Astronauts are given the opportunity to go where no man has gone before. Can you imagine the idea that your home isn’t just a bus journey away, isn’t a train journey away, it isn’t even the other side of the ocean or on a different continent, its on a different planet. There is only one way back and if that fails you wont be going home, ever. Do you think Neil Armstrong ever thought, ‘I hope i didn’t leave the iron on?!’ - david saunders
