Flight VV22 failure:
Arianespace and ESA appoint an independent inquiry
commission
Arianespace announced December
20, the failure of Flight VV22 carrying Pléiades Neo
5 & 6 satellites.
The Vega C launch vehicle
lifted off as scheduled on December 20, 2022 at
10:47 pm (local time in French Guiana). The
lift-off, the mission and the separation of the
first stage (P120C) were nominal. Following the
nominal ignition of the second stage’s (Zefiro 40)
engine around 144 seconds after lift-off, a decrease
in the pressure was observed leading to the
premature end of the mission. Under standard
procedure, the order of destruction of the launcher
was given by CNES, the launch safety authority; no
damage to persons or properties occurred.
Arianespace and the European
Space Agency (ESA) immediately decided to appoint an
independent inquiry commission. This commission is
tasked with analyzing the reasons for the failure
and defining the measures fulfilling all requisite
safety and reliability conditions to allow the
resumption of Vega C flights. Composed of
independent experts, the commission will work with
Avio, Vega C launch system prime contractor.
The inquiry commission is
co-chaired by the Inspector General of ESA and the
Chief Technical Officer of Arianespace. More
information will be shared as soon as the Commission
will have progressed in its investigations.
