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

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

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
