These are the salad days of scientific research on the International Space Station. Astronauts munched on red romaine lettuce. It was the first time this happened. It took place on August 10. They had grown the lettuce in space.
Three astronauts tasted the lettuce. This was after they clicked the lettuce leaves like wine glasses. They added a bit of Italian balsamic vinegar. They also tossed in some extra-virgin olive oil.
Astronaut Kjell Lindgren said it was awesome. And Scott Kelly said it was like arugula. They talked about how the veggies added color to life in space.
Astronauts will need to grow their own food. That is if they want to go farther in space. This was an experiment to test that.
Astronauts grew space station lettuce last year. But they had to ship it back to Earth. It had to be tested. They didn't get to taste it.
