You Can't Exert National Prestige With A Rocket That Does Not Fly

NASA's mission to the moon is about far more than cost, Op Ed, Mary Lynne Dittmar/Coalition for Deep Space Exploration, The Hill

"As a result, the role played by national assets in deep space cannot be fulfilled solely by privately owned systems. Bringing someone else's rocket and crew vehicle to the geopolitical table does not convey the same intent. A national presence, backed by the full faith and measure of Congress, focuses international attention and creates incentives for partnerships around the globe."

Keith's note: This is nonsense. In the case of the U.S. the "national asset" i.e. SLS/Orion is billions of dollars over budget and years behind schedule. Meanwhile SpaceX and other private companies could conduct the Orion/SLS plan for lunar exploration far more cheaply and flexibly than the SLS/Orion architecture ever could. Falcon 9/Heavy/Dragon work. SLS/Orion have not yet shown that they can.

It has apparently escaped Dittmar's notice that the original SLS/Orion plan - one that only used SLS and Orion has been continuously morphed into a program that uses more and more commercial capabilities to do the things that SLS/Orion cannot do - either for cost or capability reasons. Were NASA to have relied upon the SLS/Orion "national asset" alone it would have been impossible to meet this Administration's 2024 goal to land humans on the Moon. In fact, even with the shift toward enhanced commercial participation, chronic problems with SLS/Orion system now make it almost certainly incapable of doing its part in the current NASA plan to land humans on the Moon by 2024.

You cannot convey the intended political intent if the rocket you want to use to exert that intent has not flown and will not fly at the cost - or schedule - originally envisioned. Take a look at what European government-backed and Chinese-backed "commercial" companies are doing. They are copying SpaceX - they are not copying SLS/Orion. They learned from American successes - and failures. Can we?
