Team members aboard the International Space Station conducted scientific investigations during the week of June 13 that included autonomous monitoring of team acoustics, analyzing splash and turbulence in liquids, and testing a dosimeter of fiber optic radiation.Here are details on some of the microgravity research currently being carried out at the orbiting lab:The SoundSee mission, sponsored by the International Space Station National Laboratory, tests using an audio sensor installed on Astrobee to monitor the station's acoustic environment.The microphones collect the acoustic information, and the free-flying robot Astrobee determines the position of the sensor.Monitoring sound can provide early indications of equipment failure, improving crew health and safety by keeping life support and exercise equipment in good working order and reducing crew workload.Autonomous audio monitoring of equipment on Earth has potential uses in manufacturing, home, health care, and infrastructure development.The crew prepared the Astrobee and conducted operations for SoundSee during the week.Sensors for the SoundSee mission, which tests the use of an audio sensor attached to an Astrobee to monitor the station's acoustic environment.Monitoring sound can provide early indications of equipment failure, improving crew health and safety by keeping life support and exercise equipment in good working order and reducing crew workload.Image Credit: NASAFLUIDICS, an investigation of the European Space Agency (ESA), uses three liquid-filled spheres to observe and analyze the sloshing and turbulence of waves.A better understanding of the sloshing of liquids in a tank in microgravity could improve the orientation and accuracy of satellites and optimize the lifespan of these craft through better fuel utilization.The turbulence of waves on the surface of liquids is affected by gravity on Earth, but in microgravity, scientists can only study the surface tension of the liquid.Examining wave turbulence could provide insights into how to measure the volume of liquid in a sphere, which would help improve ways of determining how much fuel is left in a tank.On Earth, the results of this research could provide a better understanding of how Earth's oceans work, help improve climate prediction systems, and optimize the use of renewable energy from the ocean.During the week, crew members began testing the experiment.Hardware for ESA's FLUIDICS investigation, which uses liquid-filled spheres to analyze the sloshing and turbulence of waves.A better understanding of these behaviors could improve satellite guidance and accuracy, and liquid fuel measurement and management.Image Credit: NASAIlluminating radiation doseLumina, an ESA investigation, demonstrates a dosimeter that uses optical fibers to monitor the radiation dose received by crew members.The fibers darken when exposed to radiation, providing reliable measurements in complex radiation environments.Radiation monitoring is a key capability for future long-duration space exploration, and this technology could help protect crew members by allowing them to anticipate and respond to potentially dangerous radiation flares.This technology also has potential applications in Earth's medical and nuclear industries.During the week, crew members collected and transferred data from the Lumina device.NASA astronaut Robert Hines works on the Combustion Integrated Shelf, the space station platform to research, among other things, fire safety, fuel efficiency, and flame suppression.Image Credit: NASAOther investigations involving the crew:The space station is a robust microgravity laboratory with various specialized research facilities and tools.It has operated continuously for more than two decades, supporting many scientific breakthroughs from research spanning all scientific disciplines.The orbiting laboratory conveys benefits for future space exploration, advances basic and applied research on Earth, and provides a platform for a growing commercial presence in low Earth orbit.Image of Maludam National Park, in the South China Sea in eastern Malaysia, taken while the International Space Station orbits 420 kilometers above the Maludam Peninsula.Image Credit: NASAFor more news in Spanish, follow @NASA_es and sign up for the weekly newsletter here.For more news in English about research aboard the station, follow @ISS_Research and Space Station Research and Technology News.Follow ISS National Lab for information on its sponsored research.And, for a chance to see the International Space Station pass over your city, check out Spot the Station.By John Love Johnson Center, Houston, TexasTranslation into Spanish: National University of Mar del Plata Mar del Plata, ArgentinaRead this story in Spanish here.NASA OFFICER DR.MAMTA PATEL NAGARAJA
