The next day, on June 25th, Juno officially crossed over from the Sun’s magnetic field into Jupiter’s domain. This is basically what I imagine flying into Hell sounds like:

These recordings are but an early taste of what’s to come for the most daredevil planetary science mission ever built. On July 4th, Juno will fire its main engine, slow down from a rip-roaring 165,000 miles per hour to a slightly more modest velocity, and enter orbit around Jupiter. A few months later, it’ll be skimming the gas giant’s polar cloud tops and snapping photos of the largest geomagnetic storms in the solar system at an altitude as low as 3,100 miles, all while getting walloped by the gas giant’s powerful radiation belts.


We’ll be keeping a close eye on the spacecraft’s progress over the days to come, so stay tuned.
