Year 1972 - Pioneer 10 becomes the first spacecraft to enter the asteroid belt. On 3 December 1973 it passed within 130,354 km (81,000 miles) of Jupiter's cloud tops , obtaining the first close-up images of the planet and charting the intense radiation belts and magnetic field. Pioneer 10 is headed in the general direction of the star Albebaran in the constellation Taurus. At a distance of 68 light years, the spacecraft travelling at 132,000 kph (82,000 mph), will take about 2 million years to reach it

1979 - Voyager 2 makes its closest approach to Jupiter. The spacecraft passes within 570,000 km (350,000 miles) of Jupiter's cloud tops and then heads for Saturn. High resolution photos of Jupiter's moon Europa lead to the belief that the moon is completely covered with a deep water ocean capped with a surface ice layer less than 30 km (18 miles) thick
