Message on behalf of the JUICE Science Working Team Congratulations to the JUNO team for the successful orbit insertion! Looking forward to the scientific harvest
The JUICE origins: the COSMIC VISION PROGRAM 2015-2025 Addressing the questions raised by the european scientific community in Astronomy, Solar System exploration and fundamental physics Large/medium/small size missions to be launched between 2015 and 2025 JUICE evolved from former EJSM concept JUICE: first L-class mission, adopted by end 2014
From Cassini to Juice the icy moons as potential habitat

Icy Moon Flybys: summary 2 EUROPA @ 400 km 12 GANYMEDE @ 300-50,000 km 14 CALLISTO @ 200-3,500 km
Trajectory: Cruise Phase 5 6 1 3 2 4 7
Trajectory: All orbits viewed from above 5 6 1 3 2 4 7
Science planning activities 4 science working groups: responsible for top level science planning mission segmentation/resource distribution
High level science planning on-going Mission segmentation by science themes by the Working Groups Energy reduction Europa High latitude Low energy Orbiting Ganymede
Europa flybys: analysis of detailed operational scenarios Ground tracks optimized to fly over 4 of the 8 regions of interest with good illumination conditions and study leading-trailing dichotomy S/C sub-point velocity wrt surface at CA: 3.25 km/s
Detailed operations analysis at Europa
JUICE and the NASA Europa mission Both projects decided to use the planetocentric East coordinates for the Jovian satellites, so both projects will be consistent.
JUICE and Juno Juno related scientific topics that should be very useful for JUICE: Updates in the radiation environment (spacecraft and instrument designs) New findings about Jupiter s magnetosphere and plasma interactions between the Galilean satellites and Jupiter; updates in the magnetic field model (science planning) New findings about Jupiter s atmosphere (science planning) Jovian satellites ephemerides (TBC) JUICE will pick up on Juno science almost exactly one Jovian year after Juno ends Shared heritage and complementarities between Juno and JUICE
