The International Space Station has been flying over Hurricane Matthew all week as the storm hit the Caribbean Sea and makes its way towards Florida. While the citizens of Florida braced for the hurricane’s impact, the crew researched how living in space impacts the human body.
Astronauts Kate Rubins and Takuya Onishi collected their blood samples, spun them in a centrifuge and stored the samples in a science freezer. The samples will be examined on Earth to understand the detrimental effects of living in space on bone marrow and blood cells.
Rubins also joined Commander Anatoly Ivanishin for eye checks today to explore the headward fluid shifts astronauts experience during long-term space missions. These fluid shifts increase pressure on the brain and eyes, potentially causing vision problems. The duo used a series of tools including an ultrasound to examine their eyes.
BEAM, the new expandable module attached to the International Space Station, was opened up today for tests and equipment checks. The Expedition 49 crew also explored eating right in space, adapting to new technology and studied a variety of other life science and physics research.
Japanese astronaut Takuya Onishi started an 11-day run today to document his meals while wearing a monitor that will take water samples and measure his breathing. The ENERGY experiment will help doctor’s understand metabolism in space and ensure astronauts are properly nourished to maintain the energy required for a long-term mission. Onishi is also continuing to set up the Group Combustion fuel burning study and checked for pressure leaks in the experiment gear.
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.
Two different studies are under way on the International Space Station – one will observe how fuel burns in space while another is researching how medicine dissolves in water. Results from both experiments could benefit humans on Earth and in space.
Astronaut Takuya Onishi is setting up the Group Combustion experiment that will explore how flames spread across a cloud of fuel droplets. Observations may help engineers design advanced rocket engines, as well as gas turbines and industrial furnaces.
