The greatest achievement the Shuttle program managed, was the deployment, saving and maintenance of the Hubble Space Telescope. Of course, the construction, transportation and deployment and building of the ISS was a monumental achievement with benefits to humanity blossoming each day, but regardless its existence and utility, we would be in the dark about much bigger issues without the Hubble. In fact ー short of a world-culture-shocking chemical, physical or otherwise artifactual discovery via human or robotic exploration on another celestial body, the discoveries made and yet to beーabout and in space by other meansーare to be dwarfed by those of the Hubble.
