If you think NASA is frustrated with SpaceX, you're probably right, Ars Technica
"A more blunt assessment was offered by Mary Lynne Dittmar, who is familiar with the thinking of NASA's human spaceflight program managers. "I find it extraordinary that these sorts of announcements are being made when SpaceX has yet to get crew from the ground to low-Earth orbit," she told The New York Times. Dittmar serves as executive director of the Coalition for Deep Space Exploration, the organization formed by the principal contractors behind NASA's SLS rocket and Orion spacecraft. These are the old-guard aerospace firms, including Boeing and Lockheed Martin, whose government contracts are threatened by SpaceX. Orion, in particular, appears to be particularly vulnerable if SpaceX can show that Dragon is capable of performing the same kind of deep space missions and high velocity returns from the Moon. With his latest proposal, Elon Musk is playing a dangerous, but potentially winning, game with his lower-cost alternatives to NASA's existing programs. He recognizes that NASA has nurtured his company, and on Monday night, he remained publicly appreciative of the space agency. However by talking about Mars and now the Moon, he not only indicates that his company isn't entirely focused on its most important contract - commercial crew- but also is making a play for NASA's future deep space exploration plans."
Keith's note: FYI The Coalition for Deep Space Exploration is not an "organization". It is not incorporated anywhere. Dittmar is paid with funds that come directly from these aerospace companies. It is hypocritical in the extreme for her to criticize SpaceX for having not done things when in fact SLS has never flown and a stripped-down Orion test article flew just once on a rocket that it will never fly on again.
Meanwhile, Dragons launched on Falcon 9 rockets have made multiple visits to ISS and Falcon Heavy, composed of three of those Falcon 9's, has a significant flight record and is slated to launch this year - years ahead of SLS. SLS will fly only once every several years until the middle of the next decade - and only once or twice a year after that. Meanwhile Falcon 9s will soon be flying monthly. NASA studies looking at moving a crew onto EM-1 will soon show just how expensive and inflexible SLS/Orion actually is while the Falcon/Dragon product line continues to expand its capability without the ever-increasing costs that plague SLS/Orion.
No one is going to get (back) to the Moon fueled with alternative facts and snake oil.
