CAPE CANAVERAL, Fla.—SpaceX launched its second supersized rocket and for the first time landed all three boosters April 11, a year after sending up a sports car on the initial test flight.
The new and improved Falcon Heavy thundered into the early evening sky with a communication satellite called Arabsat, the rocket’s first paying customer. The Falcon Heavy is the most powerful rocket in use today, with 27 engines firing at liftoff—nine per booster.
