The proposed design and payload will transform our understanding of this unique world and how tidal heating shapes planetary worlds across the cosmos. A student-built wide-angle camera (WAC) based on Europa Clipper's EIS WAC camera is also being considered in the Phase A study. Io Volcano Observer (IVO) is a robotic space exploration mission concept that, if approved and launched, would orbit Jupiter and perform at least nine flybys of Jupiter's moon Io. These results are expected to have direct implications for the thermal history of Europa and Ganymede as well as provide insights into other tidally heated worlds such as Titan and Encela… The theme connecting the diverse science to be done at Io is "Follow the Heat.". Io Volcano Observer (IVO) is a robotic space exploration mission concept that, if approved and launched, would orbit Jupiter and perform at least nine flybys of Jupiter's moon Io. Primary Mission: 9 Io flybys from Jupiter orbit over two years. Io Volcano Observer (IVO) is a concept under study for NASA's Discovery & Scout Mission Capability Expansion (DSMCE) proposed in 2008, 2009 and 2010 to the Discovery Program, but IVO was not selected. The good news comes just in time for Valentine’s Day. IVO is similar to the Io Orbiter concept suggested for the New Frontiers Program by the 2013–2022 U. S. National Research Council Planetary Science Decadal Survey. IVO is a low-cost, outer-planet mission that would explore Io's active volcanism and impact on the Jupiter system as a whole by measuring its global heat flow, its induced magnetic field, the temperature of its lava, and the composition of its atmosphere, volcanic plumes, and lavas. A. S. ... Volcanic eruption style: How lava erupts and cools is key to understanding how Io loses heat. [1] The time and location of closest approach are carefully optimized to obtain the clearest observations of Io's induced magnetic field, libration amplitude, and gravity field. Io is the best place to study the Its volcanic activity was discovered in 1979 by Voyager 1 imaging scientist Linda Morabito. On Earth, plate tectonics mixes large slabs of cold oceanic crust into the warm mantle. A proposed mission called Io Volcano Observer (IVO) would visit Jupiter ’s moon Io, which is a true volcanic wonderland with hundreds of erupting volcanoes gushing tons of molten lava and sulfurous gases at any moment. There is a continuing debate about where the tidal heat is produced within Io with some observations suggesting that it is primarily in the shallow mantle while others suggest that the heating is broadly distributed. If selected, the Io Volcano Observer, or IVO, mission will orbit Jupiter and make 10 close flybys of its moon Io – the most volcanically active world in the solar system – to determine if the moon has a magma ocean hidden beneath its vibrant, pockmarked surface.

Io presents a rich array of inter-connected orbital, geophysical, atmospheric, and plasma phenomena and is the only place in the Solar System (including Earth) where we can watch very large-scale silicate volcanic processes in action. [1] Following a flyby of Io on its way in, the Io Volcano Observer would execute a Jupiter orbital insertion burn to go into an inclined orbit around Jupiter. The IVO data may also improve our understanding of magma oceans and thus the early evolution of the Earth and Moon. Climate & Space Assoc. University of Arizona: Principal Investigator Regents’ Professor Alfred McEwen, science operations, student collaborations Johns Hopkins Applied Physics Lab: Mission and spacecraft design, build, and management; Narrow-Angle Camera; Plasma Instrument for Magnetic Sounding The Io Volcano Observer (IVO) is a proposal for a Discovery-class mission that would launch in 2021. On February 13, NASA announced the selection of the Io Volcano Observer as one of the four proposals for future Discovery-class missions to move a step closer to launch later this decade. IVO was again proposed in February 2015 for Discovery Mission #13. It is also unclear how much of the heating is from deforming solid rock versus pushing liquid magma around. Io Volcano Observer, IVO (Спостерігач вулканів Io) запропонована роботизована місія, яка, якщо буде схвалена і запущена, здійснить дослідження Юпітера і його супутника Io. A proposed mission called Io Volcano Observer (IVO) would visit Jupiter’s moon Io, which is a true volcanic wonderland with hundreds of erupting volcanoes gushing tons of molten lava and sulfurous gases at any moment. [6][7] In 2020, IVO was selected along with three other Discovery proposals for further study, with one or two expected to be selected to fly. [1] The main science goals are to understand (A) how and where tidal heat is generated inside Io, (B) how tidal heat is transported to the surface, and (C) how Io is evolving.

The main science goals are to understand (A) how and where tidal heat is generated inside Io, (B) how tidal heat is transported to the surface, and (C) how Io is evolving. IVO will also sample the complex mix of ionized and neutral molecules of plasma and gas around Io. AS McEwen, E Turtle, L Kestay, K Khurana, J Westlake, etal. THE IO VOLCANO OBSERVER (IVO). A. S. McEwen1, L. P. Keszthelyi2, K. E. Mandt3, and the IVO Team.1LPL, University of Arizona, 2U. Io Volcano Observer (IVO) was proposed to the NASA Discovery Program for a third time in July 2019 and was selected for further study in February 2020. We proposed an Io Volcano Observer (IVO) study concept, because the ASRGs enable pointing flexibility and a high data rate from a low-cost mission in Jupiter orbit. [1][5][8], The current hyperactive geology of Io is of great scientific interest in of itself but IVO seeks to understand fundamental processes that have implications far beyond this very unusual moon.
