Nothing anybody ever does in space will ever be more cool than Elon Musk's SpaceX launching a red convertible Tesla roadster, with a mannequin in a space suit posed comfortably in the driver's seat, playing Bowie's "Life on Mars", with a copy of the Hitchhiker's Guide to the Galaxy prominently displaying its soothing "Don't Panic!" cover, with a towel in the trunk (for he is a hoopy frood), and a model of itself being driven by a toy astronaut, out into space, closely past Mars, into an independent solar orbit. With several cameras beaming video back to earth for several hours. And recovering two of the boosters, upright, landing on their tail fins as R.A. Heinlein intended.
Men may do more significant things in space. Men may do more important things. But nobody will ever do something cooler than this.
