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.

Blue Origin's giant New Glenn rocket blasted off from Florida early Thursday morning on its first mission to space, an inaugural step into Earth's orbit for Jeff Bezos' space company as it aims to rival SpaceX in the satellite launch business.
