With the advancement in science and technology, the day is not far when humans will settle on distant planets or may plan a luxurious holiday on the moon.
Growing food in space have many environmental challenges as to build an isolated and confined environment that can aptly recreate growing conditions similar to one on Earth. Professor Mike Dixon and his research team from the University of Guelph in Ontario are working on developing an LED technology that would enable astronauts to grow crops in space efficiently. Dixon, who is also the head of the Controlled Environment Systems Research Facility is conducting experiments to test various wavelengths of light on different plants to observe which works best. The team is working to find the ideal wavelength of the LED light including blue, amber and violet to optimize plant growth and hopefully make agricultural method feasible in outer space. Future manned missions in space would require a constant supply of food and this can be achieved by developing an environment control system and life support system established on plant biology. Moreover, the research is of great importance for astronauts who have been eating freeze dried and processed food in their space mission. If researchers get success in developing this technology, it would also help in growing crops in extreme environmental conditions on Earth from deserts to snow covered land. We've always known that known cucumbers are out of this world, but now they will be, literally.
His experiment will examine the effects of gravity on food harvesting, but the astronauts will sadly not be allowed to eat the cucumbers. The news is likely good for the cucumber industry, which has been battling rumors of food contamination as part of the E. A team of scientists in Norway are set to research the possibility of growing plants and food crops in outer space, it was revealed on Friday. The 10-year project called TIME SCALE will be led by Ann-Iren Kittang Jost, research chief at the Centre for Interdisciplinary Research in Space (CIRiS) at the Norwegian University of Science and Technology (NTNU) in Trondheim. The research team has not yet decided what plants they will try and grow, but are looking at tomatoes, lettuce and soybeans.


It is a complex journey of investigation for the scientists who must learn about the interaction of the plants to their new, very different environment. Researchers from the MELISSA space program believe a closed ecosystem can be fully functional in space by 2050.
The idea is that tomato plants receive water plus food poured into the inner ring, and receive plain water poured into the outer ring. The fine roots around the plant’s stem in the inner ring absorb the nutrients, and the longer roots and tap root absorb the water that has been poured into the outer ring and into the larger grow bag area. Grow bags are a great way to grow tall tomato varieties and by using these pots, will increase the health, rate of growth, the taste and amount of tomatoes that you’ll receive!
A set of grow bag pots will last many seasons and repay their initial expense many times over with lots of good quality and fabulous tasting fruit. Nick’s EbookWhy does keeping the greenhouse windows open help prevent Blossom End Rot?

But arranging enough food supplies for a longer stay is the most challenging part as it occupies considerable room on the spacecraft and sending another spaceship loaded with supplies would be not cost efficient. According to him, there is a lot of potential in LED research, as LEDs can provide considerable light intensity.
On any interplanetary spaceship, resources are limited and therefore, harvesting maximum efficiency is most imperative.
But this would demand science and government research funding to deal before Dixon and his team can grow plants in a climate controlled environment on a distant planet. It would be great for them to eat fresh vegetables and fruit which will provide them with nutrition, as well as psychological support of eating fresh food, said Bob Thirsk, a retired Canadian astronaut.


This would enable more production of food for our growing population, along with reducing of cost. Under the Norwegian research team’s guidance, plant growing experiments were carried out at the International Space Station (ISS). With this goal in mind, the Norwegian researchers’ work is a critical part of giving space explorers the means to survive and eat in a self-sustaining fashion, many thousands of miles away from Earth. This rule isn’t written in stone, but it does help prevent plants from becoming too bushy. BBC Radio 5 live Up All Night spoke to physicist Ian O'Neill who is a space science producer at Discovery News in Los Angeles.
To tackle the issue, researchers around the world are trying to develop a cost efficient method to grow food in space. Infestation by bacteria would be enough to wipe out plants, and unlike Earth, there would be no backups available in space.
LED gives researcher the flexibility to choose and pick elements of the solar spectrum that will be most beneficial for plant growth.
The learning from the lettuce will help researchers in further improving the growth of more nutrients rich plants such as strawberries and cherry tomatoes. Moreover, expert says that it is best to send everything that is essential at the outset, as it is not always possible to send supplies again during such interplanetary trips. The combination of light from LED sources will help in growing substantial quantity of food in outer space in coming 15-20 years. For maximizing the crop yield, fertilizers and pesticides would be used and these have to filter out before the astronauts get exposed to the air and water again.
