NASA: Expedition 52 Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy, of the Russian space agency Roscosmos, will don their spacesuits and exit the station's Pirs airlock at approximately 10:45 a.m. by Kathryn Hambleton and Dan Huot
'The two Russian cosmonauts will venture outside the International Space Station
Thursday, Aug. 17, to deploy several nanosatellites, collect research
samples and perform structural maintenance. Coverage of the spacewalk
will begin at 10 a.m. EDT on NASA Television and the agency’s website.
'Ryazanskiy will begin the schedule of extravehicular activities with
the manual deployment of five nanosatellites from a ladder outside the
airlock. The satellites, each of which has a mass of about 11 pounds,
have a variety of purposes.
'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.
'The spacewalkers also will collect residue samples from various
locations outside the Russian segment of the station and install
handrails and struts to facilitate future excursions.
'Yurchikhin will be designated extravehicular crew member 1 (EV1) for
this spacewalk, the ninth of his career. Ryazanskiy, embarking on his
fourth spacewalk, will be extravehicular crew member 2 (EV2). Both will
wear Russian Orlan spacesuits bearing blue stripes.'
