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

These are literally the building blocks of our planetary system.

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

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.

These are literally the building blocks of our planetary system. Personally, I feel a strong attachment to this thing and we should all feel a strong attachment to it because the fact is all the atoms in our bodies -- the carbon atoms and the oxygen, nitrogen, potassium and calcium and so forth -- all those atoms were in stardust rings ... before the solar system formed.
