On Saturday, Feb. 3, NASA’s Juno spacecraft made a second close flyby of Jupiter’s moon Io. Like the previous flyby on Dec. 30, 2023, this second pass was at a distance of about 930 miles (1,500 kilometers).
Gravity data collected by NASA’s Juno mission indicates Jupiter’s atmospheric winds penetrate the planet in a cylindrical manner, parallel to its spin axis. A paper on the findings was recently published in the journal Nature Astronomy.
Just hours before NASA’s Juno mission completed its 53rd close flyby of Jupiter on July 31, 2023, the spacecraft sped past the planet’s volcanic moon Io and captured this dramatic view of both bodies in the same frame.
On March 1, 2023, NASA’s Juno mission completed its 49th close flyby of Jupiter. As the spacecraft flew low over the giant planet’s cloud tops, its JunoCam instrument captured this look at bands of high-altitude haze forming above cyclones in an area known at Jet N7.
