iss053e027113 (9/18/2017) --- NASA astronaut Joe Acaba during the Zero Boil-Off Tank Hardware Setup in the Microgravity Science Glovebox (MSG). Zero Boil-Off Tank (ZBOT) uses an experimental fluid to test active heat removal and forced jet mixing as alternative means for controlling tank pressure for volatile fluids. Results from the investigation improve models used to design tanks for long-term cryogenic liquid storage, which are essential in biotechnology, medicine, industrial, and many other applications on Earth.
