LED lighting technology can help star trek to grow food in space

According to foreign media reports, Mike from University of Guelph, Dixon is leading a research team dedicated to the development of a LED technology, this technology allows astronauts to grow food in space at the most efficient speed.

If we want to carry out manned missions to Mars and beyond the planet, we must overcome many important technical obstacles. One of the problems we have to face is to build a spaceship that will send astronauts to the solar system. The journey to ensure there is enough food for astronauts eat almost is a daunting challenge.

Professor Dixon is the head of the controlled environmental systems research facility, which is also the site of the experiment. The objective of this study was to determine which specific wavelengths were best for the growth of various plants. The resources of any interplanetary mission must be limited, so energy efficiency is the key. The smaller the weight of the space, the better to carry out the interplanetary mission only to carry the necessities, and astronauts can not go to the food store in the middle of the trip to mars.

The research team is studying the use of LED to optimize the technology of plant growth, the most important thing is the effectiveness of LED lighting. Because when resources are scarce, you can get a lot of photons through less energy. The LED lamp can also be used to produce special wavelengths necessary for plant growth,

The researchers tested lettuce in the experiment because it is easy to grow and grow fast. Researchers will use the results to improve the growth of more nutritious crops, such as strawberries and Cherry Tomatoes. Dixon believes that the strange method of LED light source will be 15 to 20 years to be applied, so that astronauts in space planted a large number of objects, perhaps for the Mars mission is still too late.
