NASA's introduction of LED lights, let astronauts eat vegetables in space.

The United States National Aeronautics and Space Administration (NASA) revealed that the growth of LED lamps are to be used for planting tomatoes and fresh salad leaves, provide food for astronauts on the international space station.

The researchers did a growth chamber in Florida's Kennedy Space Center, the dimming of the LED lighting system, in order to provide the best conditions in the final system installed on the international space station.

The team is to adjust the lighting conditions, in order to optimize the growth conditions of plants, and in the international space station (AdvancedPlant Habitat) advanced plant habitat for these scenes replication, to meet the complex needs of food production in space in the.

The radiation of different wavelengths of light, the growth cycle of a plant can be controlled and accelerated, which can be more frequent or according to the need to harvest plants. The light of special formula can not only optimize the yield and growth time, but also can increase the content of vitamins and nutrients in the plant, and can enhance some taste. LED can not only provide tailored bioactive lighting, but also very effective.

The researchers are using Phytofy of OSRAM RL system, it includes a UV channel, so that researchers can add a short UV, in order to understand how plants react and change. It also includes the irradiance map, so scientists before changing the light settings without irradiance were measured.

In recent years, the possibility of NASA has been exploring in a controlled environment to grow food crops, for long time space mission. A research team led by Wheeler Ray NASA of plant physiologists have been studying how the space on the safe and efficient planting fresh food crops.

Recently, the international space station astronauts to harvest and eat a variety of red lettuce, they are in a Veggie plant growth system.

OSRAM's Steve Graves said: "over the past few decades, many of the world's coolest and most useful invention from NASA scientists. Through the use of our technology, to further promote innovation, this is a kind of glory."
