Europa was discovered independently by Simon Marius and Galileo Galilei [2] and was named (by Marius) after Europa, the Phoenician mother of King Minos of Crete and lover of Zeus (the Greek equivalent of the Roman god Jupiter). Slightly smaller than Earth's Moon, Europa is made of silicate rock and has a water-ice crust [16] and probably an ...

The name comes from a mythical Phoenician noblewoman, Europa , who was courted by Zeus and became the queen of Crete , though the name did not become widely ...

In December 1997, NASA approved an extended mission for Galileo known as the Galileo Europa Mission, which ran for two years following the end of the primary mission. The focus of this extended mission was to follow up on the discoveries made at Europa with seven additional flybys to search for new evidence of a possible sub-surface water ocean ...

Galileo ' s primary science objectives during E4 were to conduct remote sensing observations of Europa's surface, collect data on the moon's interactions with Jupiter's magnetosphere, and analyze Jovian atmospheric features. It included occultations of the Sun and Earth by both Jupiter and Europa, which provided an opportunity to search for ...
