I give Elon Musk credit for this.
SpaceX saved NASA hinny. After the Space Shuttle, they were totally lost. Sending astronauts to the ISS via Russia?
I also give credit to Amazon’s Blue Origin and Virgin Galactic.
Competition is the way to advance most anything.
Not sure if NASA gave the contract to Bezos for competition or to use him and Blue Horizons to squeeze out the much-hated SpaceX and Musk.
