Comments: Euterpe is the smaller of the inner middle moons, and is in many respects like Jupiter's Europa, it has a thick ice crust over silicate core. Magnetometer readings, and later probe analysis confirms a deep subsurface ocean, though is not life bearing (federation seeding programs have been discussed though no action taken as yet). The moon also has a very faint atmosphere, mostly of monatomic oxygen caused by bombardment of the icy surface.
