SpaceX

SpaceX has become the most successful private aerospace company in history, pioneering commercial orbital launches, reusable rockets, and low-cost access to space.

It was the first private firm to deliver cargo and then astronauts to the ISS, and its Falcon 9 rocket now dominates the global launch market.

Through innovations like Starlink, SpaceX has expanded into satellite internet, while Starship development positions it for deep space missions.

Its success has reshaped the industry, proving private companies can outpace traditional government contractors in both innovation and cost-efficiency.
