The Falcon 9 is a two-stage orbital launch vehicle developed by SpaceX capable of delivering payloads to low-Earth orbit, geostationary transfer orbit, and beyond. Its first stage is designed for vertical landing and rapid reuse, dramatically reducing launch costs and enabling high flight cadence for commercial, government, and scientific missions.

The vehicle has flown hundreds of missions for NASA, commercial satellite operators, and defense customers. Vertical takeoff, vertical landing architecture, and rapid refurbishment cycles make Falcon 9 one of the most frequently flown orbital rockets in history, supporting crewed Dragon capsule launches under NASA's Commercial Crew Program.
