2. Io is the most geologically active body in the Solar System.
Why Io?
Io is the most geologically active body in the Solar System.
Volcanic eruptions
Active tectonics
High heat flow
Pele
Io in Eclipse

3. Science Objectives

4. Science Objectives Tidal forces of Io
Distinguish between two basic tidal heating models by measuring latitudinal variations in heat flux and volcanic activity

5. Mission Plan Launch in 2021 Arrive at Jupiter in early 2026
Perform 9 flybys over the course of two years
The final flyby will include a flythrough of Pele’s plume for gas composition

6. Typical Data from One Orbit
Global color imaging at 500m/pixel
Key features imaged at 5-300m/pixel
Pole-to-pole WAV stereo color mapping strips
Imaging of high-temperature activity on night side in 2+ colors
< 100m/pixel; measure liquid lava temperatures
> 80% thermal mapping at km/pixel
Map heat flow and monitor volcanism
Films of active plumes and lava lakes
Color/albedo changes due to volcanic activity
Monitoring of Io, Europa, and Jupiter system

7. Technology

8. Technology New technology limited to DSOC and advanced solar arrays
DSOC = Deep Space Optical Communication
Uses technology previously found on MESSENGER, New Horizons, and the Van Allen Probes
Methods of coping with Jupiter’s radiation
Shielding of sensitive electronics
Radiation tolerant parts
Highly elliptical orbit

9. Additional Modifications
“Dress Rehearsal” for flybys in the asteroid belt
More, larger orbits
Extend the mission by 6 years
Observe Io in the sunlight and darkness
Longer observation of Jupiter
Close flyby of a nearby outer moon

10. New Insights into the Workings of Solar Systems
Planetary processes
Volcanism
Sulfite dynamics in the atmosphere
Tectonism
Magnetospheric interactions
Planetary habitats
Jovian system’s habitable zone is driven by Io’s tidal heating
Could allow us to predict the habitats of other planets in other solar systems
Early building of planets
Io’s high temperature volcanic processes could provide clues on how terrestrial planets evolved and how other planets in other solar systems evolved
