ISS Science for Everyone

Science Objectives for Everyone
Monitoring microbes that can cause illness is crucial for maintaining crewmember health. Microbiological monitoring in the International Space Station-KIBO (Microbe-IV) uses several passive devices to capture and sample microbes, such as bacteria and fungus, on the International Space Station (ISS). The sampling devices will be frozen and returned to Earth, where researchers and students will count and classify the microbes. Sampling the microbial environment on the ISS will help scientists monitor the station’s air purity.

    Experiment Description

    Research Overview

    • In the JAXA KIBO Utilization scenario, studies on the relationship between human and microbes in space habitation environments are critical for success in long-duration missions. In respect to human health, the importance of microbiological monitoring is extremely important for long-duration missions. In this investigation, the major focus is on indoor environmental quality control, specifically studies on environmental microbiology in space (astromicrobiological studies), in order to reduce potential hazards for the crew and the spacecraft infrastructure. Progress is made in these astrobiological studies based on past, and current, collaborative studies with JAXA. The continuing expansion of the on-going microbiological monitoring in the KIBO module, the project named “Microbe-I/II/III”, data is being collected on microbial dynamics in the habitable spacecraft environment. Collected data on these microbial communities aboard the ISS is shared with NASA, ESA, and JAXA.
    • To monitor microbial populations aboard  ISS, it is necessary to maintain the health of the crewmwmbers. Passive sampling and analysis on the ground clarifies the type, and number, of microbes in the KIBO module. Particle count data gives the real time status of air purity in the KIBO module.
    • Continuous monitoring from the Microbe-I experiments provides microbial information about the KIBO module, and enables the prediction pf future microbial populations in the KIBO module.
    • Results from this experiment provide further insight into the risk of microbial populations to crewmembers  aboard  ISS.

    Applications

    Space Applications

    Results from the Microbe-IV investigation will provide insight into the microbial environment on the space station. Microbes that can cause illness could present problems for current and future long-duration space missions. Understanding which microbe communities thrive in space habitats, known as astromicrobiology, could help researchers design antimicrobial techology.
     

    Earth Applications

    The sampling devices used for Microbe-IV could also be used on Earth. Procedures for monitoring and counting microbe populations could enable new microbe control standards for the pharmaceutical and food processing industries.

    Operations

    Operational Requirements

    Recover passive sampling items, "White Tube", "Microbial Detection Sheet" "Air Filter" and "Sampling Sheet" at frozen temperature.
    Data of particles by "Particle Counter" should be downlinked through ELT-2.

    Operational Protocols

    Sampling #1: Sampling with Sampling Sheet and store at -95 oC in MELFI. Sampling with Microbial Detection Sheet, then 7 days incubation in cabin and store at -95°C in MELFI. Photograph before and after incubation.
    Sampling #2: Sampling with Wet Wipe and kept in white tube and Sampling Sheet, store at -95°C. Air sampling with NASA, ASD, and JAXA Particle counter for 2 times, then store air filter at -95°C in MELFI.
