Ganymede

"Heinlein seems to have a particular fondness for Ganymede: one of the young fellows in Space Cadet was a Ganymedean colonist, the hero of Between Planets was born in a ship that was on its way to Ganymede; Farmer in the Sky is about the settling of Ganymede."

-Alexei Panshin, Heinlein In Dimension (Chicago, 1968), III, 5, p. 58.

(Space Cadet and Farmer in the Sky, but not Between Planets, belong in Heinlein's Juvenile Future History together with Red Planet, The Rolling Stones and Time For The Stars.)

In James Blish's The Seedling Stars, Ganymede is not terraformed but colonized by Adapted Men.

In Poul Anderson's Three Worlds To Conquer, there is a Ganymedean base for communication with Jovians. In Anderson's Flandry series, there is a Ganymedean base for visits to Jupiter. In Anderson's Psychotechnic History, Planetary Engineers survey Ganymede to determine whether it can be terraformed. In Anderson's Twilight World, Epilogue, Ganymede is being terraformed.

Another parallel with Blish is that, in Twilight World, Homo Superior will restore the Terrestrial ecology and, in The Seedling Stars, Adapted Men will recolonize Earth.

A Planetary Engineer says that the Uranian moons are too far away to colonize yet, in Olaf Stapledon's Last And First Men, a later human species colonizes Neptune albeit in a changed Solar System.
