For the first time, produce grown in space was harvested by NASA astronauts for an out-of-this-world salad, NBC News reported.
"It tastes good. It tastes kind of like arugula," said astronaut Scott Kelly, while chowing down on the "Outredgeous" red romaine lettuce in his mouth aboard the International Space Station on Monday.
Half of the lettuce was harvested for consumption and half was frozen so it could be sent back to Earth for analysis. NASA hopes that this Veg-01 experiment could be the first step toward creating self-sustaining food supplies for a trip to Mars or future deep-space missions.
