Measuring Ganymede’s Librations with Laser Altimetry [PDF]
Geosciences, 2019 Jupiter’s moon Ganymede might be in possession of a subsurface ocean located between two ice layers. However, from Galileo data it is not possible to unambiguously infer the thickness and densities of the individual layers.
