Welcome to Star Talk.

You're a place in the universe where science and pop culture collide.

Star Talk begins right now.

This is Star Talk by your host, Neil deGrasse Tyson, your personal astrophysicist.

And this is going to be a cosmic queries edition.

And I've got a guest co-host. She's an old-timer with us, Marsha Beltsky-Marsha. Welcome back.

Thank you so much. It is always so fun to be here. I learned so much.

This is my only postgraduate education that I have.

Oh, is that right? Okay.

It's an honor to be back.

Great. So since you do agree to keep coming back, it can't be all that bad for you.

Yes.

So today, we're going to talk about asteroids.

And our expert guest is Marina Brosgevich.

Thank you for joining Star Talk.

You work at the Jet Propulsion Labs in Pasadena, California.

And presumably, they don't only do Jet Propulsion.

So what is the Jet Propulsion Laboratory? Tell everybody.

We are specialized in robotic explorations of the Solar System.

So we run missions like, you know, there was Cassini on Saturn and we run Mars Rovers.

But we also do a lot of science.

So a lot of the science work that we do here are asteroids.
