I made a very rough prediction that Huygens would be ~800km off-target and be moving faster upon entry than expected - It's all on the Potential Threat to Huygens' thread. The preliminary data (Elias posted references to) has visual graphs that indicate Huygens was 1100 km off-target, and moving more than 30m/s faster-than-expected and continued to accelerate for almost two minutes after first detection!

The rest of the Doppler data is completely consistent with a much faster than expected descent and deceleration.

So I don't see anything inconsistent with my hypothesis EXCEPT for the landing time. In any case, the data are all preliminary, and we are not likely to have hard numbers until June.

I don't have any problem waiting for the data. In the extended Cassini mission, they hope to do a lot of Doppler ranging and gravitational/mass measurements. If I am right, every time they collect ranging data during a close pass, Cassini will record a high (positive) gravity anomally that does not correlate with surface features, only with time of closest measured approach.

I can't think of anything more exciting than making a prediction based upon a completely new and original concept of science, and having a mission actively testing and constraining that hypothesis. Even if it turns out to be wrong!
