The government will see that human spaceflight is useful - for science and the economy - and inspirational.

During launch, the outside of the rocket is covered in a protective fairing, so we couldn't see outside, but as soon as that was jettisoned, my first view of the earth was over the Pacific Ocean, which was this wonderful deep blue, with clouds just over the top, and sunlight streaming in through the window.

I'd love to go back to space, I don't know any astronaut who doesn't want to.

While we've taken seeds into space, and astronauts on the International Space Station have eaten lettuce they've grown, we haven't produced fruit in space, so we can't pollinate something.
