Amateur astronomers can tune in live Monday morning at 9:30 a.m. EDT, when two Russian cosmonauts leave the International Space Station for a six-and-a-half-hour spacewalk to conduct maintenance repairs on the nearly 20-year-old machine.

Alexander Skvortsov and Oleg Artemyev of the Russian Federal Space Agency are scheduled to step out of the ISS around 10 a.m. EDT in order to release small Peruvian science satellites that will conduct experiments on the outer exterior of Russian nanosatellites, according to



The space walk will be the second mission for both cosmonauts, who live and work aboard the International Space Station. While a video of the undertaking has been embedded below, NASA also provided a live stream of the events.

Skvortsov and Artemyev began preparing for their spacewalk weeks ago, preparing cooling loops and installing necessary elements into their space suits.

“Once all that was completed, Skvortsov and Artemyev looked through the station’s windows to study the paths they will take to the various worksites on the exterior of the station for the spacewalk,” the space Fellowship reported earlier this month. “During the excursion, the two cosmonauts will deploy a nano satellite, install two experiment packages on the station’s hull and bring three other packages back inside.”
