I had been lucky that my physiology is well suited to space training.

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.

I still dream about being on the space station with the feeling of being weightless. The weightlessness is the most amazing, relaxing and natural feeling.

I hope there will be continued U.K. investment in human spaceflight to enable Britain to benefit from space travel in the longer term and that many more Britons - women and men - will travel into space.

When the history books are written in a thousand years, when space travel would have become routine, the moment that humans first left Earth will be of huge importance. Star City is a central part of this story and it deserves more recognition.

You don't go into space just for the science. Economically, it is not worth it. I think the reason we should be in space is for the exploration; it's the human endeavour.
