In RobinsonвЂ™s The Memory of Whiteness (1985), the protagonists visit Europa, which hosts large human colonies who live around pools of melted ice. The former novel is partly set on Callisto, where a massive city called Valhalla is built around the concentric rings of the moonвЂ™s giant crater (also mentioned in 2312). Kim Stanley RobinsonвЂ™s novels GalileoвЂ™s Dream (2009) and 2312 (2012) feature colonies on Io, where settlements are adapted to deal with the volcanically active, hostile surface. Meanwhile, a race of genetically-altered humans (called the вЂњDenizensвЂќ) are created to live in the subsurface ocean, close to the core-mantle boundary where hydrothermal vents keep the water warm and the native life forms live. In Bruce SterlingвЂ™s Schismatrix (1985), Europa is inhabited by a faction of genetically-engineered posthumans that are vying for control of the Solar System.ДЄlastair ReynoldsвЂ™s short story вЂњ A Spy in EuropaвЂќ depicts colonies built on the underside of EuropaвЂ™s icy surface. DickвЂ™s short-story The Mold of Yancy (1955), Callisto is home to a colony where the people conform to the dictates of Yancy, a public commentator who speaks to them via public broadcasts. In the short stories вЂњ Not Final!вЂќ (1941) and вЂњ Victory вЂUnintentional'вЂќ (1942), a conflict arises between humans living on Ganymede and the inhabitants of Jupiter. Isaac Asimov also used the moons of Jupiter in his stories. In 2061: Odyssey Three, Clarke also mentions how LuciferвЂ™s warmth has caused GanymedeвЂ™s surface to partially sublimate, creating a large equatorial lake. The warmth of this dwarf star (Lucifer) causes the surface ice on Europa to melt, and the life forms that are evolving underneath are able to emerge. In 2010: Odyssey Two(1982) an ancient race of advanced aliens are turning the moon into a habitable body by converting Jupiter into a second sun.

ClarkeвЂ™s Space Odyssey series, the moon of Europa plays a central role. In this story, a party of terraformers visits a settlement on Ganymede called X, which was established two centuries earlier by a group of American religious fanatics. In 1954, Poul Anderson published a novella titled The Snows of Ganymede(1954).

Many of his HeinleinвЂ™s other novels include passing mentions of a colony on Ganymede, including The Rolling Stones (1952), Double Star (1956), I Will Fear No Evil (1970), and the posthumously-written Variable Star (2006). In the course of the story, it is mentioned that there are also efforts to introduce an atmosphere on Callisto. The moon is in the process of being terraformed in the story, and farmers are being recruited to help turn it into an agricultural colony.Д¬over of Arthur C. HeinleinвЂ™s novel Farmer in the Sky (1953) centers on a teenage boy and his family moving to Ganymede. The concept of a colonized Jovian system is featured in many science fiction publications. And because of the presence of water ice, interior oceans, minerals, and organic molecules, it has been speculated that humanity might establish colonies on one or more of these worlds someday. And with the birth of space exploration, what weвЂ™ve come to know about these satellites has fascinated and inspired us.ДЇor example, ever since the Pioneer and Voyager probes passed through the system decades ago, scientists have suspected that moons like Europa might be our best bet for finding life in our Solar System beyond Earth. As time passed, these moons вЂ“ Io, Europa, Ganymede, and Callisto вЂ“ would collectively come to be referred to as the Galilean Moons, in honor of their discoverer. In 1610, Galileo Galilei became the first astronomer to discover the large moons of Jupiter, using a telescope of his own design.
