Falcon Heavy and Starman
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 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.
Following liftoff, the two side boosters separated from the center core and returned to landing site for future reuse.
Falcon Heavy put a Tesla Roadster and its passenger, Starman, into orbit around the sun. At max velocity Starman and the Roadster will travel 11 km/s (7mi/s) and travel 400 million km (250 million mi) from Earth.
Its first stage is composed of three Falcon 9 nine-engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff, equal to approximately eighteen 747 aircraft. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit. Falcon Heavy was designed from the outset to carry humans into space and restores the possibility of flying missions with crew to the Moon or Mars.
