NASA initially pioneered these techniques on the ground by building the country’s first vertical farm. Inside a decommissioned hypobaric chamber left over from testing the Mercury space capsule, technologists stacked rows of hydroponic trays like bookshelves against the walls. Then systems for lighting, ventilation, and circulating water were added using off-the-shelf parts. Various crops were planted on the stacked trays to test how well they would grow in water and without the benefit of sunlight or open air. This innovative approach to farming created a foundation for the industry of controlled environment agriculture, or CEA.

CEA combines plant science and environmental control to optimize plant growth and maximize efficiency, frequently incorporating vertical growth structures. Technology enables the filtering of contaminants from crop water and delivers precise nutrient balances. Artificial lighting provides only the necessary wavelengths at the right time, intensity, and duration, while environmental controls maintain ideal temperature and humidity. This approach could help feed burgeoning future generations, said Nate Storey, chief science officer at Plenty Unlimited, one of several companies building on NASA’s plant-growth research.
