We don't need to recreate the Saturn IB and Saturn V and instead need the functional equivalent of the Saturn V-B and V-C. Griffin can get rid of the five year gap if he lets go of Ares which is trash anyway and flies the Jupiter 120 and 232 also known as Direct. Direct would be several billion cheaper then Ares in both development and operational costs. This would leave money for important and necessary things for reaching mars such as in space nuclear power for advanced drives such as VASIMR engines. Plus the Jupiter 120 doesn't have thrust oscillation issues like Ares I and can lift even the 5.5M Orion with airbags and cargo. But he's making several bad decisions even recreating Apollo wasn't necessarily the best one since a lifting or biconic vehicle would have been more flexible esp when dealing with skip reentries and landing options. He even made huge mistakes in Orion's development and testing from both a technical and from a public relations stand point. The EELVs could still be used to test the vehicle even if they are not meant to be the crew launch vehicle. All the suborbital Ares I tests are just that PR stunts not real test flights. BTW the Delta IV-H with the latest upgrades can lift nearly 26tons and with a few small GEM SRBs over 30 tons into LEO. With regen RS-68s and the AUS60 upperstage it can lift 45tons. The up coming Falcon 9-H will lift over 28 tons into LEO. Both these vehicles would be much more powerful then Ares I which only lifts 24 tons and thats before they solve the thrust oscillation issues. In short Ares I is pretty much the biggest waste of money in NASA history. He also down played the shuttle program too much since it has taught us more of the skills necessary for reaching mars then the Apollo program. Any manned mission to Mars is going to start out like the ISS project assembling a lot of stuff in LEO. It's just far to heavy to launch all at once unless you have a vehicle like seadragon. We don't need a Spock what we need is a Scotty or better yet a Zefram Cochrane. The big problem is he’s taking the recreating Apollo thing way to literally.

For him the five-year gap is simply a matter of money. There's not enough of it, so end the shuttle flights as soon as possible to free up money for the successor. Logical enough. But, he neatly sidesteps the question of whether he made good choices on the Constellation architecture - and how that is affecting the flight gap.

I always believe that nearly all NASA problems come from the (VERY VERY BAD) decision to develop two (new, very long to develop and very expensive) motor and engine: the 5 (or 5.5) segments SRB and the J-2X these two, new, devices will cause the Ares-1/5 costs to climb up to $30 billion in the next ten years!!! that's why in several articles on ghostNASA.com I still suggest to scrap both things and go back using ONLY ready available, cheap, reliable, man-rated and tested in REAL flights SSME, RS-68 and 4-segments SRB one of my rocket designs that use ONLY standard parts is the Ares 5+ or Ares_33: http://www.ghostnasa.com/posts/032ares5srb3.html . .
