Astronauts Reid Wiseman of NASA and Alexander Gerst of the European Space Agency began a 6-hour spacewalk just after 8 a.m. ET Tuesday to replace a power regulator and move a cooling pump outside the International Space Station.
Interested parties can watch the extra-vehicular activity (EVA) live via the video stream below:
Wiseman and Gerst blasted to the ISS aboard a Soyuz on May 28 as part of the Expedition 40 crew, and Tuesday’s EVA marks a first for both of them. A second 6-hour EVA to conduct further repairs is scheduled for Oct. 15, when Wiseman will be joined outside by NASA flight engineer Barry Wilmore, who launched to the ISS as part of Expedition 41 on Sept. 26.
According to the ISS’s official Twitter account, the two are wearing new NASA spacesuits recently carried to the ISS by the most recent SpaceX Dragon cargo resupply ship, which took off for the station on Sept. 20.
