英文原文：
Elon Musk, the billionaire entrepreneur and founder of space company SpaceX, posted a video on Instagram where he shows a Falcon reusable rocket exploding after coming back from space and attempting to land on a drone ship.
According to Musk, one of the legs failed to lock and caused the whole rocket to tip over.
Rough seas at the time of the mission may have also contributed to the unsuccessful landing.
But for Musk, this is far from being a real failure.
The company has a few more ocean missions coming up and, according to his post on Twitter, Musk remains positive that landing rocket ships will soon become a reality.
