Watch astronauts finally munch on space-grown lettuce
Alien lettuce is a thing. And it tastes like arugula.
In an attempt to experiment with space-grown food, the International Space Station crew recently tried their own lettuce, which was "planted" and grown in the station's "space farm."
The lettuce took 33 days to grow from seeds that were carried onto the station over a year ago, but activated only about a month before the final tasting.
According to the Independent, the farm's technology uses a combination of red, blue and green LEDs to make the lettuce grow in a way that makes the final product look familiar to the one on Earth.
This is an important steps that opens the door to sustainable solution to the food issue for when humans will try to inhabit Mars or embark on another trip far into space.
