Ultrasound scans and eye checks aboard the International Space Station today are helping doctors understand how the Expedition 62 crew is adapting to microgravity. Back on Earth, a new crew is in final preparations for its launch next month.
NASA Flight Engineer Jessica Meir spent Tuesday morning on biomedical duty and scanned her leg arteries with an ultrasound device. She also attached electrodes to her neck, thigh and heart for the Vascular Echo study. Flight surgeons on the ground monitor the scans real-time to glimpse a crewmember’s heart and blood vessel health in space.
In the afternoon, Meir joined fellow Flight Engineer Andrew Morgan for eye exams. The duo took turns imaging each other’s eyes using optical coherence tomography gear commonly found in an eye doctor’s office. Eye health in space is important, as some astronauts have reported experiencing vision problems after returning to Earth.
Morgan started the morning swapping out batteries in a device that analyzes the station’s atmosphere. Afterward, he tended to hardware for an experiment that seeks to improve the manufacturing process ...
