SpaceX Heavy
Quote:
SpaceX's big new rocket has blasted off on its first test flight, carrying a red sports car on an endless road trip past Mars.
The Falcon Heavy rocket rose on Tuesday from the same Florida launch pad used by NASA nearly 50 years ago to send men to the moon. With liftoff, the Heavy became the most powerful rocket in use today.

Quote:
Falcon Heavy is designed to place up to 70 tonnes into standard low-Earth orbit at a cost of $US90 million per launch. That is twice the lift capacity of the biggest existing rocket in America's space fleet - the Delta 4 Heavy of rival United Launch Alliance (ULA), a partnership of Lockheed Martin Corp and Boeing Co - for about a quarter of the cost.

still, doens't match the Saturn V rockets
Quote:
Saturn V
Even after the Falcon Heavy launche, the Saturn V will remain the tallest and most powerful rocket ever, and the only one to help carry humans beyond Earth's orbit. NASA used the Saturn V to send astronauts to the moon in the Apollo 11, 12, 14, 15, 16 and 17 spacecraft.
A Saturn V also launched Apollo 13, but the spacecraft (not the rocket) had a problem and the astronauts didn't land. The last Saturn V was used to launch Skylab, America's first space station, on May 14, 1973.
