Falcon Heavy To Become World's Most Powerful Operational Rocket

摘要

SpaceX still has some road ahead before Falcon Heavy's debut flight, but the day is approaching. On Dec. 28, the triple-core, 229-ft.-tall (70-m) booster was hoisted vertically for fit checks at Kennedy Space Center's Launch Complex 39A. Two weeks later, fuel flowed into the tanks in preparation for lighting the rocket's 27 first-stage engines together for the first time, a test that likely will be repeated at least once before the Falcon Heavy attempts a liftoff.
