This is the eighth spacewalk for the Lake Orion native, who is joined by fellow Expedition 55 Flight Engineer Ricky Arnold to complete work on the outside of the ISS. The live coverage of the event started at 6:30 am EDT, and started with a stream of the astronauts getting ready for the NASA space walk and putting on their spacesuits.
The spacewalkers will remove a failed PFCS and return it to the spare parts depot. They need to rearrange the space station's external cooling system by swapping the positions of two spare ammonia pumps.
The duo then removed and replaced a camera group and a degraded Space to Ground Transmitter Receiver Controller.
This is the 210th spacewalk at the ISS since 1998.
A second spacewalk involving Arnold and Feustel is scheduled for June 14.
Meanwhile, the station's six-man crew is expecting a delivery.
As of the publishing of this article, there is plenty of time left during the mission so you'll be able to see the majority of the process if you tune in now.
