A pair of German experiments took place aboard the International Space Station today including a space exercise study and the installation of an Earth spectral sensor. The Expedition 56 crew members are also looking ahead to Wednesday’s Russian cargo ship departure and a pair of U.S. spacewalks in September.

Astronaut Alexander Gerst of ESA (European Space Agency) exercised today in a t-shirt designed with a specialized fabric for the SpaceTex-2 study. The research, sponsored by the German Aerospace Centre (DLR), is evaluating whether the custom t-shirt provides comfort, efficient thermal control and sweat evaporation during a workout in microgravity.

Commander Drew Feustel worked on another DLR experiment that will provide hyperspectral imagery of the Earth. Feustel is readying the German-built Earth spectrometer for its installation outside of the Japanese Kibo laboratory module. It will monitor urban and agricultural development, the health of vegetation and water areas as well as the environmental effects of natural and manmade disasters.

Russia’s Progress 69 (69P) cargo craft loaded with trash is poised for its undocking Wednesday at 10:16 p.m. EDT from the aft port of the Zvezda service module. The 69P will orbit the Earth for seven more days of engineering tests before it deorbits over the Pacific Ocean for a fiery but safe disposal.

Two U.S. spacewalks are planned for Sept. 20 and 26 to replace batteries on the space station’s Port 4 truss structure power channels. Gerst will join Feustel on the first spacewalk then go out again on the second spacewalk with NASA astronaut Ricky Arnold. The batteries are targeted for delivery on Sept. 14 aboard Japan’s “Kounotori” HTV resupply ship.

The Expedition 56 crew members explored using algorithms to remotely control a robot on the ground and satellites from the International Space Station today. The orbital residents are also cleaning up after a Russian spacewalk while preparing for a pair of upcoming U.S. spacewalks and a Japanese cargo mission.

Astronaut Alexander Gerst of the European Space Agency is testing the ability to control a robot on a planetary surface from an orbiting spacecraft. The study seeks to bolster the success and safety of future space missions with astronauts and robots sharing decision-making responsibilities.

Commander Drew Feustel joined Flight Engineer Ricky Arnold in the Japanese Kibo lab module monitoring a pair of tiny internal satellites, also known as SPHERES. They are evaluating an algorithm that controls the operation of the SPHERES in formation using six degrees of freedom.

Cosmonauts Oleg Artemyev and Sergey Prokopyev are cleaning up after Wednesday’s spacewalk enabling new science outside of the space station. The two dried out their Russian Orlan spacesuits and water feed lines then began stowing spacewalk tools and gear.

At the end of the day, Gerst started charging U.S. spacesuit batteries ahead of two maintenance spacewalks planned for Sept. 20 and 26. Gerst and fellow spacewalkers Feustel and Arnold will replace batteries on the Port 4 truss structure’s power channels. The Japanese “Kounotori” HTV-7 cargo ship is targeted to deliver the new batteries ahead of the two spacewalks on Sept. 14.

Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos have completed a spacewalk lasting 7 hours and 46 minutes.

The two cosmonauts opened the hatch to the Pirs docking compartment to begin the spacewalk at 12:17 p.m. EDT. They re-entered the airlock and closed the hatch at 8:03 p.m. EDT.

During the spacewalk, the duo manually launched four small technology satellites and installed an experiment called Icarus onto the Russian segment of the space station.

It was the 212th spacewalk in support of International Space Station assembly, maintenance and upgrades, the third in Artemyev’s career and the first for Prokopyev.

Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos began a spacewalk when they opened the hatch of the Pirs docking compartment of the International Space Station at 12:17 p.m. EDT.

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.

Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos are preparing for their exit from the station’s Pirs docking compartment airlock at approximately 11:58 a.m. EDT. The spacewalk is planned to last about six hours outside of the International Space Station‘s Russian segment.

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.
