Veggies in Space: Salad Crop Production on the ISS

NASA is currently testing Veggie, a low mass, low energy, salad crop production system on the International Space Station (ISS). Veggie grows crops with LED lights using ISS cabin air and passive watering that has presented challenges in microgravity. Initial tests included red romaine lettuce and zinnia, with testing of Chinese cabbage, and tomatoes planned. A goal is to add supplemental salad foods to the astronaut diet as we prepare for a future journey to Mars.
