Exciting news is buzzing from NASA's Juno spacecraft, which has been on an astonishing journey around Jupiter since 2016. Just recently, it faced a little hiccup but bounced back like a pro!

On April 9, NASA announced that Juno is back in full swing. But what happened before that? Hold onto your seats!

On April 4, Juno unexpectedly slipped into "safe mode" not once, but twice! The first glitch occurred at 5:17 a.m. EDT, right before its 71st close encounter with Jupiter, famously dubbed perijove. Just 45 minutes post-perijove, it hit safe mode again.

Now, before you panic, safe mode isn’t as terrifying as it sounds. It's standard procedure when a spacecraft encounters anomalies. Think of it as a protective shield; Juno temporarily shuts down its instruments to ensure everything's okay before continuing its cosmic adventure.

Interestingly, Juno isn't the only famous spacecraft to experience this. The Hubble Space Telescope and the TESS satellite have both entered safe mode in the past, and similar to them, Juno has faced this scenario previously without any lasting issues.

As for what caused this puzzling glitch, scientists suspect it’s linked to the intense radiation belts surrounding Jupiter. These belts are treacherous, filled with charged particles traveling at mind-blowing speeds—much fiercer than Earth’s Van Allen belts. To protect its sensitive electronics from these high-energy intruders, Juno is equipped with a robust titanium radiation vault.

Be on the lookout for Juno's next close encounter with these radiation belts on May 7. Let’s hope it keeps its cool and continues to send back those breathtaking insights from the giant gas planet!
