About 10 per cent of this comet is made of organic materials. We don't know exactly what they all are but it is very exciting. |
All the engineers who built it seemed to be happy. It's very strong. |
But the study of these materials will go on for decades. |
Each year we have 30 to 40,000 tons of primitive material from comets and asteroids that lands on Earth, and this is about one particle per square meter per day. So during the course of our seven-year mission, there was more comet dust collected in your backyard than what we're bringing home. |
Every grain that we collected has a story to tell. |
Five minutes before it was supposed to come in, we ran outside. I saw this red thing that, at first, I thought was Mars. Then I noticed it was moving, from our angle it appeared to be climbing. Pretty soon, it had this glowing, reddish tail that lasted maybe half a minute. ... We were all yelling and jumping up and down. |
I'm usually looking down, into a microscope. |
In recent decades, spacecraft have passed fairly close to comets and provided us with excellent data. Stardust, however, marks the first time that we have ever collected samples from a comet and brought them back to Earth for study. |
Inside this thing is our treasure. |
It felt like the whole thing was on the verge of disaster. There was this guy with his finger on a button to blow the vehicle up if it went off range. ... No one said anything for minutes. |
It's a crystalline silicate grain. This is great; we've already got scientific results. |
It's a very exciting mystery story. So stay tuned. |
It's hard to convey to people how tense these situations can be. |
It's hard to describe what it feels like to finally be here. |
Life is fairly easy to create, but I think planets like Earth are going to be rare. |
