Two Russian cosmonauts will take a spacewalk today, Aug. 15, at 11:58 a.m. EDT (1558 GMT) and you can watch the action at the International Space Station live here, courtesy of NASA TV. NASA's webcast of the spacewalk will begin at 11:15 a.m. EDT (1515 GMT). You can also watch the event directly via NASA TV.
Cosmonauts Oleg Artemyev and Sergey Prokopyev are expected to spend over 6 hours working outside the space station to perform maintenance, install new experiments and toss a few tiny satellites into space.
The engine is an RS-25, which is provided by Aerojet Rocketdyne.
"Russian cosmonauts living and working on the International Space Station will venture outside Wednesday, Aug. 15, for a spacewalk expected to last about six hours. Live coverage of the excursion will air on NASA Television and the agency’s website.
"Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos are scheduled to exit the Pirs airlock at 11:58 a.m. EDT. Live coverage of the spacewalk will begin at 11:15 a.m.
"Artemyev and Prokopyev will manually launch four small technology satellites, retrieve material science samples from the hull of the Zvezda service module, and install an experiment called Icarus onto the Russian segment of the space station.
"Icarus is a collaborative environmental experiment between the German Aerospace Center (DLR) and Roscosmos to study the migratory patterns of small animals on Earth. It consists of an antenna and GPS hardware to track the movements of animals that have been tagged with small GPS receivers. The experiment may provide data about how animals move from one location to another, how animal population density shifts over time, and how diseases spread.
"The spacewalk will be the 212th in support of station assembly, maintenance and upgrades, the third in Artemyev’s career and the first for Prokopyev. Artemyev will be designated extravehicular crew member 1 (EV1) for the spacewalk, while Prokopyev will be extravehicular crew member 2 (EV2)."
