How long has SpaceX been around? Certainly not as long as NASA.
Is NASA planning to back to the Moon? No!
They will put people into space when they get the Falcon 9 man-rated which entails fourteen successful flights with the fourteenth being this next launch.
Their Dragon space capsule has to go through a series of refinements and will be ready for a first flight in two to three years. Once this happens they’ll be flying to the ISS, going to the Moon, and Mars.
Who killed NASAs plans? Why the same guy who handed the contracts to SpaceX.
