Summary
Pléiades Neo 5 & 6 launched on an Arianespace Vega-C from Ariane Launch Area 1 (ELV), Guiana Space Centre, French Guiana on December 21, 2022 at 01:47 UTC. The mission failed: 2nd stage Zefiro 40 motor lost chamber pressure from T+151 seconds due to unexpected erosion of carbon-carbon (C-C) material in the motor nozzle's throat insert, caused by the material's flaw in homogeneity. It was Arianespace's 312th launch, 5th this year and humanity's 6,364th orbital launch attempt. It was the 2nd Vega-C flight. The payload was bound for Sun-Synchronous Orbit (SSO).
