Soyuz Galileo launch: injection anomaly

23 August 2014Following the announcement made by Arianespace on the anomalies of the orbit injection of the Galileo satellites, the teams of industries and agencies involved in the early operations of the satellites are investigating the potential implications on the mission.

VS09 flight: Arianespace names independent inquiry commission

Evry, August 25, 2014

Following the major anomaly that occurred on August 22, 2014 during the Soyuz ST mission carrying two satellites in the Galileo constellation, Arianespace announced today, in conjunction with the European Space Agency (ESA) and the European Commission, the appointment of an independent inquiry commission.

The commission is chaired by Peter Dubock, former ESA Inspector General. Its mandate is to establish the circumstances of the anomaly, to identify the root causes and associated aggravating factors, and make recommendations to correct the identified defect and to allow for a safe return to flight for all Soyuz launches from the Guiana Space Center (CSG).

Update on Galileo launch injection anomaly

26 August 2014 Work at ESA’s ESOC control centre continues relentlessly on the two Galileo satellites.

Despite the non-nominal orbit, the satellites are safely under control after they were released from the launcher upper stage and their orbital position was determined by the European ground teams deployed at ESOC in Darmstadt, Germany.

Update on Galileo launch injection anomaly

28 August 2014 Operations continue smoothly for Galileo Sat 5-6. Both satellites now have both sets of their solar arrays fully deployed and generating power.

The satellites are safely under control, despite having been released on a lower and elliptical orbit instead of the expected circular orbit on 22 August.

Galileo satellites status update

16 September 2014 The fifth and sixth Galileo satellites have been in a safe state since 28 August, fully under control from ESA’s centre in Darmstadt, Germany, despite having been released on 22 August into lower and elliptical orbits instead of the expected circular orbits.

The potential of exploiting the satellites to maximum advantage, despite their unplanned injection orbits and within the limited propulsion capabilities, is being investigated.
