Arianespace has established Friday, April 22 as the new launch date for Ariane 5’s dual-payload mission with the Yahsat Y1A and Intelsat New Dawn satellite payloads from the Spaceport in French Guiana.
This timing was based on the additional checkout and verifications now in progress for the heavy-lift launcher following the final countdown’s interruption on March 30. The interruption occurred when an anomaly was detected during the automated checkout procedure after startup of the Ariane 5’s cryogenic main engine.
The launcher is in the Spaceport’s Final Assembly Building where checkout and verification activity is underway for the mission, designated Ariane Flight VA201 – signifying the 201st launch of an Ariane family vehicle.
With the announcement of this flight’s new liftoff date, Arianespace also has provided timing for the two subsequent Ariane 5 launches:
May 19 for Ariane Flight VA202, utilizing an Ariane 5 ECA to launch the ST-2 and GSAT-8 satellite payloads, and
June 29 for Ariane Flight VA203, with an Ariane 5 ECA carrying the ASTRA 1N and BSAT-3c passengers.
