Radish plants are growing inside the Advanced Plant Habitat (APH) ground unit inside a laboratory in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida on June 13, 2019. The plants are being grown as part of a science verification test for PH-02, a Space Life and Physical Sciences Research and Applications-funded experiment which seeks to determine the effects of spaceflight on radishes. The APH is a highly automated plant growth chamber with 180 sensors and is able to closely regulate variables related to plant growth.
