Astronauts grow plants on the International Space Station. Recently, they harvested, or picked, alfalfa there. Alfalfa is a small green plant. They took the plants and roots out. They also took photos of them. Then they put them in a cold place. Scientists will study them later. This may help astronauts grow food. (nasa.gov)
It is like a small garden at home. You give plants water and light. You watch them grow every day. Then you pick them when ready. In space, this simple job is harder. However, fresh plants can help the crew. Green food can also feel like home.
