Skylab
When Zubrin was out here (in 2000 if I remember) he said that Skylab - launched by a modified Saturn V - had the the equivalent internal work/habitat space as the ISS. I don't know if he meant the ISS at its then stage of development, or the projected ISS at completion. But the lesson is clear.
.. well at least we got all those terrific unmanned missions - how many since 1972? Five Mars landers - all NASA - .. various Mars orbiters, Cassini, Galileo, the amazing Voyagers, etc. etc.
Hopefully NASA is not really dead - just 'resting after a long squawk' (apologies to Monty Python's parrot sketch)
