I was rather surprised this article failed to mention the RS-84 advanced Hydrocarbon engine design which matched Russian performance and weight parameters; whilst being both available for use on Constellation/ARES, and in a new vehicle had NASA not canceled it as "not needed". Quite so!
I think it's time to get serious about a multi-fuel SABRE engine designed for use as current strap-on solids are currently. An STS type vehicle would be a good starting point...

NASA has experimented with it(Propane/Butane) and Methane fuels but I suspect they found little advantage since they have discontinued serious development - particularly for Constellation.

Utter nonsense! the fundamental HSF techniques worked out through the Gemini program were essential both for Apollo and for future orbital operations like building ISS. Gemini was actually MORE important than Apollo.

There you have it. NASA and Industry failed to match rhetoric, so all practical space applications beyond wideband transmissions and observational capacities remain in the pipe dream category. Of course if government ever decides this is what it needs: just as most of the domestic oil supply is almost exclusively for USG reserve stocks, then we'll see Solar power satellites operating: at huge expense no doubt, with OUR money...

There is one aspect that's not mentioned here; and that is with the '73 ECC opt-in UK lost their prime launch site at Woomera in Australia. Apart from British Giauna where could a UK SLV launch from? It would need to go straight to a RLV configuration and do a few deals with the overfly nations. Definitely a conundrum worthy of consideration: static tests we can do but...
