The curious factor here is that you could have a dozen-odd ones hit the Earth, and dump enough water to affect weather patterns (oh yeah, like climate change), and raise water levels around the planet by a couple of inches.
By analyzing the particles in a secondary ion mass spectrometer, Bose and Jin identified that Itokawa contained water and hydrogen isotopes in levels that are indistinguishable from rocks found on Earth.Answers what a lot of people wonder about; namely, how can they tell Earth's water came from such and such a place? Well... water has its "fingerprints." Like many substances, and us, too.
Yeah, well, Was it purified, or Perrier?
I hope they don’t expect a tip.
Thanks LibWhacker! The Big Splash keyword, chrono sorted:

Hayabusa, of love, say what. Thanks LibWhacker!
My Culligan man is extra-celestial? He looks more Neanderthal.
Perhaps the raising of the water level would be the last of a person’s worries after comet/asteroid strikes of that magnitude?
Iceteroids!
...keep ‘em comin’
...and monkeys...

Well, I ain’t no scientist, but I used to be a science teacher.
What they don’t address is QUANTITY.
So how does a few molecules of water found in a grain of dust on a very dry asteroid translate into the almost immeasurable quantity of water found on our planet?
They leave out this tiny fact.
What is missing with so many scientists? Common sense.
The chemistry (H2O) of any water anywhere should match that of water on earth.
And these morons get paid to produce such stupidity.
No, as explained in the article, they’re looking at deuterium. The relative amount of deuterium in water will be different from source to source.
Well, when is the OTHER half coming???
Wow, thanks for the incisive refutation. You ought to publish it.
The quantity of observed water on Earth came from many impacts.z
Some math guy could probably destroy this unusual theory. Since about 70% of the Earth’s surface is water, some of it miles deep, the sheer volume of water we have would mean that an even greater volume of asteroids would have had to pummel Earth, leaving giant craters and piles if rock debris that should be easily visible.
Seems to me that the Earth should look like a piece of Swiss cheese floating in space.
