NASA Mission To Explore Jupiter's Volcanic Moon lo Volcano Observer.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
NASA Mission To Explore Jupiter's Volcanic Moon lo Volcano Observer.
Nasa/Jpl/Dlr nasa/Jpl/DLR.
GALILEAN SATELLITES:-
The four largest moons of Jupiter-lo, Europa, Ganymede, and Callisto.
Recently NASA has started focusing on these Galilean satellites and plans to send probes to explore them.
THE LATEST PROPOSED MISSION BY NASA:-
lo Volcano Observer (IVO) is a proposed low-cost,
outer-planet mission to explore Jupiter's moon lo to understand tidal heating as a fundamental planetary process.

WHY IT WILL BE HISTORIC:-
IVO would be the first mission dedicated to lo.
The a scale of volcanism we've never directly witnessed on Earth-and don't want to, either- but we can directly observe it on lo
lo is also suspected to have a magma ocean hidden beneath its surface.
WHY IO'S KNOWLEDGE IS IMPORTANT:-
That's crucial because the cores of Mercury, Venus, Earth, Mars and the Moon are thought to have formed from cooled and solidified magma oceans. So studying lo could therefore offer a shortcut to peering back in time at how the Solar System formed. It could also teach planetary scientists more about ancient volcanic and tectonic processes on Earth and other planets.
WHY IS IO SO VOLCANIC?:-
lo is in a constant gravitational tug-of-war with Jupiter and the other big moons, so much so that it changes shape during its 42-hour orbit. It's thought that the constant stretching and squishing causes frictional "tidal heating" so great that an ocean of magma is created under the surface.
WHAT IS IVO?:-
IVO would be the first mission dedicated to exploring lo. It's so far only a potential NASA mission, which could launch in late 2028 or 2029 and reach lo 3.5 years later.
It's tag-line is "follow the heat" because lo is just so intensely volcanic.
WHICH OTHER MISSIONS IS IVO UP AGAINST?:-
• Trident: will explore Triton, a unique and highly active icy moon of Neptune.
• VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy): will map Venus' surface to determine the planet's geologic history.
• DAVINCI + (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging Plus): will analyze Venus' atmosphere to understand how it formed and evolved and determine whether Venus ever had an ocean.
WHAT WILL IVO DO?:-
IVO's tour of lo has been designed to accomplish various geophysical objectives plus get lots of great data on its Vulcan Ology.
Once at lo, IVO would perform 10 close flybys.
WHAT IS LOKI PATERA?:-
It's lo's largest volcanic depression, which contains a lake of lava. Loki Patera is the most energetic hotspot on lo a long term hotspot.
