ESA Edoardo Amaldi: Third ATV Mission To ISS Moves Ahead

Named after Italian cosmic ray physicist Edoardo Amaldi, the latest Automated Transfer Vehicle (3) will carry dry cargo, water and propellant to the ISS.

The Ariane 5 for Arianespace's third flight to service the International Space Station has begun its build-up at the Spaceport, preparing this heavy-lift launcher for an early 2012 mission from French Guiana with a European Automated Transfer Vehicle cargo resupply vessel.

During activity in the Spaceport's Launcher Integration Building, the Ariane 5's core cryogenic stage was removed from its protective shipping container and raised into position over one of two operational mobile launch tables.

This cleared the way for rollout of the two solid propellant boosters, which will be mated to the core stage.

It is to be followed by integration of the EPS storable propellant upper stage and vehicle equipment bay, completing the basic assembly for the Ariane 5 ES version used on missions with Automated Transfer Vehicles.

The upcoming flight will continue Arianespace's support of International Space Station servicing, orbiting ATVs that support operation of the crewed orbital facility.

The previous Ariane 5 missions with ATVs were launched by Arianespace in February 2011 and in March 2008.

Arianespace’s Ariane 5 mission: ASTRA 3B and COMSATBw-2 satellite payloads

Arianespace’s Ariane 5 mission with the ASTRA 3B and COMSATBw-2 satellite payloads is on track for a liftoff tomorrow evening, following the heavy-lift vehicle’s rollout to the launch zone at the Spaceport in French Guiana this morning.

Riding atop its mobile launch table, Ariane 5 emerged from the Final Assembly Building under a sunny French Guiana sky and was transferred to the launch pad to be secured in place.

This flight will mark another of Arianespace’s missions with a mixed civilian/military payload, as ASTRA 3B is to provide direct-to-home (DTH) services, plus public and private satellite communications for SES ASTRA; while COMSATBw-2 will serve as a secure relay spacecraft for the delivery of key telecommunications capacity to Germany’s armed forces.

Lift performance for the Ariane 5 ECA will be more than 9,110 kg., including approximately 7,970 kg. for the two spacecraft passengers, plus the mass of the vehicle’s dual-passenger dispenser system and satellite integration hardware.

ASTRA 3B is riding in the upper position of the launcher’s payload “stack” and will be deployed at just under 28 minutes into the flight, with COMSATBw-2 located below it in the SYLDA 5 dispenser for a separation at 33 minutes after liftoff.
