Fresh food on the ISS

For the first time, space-grown fresh food was eaten on the International Space Station (ISS). It took 33 days to grow the red romaine lettuce, which the astronauts munched on. Being able to grow food in space will help sustain longer exploration missions. This is not the first time food has been grown on the ISS. Lettuce was grown there last year as well, but it was not eaten. It was returned to Earth, and was analyzed to make sure that it was safe to eat.

The ISS is a large research facility in space. It hangs around 250 miles (400 km) above the Earth’s surface. It goes around our planet once every 90 minutes, and it can accommodate up to 6 people.

You can watch a video of the ISS crew eating the lettuce here.
