The Expedition 58 crew focused again today on studying head and eye pressure changes astronauts experience while living in space. The crew then went on to more science hardware and life support maintenance aboard the International Space Station.
Flight Engineers Anne McClain and David Saint-Jacques worked throughout Thursday morning researching the upward flow of fluids that occurs inside astronauts’ bodies. The duo conducted eye scans with a variety of devices to measure eye pressure changes caused by these fluid shifts in microgravity.
McClain then spent the afternoon connecting cables and installing parts on the Multi-Purpose Small Payload Rack (MSPR) that houses small experiments in the Kibo lab module. Saint-Jacques replaced electronics gear in the Kubik incubator that enables research on seeds, cells and small animals in the Columbus lab module.
Commander Oleg Kononenko ensured the upkeep of life support gear and other station systems in the Russian segment of the orbital lab. The veteran cosmonaut of three previous Expeditions ended the day exploring how station crew members from around the world interact and learn to live together in space.
