Arianespace has announced that the launch of ASTRA 1N has been postponed due to an anomaly that occurred during the final launch count-down on July 1st, 2011. A new launch date will be announced in due time.
Following the anomaly detected on Friday during the launch attempt, Arianespace has decided to replace the valve of the EPC (the main cryogenic stage), which did not function nominally. In order to carry out this operation, the Ariane 5 ECA launch vehicle has been rolled back into the Final Assembly Building.
The valve’s replacement and the ensuing operations should require approximately 20 days. Arianespace will reschedule the launch shortly.
