Finally, and most important, even if Constellation was funded and worked ... so what? The programme was far too tightly focused on repeating Apollo, which was pointless: we already did Apollo! Early ideas of quickly establishing a permanent lunar base had already been forgotten. Constellation was going to deliver exactly what Apollo did: expensive, brief, infrequent visits to the moon. That was all it was good for.
