ESA Euronews: Growing food in space.

Is is possible to produce food to eat and air to breathe while in space? The short answer: it's not easy, but it can be done. Right now, if you're an astronaut, you're given pre-prepared food that was cooked on Earth and sent into space on a rocket. But if humankind wants to realise its ambition of travelling much further into the solar system it needs to find ways to create food and air while surrounded by the nothingness of space.
