SpaceX launches and lands a used rocket for the second time
Elon Musk-led space exploration startup SpaceX on Friday successfully launched and landed a recycled Falcon 9 rocket for the second time. The rocket's 14-storey-tall core that houses the fuel and the rocket's main engines, touched down on one of the company's autonomous drone ships shortly after taking off. It's the 12th time SpaceX successfully landed one of these rocket stages.
