NASA astronauts Ricky Arnold and Drew Feustel will head out on their third space walk together this year later today, Thursday, June 13.
The two veteran astronauts are expected to begin the spacewalk at 1.10pm UK time (8.10am EDT) which you can watch live right here.
The NASA live stream embedded below will broadcast the ISS Expedition 56 astronauts on their daring mission.
NASA’s cameras onboard the ISS will begin live coverage on NASA TV at 11.30am UK time (6.30am EDT).
Today’s space walk marks the 211th time astronauts onboard the international space laboratory are leaving its safe walls.
The NASA astronauts are tasked with installing a series of brand new HD cameras to support future commercial missions from private rocket company SpaceX and Boeing.
The rocket companies’ first unmanned test missions are scheduled to begin by the end of the year.
In a statement, NASA said: “The two spacewalkers will install brackets and high-definition cameras near an international docking adapter mated to the front end of the station’s Harmony module.
“The additions will provide enhanced views during the final phase of approach and docking of the SpaceX Crew Dragon and Boeing Starliner commercial crew spacecraft that will soon begin launching from American soil.
“During their spacewalk, the astronauts also will swap out a camera assembly on the starboard truss of the station and close an aperture door on an external environmental imaging experiment outside the Japanese Kibo module.”
The two NASA astronauts will be cheered on and supported by fellow scientists and crew mates Serena Auñón-Chancellor and Alexander Gerst.
Both astronauts only arrived at the ISS last Friday onboard a Russian a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
Dr Gerst will directly proved support during the mission by helping the spacewalker in and out of their cumbersome spacesuits.
Dr Auñón-Chancellor will meanwhile operate the robotic Canadarm2 robo-arm to assist the astronauts.
Ahead of the critical mission, the duo had some time to practice procedures of manoeuvring the spacewalker to and from the worksite on the ISS’ exterior.
About five hours and 23 minutes into the broadcasted space walk, Dr Feustel will beat NASA astronaut Peggy Whitson’s cumulative 60 hours and 21 minutes in space, to move in to third place behind Michael Lopez-Alegria and Anatoly Solovyev.
Dr Feustel has so far only spent out over 42 minutes in outer space.
