NASA astronaut Nichole "Vapor" Ayers, currently serving as a flight engineer on Expedition 73 aboard the International Space Station (ISS), is one of a handful of astronauts testing various experiments at the station.
As the ISS sits in low Earth orbit, its microgravity setting allows researchers like Ayers to try a variety of studies, from growing plants to creating miso paste to monitoring bone density changes to watching weird weather from space.
