The launch of the Astra 3B satellite has been rescheduled for May 21, after launch company Arianespace completed work on the Ariane 5 rocket’s troublesome helium pressurisation system.
Astra 3B, and its co-passenger ComSatBw-2, have been delayed three times as Arianespace made attempts to make its first launch of 2010. The faulty pressure regulator was also blamed for delays to the Helios 2B satellite that was the final launch of 2010.
Following the delays a comprehensive task force was established involving representatives from Astra, Arianespace, ESA, CNES, EADS Astrium, and associated technical partners.
The 50th mission for Ariane 5 has now been scheduled for a window that opens at 22.01 GMT on May 21. However, Arianespace is continuing with a report into the overall quality of its launch vehicle.
