The only vehicle in the works to boost humans to the moon is SLS. Ready for testing since 2104 ... it has never been test launched. It has never even passed a single ground test.
The Orion spacecraft meant to take men to The Moon was launched once, unmanned in 2014. Never again flown.
The planned lunar lander isn't even in prototype stage. There were plans to outsource the lander to SpaceX, those plans have been scrapped and no new contractor has been chosen
The Artemis Program, which claims a target of 2024 for first moon landing. Has no tested launch vehicle, no tested CSM, and no lander less than 2 years before their target.
The Apollo program had all three well in advance of the Apollo 11 Landing (which could have happened on Apollo 10).
There is no will, national or political, to ever seriously go into space again.
The only way any American will see space for the next 50 years is at the next installment of the "Star Wars" franchise.
