StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Fluid moved through that asteroid four and a half billion years ago because the asteroid became active.

When the asteroid created rock in the earliest time period, it created ices, not just water ice, but ammonia, carbon dioxide, carbon monoxide, etc.

And then the asteroid internally began to heat up and you have fluid moving through.

Now, why is that any relevance whatsoever to prebiotic compound?

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Because prebiotic compounds...

may very well have formed in that aqueous or water-rich environment.

The evaporite minerals that we talked about are the late stage product of the fluid that moved through, that formed other minerals first, and they're the very last stage.

Now, if you're an organic chemist

and you want to get organics to come out of a solution, one of the time classic methods of doing that in a laboratory is you salt the solution, and the organics go with the evaporated minerals or the salt when you evaporate the fluid.

StarTalk Radio

We're right.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

I'm sorry.

StarTalk Radio

You're right.

It's a dwarf planet.

StarTalk Radio

I'm sorry.

StarTalk Radio

I'm behind 30 years, right?

StarTalk Radio

We've found a lot in the rock, and we're finding more.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And they also...

StarTalk Radio

Found a lot of organic compounds, because we're talking about organic compounds and the minerals associated with them in the Rugu sample.

StarTalk Radio

The difference is that in Hayabusa 2, which was a Jackson mission to asteroid Rugu that brought back sample, they brought back 5.2 gram.

So they have a lot less.
