Crew Tests Lower Body Suit to Protect Vision; Soyuz Rocket Rolls Out Wednesday










ISS - Expedition 52 Mission patch.

One of the effects of living in space is the tendency of fluids to shift upward towards an astronaut’s head. This results in the common “puffy face” appearance astronauts experience when they escape Earth’s gravity. However, the more serious effects observed on orbit could include eye and vision damage.

The three Expedition 52 crew members are exploring a unique device that reverses some of these headward fluid shifts and could counter changes to vision in space. Peggy Whitson of NASA tried on the Lower Body Negative Pressure suit today with assistance from Commander Fyodor Yurchikhin of Roscosmos. NASA astronaut Jack Fischer joined the commander and conducted brain/ear fluid pressure tests and eye exams on Whitson.

Back on Earth, three new Expedition 52-53 crew members will see their Soyuz MS-05 rocket roll out to its launch pad Wednesday. The trio from the United States, Russia and Italy will blast off inside the Soyuz rocket Friday at 11:41 a.m. EDT from the Baikonur Cosmodrome in Kazakhstan. Randy Bresnik of NASA, Sergey Ryazanskiy from Roscosmos and Paolo Nespoli from the European Space Agency will live on the orbital complex until mid-December.
