I think every time we send a spacecraft to an asteroid or comet, we learn more.

I'm a bit delusional, but every time I do a job, I think I'm retired.

Every time I do a movie, I think it's going to be a huge hit.

I think that, a lot of times, people have this idea that the solar system is entirely explored, that we have sent spacecraft to every planet, we've taken beautiful pictures of everything, and that it's kind of done.

It came so soon and so fast. It's just overwhelming. Every time I think about it, I just can't believe it.

Changing the asteroid's velocity changes the time when the asteroid crosses Earth's orbit. After all, just because it crosses Earth's path doesn't mean there is necessarily going to be a collision. It has to cross Earth's path when the Earth is right there.
