Galileo NIMS Europa Hyperspectral Images
Europa surface composition from near-infrared spectroscopy
The Near-Infrared Mapping Spectrometer (NIMS) aboard the Galileo spacecraft acquired hyperspectral images of Europa’s surface, revealing the distribution of water ice and hydrated minerals across this ocean world.

Scientific Background
Europa’s surface is dominated by water ice, but NIMS observations revealed additional spectral features indicating the presence of hydrated minerals and other non-ice materials. These hydrated compounds may provide clues about the composition of Europa’s subsurface ocean and its potential for habitability.
