'It's less capable than the shuttle, and it has serious pogo problems! Upgrade the shuttle ffs, or am I wrong about this???'
The problem with the Shuttle was it did lots of things not very well. Ares I does at least have a clear mission without all the compromises that so ruined the Shuttle by the time it flew. The Shuttle could have its life extended, but the people who designed it and built it are all now long retired or dead, the production lines and jigs are all long scrapped. There's no going back. And the Soviet Shuttle has long since been broken up (admittedly after a building fell on it).
As for pogo, yes it *could* be a problem. Firstly, to correct the article, the thing wouldn't shake itself to pieces on the pad, pogo is a flight problem.
Secondly, pogo is fixable. Apollo 6, the second flight of the Saturn V nearly ended in disaster because of pogo. There was a violent first stage pogo well beyond what had been seen in Apollo 4. The CSM/LM actually began to disintegrate with quite large chunks coming free. Had the mission been manned the automatic abort would have been invoked. NASA got to work detuning the first stage and had that resolved by the time of Apollo 10's flight.
Second stage pogo nearly destroyed Apollo 13 before its SM oxygen tank had a chance to kill the crew. There was an undiagnosed turbo-pump resonance that caused massive shaking in the central J2 engine. Fortunately the engine's computer noticed an ongoing deviation from preset parameters and initiated a shutdown before pogo tore the engine from its mounts.
Saturn V was never thoroughly de-pogoed, and yet its probably the most successful rocket NASA ever built.
And I never got the chance to see one fired.
