Aug. 9 (UPI) -- Two Russian Cosmonauts conducted a spacewalk Wednesday to upgrade systems on the International Space Station.
Before they set out on the spacewalk, NASA officials said cosmonauts Sergey Prokopyev and Dmitri Petelin "will venture outside the station's Poisk airlock to attach three debris shields to the Rassvet module."
NASA said the pair "will test the sturdiness of a work platform that will be affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module."
The spacewalk is Petelin's sixth and Prokopyev's eighth, according to NASA.
NASA livestreamed the spacewalk on YouTube, its website and on the NASA app.
The spacewalk was expected to last about seven hours.
