Astronauts are about to eat a crop of romaine lettuce that they have grown entirely from seed on ISS.

The story is important as it indicates that the engineering to grow plants in space is continuing to improve. The article however is very wrong when it says that this will be the first salad grown and eaten in space. Russian astronauts have been working on this problem on their space stations since the 1970s, and in at least one case — which was captured on video almost a decade ago — have eaten space-grown lettuce. (I wrote about this event for Air & Space back in 2003.)
