Abstract A promising avenue to address these questions is a new spacecraft mission making multiple close flybys The Io Volcano Observer (IVO) Discovery mission of Io, combined with research and analysis motivated proposal [1] has been re-focused in 2019 towards by the mission. IVO will address all of these understanding tidal heating as a fundamental questions, while still within the constraints of NASA planetary process. To “Follow the Heat”, IVO will Discovery program. IVO will characterize volcanic determine how heat is generated in Io’s interior, processes (Q1); test interior models via a set of transported to the surface, and how heat and mass are geophysical measurements (coupled with laboratory lost to space. experiments and theory; Q2 and Q3); measure the total heat flow and orbital evolution of Io (Q4); and 1. Tidal Heating analyze mass loss processes (Q5). No new technologies are required for this mission, which Tidal heating is key to the evolution and habitability leverages advances in radiation design and solar of many worlds across our Solar System and beyond.
