Will consider it a win if Falcon Heavy just clears pad: Musk
Ahead of the launch of SpaceX's most powerful rocket Falcon Heavy, Elon Musk has said he would consider it a win if the rocket "just clears the pad". "This is a test mission, so we don't want to set expectations of perfection," Musk added. The rocket, which SpaceX claims is the world's most powerful, is set to launch tonight.
