Reduced-gravity environments are unique in that they not only represent a new set of conditions for the conduct of scientific research, but also present technical challenges that must be met in order to implement both human and robotic space exploration. In particular, transport phenomena (fluid flows and heat and mass transfer) which are often key controlling mechanisms in many physical, chemical, and biological systems are significantly different under low-gravity conditions. Many mission-operating and life-support technologies also involve transport phenomena. Predictive models for low gravity performance and operation of such technologies are inadequate or non-existent. Therefore, a knowledge base is needed for the design and development of reliable, efficient, and cost-effective space equipment and systems. Discussion will be presented in this paper on how low-gravity transport phenomena impact the operation of space systems and what gaps in knowledge need to be filled in order to develop future system designs. Some of what has been learned about low-gravity transport will also be reviewed.
