Mars, the red planet, we have long wondered if it has ever sustained life. Some have dreamt of walking on its surface but more than four decades after they landed on the Moon, NASA are imagining a two year voyage across space to Mars but to do it, they require new rockets on a new scale, a new way of surviving in space and a new bread of astronaut. To finally complete a mission of this scale would be the fulfillment of one of our grandest dreams. Is this however a dream NASA can deliver?
