Don Brownlee Planets Quotations

Life is fairly easy to create, but I think planets like Earth are going to be rare.

There are two major possibilities. One that they formed in the innermost, hotter-most regions of our solar system when the sun and planets were forming, and they were thrown out -- all the way out to the Pluto region of the solar system. The other possibility is they were formed around other stars, in hot regions around other stars.

The fundamental reason for this mission is that we are collecting what we believe are the best preserved samples of the formation of our solar system and they are preserved because they formed these comet bodies beyond the major planets out beyond Neptune.

This is a history project. We are going to the edge of the solar system, collecting the original building blocks of the planets and bringing them back to our labs.
