As I mentioned a few weeks ago, NASA astronaut Steve Swanson has been doing some gardening on the International Space Station, growing ‘Outredgeous‘ red romaine lettuce in the new VEGGIE gardening system. This inaugural experiment, called Veg-01, is partly a test of the hardware and partly to see whether space-grown crops will be safe to eat. After all his hard work, Steve doesn’t get to eat his lettuce – it has to be returned to Earth for testing. If the lettuce is proved safe, a second batch of lettuce can be grown and eaten later in the year. This would be the first mouthful of ‘homegrown’ food to be consumed in space, and NASA have produced a great video explaining the VEGGIE project:
