Like many Americans, astronauts Randy Bresnik and Mark Vande Hei got up and went to work this morning. But instead of an office, their jobs took them on a walk outside the International Space Station. If that sounds more exciting than what you’re doing at the moment, you can watch their progress live on NASA’s website.

The spacewalk, which commenced the morning of October 5 at 8 a.m. EDT and is expected to last over six hours, is the first of three NASA plans to livestream during the month of October. On this mission, Bresnik, Expedition 53's commander, and Vande Hei, a flight engineer, are replacing one of the motorized lathes on the station’s robotic arm. The Latching End Effectors as they’re called are used to grab cargo vehicles and payloads that arrive at the station.

Bresnik has worked aboard the ISS since July and Vande Hei since September. The pair will don their spacesuits again for NASA’s second livestreamed spacewalk of the month on October 10. On October 18, Bresnik will be leading the third spacewalk and he’ll be assisted by flight engineer Joe Acaba. If you missed this event, you can follow NASA Live for more streams of spacewalks, cargo craft launches, and the occasional orbiter disintegrating in Saturn's atmosphere.
