SpaceX was founded in 2002 by Elon Musk with the goal of reducing space travel costs to enable colonization of Mars. It has developed reusable Falcon launch vehicles and Dragon spacecraft, and plans future vehicles like the Mars Colonial Transporter. Financially, SpaceX has raised over $1 billion from investors and is currently valued at $10 billion. While reusable rockets have shown promise, the first live landing attempt failed. SpaceX aims to provide low-cost internet access worldwide via a satellite constellation. It faces competition from companies like Boeing and Lockheed Martin but has an advantage due to lower costs and faster development. The author predicts SpaceX will help land humans on Mars by 2025-2030.
