Two Russian astronauts will embark on a spacewalk outside the International Space Station on Wednesday afternoon.
Oleg Artemyev and Sergey Prokopyev, of the Russian space agency Roscosmos, are expected to spend more than six hours outside the station.
They are scheduled to exit the Pirs airlock at 11.58am EDT (4.58pm BST).
During the spacewalk they will perform maintenance and launch a few small satellites.
The spacewalk will be the 212th in the International Space Station's history.
