What could be more appetizing after a long flight to Mars than sinking one's teeth into a juicy red tomato grown in pee?

The BBC reports that the first thing a visitor sees upon entering Jens Hauslage's tiny office in the German space agency DLR is a fish tank filled to the top with urine. In the middle of the tank, a pair of clear plastic cylinders house a tomato plant each.

But are they edible, wonders the reporter? Absolutely, according to Hauslage.

How edible? After taking a bite, the reporter notes, "To be brutally honest, it’s not the nicest tomato I have ever tried: the skin is a little tough and the taste is slightly bitter. But it is, nevertheless, a healthy, edible tomato."
