European Space Agency astronaut Paolo Nespoli has said the drinking water on the International Space Station tastes better than that on Earth, despite being recycled.

He was answering a question sent in by Buzz Purdy, who wanted to know how important hygiene was on board the station, and what it was like drinking coffee knowing where the water had come from.
