>…Not rocket engineer either... I think they’ve demonstrated some success with the modular scalable approach. Building a bigger engine would mean basically having to go through the whole design, develop, test, and use process again for just that one component…


Ja in spite of the scary number of nozzles, the whole notion is growing on me.  Mass production is something the rocket industry needs desperately.  There are so many one-time costs in space stuff, so many really big ones, where a facility was built and used for four or six units.  If that can be spread across hundreds of units and we can tolerate a little lower reliability, this might be a great step forward.


Regarding reliability: with our Saturn 5-ish yankee approach, so much of the reliability model was educated guesswork.  With clusters of instrumented engines, you get something the rocket guy loves: data, lots of performance data, frabjous day, callooh callay, reams of yummy data. 


I am still hoping for the best from the air-breathing crowd, but until the Skylon notion is ready to fly, this whole rocket cluster thing might be our best bet for heavy lift.  I count myself as a reluctant Musk supporter.



>…I believe we’re all hoping for success here. If it all goes well, SpaceX will have a Mars-ready rocket. That might mean that Musk’s aggressive plan to put people on Mars in a few years will come to pass.   Dan

Dan I am reluctant to put a turd in the punchbowl, but that humans to Mars notion ain’t happening.  Musk is doing and has done marvelous things.  But that won’t fly.
