Europa
From Acw
Europa is a Moon of Jupiter. It was given to the Italians in 2115 by the Germans, before the schism between the former Allies, when Italy became Neutral, and decided to limit its operations to Sol only.

Geology and Geography
Geological Structure and History
Europa's internal structure consists of a central core composed predominately of iron, a viscous molten mantle and an outer crustal layer composed largely of silica. Where it differs from Earth is in the nature of its mantle, which is proportinally thinner than that of Earth's, and in the additional water layer that completely covers the moon's surface. This water layer is stratified into a icy outer crust and a saline aqueous interior.
Europa is tectonically active, with internal convection driven by tidal friction, where excess orbital and rotational energy are dissipated as heat in the crust. All of its crustal surface is composed of what on Earth would be known as oceanic crust, so its geology is largely one-dimensional and the entire surface is covered in cooled basaltic material.
As Europa does not possess any cratonic regions, the complete geological history of the moon is impossible to determine. No rock on Europa is older than 60 Ma, with anything older long destroyed by subduction. All that can determined is that the current geological regime has been in place for at least a 60 million year period.
Geography
The icy exterior of the moon makes Europa one of the smoothest objects in the Sol system. Topographically its surface is virtually devoid of features, with the only relief structures consisting of recently formed impact craters.
Below the outer water layer, the crustal surface of Europa is highly variable with long volcanic mountains chains and trench systems criss-crossing the moon, following divergent and convergent plate boundaries respectively. However, much of Europa's surface consists of vast uneven plains, composed of ropey pillow lavas.
Life on Europa
The first Grossdeutschland scientists to arrive on Europa were ecstatic to find that the moon did possess life, as had been hypothesised for some time, although only in a very primative form. An extensive network of black smokers and other hydrothermal vents are present on the moon's crustal surface and, at these, a primitive chemoautotrophic bacteria was discovered. Why more advanced organisms, like those found at black smoker sites on earth, are not present is still unknown.
