After taking an extra day to look over the second-hand Falcon 9 following its static fire on 25 May, engineers plan to light the blue touch-paper and stand well back on 1 June.

The night launch, currently scheduled for some time between 0429 and 0657 (UTC) on 1 June, stands only a 40 per cent chance of getting off the ground due to weather constraints, assuming SpaceX doesn't decide to take a bit longer to ensure the rocket's swan song goes to plan.
