Too many people view on [space exploration] as a luxury rather than as a fundamental driver to stimulate interest in science to everyone in the educational pipeline. It's vital to our prosperity and security.

I've always been interested in pop culture. Some of my colleagues think of pop culture as beneath them, or there's the ivory tower and then there's everybody else, and I never could buy into that wall that's been put up by so many people over the decades and even the centuries.

The history of exploration across nations and across time is not one where nations said, 'Let's explore because it's fun.' It was, 'Let's explore so that we can claim lands for our country, so that we can open up new trade routes; let's explore so we can become more powerful.'

Somehow it's O.K. for people to chuckle about not being good at math. Yet if I said, 'I never learned to read,' they'd say I was an illiterate dolt.

Americans live in a free country, which allows you to believe what you want. Because you think that something is true does not require that it is objectively true.
