Experiments are being conducted every day on the ISS, and many technologies developed there are already in use today. One of the main aspects of the space environment that’s different from a lab on Earth is the increased amount of radiation. This has posed an issue for electronics in space that are susceptible to damage from radiation, but experiments done on the ISS have resulted in new hardened electronics with increased efficiency.
Microgravity on the ISS has also helped with medical advances. Microfluidics is the study of how fluids behave in small capillaries. Understanding microfluidics is super important in targeted drug delivery, and the ISS environment takes gravity out of the equation which makes the math of microfluidics easier to calculate. Companies developing medical devices dependent on microfluidics test them in the national lab on the ISS for this reason, and have seen great results.
