Roscosmos cosmonauts Sergey Ryazansky and Fyodor Yurchikhin working onboard the International space station embarked on a planned spacewalk. As reported last time, work on the outer surface of the Russians spent more than six months ago, February 3, 2016.
Among the challenges facing the astronauts, mentioned the launch of five nano-satellites, three of which were created by students in honor of the 60th anniversary of the launch of the first artificial Earth satellite. Also among the satellites — “Tomsk-TPU-120”, created in Tomsk Polytechnic University jointly with the Corporation “Energy” and is the first Russian nanosatellite class CubеSat, the body of which is printed on a 3D printer. It will be about a year and a half to transfer to the Ground voice messages and telemetry. “Catch” this signal can, in particular, Amateurs who set up the receivers to the frequency 437.025 MHz.
Another objective of the spacewalk is to test in space new space suit “Orlan-MKS”, created at the NPP “Star”. As reported, according to its technical solutions, it is better than the previous generation of Russian spacesuits “Orlan-MK”, but the American EMU. This suit works Fyodor Yurchikhin. Previously, experts had said that by replacing the rubber shell on a polyurethane, the engineers managed to extend the use of spacesuits from four to five years, and the number of spacewalks from 15 to 20.
In addition, the astronauts have repaired a highly directional antenna on the service module “Zvezda”, to clear one of the portholes of the ISS Russian segment and to perform several other tasks.
