mission
description

For its 11th launch of the year, and the sixth Ariane 5 liftoff from the Guiana Space Center (CSG) in French Guiana during 2017, Arianespace will orbit four more satellites for the Galileo constellation.

This mission is being performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

For the second time, an Ariane 5 ES version will be used to orbit satellites in Europe’s own satellite navigation system. At the completion of this flight, designated Flight VA240 in Arianespace’s launcher family numbering system, 22 Galileo spacecraft will have been launched by Arianespace.

Arianespace is proud to deploy its entire family of launch vehicles to address Europe’s needs and guarantee its independent access to space.
