Ongoing exercise research and gym maintenance took place aboard the International Space Station to ensure astronaut health and mission success. The Expedition 56 crew members also worked on autonomous satellite operations and botany and astronomy gear.

European Space Agency astronaut Alexander Gerst has been participating in an exercise study all week developed by the German Aerospace Centre (DLR). He has been working out in a custom t-shirt with a specialized fabric for the SpaceTex-2 experiment that may improve an astronaut’s comfort and thermal relief while working out in space.

A treadmill is getting its twice-yearly checkup today in the Tranquility module. Flight Engineer Serena Auñón-Chancellor of NASA spent Friday morning checking the treadmill’s belt tension, greasing axles and replacing parts. Engineers on the ground will review its condition before the crew gets back on the treadmill for daily runs.

Commander Drew Feustel set up a pair of tiny internal satellites today, known as SPHERES, and tested the autonomous operation of the free-floating devices.  The SmoothNav experiment is researching using algorithms that spacecraft may use to operate and communicate with each other when conducting space-based tasks.

NASA astronaut Ricky Arnold worked on botany and astronomy gear inside the orbital lab. The former teacher reinstalled the Plant Habitat during the morning after some maintenance work on the Japan Kibo lab module’s EXPRESS rack.

In the afternoon, Arnold switched to the METEOR experiment installing new computer software and positioning a camera in the U.S. Destiny lab module’s Window Observational Research Facility. METEOR observes and takes spectral measurements of the chemical composition of meteors entering Earth’s atmosphere.

A Russian cargo ship departed the International Space Station Wednesday night as another resupply mission from Japan is planned in September. The Expedition 56 crew members also observed protein crystals, studied an ancient navigation technique and researched time perception in space.

Two Soyuz crew ships and a Progress resupply ship remain docked at the orbital lab after the Progress 69 (69P) cargo craft undocked from the Zvezda service module Wednesday at 10:16 p.m. EDT. It will orbit Earth until Aug. 29 for engineering tests monitored by Roscosmos mission controllers before deorbiting over the Pacific Ocean.

The next resupply mission is coming from the Japan Aerospace Exploration Agency’s “Kounotori” H-II Transfer Vehicle. It is targeted for launch Sept. 10 to deliver science, supplies and batteries for installation during a pair of spacewalks next month. Russia’s next resupply mission, the Progress 71, is targeted for a two-day trip to the station at the end of October.

Commander Drew Feustel continued working on a pair of similar protein crystal experiments today. The BioServe Protein Crystalography-1 and Protein Crystal Growth-13 studies allow astronauts to observe crystal growth in space and analyze the results. This saves researchers time without having to wait for samples to be returned to Earth for analysis.

Alexander Gerst of ESA assisted Serena Auñón-Chancellor from NASA and tested using a sextant in space for celestial navigation during an emergency. The duo worked inside the Cupola today and tested stability, positioning and sighting with the device using a star map.

Gerst then switched his attention to a European Space Agency study exploring how astronauts perceive time in space. Researchers seek to quantify subjective changes in time perception to understand how astronauts navigate, move and hear in space.
