SpaceX lands its reusable Falcon 9 rocket on a floating drone ship

Elon Musk's SpaceX successfully landed a reusable Falcon 9 rocket on a floating drone ship at sea on Sunday morning. The company's eighth launch this year was part of its ongoing effort to re-use costly rocket parts instead of discarding them into the ocean. It is the fourth time SpaceX has vertically landed a Falcon 9 rocket on a floating platform at sea. The company has also landed another rocket safely on land. The rocket launched under a dark night sky from Cape Canaveral, Florida in the early hours of Sunday morning.
