Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

That's my fault, by the way.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

I came up with all that.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

So every letter of the mission name spells out part of the science investigation.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And what really drives us is this origin science, going back to those big questions that I first thought about as an undergraduate here at U of A. Where did we come from?

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And this asteroid, it tells part of that story.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

It's ancient.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

It's four and a half billion years old.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And we believe it's loaded with organic compounds and water molecules.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And we think something like this brought those materials to the very early Earth and is the reason we have oceans and the reason we have life on this planet.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

So the idea is you go back and you understand the chemistry that led to us being here today on this beautiful, wonderful planet that we live on.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And that'll help you understand how common is that process, how complicated was the chemistry, and how likely is that to have happened somewhere else in our solar system

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And we actually think there's a couple locations in our solar system where there might be at least primitive life.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And then, of course, elsewhere in the galaxy and elsewhere in the universe, ultimately getting me back someday to that setting investigation that I was discouraged from pursuing as an undergrad.

Tucson Humanities Festival 2017

We care about how we use telescopes to study asteroids.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

We care about mining asteroids.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

We care about asteroids crashing into the Earth and causing another extinction event like the dinosaurs experienced.

And so when we, I told you that story, the first two times we wrote the proposal, we were the Osiris mission.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And then we actually got to go into a higher budget program called the New Frontiers program.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

And so we wanted to keep the OSIRIS brand name because NASA knew who we were and what OSIRIS was, but we also wanted to indicate we were kind of bigger and stronger and better than OSIRIS.

Tucson Humanities Festival 2017
Exploring The Universe: Science and Humanities United

So we were thinking, okay, what should the mission name be?
