NASA is kicking off the first of several flights in a mission to study the most volcanic place in the solar system: Jupiter's moon Io. NASA's Juno spacecraft, which has been orbiting Jupiter since 2016, will maneuver nine flybys of Io to observe a network of volcanoes and study Jupiter’s magnetosphere, the first close encounters in over two decades. The extended mission, which began last year and is expected to last through the end of 2025, will allow scientists to learn more about how its eruptions interact with Jupiter. Jupiter's powerful gravity and smaller pulls from two moons that orbit farther from Jupiter — Europa and Ganymede — contribute to Io's incredible volcanic activity. #space #jupiter #nasa
