That beast is not needed for moon flight. The new system will be more efficient and especially cool.

And Saturn 5 wasn't cool?

That was designed back in the days when we still needed electricity to operate toasters, for goodness sake.

I used to work Shuttle stuff, I've seen launches live, they are neat. One of my former co-workers worked Apollo stuff "back when." He said the Saturn 5 made the shuttle look like a sparkler.
