There may be proof that the moons maintain oceans of liquid water at depth. Ganymede is the first goal for exploration as it’s the solely moon within the photo voltaic system to generate its personal magnetic subject.
Scientists informed reporters at a briefing on Thursday morning: “Our most important query is whether or not we may discover liveable locations throughout the Jupiter system.
Studying extra about Jupiter will inform us extra about our photo voltaic system and different programs.”

The spacecraft will probably be despatched on a path across the inside Photo voltaic System the place a collection of flybys of Venus and Earth will gravitationally ‘sling’ the craft to its vacation spot.
It’s not anticipated to reach till summer time of 2031. There’ll then be one other eight years of amassing information after which analysing it.
The spacecraft is filled with varied cameras, particle detectors, a radar to map sub-surface options, and a magnetometer – which will probably be used to find extra in regards to the moons’ hidden oceans.
Scientists can even intently monitor Jupiter itself, with astrononers hoping that the information gained about its complicated atmosphere will inform research of different gasoline giants.
