The American-led Cassini space mission to Saturn has just come to a spectacular end. Controllers had commanded the probe to destroy itself by plunging into the planet's atmosphere. It survived for just over a minute before being broken apart. Cassini had run out of fuel and NASA had determined that the probe should not be allowed simply to wander uncontrolled among Saturn and its moons.
