SpaceX has justannounced its comming rocket - the Falcon Heavy - wich will be the markets largest rocket in terms of payload capacity

Falcon Heavy, the world’s most powerful rocket, represents SpaceX’s entry into the heavy lift launch vehicle category. With the ability to carry satellites or interplanetary spacecraft weighing over 53tonnes to a Low Earth Orbit (LEO), Falcon Heavy can lift nearly twice the payload of the next closest vehicle, the US Space Shuttle, and more than twice the payload of the Delta IV Heavy.

With over 3.8 million pounds of thrust at liftoff, Falcon Heavy will be the most capable rocket flying. By comparison, the liftoff thrust of the Falcon Heavy equals fifteen Boeing 747 aircraft at full power.
