Can you actually grow potatoes on Mars? On this episode, Neil deGrasse Tyson and comic co-host Paul Mecurio explore how to grow plants in space and whether we can farm on the Moon and Mars with University of Florida Space Plants Lab biologists Anna-Lisa Paul and Robert Ferl.

Do we have experience trying to grow things on moon soil? Learn about regolith and the moon dirt brought back by the Apollo missions. What is the difference between dirt and soil? What are the challenges of growing plants in non-living soil? Discover orbital plant research, microgravity, and what happens to biology when not protected by Earth’s magnetic field. How do plants respond to space at a molecular level?

What types of plants are used for space plant research? Learn about Arabidopsis thaliana and its role in space plant research. What does it taste like? Discover the many ways to stress a plant out. Are different areas of the moon better for farming? We explore what makes good soil and what regolith might need to make growing plants more viable.

How does zero gravity affect how plants grow? How do plants know which direction to grow? Do plants grow toward light or against gravity? Is it a bit of both? Will future astronauts have to be vegetarians? Would food taste better or worse grown on the moon? What about moon wine? You will learn about other possible space-grown food. Could human feces be used as fertilizer like on The Martian? All that, plus, in the space-horticulturalist sequel who would play Anna-Lisa and Robert?
