Expedition 62 Commander Oleg Skripochka of Roscosmos, in the middle, is flanked by NASA Flight Engineers Andrew Morgan and Jessica Meir inside U.S. Destiny laboratory module.
The Expedition 62 crew focused on a variety of human research and space biology studies aboard the International Space Station today. Back on Earth, three new crewmembers are in training in Russia before their mission begins in April.
Microgravity shifts the flow of body fluids, such as blood and water, which accumulate in an astronaut’s head creating pressure in the cranium and on the eyes. Doctors are continuously studying this phenomenon to counteract the effects and keep long-term space crews healthy.
In preparation for upcoming operations with the ongoing Fluid Shifts study, NASA astronaut Andrew Morgan collected medical hardware, such as an ultrasound device, sensors and cables. He transferred the research gear to the Russian segment, where they will be used to test a specialized body suit that draws fluids toward the lower body expanding veins and tissues.
Morgan then moved on to a Japanese study that looks at how weightlessness affects genetic expression in mice. Results may inform future therapies that keep crews safe in space and prevent muscle atrophy conditions on Earth.
