With “I ask therefore I am” we research the philosophies that flow through all aspects of our reality.
An important part of this quest is to have conversations with experts who have a deep understanding of certain subjects. We talk about the insights of these specialists, and investigate possible solutions for societal dilemmas and personal life questions.
We’re making this world a little bit better, one question at a time
What does space farming mean for earth?
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.
Does MELiSSA ring a bell? It might! Because we already had a podcast-guest who was part of the MELiSSA initiative by the European Space Agency (MELiSSA = Micro-Ecological Life Support System Alternative). In 2020 we had a talk with Radu Giurgiu about high tech ecosystem farming. And it is Radu who got me into contact with Grace Crain saying:
“She does some fantastic research on growing plants with urine-derived fertiliser, moreover, she is a talented communicator”.
Remember Radu? ;-)
Radu told me I had to schedule a talk quickly because Grace was only temporarily doing research at Ghent university (Belgium), the university in our home city. I could not let this opportunity slip by to talk to this aspiring astro-biologist.
Grace immediately replied positively because she is passionate about science communication and outreach about regenerative and holistic approaches for food systems on future planetary bases.
At the moment Grace does a PhD at ETH Zurich (Switzerland). Before that she obtained a Master in Biology at El paso uni, 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!
