Today's launch of a SpaceX Falcon 9 rocket is being pushed back until at least tomorrow 2:48am. SpaceX says the 3:11 am launch from Cape Canaveral was scrubbed due to an issue with the drone ship that recovers the rockets. Meanwhile, SpaceX is confirming that its Dragon crew capsule exploded during a test last month. The company is still trying to figure out what went wrong. The Crew Dragon capsule was scheduled to start carrying NASA astronauts into space as early as this year.
