NASA isn't concerned solely with the next program; it also tries to develop technologies that would be necessary decades or more in the future.
To that end, the agency is working now on conceptual designs for space stations in deep space, manned interplanetary craft, and even manned interstellar ships. Such stations and ships would be assembled in space and designed for space. They would never be on a planet during their working time periods. They would be true spaceships.
