LED light box successfully planted space Bai daisy
Chinese vegetables are looking at the stationAt the time of the January 17th, at the International Space Station, 402 kilometers above the human head, a flower was opened. This is the American astronaut Scott Kelly (Scott Kelly) in the ground science team support, cultivated a hundred daisies, she is the first human flowers in outer space cultivation. For the day and night to take care of her astronaut Kelly, she really like the Antoine de St. Eku Su Perry pen that is the little prince of the rose, unique, beautiful and proud.However, things are far from looking so gorgeous. Like a beautiful woman twists and turns of life, I also want to share with you the flowers behind the wonderful story.This is a wonderful picture, the background is the earthSpace a flower home space station plant laboratory LED light boxKelly in the push on the release of the blooming hibiscus picture, to look at this “space a flower”: mosaic green, flowers into a goose yellow, orange, orange red gradient state. Fresh and dripping to the color and graceful shape, and the earth on the difference is not too big.But because of the space station zero gravity, their petals are more open, like to make every effort to stretch in the waist, almost lying flat, not like the flowers on the earth as the formation of subtle curvature. This space is the place where the growth of the bacon, is the international space station plant laboratory LED light box, which contains the red, blue and green LED lights consisting of a set of cultivation system.The plant laboratory was founded in May 2017 and is not only designed to study the growth of plants in outer space, but also to explore how astronauts can eat fresh vegetables in space.So far, the laboratory has planted two crops.The first crop is red lettuce. “Two of the first boiled lettuce were dead, so the astronauts treated the next batch with caution,” says Trent Smith, project manager for the plant lab. Two batches of crop sesame seeds, astronauts pay special attention to adjust the water supply. Most of the sesame grows. Flight crew in a month after the harvest day, they eat their own in the space station out of the sesame seeds.Bright and easy to blossom of the daisy will become a space plant breeding samplesThe third crop is the durum.Zhejiang Forestry Science Research Institute Dr. Yang Shaozong told reporters that the two hundred pear is a variety of South America, very easy to flowering, flowers bright colors, mainly as ornamental plants. She can also eat, generally used to make salad.
However, these hundred daisies are selected for planting outside the sky, not because of their value, but because they can help scientists better understand how plants in the case of microgravity flowering. They are the first flowering plants that scientists have planted in space.“Pisces and red lettuce are very different.” Smith said, “Bischium is very sensitive to environmental parameters, especially for changes in light, and their growth cycle is longer than that of red lettuce, which takes 60 to 80 days.“Bischium is very easy to bloom, if you let out a flower in space, scientists can slowly explore the special environment, the flowering conditions of plants, then the results of the food to plant, it is relatively easy.” , Which is why the cultivation of Picea davidii, will become the next battle of tomato and other food crops growth samples.Space plants help mankind go further Chinese vegetables are expected to nurture in the space station“Plants can indeed grow long-term in isolated, restricted, and extreme environments, such as man-made environments.” NASA Human Research Program scientist Alexandra Whitmire says the astronauts plan to The space station planted a series of other vegetables, and is expected in 2018 to cultivate short tomatoes.NASA says tomato cultivation is important for the Mars exploration program because astronauts have to grow their own food without contact with the earth.If humans are successful in planting plants in space, they can expand on Mars and the moon base on a large scale. “If the astronauts can grow their own food, then in the future outer space mission, the astronauts will not rely too much on the supply of the earth to supplement, not afraid of outer space lonely environment – because there is such a biological companion.” Whitmai Said.
