Blue Origin will try, try again to launch its heavy-lift New Glenn rocket to orbit for the first time — if the Florida weather cooperates.

The company, started by the Amazon founder Jeff Bezos, reset its countdown clock repeatedly over a period of just over two hours before eventually postponing the test flight to another day.

Jeff Bezos' Blue Origin loaded its New Glenn rocket with propellants on Thursday morning for its debut launch from Florida, its second attempt this week to get the rocket into space and rival SpaceX in the satellite launch market.
