Two Russian cosmonauts worked to install and retrieve science experiments while on a spacewalk outside the International Space Station on Wednesday (May 27).
Expedition 74 commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev spent 6 hours and 5 minutes outside the space station, conducting an extravehicular activity (EVA) that ran from 10:18 a.m. to 4:23 p.m. EDT (1418 to 2023 GMT). The two spacewalkers installed a solar radiation experiment on the exterior of the Zvezda service module and removed science hardware from the Poisk and Nauka modules on the station's Russian segment.
