BuckeyeBill73 said:Speed of light = 186,000 miles/second
* 3600 seconds/hour = 669,600,000 miles/hour
So that should take out 1.3 hours (78 minutes) to go about 870 million miles (The 1.4 billion figure was in kilometers).
I don't understand why it takes 5 hours one way.
edit - I wasn't trying to say something different from Hubbard. I was reasearching and calculating while he posted, and didn't see his until after I posted.
Distances and Data Rates
When Cassini is in orbit around Saturn, its distance from Earth will vary from 8.6 to 10.6 AU (1.3 to 1.6 ×10<sup>9</sup> km). Radio signals will take from 68 to 84 minutes to travel between the spacecraft and the ground station.
Depending on the mission phase, the data transmission rate will vary between 5 bits per second and 249 kilobits per second.

The way they presented on their site is that its a seperate picture, this time done in color. Maybe I just read it wrong.Hubbard said:That is the touched up photo. The orginal was black and white and they added color to try and get the "real color" or as best as they could tell.
