We're collecting things that are very ancient and even older than our solar system. We are literally reaching for the stars.

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 did this mission to collect the most primitive materials we could in the solar system. We went to a comet that formed at the edge of the solar system, far from the sun under very cold conditions. We're confident that it was made out of the initial building blocks of our solar system.

These are literally the building blocks of our planetary system.

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

This comet formed at very edge of the solar system ... out by pluto ... and spent all its lifetime out there until recently it came into the inner part of the solar system, where we could sample it.
