Something new for space travelers: fresh salad!

Assign to Google Classroom

These are the salad days of scientific research on the International Space Station. On Aug. 10, astronauts munched on red romaine lettuce that they grew in space. It was the first time this happened.
 
Three astronauts tasted their lettuce after clicking the leaves like wine glasses. 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. This was an experiment to test that.
 
Astronauts grew space station lettuce last year but had to ship it back to Earth for testing. They didn't get to taste it.

    The bigger question is how these people managed to find places to plant these without making it float away. Also, plants need oxygen just like we do, where could you find a plant that could withstand having no oxygen, water, and sunlight?

    It's difficut to grow vegetables in space because your food might float away in outer space an become space junk.

    It's difficult to grow vegetables in space because they will not stay in place

    This is a cool idea they should be some kind of a robotic waterer so it can water is self.

    That was very interesting because I never knew that someone could actually grow food in space. What is even more interesting to me is that the salad actually taste good. The fact that it grew without soil is so cool! What is crazy is that how they go in space for a long time with oxygen. Finally, I think that it is cool because they grew it with things besides water and dirt.

    Because there is no good soil or oxygen for it to grow. Plants also need water but the soil is going to be hard for the water to soak up.

    It is difficult to grow vegetables in space , because their is no water or soil in space.

    It is hard to grow plants in space because there is no air in space.

    It is difficult to grow vegetables in space because the vegetables will float in the air.

    It is hard to grow vegetables in space because there is no gravity so the plants will float.
