Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. As the first rocket completely developed in the 21st century, Falcon 9 was designed from the ground up for maximum reliability. Falcon 9’s simple two-stage configuration minimises the number of separation events and with nine first-stage engines, it can safely complete its mission even in the event of an engine shutdown.

With its nine first-stage Merlin engines clustered together, Falcon 9 can sustain up to two engine shutdowns during flight and still successfully complete its mission. Falcon 9 is the only launch vehicle in its class with this key reliability feature.
