just keep coming (we hope). SpaceX 's most powerful rocket -- the Falcon Heavy -- was primed to send Saudi Arabia's Arabsat-6A telecommunications satellite into orbit Wednesday, but high atmospheric winds forced SpaceXto postpone the launch by 24 hours. Now the moment has (almost) arrived (again). On Wednesday Elon Musk, SpaceX CEO suggested that a delay was likely due to "upper atmospheric wind shear" and SpaceX confirmed there would be no launch. Instead, the company would aim for their backup window, which is scheduled to open at 3:32 p.m. PT on April 11 and will remain open until 5:32 p.m. PT. SpaceX tweeted Thursday "all weather and systems are currently go", so provided the pesky Floridian weather stays that way, it should be full steam ahead. All systems and weather are currently go ahead of tonight’s Falcon Heavy launch of Arabsat-6A from Pad 39A; launch window opens at 6:35 p.m. EDT, or 22:35 UTC → https://t.co/gtC39uBC7z
