The three Expedition 49 crew members measured noise levels on the International Space Station today and continued exploring how physical and organic phenomena are affected by weightlessness.
NASA astronaut Kate Rubins surveyed the acoustic environment inside the station today. She analyzed the sound levels of various life support gear and took standard measurements in the Destiny lab module and the Zvezda service module. Rubins also partnered up with Japanese astronaut Takuya Onishi to remix, photograph and stow samples for the Hard to Wet Surfaces pharmaceutical study.
Onishi began his day testing his performance on a mobile tablet device. The study, known as Fine Motor Skills, observes how an astronaut adapts to new technology and could help engineers design next generation spacecraft, spacesuits and tools. He then moved onto setting up equipment for the upcoming Group Combustion experiment to research how fuel burns in space. Results could influence the future production of rocket engines and industrial furnaces.
On the Russian side of the station, Commander Anatoly Ivanishin sampled different areas searching for mold fungus and bacteria contamination. The commander then repressurized the station’s environment with air from a docked cargo ship and worked on life support system maintenance.
