Inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida, a plant biologist prepares to harvest radish plants growing in the Advanced Plant Habitat (APH) ground unit on June 13, 2019. The radishes are being harvested as part of a science verification test. The APH is currently the largest plant chamber built for the agency in use on the International Space Station. It is an autonomous plant growth facility that is being used to conduct bioscience research on the space station with the goal of enabling astronauts to be sustainable on long duration missions to the Moon, Mars and beyond.
