Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub began a spacewalk at 1:49 p.m. EDT to install a synthetic radar communications system, release a nanosatellite to test solar sail technology, and inspect and photograph an external backup radiator on the Nauka multipurpose laboratory module. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.

Kononenko is wearing an Orlan spacesuit with red stripes, while Chub is wearing the suit with blue stripes. This is the sixth spacewalk in Kononenko’s career, and the first for Chub. It is the 268th spacewalk for space station assembly, maintenance, and upgrades.
