Elon Musk has developed rockets that can be used more than once in space, therefore, reusable rockets that are less costly. Most of SpaceX’s funding had come from Musk’s personal savings, and SpaceX and Musk’s other major ventures, not from government contracts or funding. Later on, Musk had initiated a corporate-level strategy where it had developed a lower cost method for rocket launch and offered different rocket production options, meaning increased diversification for its rockets.
