Artemyev will be designated extravehicular crew member 1 (EV1) for the spacewalk wearing the Russian Orlan spacesuit with red stripes. Prokopyev will be extravehicular crew member 2 (EV2) wearing the Russian Orlan spacesuit with blue stripes.
Coverage of the spacewalk continues on NASA Television and the agency’s website. Views from a camera on Artemyev’s helmet are designated with the number 20, and Prokopyev’s is labeled with the number 18.
The primary objectives during the spacewalk will be to 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.
Coverage of the spacewalk is now underway on NASA Television and the agency’s website.
The Expedition 56 crew is getting ready for a spacewalk Wednesday outside the International Space Station’s Russian segment. Meanwhile, the orbital residents continued apace with space science and preparation for a pair of September spacewalks.
Two cosmonauts will suit up inside their Orlan spacesuits and exit the Pirs airlock Wednesday at 11:58 a.m. EDT for about six hours of science and maintenance work. Oleg Artemyev and Sergey Prokopyev will toss four tiny satellites into space, install antennas and cables for the Icarus animal-tracking experiment and collect exposed science experiments.

The duo will hand-deploy four tiny satellites, install antennas and cables and collect exposed science experiments.
Commander Drew Feustel and Flight Engineer Ricky Arnold set up a pair of tiny satellites, known as SPHERES, for operation during the SPHERES Zero Robotics student competition. Middle school students in the United States are competing to write the best algorithms to operate the SPHERES simulating a mission on Saturn’s moon Enceladus.
Alexander Gerst of ESA joined Arnold before lunchtime making space for cargo due to be delivered in Sept. 14 aboard Japan’s H-II Transfer Vehicle. Gerst then opened up the Combustion Integrated Rack in the afternoon and took pictures of ACME (Advanced Combustion via Microgravity Experiments) gear that supports five independent gaseous flame studies.
The Expedition 56 crew members explored how human health and physical processes are affected off the Earth today. The orbital residents are also configuring the International Space Station for a Russian spacewalk next week and a Japanese cargo craft mission in September.
A long-running human research study is helping doctors understand the impacts of microgravity shifting fluids upward in an astronaut’s body. Two astronauts, Serena Auñón-Chancellor of NASA and Alexander Gerst of ESA, joined forces today for that study using an ultrasound device for eye scans with assistance from specialists on Earth. The experiment aims to help researchers prevent the upward fluid shifts that put pressure on an astronaut’s eyes potentially affecting vision in space and back on Earth after a mission.
The orbital complex enables research into a variety of space physics including the observation of atoms nearly frozen still when exposed to the coldest temperatures in the universe. The Cold Atom Lab (CAL), which chills atoms to about one ten billionth of a degree above absolute zero, had its fiber cables inspected by NASA astronaut Ricky Arnold today during troubleshooting operations. CAL was delivered to the station in May aboard the Cygnus space freighter then installed in the Columbus laboratory module shortly after.
A spacewalk is scheduled for Aug. 15 when cosmonauts Oleg Artemyev and Sergey Prokopyev will work outside the station’s Russian segment for about 6 hours of science and maintenance tasks. The duo spent Wednesday afternoon checking their Orlan spacesuits in a pressurized configuration. They also installed U.S. lights and video cameras on the suits ahead of next week’s excursion.
The Japan Aerospace Exploration Agency (JAXA) is planning a Sept. 10 launch of its H-II Transfer Vehicle (HTV) for capture and installation to the space station. HTV will be carrying cargo and new lithium ion batteries for installation on the station’s Port-4 truss power system. Commander Drew Feustel partnered with Gerst and Arnold throughout the day readying JAXA’s Kibo laboratory module for the upcoming delivery mission.

Finally, they reviewed the procedures they will use next week when they exit and enter the airlock inside the Pirs docking compartment.
The rest of the crew is relaxing today after an intense week of completing crucial space science and loading the time-sensitive research samples inside the Dragon cargo craft for its return to Earth. Dragon splashed down in the Pacific Ocean Friday and was quickly retrieved so scientists and engineers could begin analyzing the science and refurbishing the station hardware.
The next spacecraft due to leave the station is Russia’s Progress 69 (69P) resupply ship on Aug. 22 packed with trash and discarded gear. It launched Feb. 13 and arrived two days later loaded with over three tons of food, fuel and supplies. The 69P will deorbit on Aug. 29 after a week of engineering tests for a fiery but safe disposal over the Pacific Ocean.
Dragon’s thrusters will be fired to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn about 5:23 p.m. The capsule will splashdown about 6:17 p.m. in the Pacific Ocean, where the SpaceX recovery team will retrieve the capsule and its more than 3,800 pounds of cargo, including a variety of technological and biological studies.
NASA and the Center for the Advancement of Science in Space (CASIS), the non-profit organization that manages research aboard the U.S. National Laboratory portion of the space station, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours of splashdown.
Dragon is the only space station resupply spacecraft currently capable of returning cargo to Earth, and this was the second trip to the orbiting laboratory for this spacecraft. SpaceX launched its 15th NASA-contracted commercial resupply mission to the station June 29 from Space Launch Complex 40 from Cape Canaveral Air Force Station in Florida on a Falcon 9 rocket that also previously launched NASA’s TESS mission to study exoplanets.
