2 robotic arm to release Cygnus back into Earth orbit backed up by Auñón-Chancellor of NASA. Cygnus will remain in orbit until July 30 supporting engineering activities before it is deorbited to burn up harmlessly over the Pacific Ocean.

Space research aboard the orbital lab is always ongoing as the crew explored a variety of life science today. The space residents explored how microgravity impacts fertility, algae production and the gastrointestinal system. The crew also completed routine eye checks with an ultrasound device Wednesday morning to maintain good vision during spaceflight.
