Hi All,

 

As par for the course for me; at work and thinking about the night sky.  I find myself curious what time will Cassini crash into Saturn, and then I wonder if it would be viewable as a flash or anything form earth?  Anyone know the answers to these burning questions?

Cassini will enter Saturn's atmosphere at 1153 UT on Friday and 60 seconds later, 940 miles above the cloud-tops, will break up as a meteor. Nothing will be visible from Earth. Farewell!

Too bad apparently we won't see nice closeups of Saturn's rings.

NASA TV will be broadcasting commentary and I suspect loss of signal coverage starting at 7 Friday morning, which I assume is eastern time.

I will be watching NASA Live Feed running from 7 to 8:30 am EDT. Such a fabulous accomplishment: we are all so changed by Cassini. It will be like loosing a good old friend.

Check out the NASA links posted and do a Google search for Cassini - She has been flying through the rings for months - plenty of very excellent, awe-inspiring close-up shots.

Still cool to watch Saturn during those minutes when Cassini is burning up - regardless of whether anything can be seen or not - and those in Australia are well situated apparently. This article is intriguing:

NASA's Cassini probe is about to plunge to its doom — and its fiery death may be visible to telescopes on Earth

Yeah even those professional observatories will still be hard pressed to see anything... But weirder things have happened.

4:45 p.m. PDT 

Cassini has begun transmitting data -- including the final images taken by its imaging cameras -- in advance of its final plunge into Saturn on Sept. 15. The spacecraft is in the process of emptying its onboard solid-state recorder of all science data, prior to reconfiguring for a near-real-time data relay during the final plunge. Unprocessed (or "raw" images) are available here. The communications link with the spacecraft is continuous from now through the end of mission (about 12 hours

Can't help but feel a lot of sadness tonight.  I'm watching NASA's DSN Now feed with the Cassini downlink data feeds coming in...when I wake up in the morning those will never be there again.  RIP little bus-sized buddy.

Yup that little bugger is probably asking a guy at NASA named Dave "Will I dream?"

It's over. Hard to believe. The outpouring of emotional sentiment from so many quarters, contributors in so many varied disciplines enjoying their victorious moment of accomplishment, 30, 20, 10, 5 years of dedicated service to a cause that has changed us all. We are not the same as we once were, not even the same as we were 2 hrs. ago. The intergenerational baton was passed and the wisdom of international collaboration was honored--beautiful moments.

CASSINI and dedicated team, job extremely well done!!bow.gif

Thanks for the reminder. I have it now.  What an excellent tribute to such a phenomenal human endeavor.

I hope it will be available in hardbound.

Cassini's Final moments.  And to think it took 1 hr 23 mins for the signal to reach earth.

Surprisingly they did. That's out of character for them these days... Although, Cassini's story is about Death and Destruction.. So maybe it's not out of character?

With so much eclipse coverage so close in date to this event, I think that had an impact on it. I have talked to a few that have not cared at all about space until the eclipse when they saw Totality. 

RIP Cassini, and thank you!
