SpaceX’s long awaited Falcon Heavy  launch is scheduled to leave from launch pad 39A today, but due to “upper level wind shear,” SpaceX has pushed back the launch time to 3:15 p.m. ET. The launch window is scheduled to close at 4 p.m.

It’s the third delay today as unacceptable levels of wind has caused concern over whether launching today will be possible for what will be the most powerful rocket launch since the Saturn 5 program.
