Expedition 52 Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy, of the Russian space agency Roscosmos began a planned six-hour spacewalk from the Pirs Docking Compartment of the International Space Station at 10:36 a.m. EDT.

Space Station Cosmonauts take a Walk in Space

Both spacewalkers are wearing Russian Orlan spacesuits with blue stripes. Yurchikhin is designated extravehicular crew member 1 (EV1) for this spacewalk, the ninth of his career. Ryazanskiy, embarking on his fourth spacewalk, is extravehicular crew member 2 (EV2).

Spacewalk Comes to a Close

The two spacewalkers exited the Pirs Docking Compartment Station at 10:36 a.m. EDT. Among their accomplishments was manual deployment of five nanosatellites from a ladder outside the airlock.

One of the satellites, with casings made using 3-D printing technology, will test the effect of the low-Earth-orbit environment on the composition of 3-D printed materials. Another satellite contains recorded greetings to the people of Earth in 11 languages. A third satellite commemorates the 60th anniversary of the Sputnik 1 launch and the 160th anniversary of the birth of Russian scientist Konstantin Tsiolkovsky.

They also collected residue samples from various locations outside the Russian segment of the station.

During their work, the cosmonauts mounted scientific equipment on the external surface of the station for the experiments "Restoration" and "Impact", took samples for microbial contamination in four working areas, installed new samples of materials for long exposure in open space, was launched with a hand and using a trigger Five nano-satellites, photographed the outer surface of Russian modules and their individual structural elements. To ensure movement along the surface of the station, astronauts installed soft handrails and struts. The handrail is not installed - the transition from the module "Search" (MIM-2) to the module "Dawn" (FGB).

Roscosmos cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy completed the first in 2017, the way out of the International Space Station (ISS) for the Russian program. The astronauts fulfilled their assigned tasks.
