JUICE Science Introduction | D. Titov | SRE-SM | JUICE Kick-off 17.09.2012 |

Congratulations to the JUNO team for the successful orbit insertion! Looking forward to the scientific harvest…

Message on behalf of the JUICE Science Working Team


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…

Presentation Notes

Note: inclination driven by Callisto flybys – to reach high latitude and back


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
