Jupiter and the Jovian Moons

Humans began settling these moons in 2080.. In 2160, before the formation of the UNSC, the Frieden, a resurgent fascist movement springing from anti-Koslovic sentiment in the Jovian Moons was formed to achieve peace by destroying the "oppressors on Terra Firma" and it attacked the UN Colonial Advisers on the moon, sparking the Jovian Moons Campaign, the Rain Forest Wars, a series of clashes of Mars, and the Interplanetary War. The Frieden and the Koslovics were defeated, and the moons returned to the control of the UNSC. This conflict was called the Jovian Moons Campaign. During the Human-Covenant War Regrets fleet was detected near Io.

The Galilean Moons

• Europa
  • The smallest, yet only fully terraformed Jovian moon. It features a frosty atmosphere. Although scientists had theorized that it might already contain oceans with amino acids and the building blocks of life, the first colonists found that this was not the case. Colonization occurred without the discovery of any new life forms.
  • The Spartan-II Supersoldiers had a mission on Europa some time before 2552.
  • Europa was left unscathed when the Covenant attacked the Sol System, as it had little militant value to the UNSC.

• Io
  • The third largest Jovian moon. This is where the Frieden first attacked the United Nations.
  • The fleet of the High Prophet of Regret passed near Io where they were detected by Io Station just minutes prior and before the Battle of Earth, allowing UNSC forces to muster a timely response.
  • Despite being massively volcanic and atmospherically volatile, Io supports a large colony of Humans.

• Ganymede
  • The largest Jovian Moon, bigger than both Luna and Mercury.
  • The EVA Armor was developed here.
  • It has been partially terraformed, though supposedly retains a harsh climate. Ganymede is well populated.

• Callisto
  • Callisto is the second largest Jovian Moon.
  • In 2170 it was the site of the signing of the Callisto Treaty which officially ended the Interplanetary War.
  • With little civilian population to speak of, Callisto's purpose is primarily militaristic in nature; the moon's several bases are capable of launching their units and ships within an hour's notice.
  • Herzog claimed to have to deal with paperwork regarding surveillance here.

Trivia

• Jove was another Latin name for the god Jupiter.
