Man I really wish we would get nuclear propulsion going again one of these days. Fine, fine, not as a launch system, just orbit to orbit... but we could move much larger, more dependable payloads so much further and not have to fiddle with little tweaks like these to surf the tiny margins of chemical propulsion.

It could have been a very mature technology by now. I feel like we created all the nightmares and quit the technology before we got to the actually good uses.
