Russian cosmonauts and Expedition 56 flight engineers Oleg Artemyev and Sergey Prokopyev are scheduled to venture outside the International Space Station via the Pirs airlock on the Russian Orbital Segment.
The spacewalk is currently expected to start at about 11:58 a.m. EDT (16:05 UTC) Aug. 15, 2018 when the hatch to the Pirs module is opened. During the outing, the pair will release a number of small satellites, retrieve materials science samples from the Zvezda service module and install the Icarus experiment, according to NASA.
Icarus is a joint study between the German Aerospace Center and Roscosmos to study migratory patterns of small animals on Earth using antennas and GPS hardware, NASA said.
The six-hour EVA is expected to be the 212th spacewalk in support of ISS assembly, maintenance and upgrades. It will also be the third for Artemyev and first for Prokopyev.
NASA TV coverage of the spacewalk is expected to start at 11:15 a.m. EDT (15:15 UTC) Aug. 15, 2018.
