There are many more worlds in our solar system than just the planets. The mysterious moons of the gas giants may hold much more than we ever imagined. Each one is unique, and each one deserves a scrutinous eye.
In the cold, dark expanse of our solar system, beyond the asteroid belt, lie the giant planets. Some can be seen with the naked eye, others have been visited by our camera. What secrets do they hold?
The sun bathes our planet in warmth and light. It powers the machinery of nature, our weather, and it encourages and sustains life on land and at sea. We study it closely, and it can reveal the secrets of all other stars.
Our modern-day itch to find out what lies out beyond our atmosphere is rising again. The frontiers of space exploration are expanding as scientists debate a range of future missions: a return to the Moon, manned flights to Mars, robotic missions to Titan and Europa, or mining asteroids. This expansive series shows that this grand quest is driven as much by technology as our attitudes toward Earth.
