This image shows lettuce plants growing in a plant chamber during the preflight testing of Project Rapunzel. The image is captured using near infrared lights rather than white lights. Near infrared light allows plants to be observed during night hours without activating photosynthesis. Project Rapunzel aims to test a special plant chamber and uses computer vision to monitor plant health. Investigation findings may inform ways to automatically monitor plant health and reduce plant stress during long-duration space missions. Credit. UniSQ
