"These are the snows of yesteryear," Tyson said of the Oort cloud. "Drifting mountains of ice and rock, the preserved remnants of the birth of the solar system."

AAAAARRRRGGGGHHHHH!!!!!!! We've visited three comets, slammed a 643 pound mass of copper into one, and flown by several more including Halleys. . . NOT ONCE has any ice or water been observed or found. None. Zip! NADA! The closest was the observation of some hydroxyl radicals (OH) released when the Deep Impact probe impacted Comet 9P / Tempel in amounts less than 1/100th the amount expected for H₂O. Yet there was no water at all. In fact, except by orbit, every comet was essentially indistinguishable from every asteroid we've visited, flown by, or probed.

But her is Tyson, nine years later, ignoring all the results of those fly-bys, touch-downs, and the impact and STILL talking about "ice and rock mountains!" That theory has been FALSIFIED! In spades!

I expect current science from this "update," not a rehash of discredited, old theories.

Where are you getting the "no water" idea?

From Wikipedia's Deep Impact article:

A total of 5 million kilograms (11 million pounds) of water[36] and between 10 and 25 million kilograms (22 and 55 million pounds) of dust were lost from the impact.[34]

Reference 36 is to a BBC news item, "Impactor ejects mighty water mass"

But everybody knows that comets are just "dirty snowballs".

Just like there is a "dark side" of the moon.
