Luke Fountain, Ph.D., is a NASA Postdoctoral Fellow on the Space Crop Production Team at Kennedy Space Center in Florida. The UK native's research focuses on on supplementing astronauts' diet with fresh food that is grown in space. "Eventually, we're hoping to replace calories. And as we transition to become more earth-independent, obviously, we want the astronauts to be able to supply, grow more of their own food, so we're less reliant on resupply," he said during his interview for Further Together. Fountain adds that growing plants in space is not easy, and that part of the challenge involves the significantly higher carbon dioxide levels in the International Space Station, where experiments involving plants take place.
