JUICE (for Jupiter Icy Moons Explorer) is space mission to Jupiter launched by the European Space Agency (ESA) in April 2023, to arrive at Jupiter in 2031 and orbit it for 3+ years of observation of the planet and its moons, and eventually to orbit Ganymede. A goal is to characterize the moons' internal structure, especially any ocean layers under the surface. Instruments:

• JANUS - imaging camera.
• MAJIS - visible light/infrared imaging spectrometer.
• UVS - ultraviolet imaging spectrograph.
• SWI - submillimeter spectrometer.
• GALA - laser altimeter.
• RIME - ice penetrating radar.
• J-MAG - magnetometer.
• PEP - particle environment package.
• RPWI - radio observer.
• 3GM - gravity measurement.
• PRIDE - radio transmitter for radio-interferometer observation on Earth.
