They've just been using it for scatterometry and radiometry on the other icy moons, because those measurements can be made at a considerable distance, allowing time to re-orient the spacecraft to point its cameras and spectrometers at the moon during the closest part of the flyby. The SAR and altimetry can only be done at close range (I believe closer than 2000 km) -- meaning that if you use them on a moon, you have to sacrifice your visual imaging and spectral mapping, which simply isn't worthwhile for any moon whose surface you can see unobstructed by haze (especially given the small number of achievable close flybys of other moons).
Enceladus, as Richard suggests, just might be an exception if they make several more close passes -- SAR can penetrate (I believe) about 10 meters under the ice, which means that it might be able to locate near-surface water pockets. But this is a long-shot possibility for the extended mission. |
