NASA announced that Jupiter would soon be explored during a mission in which the budget has been estimated at several billion dollars.

NASA and the European Space Agency (Esa) will join their resources for the project. They plan to send two probes, one conducted by each agency, to study in detail the gas giant and its four satellites.

It will take approximately 6 years to reach Jupiter. With investigations launched in 2020, two different sites, therefore the probes reach Jupiter in 2026. Three years on site would be devoted to the study required.

The probes would spend almost a year orbiting satellites Ganymede and Europe. The engine NASA would consider Europe and the possibilities it home life, while the ESA study Ganymede, Jupiter's only satellite known to have its own magnetic field. Callisto and Io will also be studied: Callisto has an ancient crater on the surface, providing information about the history of the solar system, while qu'Io is still active volcanic level.

The two agencies should undertake more detailed studies before they officially launch the mission. Engineers at NASA and ESA also an ambitious mission to Titan, satellite of Saturn. Ed Weiler, Associate Administrator at NASA, said that "even if the system of Jupiter was selected to begin a mission to Saturn is clearly a priority for the scientific community."
