ISS - Expedition 59 Mission patch.
April 24, 2019
The Expedition 59 crew is unloading one U.S. cargo ship today and preparing for the arrival of another after it launches from Florida next week. The orbital residents also continued exploring how microgravity impacts the human body and a variety of terrestrial materials.
Astronauts Christina Koch and David Saint-Jacques worked Wednesday afternoon to offload some of the 7,600 pounds of cargo the Cygnus space freighter delivered last week. Saint-Jacques is also training today to capture the SpaceX resupply ship with the Canadarm2 robotic arm when it arrives next Thursday. Dragon will be the sixth spaceship parked at the station and occupy the Harmony module’s Earth-facing port.

The duo also split the day working with a variety of biomedical hardware and research gear to ensure healthy astronauts and successful space research. Koch and Saint-Jacques participated in ultrasound scans for ongoing health checks. Koch then explored the feasibility of manufacturing fiber optic cables in space. Saint-Jacques set up Kubik incubator hardware inside Europe’s Columbus lab module.

NASA Flight Engineers Anne McClain and Nick Hague were back collecting more blood, urine and saliva samples today. The samples are spun in a centrifuge, stowed in a science freezer then analyzed for the long-running Fluid Shifts study. The experiment seeks to understand and prevent the upward flow of body fluids in space that cause head and eye pressure in astronauts.
McClain then studied how living aboard the International Space Station affects her perception and cognition. Hague researched and photographed a variety of coating materials for their thermal protection and optical recognition properties.
