In 2011, tech journalist Jack Dearlove was at university and won a competition to go to the Kennedy Space Center to "live tweet" the last American Space Shuttle. As a self-confessed space nerd, it was one of the most exciting - and emotional - days of his life. But what was it like for the astronauts on board? Here he talks to Doug Hurley, one of the four on board. Now in his fifties, Doug is still planning one last mission into space, with Elon Musk's new generation of space craft. If successful, it will allow American astronauts once again to go into space from American soil.
