Musk said in a tweet that SpaceX has pinpointed the problem to be the hydraulic fuel located within the tailfin, which allows Falcon 9 to rotate and spin. The company discovered that the tailfin ran out of fuel and could no longer stabilize itself.
Reusable rocket technology could drastically cut the cost of spaceflight travel.
Space X plans on using the same drone barge for their next launch on January 29.
