Orion Spacecraft On the Path To Future Flight 135

In the meantime, the Dragon capsule being designed by SpaceX is making it first real flight next month. Heck, it is already at the cape ready for launch, and all they are doing now is a waiting game to get a launch slot to open... and some last minute tests to take care of some engineering questions they have about the rocket. This is both a test for the Falcon 9 (its second flight) and the capsule, but in this case they are doing some in-orbit testing of the avionics, the Draco thrusters, and the heat shield for re-entry purposes. They are also testing recovery procedures in what is for now an unmanned vehicle.
I'd have to agree that the timing of this is a little suspect, and the rocket that the Orion is supposedly going to be flying on has yet to even be approved for funding in the first place. The Obama administration may be eying a variant of DIRECT right now, but that isn't really ready for prime time. Boeing, on the other hand, is going to be flying their CST-100 on a Delta IV. That is a proven rocket system with over a dozen flights to certify its reliability and to work out the bugs in terms of getting things into orbit.
The question for what the Orion is going to be flying on in order to make this test is a very real question that ought to be asked. Perhaps a heavy launch variant of the Delta IV, Atlas V, or the Falcon 9 might be able to get it up into space, but there was some explicit engineering done on the Orion vehicle to make sure it couldn't fly on the EELVs. Yes, this was by design and it was done to make sure it had to fly on the Ares I rocket. How Lock-Mart is going to refit this to fly on something else is going to be real interesting. I thought they were well past the raw specification stage and were making mock-ups and building actual hardware.

If you can define man-rated, I'll bite here. Both the Delta IV and the Atlas V have enough thrust to place a capsule like the Orion up into orbit, or at least a manned vehicle.
I should also point out that it was an Atlas launcher (admittedly a predecessor to the current Atlas V) that has already seen service in the manned spaceflight program for NASA: It put John Glenn into orbit! Seriously, the argument that these vehicles aren't man-rated is overblown and isn't even a realistic argument here.
If you are willing to trust sending into orbit billion dollar payloads that represent a million man-hours of effort or more, that is something that at least exceeds the safety margin given for Shuttle launches and is likely to be better. There may need to be some minor tweaks to finish any honest assessment to make these vehicles man-rated, but that is very trivial compared to what is needed to get a brand-new launcher up to speed and rated for carrying astronauts. The NRO wouldn't have been sending their satellites up on these launchers if they weren't reliable.

It isn't really cheaper at all. Cost is not a driver here, but rather continuing to employ people in key congressional districts so NASA can gets its appropriations bill passed.
As for the factories making the tanks getting a retooling.... it is going to happen anyway. The external tank production line at Michoud has been shut down.... with a big New Orleans style parade with the final tank going down to the port and sailing off for Florida. The employees have been laid off and most of them have gone on to other jobs. There still is a crew left at the Michoud facility as there were other things going on besides the Shuttle contracts, but that was a major part of the work force there. They were going to be gearing up for the Constellation projects and specifically the Ares V, but I suppose that isn't working out so well either.
As for the ATK rockets produced at Promontory, Utah, those employees have also been laid off and many have moved onto other things. ATK landed a cute little contract for the Air Force that is sucking up those employees that they didn't want to let go and were still receiving Constellation funding (the funding is still flowing the the system).
I suppose the raw engineering has been done and there is a modest saving there, but having to bring back and train a whole new production crew from scratch sounds like an incredibly expensive proposition... especially if the funding for this is as shaky as I've ever seen any sort of project funding.
