Falcon Heavy - World's Most Powerful Rocket

When Falcon Heavy lifts off later this year, it will be the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit over 53 metric tons (117,000 lb)--a mass equivalent to a 737 jetliner loaded with passengers, crew, luggage and fuel--Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost. http://www.spacex.com/falcon-heavy
