IVO Ariela Berg Rachel Inderhees Io Volcano Observer

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

Science Objectives

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

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

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 0.1-10km/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

Technology

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

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

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
