Watch Russian Cosmonauts Spacewalk to Find the Cause of a Mysterious ISS Leak
In late August, astronauts aboard the International Space Station awoke to a message from the ground saying that there could be a leak somewhere on board. Atmospheric pressure was slowly dropping, and the ISS crew spent the next few hours hunting down that leak. Eventually, they found it hiding in one of the Soyuz capsules used to bring supplies and people to the station. The hole was patched, but speculation about how it got there remained.
Today, two Russian cosmonauts-Oleg Kononenko and Sergei Prokopyev-are taking an unprecedented spacewalk to find some answers. During a 6-hour mission that started at 11 a.m. Eastern, the two will cut through the outer shell of that Soyuz to get a good look at the hole from the outside.
The spacewalk is being livestreamed on NASA TV, and you can watch it here:
