Abstract

The future of humanity is often rendered in spectacular visions of a multiplanetary civilization with a booming space economy. Reaching this reality requires addressing one of the core needs of survival: food. Porous ceramics used for Passive Porous Tube Nutrient Delivery Systems (PPTNDS) offer a promising solution. In microgravity environments such as the International Space Station (ISS), fluid dynamics and liquid coagulation do not support conventional agricultural practices. Porous ceramic materials present a solution that enables nutrient solution diffusion via capillary action.

In this research, it was determined that extruding a wadding ceramic tube and sintering it at 1900 °F for 6 hours matches the porosity, water uptake, and pore size requirements prescribed by NASA. This material not only outperformed NASA’s current alumina-based device but also offered higher flexibility for recipe optimization. Additionally, it is substantially cheaper than their current supplier.
