Space Crop Production Controlled Environments

As astronauts venture farther from Earth, and for longer periods, the space food system will increase in importance. Crop production can supplement a packaged diet to provide additional nutrients and dietary variety for astronauts. Several unique challenges exist for growth of plants in microgravity and on other planetary surfaces. Testing with the Veggie and Advanced Plant Habitat (APH) chambers on the International Space Station is allowing us to understand the impacts of gravity and spaceflight on crop growth, nutritional content, and food acceptability, and the importance of plants to astronauts living and working away from Earth. Ohalo 3 is a new capability being developed that will pull from both Veggie and APH as we transition from research approaches to an operational space crop production system to enable human exploration of the moon and Mars.
