After a journey of over three years, Voyager 1 has reached Saturn-800 million miles from Earth. Last year the spacecraft bypassed Jupiter and sent back the most spectacular images ever seen of the planet and its satellites. Now it has arrived at Saturn and is transmitting pictures and scientific information about this most beautiful planet. Patrick Moore reports from the Mission Control Centre for Voyager at the Jet Propulsion Laboratory in Pasadena, California, with Dr Garry Hunt , and discusses the results with the American scientists responsible for the mission.
