Also docked to the space station is SpaceX’s Crew Dragon capsule that ferried four astronauts to the ISS in March, and a Russian Soyuz capsule that delivered three others in September.

The dirty secret of US spaceflight is that it was always private. NASA has never built a rocket that can go to orbit, or orbital crew vehicles. It's all been private contractors, ever since the pre-NASA NACA days.
Some did. Others did R&D work for NASA, which would be made available to the private contractors building NASA's rockets and spacecraft.
