Lanzamiento de otros cuatro satélites Galileo
Finalizada esta misión, serán 18 los satélites del sistema Galileo.
Con los que ya están en órbita, la Comisión Europea podrá declarar el comienzo de los primeros servicios, previstos para finales de este año.

- DescriptionThe recently separated Galileo satellites 15–18 seen in space as four closely clustered dots above their Ariane 5 EPS upper stage, which is venting propellant (the brilliant cloud from both sides of the EPS) as part of its passivation process.The two brighter spots/areas at each side is due to the passivation process itself, in which − after the opening of the valves − the pressure falls quite quickly and therefore a higher concentration of discarded propellant is found further from the EPS.This image was acquired by the CNES/CNRS-operated TAROT telescope on Réunion Island at 17:23 GMT (18:23 CET) on 17 November 2016, approximately 21 minutes after the second separation of paired Galileo satellites. The agile TAROT telescopes are used to hunt out optical evidence of Gamma-ray burst events as well as observe and catalogue space objects in high orbit.About TAROTTAROT refers to 'Télescope à Action Rapide pour les Objets Transitoires – Rapid Action Telescope for Transient Objects' and comprises a network of telescopes, which is jointly operated by the French space agency (CNES) and France's CNRS - Centre national de la recherche scientifique (Artemis and IRAP Laboratories).TAROT consists of two 25-cm aperture instruments located at the Calern Observatory (part of the Observatoire de la Côte d'Azur, France), the La Silla Observatory (European Southern Observatory, Chile), and an 18-cm telescope at Les Makes Observatory (Reunion, France). Since 1999, TAROT has conducted observations of Resident Space Objects (RSO) − mostly debris − on geostationary orbit, and of passing objects in eccentric (such as Geostationary transfer orbit or Medium Earth Orbit). Such observations are used to feed an automatic cataloguing system of RSOs.
