The Expedition 50 crew is getting ready for Friday morning’s release of Japan’s sixth cargo craft to visit the International Space Station. The station residents are also continuing to explore how their eyes adapt to living in space for months at a time.

The Kounotori HTV-6 resupply ship, from the Japan Aerospace Exploration Agency, is being disconnected from station systems today as it prepares for its departure Friday at 10:30 a.m. EST. Overnight, ground controllers will operate the Canadarm2 and maneuver the HTV-6 away from the Harmony module where it is attached.  NASA TV will broadcast the release and departure activities live beginning at 10 a.m.: https://www.nasa.gov/multimedia/nasatv/index.html

European Space Agency astronaut Thomas Pesquet and Commander Shane Kimbrough of NASA will then command the 57.7-foot-long robotic arm to release Kounotori back into orbit. After the HTV supports science experiments for a week, Japanese flight controllers will command the craft to deorbit on Feb. 5 for a fiery reentry into Earth’s atmosphere.

More Fluid Shifts research took place today as astronauts study the possibility of using a special suit, the Lower Body Negative Pressure (LBNP) suit, to prevent the upward flow of fluids towards the head caused by microgravity. This headward flow may be causing pressure on the back of crew members’ eyes potentially causing damage and affecting vision.

During the afternoon, the crew also participated in ultrasound eye scans. Doctors on the ground assisted the crew to ensure good views of the optic nerve, cornea and back of the eye.
