Oh, for Jupiter's Sake!

Jupiter is the Roman equivalent of the Greek god Zeus, the King of the Gods. If you look very far into Greek mythology, you’ll see that it has Zeus’ DNA all over it – literally. Greek myth is largely the story of how Zeus slept with anyone and everyone he took a fancy to, much to the chagrin of his wife, Hera.
 

(It’s interesting to note that Zeus named the offspring of one of these illicit unions Heracles – “Glory of Hera” – in order to appease his wife. It didn’t work.)
 

When Galileo looked at Jupiter through a telescope in 1610, he discovered four large moons. He originally named them after members of the Medici family (remember those guys?), who were his benefactors. That didn’t stick, for much the same reason you could never name a moon or a planet after Joe Biden or Donald Trump today. Eventually, the moons were given the names Io, Ganymede, Europa, and Callisto – all lovers or companions of Zeus.
 

In 2011, NASA launched a spacecraft to explore and study the Jovian (‘Jove’ = Jupiter) system and take pictures, send back data, etc. on Jupiter and its moons. They named the spacecraft Juno. 

Who is Juno? She is the Roman equivalent of Hera – Jupiter’s wife.
 

So when NASA wanted to check of on Jupiter and his harem, who did they send? His wife.
 

Let it never be said that scientists lack a sense of humor.
