... In this context, the ISS is unique in providing sufficient time in a microgravity environment to achieve definitive evaluation of spacecraft fire phenomena -- unachievable by short-duration microgravity facilities such as drop towers and unrealizable by computation that lacks sufficient spatial resolution. Thus, should fire safety gaps be identified that must be filled in order to reduce the fire risks on exploration missions to acceptable levels, the ISS is the only facility that could be used to conduct the studies.

... If an examination of technology needs for long-term exploration missions such as a mission to Mars were to identify MFH processes as strong candidates for meeting those needs, studies aboard the ISS of the flow and stability of drops and thin films on variable wetting surfaces in the presence of phase changes might be the only way to develop design parameters for a reliable optimized (in terms of mass and energy consumption) system.

... Successful cryo management under such circumstances will require an understanding of multiphase flow and heat transfer issues, and the ISS could serve as a unique testbed if appropriate engineering studies are planned and carried out. Finding: Multiphase flow and heat transfer systems operating in microgravity environments are profoundly influenced by thermocapillarity effects and may be significant components of exploration missions.
