Back in the 1980s, NASA's Voyager spacecraft made a brief flyby of Saturn's moons, providing us with a tantalising glimpse of new worlds. Now, the Cassini mission has finished the job, providing us with high-resolution, colour maps of Saturn's six icy moons.

NASA's Orion spacecraft, designed to ferry the first humans to Mars, lifts off from Cape Canaveral on Friday morning. Orion reached speeds of 20,000 mph and travelled 3,600 miles from Earth before a successful splashdown in the Pacific. [Bill Ingalls/NASA]
