Luke Fountain, Ph.D., who is in the third year of his NASA Postdoctoral Fellowship, makes a return to Further Together because of a recently published paper he co-authored on plant biology and space exploration. His research focus is figuring out how to grow plants in space to help enable future deep exploration. In this conversation, Fountain shares the challenges of plant biology in space, including the need to make growing systems self-sustaining. The paper he co-authored, published in the New Phytologist in November 2025, lays out a 12-point framework called the Bioregenerative Life Support System readiness level to assist in overcoming challenges to establish resilient, sustainable crop production.

Fountain's paper, "Expanding frontiers: harnessing plant biology for space exploration and planetary sustainability," can be found here. https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.70662.
