The view from space is really very special. From the window, you can look back at the Earth and see the stars around you. I just hope that more people from Britain get the chance to experience it.
I get standing ovations at meetings when I say Britain should be involved in human spaceflight. Unfortunately, that goal has been blocked by a handful of people in high office.
People are fascinated by space flight. It makes them interested in science, gets them asking questions and motivates them.
It's very exciting that people could actually live on another planet.
Is a one-way trip to Mars ever really seriously going to happen? Surely that's morally reprehensible. However old people are, however much they say they want to go on a one-way mission, people should be thinking about the possibility of returning.
