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]
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]
European Satellite Navigation Industries, formerly called Galileo Industries until legal action prompted a name change, was a joint venture of the companies Alcatel Alenia Space and Thales (France), Finmeccanica (Italy), EADS Astrium (UK and Germany) and Galileo Sistemas y Servicios (a consortium of seven Spanish companies).
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 ...
In 2010, the think-tank Open Europe estimated the total cost of Galileo from start to 20 years after completion at €22.2 billion, borne entirely by taxpayers. Under the original estimates made in 2000, this cost would have been €7.7 billion, with €2.6 billion borne by taxpayers and the rest by private investors. [53]
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 ...
Europa (Jupiter II), the second of the four Galilean moons, is the second closest to Jupiter and the smallest at 3121.6 kilometers in diameter, which is slightly smaller than Earth's Moon. 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 ...
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]
