The first in-flight failure for SpaceX's Falcon rocket family since June 2015, a streak of 344 consecutive successful launches until tonight. A lot of unusual ice was observed on the Falcon 9's upper stage during its first burn tonight, some of it falling into the engine plume.

Upper stage restart to raise perigee resulted in an engine RUD for reasons currently unknown. Team is reviewing data tonight to understand root cause. Starlink satellites were deployed, but the perigee may be too low for them to raise orbit. Will know more in a few hours.

SpaceX had also logged 335 straight successful Falcon rocket missions since the prelaunch explosion with the Amos-6 satellite in 2016. And Falcon 9 Block 5, the most reliable rocket in history, had launched 297 times without a failure until tonight.

Seemed to start around 11:13 in the launch video.

I noticed the ice during the livestream, and wondered the cause — the foggy conditions at launch time? I hadn’t seen that before… (not saying it didn’t happen, just that I never noticed).
