Following the last minute abort to the scheduled take off on 1 July ASTRA 1N satellite, SES has pinpointed the cause of the delay.

As reported in Rapid TV News, SES was been forced to abort the launch of the ASTRA 1N satellite, in a dramatic move after discovering an anomaly during the final launch count-down.

Launch service provider Arianespace has concluded an official investigation by deciding 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 (BAF).

Arianespace says that the valve’s replacement and the ensuing operations should require approximately 20 days. It will reschedule the launch shortly.

SES assures that the launch vehicle and its payload, the ASTRA 1N and the BSAT-3c/JCSAT-110R satellite are maintained in fully safe conditions.

ASTRA 1N is scheduled for launch on board an Ariane 5 rocket from Kourou, French Guiana. The new ASTRA satellite was built by Astrium in Toulouse, France, and is intended to first provide interim replacement capacity at the orbital location of 28.2° East. The satellite will subsequently be moved to 19.2° East, from where it will mainly serve the German, French and Spanish markets.
