When Falcon Heavy lifted off, it became the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit nearly 64 metric tons (141,000 lb) a mass greater than a 737 jetliner loaded with passengers, crew, luggage and fuelFalcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost.
