Astronauts living at the International Space Station have taken their first bites of space-grown lettuce, in another step toward enabling human missions to Mars.
NASA astronaut Kjell Lindgren, said the red romaine lettuce - grown in a special box aboard the orbiting outpost - was amazing, while another astronaut, Scott Kelly, said it tasted good, like the salad herb rocket.
One of the astronauts used a small bottle to spread olive oil and balsamic vinegar on his leaf.
Jim Mora talks to Paul Zamprelli of Orbitec, who manufacture the grow boxes, which grow lettuce 26 times faster in orbit than it grows on earth. Growing food on board also contributes to the environmental and life support systems needed to sustain life in space.
