features incredible saw seen solar steep system
We saw incredible features -- steep cliffs, overhanging cliffs, spires and many other things we had never seen on other solar system bodies.
actual believe billion blocks building collecting formed information particles solar stored system
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.
formed hot major planets pluto regions solar sun system thrown
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.
comet features incredible oddly saw seen solar steep stunned system
We were stunned when we got to the comet and saw incredible features - steep cliffs, overhanging cliffs, spires and many features which, oddly enough, we had never been seen on other Solar System bodies.
came comet edge formed inner lifetime pluto recently sample solar spent system until
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.
believe best beyond bodies collecting comet formed major mission planets preserved reason samples solar system
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.
atoms attachment blocks bodies building carbon fact forth literally planetary rings solar stardust strong system
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.
atoms blocks bodies building carbon comet coming forth literally planetary solar stardust system
These are literally the building blocks of our planetary system. All of the atoms in our bodies - the carbon atoms, the oxygen, the nitrogen, potassium, calcium and so forth - all of those atoms were in stardust grains like those coming out of the comet now before the solar system formed.
believe billion coming materials
We believe materials coming out of comets now is the same material that went into comets 4.5 billion years ago.
collected either form found high hottest normally red samples siberia solar white
We found the hottest samples in the coldest place. These are mineral grains that normally form under high temperature conditions. They were either red hot or white hot grains. Yet they were collected in the Siberia of the solar system.
collected grain
Every grain that we collected has a story to tell.
bright people quite sure
We weren't quite sure how bright it was going to be and some people didn't think we would see anything.
fantastic quite
We are approaching the end of a quite fantastic voyage.
becomes crew far floating galaxy giant intrigued million names outlive people red silicon spacecraft sun
We have a crew onboard of over a million people -- their names are etched in a little silicon chip. As an astrobiology-type person, I'm intrigued by the thought that those names and that spacecraft will far outlive the Earth. When the Sun becomes a red giant and scorches the Earth, that spacecraft and those names will still be floating around the galaxy somewhere.
