The launch of the small rocket “Vega” No. 17 (VV17) failed.
It is highly likely that the cause was an assembly error.

Arianespace traces cause of Vega launch failure to ‘human error’
– Officials from Arianespace —
the French company that manages Vega rocket launches —
said Tuesday engineers reviewed telemetry data and documentation overnight, and found
the most likely cause of the launch failure was a case of human error.
Engineers concluded that
cables leading to thrust vector control actuators on the upper stage were inverted, apparently a mistake from the assembly of the upper stage engine,
according to Roland Lagier, Arianespace’s chief technical officer.
The thrust vector control system
pivots the upper stage engine nozzle to direct thrust, allowing the rocket to control its orientation and steering.
