Veg-01 Experiment Daily Check

ISS040-E-007672 (5 June 2014) --- One of the Expedition 40 crew members on the International Space Station photographed his hand working with the Vegetable Production System (Veggie) recently added to the orbital outpost. The experiment deals with the growth and development of ‘Outredgeous’ Lettuce (Lactuca sativa) seedlings in the spaceflight environment and the effects of the spaceflight environment on composition of microbial flora on the Veggie-grown plants and the Veggie facility. The purple light is the
wavelength that is supposed to best promote photosynthesis and growth for the plants.
