The Hubble is amazing, but i'm not sure how it advanced space flight. wasn't it a shuttle package? ISS was Soyuz and shuttle launches as well, if i recall correctly. So, yes, there is a ton of innovation is space 'stuff'. but space flight? that seems like more of a stretch to me.
Perhaps Delta and Atlas rockets were amazing innovations. They did great jobs with the recent mars missions. I don't recall getting particularly excited for many mars launches. (the missions were cool though).
Those boosters landing together though made me fell like a little kid watching a shuttle launch. But those boosters man. Maybe that's not innovation but that landing sure felt like a big moment to me.
I think the parent poster is trying to say, for a long time it felt like small refinements.
