Due to arrive in 2030, the spacecraft will periodically dive through Jupiters radiation to flyby Europa to capture information before ducking out again.
The radar instruments will determine the depth and salinity of Europas ice and search for hotspots where the underground ocean could be seeping out!

Launch date: Mid-2022
Overview:
Launching via the Ariana 5 rocket, and due to arrive in the Outer solar system in October 2029, the JUICE satellite will flyby not just Europa by Jupiter and the other three largest moons too, to search for habitable spots such as subsurface oceans, much like the Europa Clipper mission!
