Israeli scientists are set to launch what will be the world's first privately-funded mission to land a probe on the moon.
Propelled by a Flacon 9 rocket made by Elon Musk's company SpaceX, the probe will blast off from Florida at 1.45am UK time on Friday.
The journey to the moon — which involves a series of orbital trajectories — will take two months, with touchdown on the surface scheduled for April 11.
The mission is called Beresheet, named after the Hebrew word for "beginning", the first word in the Book of Genesis.
