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.

We believe materials coming out of comets now is the same material that went into comets 4.5 billion years ago.
