I remember the Apollo flights very well and especially the J flights.
They were spectacular and as scientifically oriented as they could !

Well, the HST's pictures and maintenance repairs recapture the 70's Apollo spirit in that the telescope is producing a huge amount of scientific data while enabling us to enjoy great manned missions.
It's not about geology (or selenology) but about astronomy and cosmology

And if we keep regretting the Moonflights and dream about a Manned mission to Mars while not paying much attention to the HST (combined with Shuttle) feats, than we have missed the point.
I hope the HST goes on working until the Webb telescope becomes operational.
