iss052e002352 (6/12/2017) --- A view of NASA astronaut Jack Fischer replacing the European Modular Cultivation System (EMCS) Experiment Containers (ECs) with new ECs prepared for the Seedling Growth 3 experiment. Seedling Growth-3 is the third part of the Seedling Growth Experiment series, using the plant Arabidopsis thaliana to investigate the effects of gravity on the cellular signaling mechanisms of light sensing in plants (phototropism), and to investigate cell growth and proliferation responses to light stimulation under microgravity conditions.
