SpaceX rewrote the economics of spaceflight by landing and reusing rockets that the industry had always thrown away. Its Falcon boosters carry satellites, cargo and astronauts, with Dragon capsules serving NASA and private crews, while the fully reusable Starship system aims to cut launch costs by another order of magnitude. Starlink, a constellation of thousands of satellites delivering internet across the globe, supplies the recurring revenue behind the rocket business. Founded by Elon Musk in 2002, the company listed on Nasdaq in 2026.
