StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So for us, we were able to do work for organics on individual stones from Bennu and also homogenized powder of more than six grams that we homogenized up to really understand the chemistry well.

And indeed, they have found that the main headlines is, you know, 14 of the 20 amino acids that are needed for life.

StarTalk Radio

But really, it's probably 15 because a paper by Mahara et al.

StarTalk Radio

that came out in November found the 15th one.

And we have to reproduce it.

But that was right near Thanksgiving.

And that 15th one was tryptophan, which is the same stuff.

You're getting turkeys that make you sleepy, right?

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Yeah, so the report, and the report,

talked about basically the byproducts of breaking down fatty acids, if my memory serves me right, and alkenes and some single sort of chain organic molecules.

I think that's one of the other data points that they're using to, the scientists who wrote that paper, are using to argue that there's additional evidence of potential biological processes that were around at that time 80 million years ago, which is the Cretaceous period here on Earth.

So here on Earth, dinosaurs would have been walking around at that same time period.

And that's a lot younger than the 8400.

Allen Hills, 84, oh, and that rock is, because that's about 4.1 or 2 billion years old, that rock.

So the likelihood, at least more confidence can be given that that's a nicer way to construct an app office.

But again, we still have so much to learn about the formation of organic compounds in the relationship to geology and the rocks.

And to...

You know, to go off too much in one direction or the other, I think the middle path is required here.

Raigu, whose mission was that one?

StarTalk Radio

So JAXA, the Japanese Space Agency, has had two sample return missions.
