The six-member Expedition 59 crew had a chance to sleep in the day after wrapping up a successful spacewalk on the Russian side of the International Space Station. The cosmonauts are cleaning up this afternoon from yesterday’s excursion while the rest of the orbiting crew focuses on exercise research and other light science duties.

NASA astronauts Nick Hague and Christina Koch woke up after lunch today and strapped themselves into an exercise bike inside the U.S. Destiny laboratory module. The duo took turns working out on the specialized bicycle attached to sensors for the experiment measuring oxygen uptake and aerobic capacity.

Flight Engineers Anne McClain and David Saint-Jacques checked on a couple of life science experiments during their relaxed afternoon. McClain updated software for the Photobioreactor study exploring how microalgae can create a hybrid life support system for astronauts and Earthlings. Saint-Jacques turned off and stowed the Canadian Bio-Monitor device that can quickly analyze human biological samples in space.

Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin are reconfiguring the Pirs airlock, cleaning spacesuits and stowing tools following Wednesday’s six hour and one minute spacewalk. The cosmonauts also debriefed spacewalk experts on the ground discussing their hardware removal and experiment jettisoning tasks.

    1. Oxygen is generated aboard the space station using specialized life support systems and delivered in tanks aboard resupply ships as well. Carbon dioxide is scrubbed from the station’s atmosphere with a variety of environmental control systems.
