The Eye of Japetus Composite

"When Bowman had first observed Japetus, that curious elliptical patch, of brilliance had been partly in shadow, illuminated only by the light of Saturn. Now, as the Moon moved slowly along its seventy-nine-day orbit, it was emerging into the full light of day.
As he watched it grow, and Discovery rose more and more sluggishly toward her inevitable appointment, Bowman became aware of a disturbing obsession. He never mentioned it in his conversations – or, rather, his running commentaries – with Mission Control, because it might have seemed that he was already suffering from delusions."- Arthur C Clarke from the novel 2001 a space odyssey-
