Lancement Soyuz VS09 : anomalie d'injection des satellites Galileo.

Les observations complémentaires collectées après la séparation des satellites de la mission Soyuz VS09 pour Galileo FOC M1 mettent en évidence un écart entre l'orbite atteinte et celle prévue.

Des investigations sont en cours. Des informations seront données à l'issue d'une première revue d'exploitation des données du vol, qui se tiendra le 23 août 2014.

VS09 Soyuz launch: Galileo satellites orbital injection anomaly

Complementary observations gathered after separation of the Galileo FOC M1 satellites on Soyuz Flight VS09 have highlighted a discrepancy between targeted and reached orbit.
Investigations are underway. More information will be provided after a first flight data analysis to be completed on August 23, 2014.





Oh look - its a Russkie launch vehicle problem. AGAIN........

Galileo satellites experience orbital injection anomaly
on Soyuz launch Initial report



On August 22, 2014, at 9:27 am local time in French Guiana, a Soyuz ST rocket lifted off with the first two satellites in the Galileo constellation.
The liftoff and first part of the mission proceeded nominally, leading to release of the satellites according to the planned timetable, and reception of signals from the satellites. It was only a certain time after the separation of the satellites that the ongoing analysis of the data provided by the telemetry stations operated by the European Space Agency (ESA) and the French space agency CNES showed that the satellites were not in the expected orbit.

The targeted orbit was circular, inclined at 55 degrees with a semi major axis of 29,900 kilometers. The satellites are now in an elliptical orbit, with excentricity of 0.23, a semi major axis of 26,200 km and inclined at 49.8 degrees.

Both the Fregat upper stage and the two satellites are in a stable condition and position that entails absolutely no risk for people on the ground. The residual propellants on the Fregat stage have been purged and the stage was depressurized normally. According to the initial analyses, an anomaly is thought to have occurred during the flight phase involving the Fregat upper stage, causing the satellites to be injected into a noncompliant orbit.

Studies and data analyses are continuing in Kourou, French Guiana, and at Arianespace headquarters in Evry, near Paris, under the direction of Stéphane Israël, Chairman and CEO of Arianespace, in conjunction with the Russian partners in the Soyuz in French Guiana program (Russian space agency Roscomos and the manufacturers RKTs-Progress and NPO Lavotchkine), as well as Arianespace's customer ESA and its industrial partners, to determine the scope of the anomaly and its impact on the mission. "Our aim is of course to fully understand this anomaly," said Stéphane Israël, Chairman and CEO of Arianespace. "Everybody at Arianespace is totally focused on meeting this objective. Starting Monday, Arianespace, in association with ESA and the European Commission, will designate an independent inquiry board to determine the exact causes of this anomaly and to draw conclusions and develop corrective actions that will allow us to resume launches of Soyuz from the Guiana Space Center (CSG) in complete safety and as quickly as possible. The board will coordinate its work with Russian partners in the Soyuz at CSG program. Arianespace is determined to help meet the European Union's goals for the Galileo program without undue delay. We would like to thank ESA, the European Commission and CNES for the very productive discussions since becoming aware of the occurrence of the anomaly. While it is too early to determine the exact causes, we would like to offer our sincere excuses to ESA and the European Commission for this orbital injection that did not meet expectations."

Not too bad, there should be a reasonable chance of full recovery from that.

The failure was caused by frozen hydrazine fuel lines caused by poor design according to the official report
