Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of Roscosmos egressed the Pirs airlock at around 12:17 p.m. EDT on the latest International Space Station spacewalk, which was supposed to last just six hours, but lasted nearly eight hours in duration. Designated VKD-45 (or RS-45), Artemyev and Prokopyev manually launched four small technology satellites, retrieved material science samples from the hull of the Zvezda service module, and installed an experiment called Icarus onto the Russian segment of the space station.
