Or corundum?

I have some memory.

Okay, all right.

So let's pivot to other places where these search for ingredients of life have been in the news, such as Mars, right?

We're not quite there yet with Europa.

We've got a nice Clipper mission en route.

We have a whole episode of StarTalk where we toured the Jet Propulsion Labs and spoke to the folks.

It was right around the launch time of the Europa Clipper mission to look for life under the – with ice-penetrating radar to look under the ice, that icy moon with its ocean of liquid water.

But if we go to Mars where there's no water today but such ample evidence that there was once –

running water.

Do you compare notes with your fellow Mars geologists or Marsologists, whatever the word is you might call them, to see?

Because I remember there's a recent news where there were some inclusions in some kind of clay or something that

people felt pretty sure is a record of some kind of microbial life thriving in a distant past.

And there are inclusions that only a geologist would recognize as being something interesting, and then you pair that up with the biologists, and all the astronomer can do is just watch you guys have a conversation about it.

And just to be clear for everyone in this modern era, it means a research paper with many collaborators that has been submitted for peer review, has been revised according to whatever the peer review might have recommended.

Then it shows up in the journal, online or otherwise.

And that then gets disseminated around the world for others to comment on, to stand on the shoulders of what was there.

That's what's going on here.
