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.

A view of radishes growing in the Advanced Plant Habitat (APH) ground unit inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Dec. 14, 2020. The radishes are a ground control crop for the Plant Habitat-02 (PH-02) experiment. The experiment also involves growing two similar radish crops inside the International Space Station’s APH. NASA astronaut Kate Rubins harvested the first crop on Nov. 30, and the second harvest aboard the orbiting laboratory is planned for Dec. 30. Once samples return to Earth, researchers will compare those grown in space to the radishes grown here on Earth to better understand how microgravity affects plant growth.
