For the first time, the NASA managed to grow edible vegetables in space and particularly red romaine lettuce. On the international spatial station and thanks to their vegetables production system called Veggie, the unit was able to make fresh salad in a kind of cabin providing a controlled temperature, a lighting with red, green and blue LED lights and enough nutrients. According to Dr. Ray Wheeler (who works at the Kennedy Space Center, in Floride), the idea of growing plants in space thanks to LED lights appeared at the end of the 90’s. The project comes out finally today.
