Caution, Land Gardens: Space becomes a distant future for growing fresh vegetables.
In 2015, after the successful planting of lettuce in the International Space Station (ISS), it could be the yeast that would leave beans in 2021, said the Norwegian University of Science and Technology's press release. Other salads that are essential in the area can also be cultivated in space, and the nutrition they need to live on other planets would provide cosmonauts and other intergalactic travelers.
"The dream of each astronaut is to be able to eat fresh food: strawberries, cherry tomatoes, or tasty. In fact, it will be possible," said Silje Wolff, physiologist at the NTNU Interdisciplinary Research Space Center, in a press release. "We see a greenhouse with several vegetable varieties".
Wolff completed an experiment that worked on lettuce in a space environment. The lettuce was planted in artificial terrain derived from the lava-edge and was placed in high-tech plants that controlled plant nutrients. The purpose of the experiment was to grow lettuce in each one of the head that was made up of foods of plants.
When plants observed climate-regulated growth chambers, Wolff noticed that nitrogen was used as a nutrient. Wolff studied how different doses of food affecting the water intake of plants.
"Plants can have a" smell "of these nutrients in a way. When nitrogen concentration is too small, the plant will absorb more water, and so it will achieve more nitrogen to achieve optimal levels," said Wolff at the press conference. "The plant has a mechanism activated when it is suitable for nitrogen levels, then adjusts nitrogen and water absorption."
The next step in Wolff's research is how to grow beans in space and how nutrients and water absorption in the plant can be absorbed. Although the absence of gravity can not be simulated in the Earth's lab, the beans will be spun-off at space stations. The centrifugal will rotate to create gravity levels for the legates.
"In order to get something that grows in space, art can be transferred to our plan," Wolff said at a press conference. "This creates the microgravity conditions of the space station and the configuration that generates Earth's 1-g force."
We should wait a couple of years for beans and other vegetables to grow in space, but once it's done, it will be exciting to see plants planted from the outside of our planet.
