Did you know that the ancient Greeks credited Hera with creating the Milky Way from an errant stream of breast milk? True, uh, myth. Not sure why the nigh-omnipotent Queen on the Gods would need a spacesuit; maybe, since she is also the goddess of the air she wanted to bring a little of her native atmosphere with her while she visited her old handiwork.
You can read the actual story in my new graphic novel Hera: The Goddess and Her Glory, coming out July 19th everywhere! Subtle plug!
