The Solar System - first stops in space. Voyage through the Solar System. Skim the seething face of the Sun. Watch a double sunrise on Mercury, the volcanic hell of Venus, the serenity of beautiful blue Earth, the far side of the Moon. Explore Mars, where next we'll walk, seek life on Jupiter's Moon Europa and swoop through the gossamer rings of Saturn. Beyond Uranus and Neptune, discover Pluto - perhaps not a planet at all? Could a comet or an asteroid destroy life on Earth like the space-rock that slew the dinosaurs?
