Ices on Io — Composition and Texture

  • Douglas B. Nash

Part of the Astrophysics and Space Science Library book series (ASSL, volume 227)


Io is the innermost (nearest to Jupiter) of the four Galilean satellites. We know from their infrared radiometric and spectral signatures that the outer three satellites, Europa, Ganymede, and Callisto, have cold surfaces (~ 120 K or less) containing abundant H2O ice, with Europa’s surface being nearly pure water ice and that of the others showing water ice with dark, presumably non-ice (perhaps rocky) components [Clark et al., 1986].
