We fly to 106 kilometers. We've always had as our mission that we always wanted to fly above the Karman line because we didn't want there to be any asterisks next to your name about whether you're an astronaut or not.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

With the amount of fixed expense that goes into developing something like the BE-4 engine, you want it to be used as much as possible.

I read 'The High Frontier' in high school. I read it multiple times, and I was already primed. As soon as I read it, it made sense to me. It seemed very clear that planetary surfaces were not the right place for an expanding civilization inside our solar system.

We have the resources to build room for a trillion humans in this solar system, and when we have a trillion humans, we'll have a thousand Einsteins and a thousand Mozarts. It will be a way more interesting place to live.

We need to know what the resources of the moon are. We have great evidence now because of different kinds of radar andspectroscopic analysis that people have been able to do. But we really do need to go visit there, and we can do that with a robot craft without any problem.
