"NASA's Juno Captures Close-Up of Jupiter's Volcanic Moon Io in Daring Flyby"

NASA's Juno spacecraft captured the most detailed images of Jupiter's volcanic moon Io in 22 years, flying just 930 miles above its surface on December 30, 2023. These images reveal the intense volcanic activity on Io, which is driven by the gravitational pull of Jupiter and its other moons. Juno's mission has included flybys of Jupiter's Galilean moons, and while future missions like JUICE and Europa Clipper will explore other moons, there are currently no missions planned for Io following the Io Volcano Observer's (IVO) proposal loss in 2021. Juno will continue to orbit Jupiter and is scheduled for another close flyby of Io in February 2024.
