re: Cassini plunges into Saturn on Sept 15th

Good NASA page detailing the timeline of Cassini's Grand Finale: LINK
Because Saturn is so far from Earth, Cassini will have been gone for about 83 minutes by the time its final signal reaches the Deep Space Network's Canberra station in Australia on Sept. 15, 2017.
The current predicted time for loss of signal on Earth is 4:55 a.m. PDT (7:55 a.m. EDT) on Sept. 15, 2017. This time may change as Saturn's atmosphere slows Cassini during each of the final orbits.
Times in left column are spacecraft event time, i.e., when the events happen at Saturn. "ERT" (in right column for some entries) refers to Earth received time, which is the time when the spacecraft's signal relaying the event arrives on Earth. After events happen at Saturn, it takes 83 minutes for Cassini's radio signal to reach Earth.

Today is Cassini's last full day in one piece.

I watched a NOVA documentary on Cassini last night... the pictures were as incredible as the science behind what and how they're doing it
Cool stuff

Imagine if everything scientist knew about Saturn was wrong and they had some primitive beings living tribal there to witness this satellite fall into atmosphere then begin an entire religion around it. All the while we would never know bc the images would blank before seeing any of it.

This picture taken by Cassini is the background of my laptop:
It is the probe whose images have impressed me the most. She will be missed.

Awesome picture and definitely better than having pictures of Uranus as your laptop wallpaper.

Fun fact: we still don't know how long a day on Saturn is.

If I remember correct, Cassini was the source of controversy in 1997 because of its cost and nuclear reactor.
I'd say the payoff was worth it

They were so jealous that Clemson stole everything from them that they had to go somewhere with a lake to get someone to recognize them as champs.

me too, and space is so fricking awesome... to think how far our human intelligence has come in a very short period of time is amazing, but to consider how far away we are from fully understanding it all is really mindblowing....
