I did a detailed signal analysis of the Deep Impact satellite telemetry data file and posted it to my baudline blog. This file has a curved drifting random walk, modulation, self similarity, and a "surprising discovery that gets even stranger."

The data set's meta.txt file is missing. Does anyone know the base frequency?
The Deep Impact satellite has been renamed EPOXI and is in the news again with some great pictures of Comet Hartley 2:

What a strange looking comet.
Yes, I'd never expect a comet to look like a dog bone or drumstick.
It still amazes me how far science and engineering has come to be able to track down a comet and take relatively close fly by shots.
