09 Mar 2020 --- The successful cultivation of red romaine lettuce on board the International Space Station (ISS) has been reported by researchers from the NASA Kennedy Space Center in Florida, US. Their research has revealed that despite being grown under lower gravity and more intense radiation than on Earth, space-grown lettuce is free of disease-causing microbes, safe to eat and at least as nutritious as Earth-grown plants. The researchers affirm that their results open the doors for subsequent experiments with other fresh, nutritious crops, as sustainable and safe food cultivation for crew consumption becomes more critical to NASA’s future extended space missions.
