Our mission is called Stardust, in part because we believe some of the particles in the comet will, in fact, be older than the sun.

About 10 per cent of this comet is made of organic materials. We don't know exactly what they all are but it is very exciting.

You're seeing the very first, absolutely identified comet particle that has ever been seen.

We are confident [the comet] was made out of the initial building blocks of our solar system.

We are collecting the actual building blocks the solar system was formed from 4.5 billion years ago. We believe that the particles have a lot of information stored in them.

We visited a comet, grabbed a piece of it, and landed here this morning. It was a real thrill.
