Following a successful launch in the early hours of Wednesday morning (12 March 2025) U.K. time, the PUNCH spacecraft are poised to begin their two-year mission to study the sun's outer atmosphere and its transformation into the solar wind.

The postponement, driven primarily by thick clouds, was the second scrub of the flight since an issue with the rocket on Saturday night.

The missions' first several delays were to allow for additional time for checkouts and processing on the Falcon 9 rocket they'll ride to space, according to NASA. Now, the delay is to "allow SpaceX to complete rocket preparations ahead of liftoff," NASA said in an update.
