For freshly grown produce, space is truly the final frontier.
But even astronauts will soon be able to abide by their mothers’ exhortations to eat more veggies.
Following the much-celebrated harvest of a head of romaine lettuce aboard the International Space Station (ISS) in 2015, astronauts’ vacuum-packed vittles may be kicked up a notch as early as 2021 with the addition of space-grown beans. More salad fixings are also in the cards. After that? The galaxy’s the limit.
“The dream of every astronaut is to be able to eat fresh food like strawberries, cherry tomatoes or anything that’s really flavorful,” Silje Wolff, a plant physiologist at the Centre for Interdisciplinary Research in Space (CIRiS) at the Norwegian University of Science and Technology (NTNU), said in a statement. “Someday that will certainly be possible. We envision a greenhouse with several varieties of vegetables.”
