Hanneke Weitering, staff writer for Space.com, breaks down what could go wrong or right during SpaceX's Falcon Heavy launch. The company is planning on launching the rocket from the Kennedy Space Center Tuesday after years of delay.
Weitering says the Falcon Heavy is a "big, awesome rocket" that could eventually take passengers to the moon or even Mars. It was originally set to launch in 2013.
