For centuries, humans have looked up at the night sky and wondered what it's like deep in space, far from Earth -- and now we've begun to find out. We've landed on the moon, put robots on Mars, and sent space probes billions of miles to explore the far reaches of our solar system. Told in richly detailed cutaway illustrations by Stephen Biesty and friendly, engaging writing by Martin Jenkins, here is the enthralling story of how we made the great leap into space and what we've discovered there. Find out what life is like on the International Space Station, what the chances are that we will ever settle on Mars, where in the solar system we might find alien life, and why visiting other stars will almost certainly remain a dream. Budding astronomers, junior astronauts, and anyone who has ever gazed up at the stars in fascination will pore over this beautifully intricate yet accessible glimpse of the infinite wonders of space.
