NASA’s Juno spacecraft will fly past Jupiter’s volcanic moon Io on Tuesday, May 16, and then the gas giant itself soon after. The flyby of the Jovian moon will be the closest to date, at an altitude of about 22,060 miles (35,500 kilometers). Now in the third year of its extended mission to investigate the interior of Jupiter, the solar-powered spacecraft will also explore the ring system where some of the gas giant’s inner moons reside.
On April 8, 2023 NASA’s Juno mission completed its 50th close pass by Jupiter since the spacecraft arrived at the giant planet in 2016. In celebration of 50 orbits, this graphic contains 50 images that provide just a small sampling of the data Juno has returned so far, including images from several different instruments, and spectacular views of Earth, Jupiter, and Jupiter’s large moons Ganymede, Europa, and Io.
NASA’s Juno mission is scheduled to obtain images of the Jovian moon Io on Dec. 15 as part of its continuing exploration of Jupiter’s inner moons. Now in the second year of its extended mission to investigate the interior of Jupiter, the solar-powered spacecraft performed a close flyby of Ganymede in 2021 and of Europa earlier this year.
On Nov. 29, 2021, NASA’s Juno mission completed its 38th close flyby of Jupiter. As the spacecraft sped low over the giant planet’s cloud tops, its JunoCam instrument captured this look at two of Jupiter’s largest moons.
On September 29, 2022, NASA’s Juno spacecraft made a close flyby of Jupiter’s icy moon Europa, at a distance of approximately 218 miles (350 kilometers). With a relative velocity of about 14.7 miles per second (23.6 kilometers per second), the Juno spacecraft only had a few minutes to collect data and images during its close flyby of Europa.
