The law says SLS with Orion as backup. Ridiculous and not human rated until the next upper stage, so you can't do it before 2020, with unlimited funds.
Well SLS could, and should have been in launch test mode this year....lets not go there.
Orion has been under development one way or another for how many years? Frankly, the 2010 Obama plan confirmed Orion as a backup and should be ready....but this is all the Administration and politics, so lets not go there.
If DoD had invested on a bigger cache of RD-180, or us production this would not an issue. If they had worked on human rating the Delta IV before, it wouldn't either. But even the ICPS has dropped the human rating requirement. So as of right now it simply isn't an option.
If you wanted to go with Delta IV Heavy, you'd still have to human rate it.
If you look at our status I don't see any other choice.
That's not right. Falcon 9 is closer to human rate. And there's the option of producing the engines in the US.
Those schedules and cost would make it easier to actually produce the RD-180 in the US. Again, no funding limits.
That's a given....its time for Rocketdyne to pull all the materials out of storage and get the manufacturing project started.
It needs the funding. 200M have been appropriated this year. But it's a long road and we don't know what will happen with the project if the Ukrainian crisis gets solved next year.
If funding is an issue, I don't believe there's any human rated alternative to Atlas V save for Falcon 9, and Dragon has the integration advantage there.
Where is this coming from? The Falcon 9 is under continuous experimental status with re usability. Unless I missed something, don't see this combo operational as HSR for years. Throwing more cash is not going to fix this problem.
Dragon on Falcon 9 is about to go through integrated CDR in a couple of month. They are actually testing the MaxQ LAS abort this year or early next. And they have agreed their certification process with NASA. Do you believe that you can be the fore runner in crewed launch competition with a rocket that's nowhere close to human rating? If Atlas V was the closest to human rating, then Falcon 9 is clearly next.
Regarding NASA rockets, yes, the problem is propulsion. Not only human rated but nuclear rated. ULA could deploy a Delta IV (4,4) in 36 months and a (5,6) or (5,8) in 48 months. That could cover Atlas V 431, 541 and 551, resp. But again, look at lead times. And is not only certifying for launch, but human rating and nuclear rating. Of course ULA can pump the cores, and the cost would go down for Delta (though higher than Atlas V). But the engines stock in simply not enough to deploy the alternatives without some painful decisions.
We are at the pre to painful decisions point. Start thinking of it as a management lead Apollo 13 issue. So a decision is needed, the Sooner the better.
Believe the real call NASA needs to make is going from the RS-68 A to make the RS-68B. The electronics upgrade is done? The regenerative nozzle would finish the project?
The RS-68A project actually took care of most of the human rating issues. Going to a full new development like the RS-68B would not only be seriously expensive, but add three to five years to the human rating effort. As the Delta IV current status, is mostly implementing Common Avionics, pad mods and design and implement the certification process. The issue is mostly the avionics implementation schedule.
The issue with the rest of the crew rating is simply money and time. Had CST-100 or DreamChaser chosen the DIV, they would have done all the requirement and planning that would have allowed them to launch crew in a couple of years. But they haven't and no amount of money can accelerate certain thing. In any case nowhere close to Falcon 9 readiness.
But, to be frank, I don't expect this situation to keep going for more than two days.
What can be solved in two days?
I'm sorry, I meant two years. I'm referring to the Ukrainian situation.
