Donald Brownlee Quotations

We've brought back an ancient cosmic treasure from the very edge of the solar system.

Scientifically, that's great, because there's been lots of discussion of whether comets contain minerals or glass.

I'm confident that the particles will be the most primitive stuff we've ever had on Earth.

We're seeing a variety of things that we know absolutely come from a comet.

When they formed, they were either red-hot or white-hot and we found them in the Siberia of the solar system.

We're in excellent shape. We've done almost everything we have to do in the entire mission...only thing left is to come into the Earth.

We're approaching the end of a fantastic voyage. This is the farthest anything from Earth has traveled and come back. Soon we'll be able to examine the building blocks that formed the solar system 4.6 billion years ago.

The most interesting thing about comets is they are libraries with the stored records of our formation.

Comets are like libraries, storing the record of our formation in tiny particles.

We were totally overwhelmed by the ability to actually see this so quickly and so straightforwardly.
