Ariane 5 is cleared for launch with the ASTRA 1N and BSAT-3c/JCSAT-110R satellites
Arianespace’s fourth heavy-lift flight of 2011 has been authorized for its August 5 liftoff following today’s launch readiness review at the Spaceport in French Guiana.
With today’s successful review, Ariane 5 is now cleared for its rollout tomorrow from the Final Assembly Building to the Spaceport’s ELA-3 launch zone, where it will be readied for liftoff on Friday during a launch window that opens at 6:53 p.m. local time in French Guiana.
Ariane 5 is to carry a total estimated payload of 9,095 kg. for the upcoming flight – which includes a mass of 8,240 kg. for its ASTRA 1N and BSAT-3c/JCSAT-110R satellite passengers.
ASTRA 1N is located in the upper position of Ariane 5’s payload “stack,” to be released first in the mission at 27 minutes after liftoff. It is a state-of-the-art Ku-band spacecraft for the delivery of pan-European direct-to-home TV broadcast services for satellite operator SES ASTRA.
Ariane 5 will deploy BSAT-3c/JCSAT-110R from its lower payload position at 38 minutes into the flight. This hybrid TV broadcast and telecommunications satellite was manufactured by Lockheed Martin Commercial Space Systems on behalf of B-SAT Corporation and SKY Perfect JSAT Corporation.
Originally scheduled for July 1, this dual-payload mission was delayed to allow a valve replacement for the launcher’s cryogenic core stage.
