Io is named for one of the many lovers of Zeus in classical Greek mythology, and the moon has held a unique place in the development of modern science. Not only was it discovered by Galileo in 1610 and helped inspire the heliocentric model of the solar system, it was also used by the Danish astronomer Ole Rømer in 1676 to make the first measurement of the speed of light.
Covered in over 400 active volcanoes, some of which spew sulfur over 500 kilometers into the sky, Io is painted in brilliant shades of yellow and red from the deposits of sulfur and other chemicals on its surface. Colonizing this moon will be a challenge, but one thing is certain: your colonists will never lack for dramatic vistas.
About[]
Io is a yellow moon of Jupiter filled with volcanoes. It is slightly larger than Earth's moon, and the closest Galilean moon to Jupiter. It is part of the Moons of Jupiter set, but can also be bought separately.
Strategy[]
This moon is still small, even if it's slightly larger than our own moon. Think carefully before placing a city and/or an outpost, because they will not be able to place many (like the moon). Be careful for placing cities, because might accidentally put it on a Volcano and then it will suddenly explode and break the city down.
Unlike other moons and dwarf planets in the solar system, Io doesn't have any ocean beneath its surface. Because of that, you can terraform as you normally would (raising temperature, pressure, oxygen, water, plant life, etc.).
Trivia[]
Io is the most geologically active place in the solar system.
Io was named after the mythological character Io, a priestess of Hera who became one of Zeus's lovers.
Io might have a subsurface magma ocean beneath its surface.
