Nasa astronauts bite into the first vegetables grown in space – video

Nasa astronauts Kjell Lindgren and Scott Kelly, along with Japanese astronaut Kimiya Yui, ate red romaine lettuce grown in space on board the International Space Station on Monday. The harvest comes from Nasa's Veg-01 experiment, aimed at studying how plants grow in orbit in order to give astronauts on possible longer missions in the future the ability to grow their own meals and fresh produce for longer missions
