Strawberries May Be Ideal Crop for Space Farms of the Future
Strawberries in Space via Flickr/ Paraflyer Astronauts on long space voyages would probably get pretty tired of freeze-dried meals, so scientists have long been trying to figure out how to grow space food to supplement their diets. According to researchers at Purdue University, strawberries may be one space-friendly crop. They say a low-maintenance strawberry cultivar called Seascape would do pretty well in space. It produces fewer berries than other cultivars, but they're bigger and just as tasty. Growing plants in space comes with several challenges, not the least of which is providing artificial light. Artificial-sunlight lamps need lots of power, and they generate heat, too, so a spacecraft or space base would need enough power to cool things down. There are no winds or insects to pollinate the plants, which is especially problematic for flowering fruits like tomatoes and strawberries. Roots grow differently in low-gravity environments. And water is a...
