When the firm SpaceX launches its Falcon Heavy rocket into space late this year, the craft will become the mightiest rocket in the world. Only NASA’s Saturn V, which sent Americans to the moon, has ever generated more power. In rockets, the most important measure of power is thrust. Falcon Heavy’s 27 individual booster engines together generate 3.8 million pounds of thrust—enough to lift the 3.1-million-pound rocket and its 117,000-pound payload toward low-Earth orbit.
