Ares V – Ares 1 = Ares IV

Keith’s note: Sources report that Steve King and his team are now focusing on a so-called Ares IV architecture – a smaller, less powerful version of the Ares V – one that would keep the current Ares-1 upperstage. Boeing seems to be in favor of this option rather than one that would use EELVs. The Ares IV would be used to launch crew or cargo missions. Of course, Cook is convinced that he will be put in charge of this new effort now that his Ares 1 project has all but failed to deliver. Stay tuned.
