Quotes by Donald Brownlee
The community is real jazzed about it. People all over the world, using all kinds of fantastic instruments and new techniques, are ready. We've got the best people signed up to do the analyses,
Comets are like libraries, storing the record of our formation in tiny particles.
Inside this thing is our treasure, our sample of the edge of the solar system that truly contains star dust.
In the coldest part of the solar system, we've found samples that have formed at extremely high temperatures. When these minerals formed, they were either red-hot or white-hot grains.
In the coming days we'll be documenting the positions and character of all the tracks, looking at some of them in more detail.
I fully expect that textbooks in the future will have a lot of information about the formation of the solar system from these samples that landed this morning in Utah.
I'm confident that the particles will be the most primitive stuff we've ever had on Earth.
The interesting thing is we are finding these high-temperature minerals in materials from the coldest place in the solar system.
It's really quite an epic thing. I think it tends to get overlooked because it's just a little mission, and there aren't any people on board.
