Eat lettuce grown in ISS

23 Aug, 2015

NASA astronauts on the International Space Station eat red romaine lettuce, which they freshly harvested from the orbiting lab’s vegetable plant growth system. The space garden snack marks the first time NASA had cleared its astronauts to eat what they grew. Before eating, they clean the lettuce with citric acid-based sanitizing wipes.

Lindgren: That’s awesome
Yui: I like that
Kelly: It tastes like arugula

The three save a few leaves for their Russian cosmonaut crewmates, two of whom are out on a spacewalk. Half of the harvest is frozen on the station so it can be returned to Earth for scientific analysis.
