MUSIC Lettuce Orbit Earth — A New Form of Life Takes Root on the International Space StationPresented by Science Nasality×39’s spring, and all around the Northern Hemisphere gardeners replanting seeds, tilling soil, and watering crops. Imagine a gardener's surprise, however, if water from the hose, instead of hitting the soil and sinking in, floated up to the sky. Or if the soil itself rose up from the ground and fled the garden. That's exactly the kind of dilemma astronauts aboard the International Space Station have faced for years. Without gravity, how do you make your garden grow? The situation is even more confusing for plants. In a weightless environment, up and down has no meaning, so roots grow in odd, chaotic directions. Shoots that emerge from the soil in search of the sun find, instead, a cold metallic lamp that never rises or sets. And needless to say, it never rains inside the space station. On April 18th, SpaceX's Falcon rocket, carrying the Dragon cargo spacecraft blasted off from Cape Canaveral in Florida with a possible solution to these problems.quot;We call it 'Veggie', *?? Says Iowa Massey of NASA's Kennedy Space Center.quot;It's a plant growth chamber designed to make gardens thrive in weightlessness.quot;Massey, who leads the Veggie science team, has been working on the project for years. Veggie's heritage traces back decades to experiments with plant son board the Russian space station Mir and NASA×39’s space shuttles. In all that time, NASA astronauts have never tasted home-grown food in space-but that could soon change.quot;Our first crop will be a variety of lettuce called 'Outrageous,'” says Massey.” It is delicious.quot;Veggie solves the problems of weightlessness using 'plant pillows.'quot;Basically, these are bags of quote, 'space dirt×39; and slow-release fertilizer, *??explains Trent Smith, the Veggie project manager at Kennedy.quot;Wicks inserted into the bags draw water into the soil where it cannot float away.quot;In addition to guiding water, the wicks act as a kind of gardening stake.quot;The wicks are where we glue the seeds, continues Massey.” We have to be very careful to orient the seeds so that roots grow 'down' into the soil and shoots pop out of the bag.quot;When the shoots emerge, they find an array of LEDs shining overhead, providing light for photosynthesis and a sense of direction to keep the shoots moving quot;up.” The bellows-like walls of the chamber allow it to expand to make room for the growing crop. Pictures of Veggie often show the chamber flooded with a mixture of red and blue light. That's the color of light plants use most for photosynthesis.quot;We're just giving them what they want, says Smith. Under a purplish light, plants appear gray and unappetizing. Quot;Who wants to look at that?” asks Massey. Astronaut gardeners can switch on green LEDs as well. Adding that color to the red-blue mix produces white light and displays the garden to better effect. The appearance of the garden is...
