Nasa TV will be starting coverage in about 3 mins - but I'm watching multiple TV channels to see if any carry coverage - and will post any news thru the day as it happens

QUOTE (DavidVicari @ Jan 14 2005, 11:04 AM) QUOTE (volcanopele @ Jan 14 2005, 05:55 PM) As far as I know, they are not the same data. Maybe you are confusing this with the fact that Huygens will be retransmitting its data several times? No... Huygens will not be re-transmitting its data several times. It sent all its data out in almost real time on two separate redundant channels. One channel was supposed to be delayed by something like 6 seconds so that a temporary comm. loss would not lose data. Cassini will send its recorded data to earth multiple times and from multiple different memory locations. Sorry, I meant Cassini will be retransmitting Huygens data several times for redundancy. Even though Channel A "may" be lost, DISR will still have plenty of nice looking panoramas from the data on Channel B. The Doppler Wind experiment data can be reproduced from the carrier signal on earth and from other Cassini instruments. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
