I always knew I'd go to space.

Once I got into space, I was feeling very comfortable in the universe. I felt like I had a right to be anywhere in this universe, that I belonged here as much as any speck of stardust, any comet, any planet.

Some of the most fun people I know are scientists.

We look at science as something very elite, which only a few people can learn. That's just not true. You just have to start early and give kids a foundation. Kids live up, or down, to expectations.

When I'm asked about the relevance to Black people of what I do, I take that as an affront. It presupposes that Black people have never been involved in exploring the heavens, but this is not so. Ancient African empires - Mali, Songhai, Egypt - had scientists, astronomers. The fact is that space and its resources belong to all of us, not to any one group.

Don't let anyone rob you of your imagination, your creativity, or your curiosity. It's your place in the world; it's your life. Go on and do all you can with it, and make it the life you want to live.

My parents were comfortable with me exploring areas that they were not proficient in. Some parents just aren't comfortable with that.
