Sorry to say this but this Emperor really has no clothes either and more and more are coming to realise this. The Saturn I/V idea was good for its day when there were no alternatives but we can do better now with what's available.

kraisee - 13/4/2008 8:26 PMYeah, there are easy ways to go down the DIRECT path and still miss the sweet spot.It all depends on the philosophy underlying the decision-making process. Starting with Jupiter-120 and trying to re-develop it into J-232 is the wrong way to o it. Design J-232 first and then fly that in J-120 configuration is the correct way and saves billions.Ross.

I should have realized it as a sign of the apocalypse.

kraisee - 14/4/2008 6:55 PMThose bigger 5-core or even 7-core Delta-IV's aren't safe enough because they are too complicated. There's too much on them to go wrong. I've heard assessments saying 1 in 10 losses for some of them.Ross.
