Five for five the fifth Ariane 5 for launch in 2009 is ready for liftoff on September 30 following the integration of its military and civilian telecommunications spacecraft payloads at the Spaceport in French Guiana.
With the Amazonas 2 and COMSATBw-1 satellites installed atop the Arianespace heavy-lift vehicle, this Ariane 5 is now undergoing a last series of checks in preparation for its rollout to the Spaceport’s ELA-3 launch zone.
The Ariane 5 is inside the Final Assembly Building, where Amazonas 2 and COMSATBw-1 were integrated earlier this week (week of September 21).
Upcoming milestones will be the pre-launch readiness review on Monday, September 28, followed by the vehicle’s transfer to the ELA-3 launch pad on Tuesday. Liftoff of the Ariane 5 is planned on September 30 during a 1 hr. 10 min. launch window that opens at 7:00 p.m. (local time in French Guiana).
Amazonas 2 will ride as the upper payload, with COMSATBw-1 positioned as the lower satellite passenger in the Ariane 5’s “stack.” The two spacecraft will be deployed during a mission lasting 33 minutes.
The 5,500-kg. Amazonas 2 is based on EADS Astrium’s Eurostar E3000 spacecraft bus, and will be operated by Spain’s HISPASAT from a final orbital slot of 61 deg. West. This satellite will provide relay capacity over the Americas, with a coverage area extending from Alaska to Tierra del Fuego.
COMSATBw-1 has a liftoff mass of approximately 2,500 kg. and will play an important role in the German Bundeswehr’s (German Armed Forces) concept for network-centric operations. It is to serve as the backbone of a strategic command infrastructure and interface for the Bundeswehr’s tactical arms, handling secure information, including voice, fax, data, video and multimedia applications, for use by units on deployed missions.
The COMSATBw-1 spacecraft’s coverage area will extend from America to eastern Asia. For this German military program, Astrium is responsible for the space segment and is Arianespace’s customer for the commercial launch services. Thales Alenia Space designed, manufactured, integrated, tested and delivered the satellite to Astrium, while Astrium’s German subsidiary TESAT manufactured essential parts of the payload.
