The commission set up by the
European Space Agency (ESA) and
Arianespace to investigate the Vega launch failure in November has released its findings. Arianespace CEO Stéphane Israël said in a Dec. 17 press release that the findings may allow a return to flight for the Vega by the end of the first quarter of 2021.
The commission reported that the failure was caused by wrong routing and connection of the control lanes of the electro-mechanical actuators of the Attitude Vernier Upper Module (AVUM) upper stage Thrust Vector Control (TVC) system. This inverted steering commands caused trajectory degradation, which led to the loss of the vehicle.

PARIS, 17 December 2020 On Tuesday, November 17, Arianespace announced the loss of the Vega VV17 mission, which was carrying two payloads, SEOSAT-Ingenio, an Earth-science observation satellite for the European Space Agency (ESA), on behalf of Spain’s Center for Development of Industrial Technology (CDTI), and TARANIS for France’s National Centre for Space Studies (CNES).
The first three stages functioned nominally until the ignition of the AVUM upper stage, eight minutes after liftoff. At that time, a degraded trajectory was detected, followed by a loss of control of the vehicle and the subsequent loss of the mission.
