Alternate title: Have Shuttles, will Travel:

The co-founder of a rocket launch firm has proposed an audacious plan to send astronauts on a one-way trek to Mars using a pair of tethered U.S. space shuttles that would parachute to the Martian surface.

I'm pretty sure he's not all that serious about it, and mostly threw it out there to generate precisely this sort of publicity. Still, it would beat having them moulder away in museums across the country. However, I'd want some way to get back home before I volunteered for something like that.
