Cassini-Huygens, the international mission to Saturn, has successfully entered into orbit around the planet.
In a near-perfect operation, the £1.8bn probe slowed down using its main engine, was caught by Saturn's gravity, and started orbiting the ringed world.
Bob Mitchell, head of the Cassini programme, said: "It was the result of a lot of work by a lot of people."
The spacecraft has travelled for over six years, and will study the planet and its 31 moons for four years.
