jsc2021e019403 (1/29/2021) --- A Techshot Fluid Processing Cassette that is part of Techshot’s ADSEP fleet of spaceflight hardware facilities. The flight hardware cassette is loaded with small aquarium bags containing the juvenile bobtail squid. Once launched into space, the aquarium bags will inoculated with luminescent bacterium to start the normal symbiosis with the squid. Understanding of Microgravity on Animal-Microbe Interactions (UMAMI) examines the effects of spaceflight on the molecular and chemical interactions between beneficial microbes and their animal hosts.
