Secrets of Asteroid Bennu with Harold Connolly Jr.

And going back to your analogy of the dog pee, many of these, in fact, they get contaminated, the meteorites, as they fall to Earth very, very quickly.

So within a day or two, you've already...

and you're interacting with the atmosphere, little microbes start to eat them.

I mean, imagine you're sitting around for four and a half billion years, as Neil said, and you've got nothing to do, nobody to bother you, really, except occasional collision and the sun hit you.

So the other idea was to bring back a sample of pristine material, keep it in a nitrogen environment and analyze it.

And that turns out to be, as we'll see, absolutely critical to what we have been finding in both asteroid Rugu sample and, of course, asteroid Bennu
