Officials are attributing the loss of the rocket to a "series of human errors".
According to satellite launch company Arianespace, the trouble began around the eight-minute mark of the mission.
Eight minutes into its flight, after igniting its upper engine stage, the Vega rocket veered from its planned course and lost contact with ground tracking stations. However, as soon as the first ignition was completed, the AVUM certainly went unrecovered. The upper stage and its cargo - the Spanish SEOSAT-Ingenio Earth observation satellite and the French TARANIS atmospheric observation satellite - plunged into an uninhabited area, said an Arianespace statement.More news: Hurricane Iota impacts 357,339 people in Honduras
Telemetry data are now being analysed by teams from Arianespace, Avio, Cnes and the European Space Agency in an attempt to identify the reasons for the launcher's dramatic failure. The cables connected to a pair of thrust vector control actuators were upside down.
Preliminary investigations revealed that the incident possibly occurred because of human error, rather than faulty design. Arianspace and ESA will jointly present the findings of this commission.
"We can unfortunately confirm that the mission is lost", Stéphane Israël, the CEO of Arianespace, said during a live stream of the launch last night.More news: Fauci 'Concerned' About Transition Affecting Vaccine Rollout
On 11 July 2019, it was the second stage of the launcher that caused the failure of flight VV15, which carried the Emirates' Falcon Eye 1 optical reconnaissance satellite.
The rocket that failed is called Vega, one of the primary rockets developed by European launch provider Arianespace. Arianespace attributed that incident to a structural problem with Vega's second stage, which has since been resolved.More news: The inflation rate in Great Britain rises to 0.7%.
