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. [21] Starting in May 1999, Galileo used four flybys (20 to 23) with Callisto to lower its periapse, setting up a chance for it to fly by Io twice in late 1999. [2]
In 1605, Galileo had been employed as a mathematics tutor for Cosimo de' Medici. In 1609, Cosimo became Grand Duke Cosimo II of Tuscany. Galileo, seeking patronage from his now-wealthy former student and his powerful family, used the discovery of Jupiter's moons to gain it. [6] On 13 February 1610, Galileo wrote to the Grand Duke's secretary:
Europa Clipper (previously known as Europa Multiple Flyby Mission) is a space probe developed by NASA to study Europa, a Galilean moon of Jupiter. It was launched on October 14, 2024. [15] The spacecraft will use gravity assists from Mars on March 1, 2025, [10] and Earth on December 3, 2026, [11] before arriving at Europa in April 2030. [16]
The primary mission concluded on December 7, 1997, but the Galileo orbiter commenced an extended mission known as the Galileo Europa Mission (GEM), which ran until December 31, 1999. By the time GEM ended, most of the spacecraft was operating well beyond its original design specifications, having absorbed three times the radiation exposure that ...
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 ...
It included the "Galileo Europa Mission" and "Galileo Millennium Mission", with numerous close flybys of Europa. [146] In 2007, New Horizons imaged Europa, as it flew by the Jovian system while on its way to Pluto. [147] In 2022, the Juno orbiter flew by Europa at a distance of 352 km (219 mi). [17] [148]

Galileo discovered the four brightest moons of Jupiter, Io, Europa, Ganymede and Callisto in 1610. Having determined their orbital periods, he proposed in 1612 that with sufficiently accurate knowledge of their orbits one could use their positions as a universal clock, which would make possible the determination of longitude.
