Let's rewind to Europa, 1949...

Yes, Bonestell DID image the outer Solar System. Here in, The Conquest of Space. But how predictive it was of Voyager's findings thirty years later. The moon is now known to be an icy and preeminent destination for manned and unmanned missions alike.

In fact, Ley wrote, "the albedo (reflective power) of Europa is 20% greater than Jupiter itself, indicating that it must be covered frozen gases OR ice!"

Can you find the astronauts?

Can you find Io and Ganymede?

Why is the Great Red Spot missing? It had been discovered by Robert Hooke (who also discovered cells, the building blocks of life through a microscope) in 1664. Oh the restraint of Bonestell to put it on the other side!
