(AP) — SpaceX launched its first recycled rocket Thursday, the biggest leap yet in its bid to drive down costs and speed up flights. The Falcon 9 blasted off from Florida's Kennedy Space Center, hoisting a broadcasting satellite into the early evening clear sky on the historic rocket reflight. SpaceX began flying back the Falcon's first-stage, kerosene-fueled boosters in 2015; it's since landed eight, three at Cape Canaveral and five on ocean platforms. Blue Origin, an aerospace company started by another tech billionaire, Jeff Bezos, already has reflown a rocket. During the space shuttle program, the twin booster rockets dropped away two minutes into flight and parachuted into the Atlantic for recovery. SpaceX — which aims to launch up to six reused boosters this year — is familiar with uncharted territory. Besides becoming the first commercial cargo hauler to the International Space Station, SpaceX is building a capsule to launch NASA astronauts as soon as next year.
