Incorrect. I quite accurately pointed out that Findley was incorrect
when he suggested that the Shuttle and the Ares 1 faced the same sort
of problems. The fact is... they *don't.* Shuttle started off as a
vastly more ambitious and complex concept than Ares did.

Ares I/V are most certainly less complex than the entire shuttle system.

And otherwise almost wholly different in design and concept to the
shuttle. The engineering challenges are not the same.


The long pole in the tent, last I checked, is the J2-X.

Which will be needed anyway for Ares V.

The biggest unknowns are likely from the components that aren't shuttle
derived (i.e. the J2-X), but I wouldn't count out significant teething
problems with the 5 segment SRB's either.

I would be surprised if *significant* issues arose. A five-segment RSRM
was slapped together and put on the stand, and it ran fine; nothing
about it was optimised. Hell, they made a bigger-throated-nozzle for
the 5-seg by the simple expedient of machining out several inches of
graphite from the existing RSRM throat, and it didn't even disintegrate.
