SpaceX SpaceX’s Falcon Heavy center core goes overboard, Elon Musk still hopeful Pictured here is B1050 in late 2018. The center core of SpaceX's second Falcon Heavy rocket sits atop the drone ship Of Course I Still Love You after the successful launch of the Arabsat 6A satellite April 11, 2019. The center core that was lost is one of three that the Falcon Heavy rocket uses to boost heavier payloads into orbit. SpaceX's next Falcon Heavy mission, slated for this summer, will use a new center core, so the loss of the core from last week's mission won't affect it. SpaceX Falcon Heavy's pulls off most difficult launch ever but loses core booster. SpaceX has completed the first static fire test of the Falcon Heavy’s center core, bringing the ‘world’s most powerful rocket’ a step closer to its maiden launch.
