From a launch pad at the Kennedy Space Center on Sunday, Elon Musk's SpaceX launched its latest rocket test into the Florida sky. Less than two minutes later, it exploded — just like the company hoped it would.

The explosion itself wasn't so much the success as was what came just before it. That's when the Crew Dragon, a capsule meant to carry astronauts into space, separated from the rocket. That separation was the goal of Sunday's test.
