These are the salad days of scientific research on the International Space Station. On Aug. 10, for the first time astronauts munched on red romaine lettuce that they grew in space.
After clicking their lettuce leaves like wine glasses, three astronauts tasted them. They added a bit of Italian balsamic vinegar and extra-virgin olive oil.
Astronaut Kjell Lindgren pronounced it awesome and Scott Kelly compared the taste to arugula. They talked about how the veggies added color to life in space.
If astronauts are to go farther in space, they will need to grow their own food, and this was an experiment to test that.
Astronauts grew space station lettuce last year but had to ship it back to Earth for testing and didn't get to taste it.
