[extropy-chat] Doh! ppler

<The probe will radio data back to Cassini up to a maximum of 30 minutes 
after touchdown. By then either its batteries will have failed or Cassini 
will have gone over Titan's horizon.

In 2000, mission officials discovered a problem that would have prevented 
Cassini from receiving most of that data. The design had not accounted for 
the Doppler effect which will change the frequency of the transmissions as 
Huygens falls through the atmosphere.>

Good grief. I guess you don't have to be a rocket scientist... :)
