Crew Gears Up for Spacewalk, Scans Eyes and Practices Medical Emergency

The Expedition 60 crew is gearing up for an upcoming spacewalk to prepare the International Space Station for more commercial crew missions. Biomedical science also took up a portion of the astronauts’ day as they help researchers understand what happens to the human body in microgravity.

NASA astronauts Nick Hague and Andrew Morgan are reviewing their tasks planned for Aug. 21 when they conduct the fifth spacewalk of the year at the orbiting lab. The duo will take about six-and-a-half hours to install the International Docking Adapter-3 (IDA-3) on top of the Harmony module. The IDA-3, delivered inside the Dragon cargo craft’s trunk, will be the second port at the station designed to receive the new Boeing and SpaceX crew ships.

Flight Engineers Christina Koch and Luca Parmitano are helping the spacewalkers get ready for the upcoming excursion. They are configuring spacesuit components today and will continue assisting the pair before, during and after the next spacewalk.

Morgan first joined Koch and Parmitano during the morning for ultrasound eye exams. Koch took charge of the eye scans in the Columbus lab module with real-time inputs from doctors on the ground. She observed her crewmates’ retina, cornea, lens and optic nerve to maintain eye health in space.

Koch and Parmitano later split up feeding the station’s mice and cleaning their habitats in the Destiny laboratory module. Observing the rodents, which are genetically similar to humans, in the weightless environment of microgravity gives scientists critical therapeutic insights that can benefit Earthlings and astronauts.

The most recent trio to arrive at the station gathered at the end of the day to train for a medical emergency. Morgan, Parmitano and cosmonaut Alexander Skvortsov practiced cardiopulmonary resuscitation (CPR), checked out medical gear and reviewed emergency communications.
