During their time on the International Space Station many astronauts have the opportunity to participate in spacewalks, also known as Extravehicular Activities (EVA). These spacewalks play a critical role in keeping the station functional as it travels approximately 17,500 miles per hour 250 miles above the Earth’s surface. In this episode, Expedition 55/56 Flight Engineer Ricky Arnold talks about the extensive training needed for spacewalks on the ground prior to a mission on the space station, and how it helps prepare astronauts for spacewalks outside of the station in low-Earth orbit.
