Business Insider:

Just after 6:32 a.m. EDT on Friday, a bus-size object will scream over the cloud tops, burst into millions of pieces, and glow like a meteor.

But this meteor isn’t a rock: It’s NASA’s nuclear-powered Cassini spacecraft plunging to its doom.

However, NASA TV is broadcasting live online video of the final stages of Cassini’s “Grand Finale,” the moment its last stream of data comes in, and — by extension — confirmation that it’s died.

An amazing mission and a fitting ending.
