It’s tough to say exactly how much it costs to launch a kilogram into Earth orbit, and why. Small rockets offer flexibility, and big ones can have economies of scale. However, take the Delta IV Heavy, built by Boeing and Lockheed Martin. How much of its $350 million cost should be ascribed to the $17 million paid to Lockheed’s CEO in 2018 or to the $30 million paid to Boeing’s? On the other hand, SpaceX has attained far lower launch costs with its Falcon rockets.
