ISS astronauts bite into space-grown lettuce

Astronauts on board the International Space Station (ISS) have tasted space-grown lettuce.

The red romaine lettuce leaves were grown entirely by the team and it marks the start of the "veggie project" that will see more food grown in space.

NASA scientists say fresh food will have a positive impact on the astronauts' health.

Astronauts have been growing crops in space for years for research, but this is the first time they have been allowed to eat their produce.
