Launch will be the crucial test of whether engineers have understood the cause of the blast enough to correct it
Space insiders will be watching events in California carefully on Saturday. If all goes well, SpaceX will attempt its first launch since the explosion of 1 September 2016, which grounded its rocket fleet.
The accident destroyed not only the Falcon 9 rocket but also its payload, the Amos 6 communications satellite. It inflicted considerable damage on one of Cape Canaveral’s launch pads too.
