The Expedition 38 crew members worked throughout Friday on long term experiments to benefit life on Earth and in space. The six space station residents also exercised to stay fit and checked station systems to ensure the orbital laboratory is in excellent condition.
Japanese astronaut Koichi Wakata along with NASA astronaut Rick Mastracchio participated in more eye exams Friday for the Ocular Health study. They scanned their eyes with an ultrasound device, checked their blood pressure and took electrocardiograms of their cardiac activity. Wakata later attached sensors to his arm that measure how a crew member’s biological clock, or circadian rhythm, adapts to a long term space mission.
Flight Engineer Mike Hopkins continued his work with the long-running Capillary Flow Experiment. He downlinked live video of the test runs showing how liquids behave in containers of various geometries in the microgravity environment. Results could benefit future spacecraft with advanced fuel and water delivery systems.
Wakata and Hopkins also joined each other to record a video message for the Japan Aerospace Exploration Agency. Mastracchio later stowed the Ocular Health medical gear and jotted down his thoughts for the Journals study which gives doctors an insight to a crew members thoughts while living in space.
Commander Oleg Kotov transferred more gear from the ISS Progress 53 resupply ship that docked to the Zvezda service module last Friday. He also inventoried the new gear and updated the station’s inventory management system. Kotov also collected imagery for the Albedo experiment which seeks to develop methods to harness Earth’s reflected radiation to supplement the station’s power supply.
Kotov and Flight Engineer Sergey Ryazanskiy started their morning setting up and photographing the NAPOR-mini experiment gear for inspection. The experiment is testing new technology that downlinks Earth observation video from Zvezda to Russian ground stations. The videos could help scientists monitor ecological and environmental conditions from the space station.
Veteran cosmonaut and Flight Engineer Mikhail Tyurin worked throughout his day upgrading Russian laptop computers. He also pressurized the Elektron oxygen generator before activating it in the station’s Russian segment.
