Launching human beings on a single SRB is safer? OK, if that's what the consensus is... I'd be happy to "up" on an Ares V but on an Ares I... no,
no-way. Once that puppy's lit ain't no way to throttle it or shut it down... remember STS-107? Well they worked around that particular issue - O
Ring "burn-through" and have a decent "escape scenario"... but on a single SRB the risk of a Criticality One malfunction has less options. If a
single SRB has a "hang-fire" or "chunk-out" or nozzle failure... the vector of escape could well be random - up, down, sideways... bad news for
those on-board. Picture fireworks rockets corkscrewing out of control with humans sittin' on top..
If the US wants to get rid of the OV's, I think it would be good to "keep them around" just in case Ares I has "troubles". The primary reason why
Shuttle is going bye-bye is 43's autocratic myopia.
Shuttle is a good design - dated, yes, but also one of the better understood lift platforms that can handle humans and cargo (lots of cargo) at the
Heard abou the problems with the CEV heatshield designs yet? They can't even test them on the scale required as plasma-arc flames can't be scaled up
to the size needed for testing... a one piece large diameter heatshield... biggest yet and only small sample materials testing and computer sims...
they might get away with it, perhaps not. If they don't... well, that'd be bad - America needs multiple systems to insure success in such risky
