In today's newspaper, I read that US astronaut Sunita Williams is trying to grow vegetables in International Space Station
Why does she want to grow vegetables in space ??
Fresh food is healthier than packaged food.
Growing food in space is important for astronauts 'health on long mission.
Growing food is a step towards living in space.
It would reduce the amount of food astronauts need to bring.
Lettuce is the first food grown on space.
Lettuce was chosen as it is easy to grow and nutritious.
