The Division of Chemical, Bioengineering and Environmental Transport (CBET) in the Engineering Directorate of the National Science Foundation (NSF) is partnering with The Center for the Advancement of Science in Space (CASIS) to solicit research projects in the general field of fluid dynamics, particulate and multiphase processes, combustion and fire systems, thermal transport processes, and nanoscale interactions that can utilize the International Space Station (ISS) National Lab to conduct research that will benefit life on Earth. 

Funding for ISS Experiments:   NSF awards under this solicitation will provide PIs with support to conduct fundamental and translational research, to prepare experiments for execution onboard the ISS, to collaborate with service providers as necessary, to provide preliminary analysis to conduct the experiment, to analyze and interpret data, and to disseminate results broadly. CASIS operations will assist grantees in translating ground-based experiments and technologies into an appropriate ISS certified hardware solution where possible. All costs associated with the translation of the proposed experiments to flight experiments onboard the ISS, including training of ISS crews, transporting the experiment payload and equipment to the ISS, and conducting experiments on the ISS, will be supported by CASIS through their cooperative agreement with the National Aeronautics and Space Administration (NASA).
