Does that also effect the Lagrange points for the moon? Do human currently have anything parked at earth moon lagrange points?
"the radius for a selenostationary orbit is much farther than the Hill radius, meaning that no stable orbit can be achieved as it would be too much perturbed by the Earth and/or the Sun"
"all of the Lagrangian points of the Earth-Moon system are stationary relative to the Moon surface"
...but then it is explained that stationary doesn't mean stable.

Conversely landing on the moon and returning to Lunar orbit takes 1.72 km/s twice, which is again consistent with my numbers if we assume the payload mass is constant. That may not be the case of course but any cargo taken from the Lunar surface to Lunar orbit will also need to be brought back to Earth somehow.
It will either be discarded after use or refueled and reused fully in space.
But yeah, I think SpaceX will prove it all works and then NASA has the option to change the plan. In the meantime, officially keeping SLS keeps Congress happy.
