I'm surprised that there is no laser altimeter in the Europa spacecraft payload. There's no indication of an altimetry mode in the radar instrument, so the mystery deepens. I was under the impression that determining the exact shape of Europa was important for modeling the tidal heating from Jupiter. It's possible to get some topographic information from stereo imaging, but it's hard to imagine getting the large area coverage with high resolution I think is necessary for detailed shape modeling.

Laser altimetry would be useful only if the measurements are made over the same location at different points in Europa's orbit. -------------------- |
