NASA astronaut Nichole Ayers processes bacteria samples for viewing inside a 3D imaging microscope

iss073e0025978 (May 9, 2025) --- NASA astronaut and Expedition 73 Flight Engineer Nichole Ayers works in the Kibo laboratory module's Life Sciences Glovebox processing bacteria samples before viewing them inside a 3D imaging microscope called Extant Life Volumetric Imaging System, or ELVIS. The technology demonstration may enable applications for monitoring water quality, detecting infectious organisms on spacecraft, and researching colloids (suspensions of particles in a liquid) and microorganisms in microgravity.
