Re: I hope..
@Unicornpiss - there's some argument that people like Tim Peake, Chris Hadfield, Peggy Whitson, Luca Parmitano, Helen Sharman, Michael Foale and Sunita Williams would all class as such heroes. Or at least deserve to, as probably do anyone with the balls to sit on a large firework built by the lowest bidder and pork-barrel scraper.
Maybe not the pioneers that the Mercury, Gemini and Apollo guys were, but still risk takers (such as Parmitano almost drowning in space) and great ambassadors for space and science in general to the public.
And as the shuttle sadly showed twice, even with "mature" technology, they could still kill if things went wrong.
