Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev will venture outside the orbiting laboratory to collect two completed science experiments and install a new one. They will remove a microorganism study from the exterior of the Poisk module and retrieve a cassette from the Nauka module containing data on how semiconductor materials form in microgravity. The crew also will install a device on the Zvezda service module to measure bursts of solar radiation from solar flares.
If time allows, the duo will photograph one of the Progress 94 cargo spacecraft's Kurs rendezvous antennas, which failed to deploy in March following its launch to the space station.
This Roscosmos spacewalk will be the second for Kud-Sverchkov and the first for Mikaev. Kud-Sverchkov will wear an Orlan spacesuit with red stripes, while Mikaev will wear a suit with blue stripes. Cosmonaut Andrey Fedyaev will monitor and operate the European Robotic Arm from inside the station to maneuver the spacewalkers to their worksites.
This will be the 279th spacewalk supporting space station assembly, maintenance, and upgrades.
