SpaceX, short for Space Exploration Technologies Corp., is an American aerospace manufacturer and space transportation company founded by Elon Musk in 2002. In just over two decades, it has reshaped the space industry with reusable rockets, crewed missions to the International Space Station, and an ambitious plan to reach Mars.
Here are the real facts behind the headlines, verified and free of hype.
SpaceX was founded in 2002 by Elon Musk, who had previously co-founded PayPal and later became CEO of Tesla. His goal was to reduce the cost of space travel and eventually help make human life multiplanetary.
In 2008, SpaceX's Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit, a milestone that proved private companies could compete with government space programs.
The Falcon 9 rocket is a two-stage vehicle powered by nine Merlin engines on its first stage, burning liquid oxygen and rocket-grade kerosene (RP-1).
The Dragon spacecraft carries cargo and astronauts to and from the International Space Station. It uses a heat shield to survive reentry and parachutes for a safe splashdown.
SpaceX pioneered orbital-class rocket reusability, routinely landing and reflying the first stages of its Falcon 9 and Falcon Heavy rockets to cut launch costs.
Starship is SpaceX's next-generation, fully reusable launch system. Its upper stage (Ship) is powered by six Raptor engines, while the Super Heavy booster beneath it uses 33 Raptor engines.
In February 2018, SpaceX launched the Falcon Heavy for the first time, making it the most powerful operational rocket in the world at that time, capable of carrying payloads of roughly 64 metric tons to low Earth orbit.
That debut Falcon Heavy flight famously carried Elon Musk's own Tesla Roadster as a test payload, sending it toward a solar orbit.
SpaceX did not build the Hyperloop. Elon Musk proposed the high-speed vacuum-tube transport concept in a 2013 white paper and open-sourced the idea; SpaceX later hosted student Hyperloop pod design competitions, but development of the technology has been pursued by separate companies, not SpaceX itself.
In 2018, Japanese billionaire Yusaku Maezawa announced he had booked a Starship flight around the Moon, called the "dearMoon" project, planning to bring artists along as guests.
The dearMoon Moon-flyby mission was ultimately canceled by Maezawa in June 2024 due to repeated delays in Starship's development, rather than flying in 2023 as originally planned.
SpaceX's long-term goal is to help establish a self-sustaining human settlement on Mars using Starship, though the company has repeatedly pushed back its own target dates for crewed Mars missions.
SpaceX's Crew Dragon capsule carried NASA astronauts to the ISS in May 2020, the first crewed orbital launch from U.S. soil since the Space Shuttle retired in 2011.
SpaceX operates Starlink, a constellation of thousands of small satellites in low Earth orbit that provides broadband internet service around the globe.
