It sounds counterintuitive but it is real: Space exploration teaches us a lot about life on earth! This is yet again proven during this podcast-conversation with Grace Crain, MELiSSA Doctoral Student at ETH Zurich Group of Plant Nutrition.



Before her PhD, she studied a Master in Biology in El paso, Texas (USA). She knows a lot about plant ecology, natural resource management and restoration, and desert ecology/biogeochemistry. As a US citizen she is our first podcast guest from another continent! EXCITING!

Grace’s research within the MELiSSA project focuses on determining the suitability of using human excreta for hydroponic crop production for future long-term space missions. Or in other words: Research on using pee and poo to grow plants in space.

This podcast conversation starts with Grace’s research, but of course the dialogue expands with the latest developments in space exploration, earth ecosystems, food producing ecosystems, circular economy and even space-colony politics!

Basically, this became a podcast with 2 people/nerds that are passionate about space exploration as a challenge for humanity, and as a way to better the understanding of our planetary ecosystems.

ENJOY the delightful and in depth conversation with Grace Crain!
