At this point in time, we're absolutely thrilled. It's totally remarkable to have a fully successful mission. Of all the things that could go wrong either in space or even scientifically, none of the bad things happened and everything really exceeded our wildest expectations.

Comets are like libraries, storing the record of our formation in tiny particles.
|
Comets do blow up unexpectedly,

If it was formed in our solar system, then it had to be transported from the hottest regions to the coolest.

In the coldest part of the solar system, we have found samples that formed at extremely high temperatures?so the hottest samples [are in] the coldest place.
|
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.

Inside this thing is our treasure, our sample of the edge of the solar system that truly contains star dust.
|
It exceeded all of our grandest expectations. We should have more than 1 million particles larger than 1 micron in diameter.
|
It exceeds all expectations. It's a huge success.
|
It exceeds all expectations. It's a huge success. We can see lots of impacts. There are big ones, there are small ones.
