Arianespace has rolled out its sixth Ariane 5 for its final mission of this year. The launch window on 28 December 2010 is scheduled to begin at 02:26 PM and end at 03:15 PM Phoenix time.

The workhorse vehicle was transferred to the ELA-3 launch zone from the Spaceport’s Final Assembly Building in Kourou, French Guiana, where the Ariane 5 was fitted with its dual-satellite payload of HISPASAT 1E and KOREASAT 6.

Ariane 5’s payload lift performance for this mission is a total of about 9,260 kg., which includes a mass of 8,170 kg. for its satellite passengers, along with the associated integration hardware and the launcher’s SYLDA multi-payload dispenser system.

Riding as the upper passenger in Ariane 5’s payload “stack” is HISPASAT 1E, which will be released at 27 minutes into the flight. This Space Systems/Loral-built satellite weighs approximately 5,320 kg., and is to provide high-quality capacity for Spanish operator HISPASAT’s new initiatives – which include direct to home television; digital terrestrial television; value-added broadband services in mobile, land and maritime environments; and high-definition television.

KOREASAT 6, which has an estimated liftoff mass of 2,850 kg., will be deployed from Ariane 5’s lower passenger position at approximately 34 minutes into the mission. Built by an industry team composed of Orbital Sciences Corp. and Thales Alenia Space for the Republic of Korea’s KT Corporation, KOREASAT 6 is to provide broadcasting and communications services across all of South Korea.

At 2:18 PM Phoenix time (21:18 UTC), we are on hold at T-minus 7 minutes due to weather.

At 2:30 PM, we are still on hold due to weather. All other systems are green.

In the meantime, Arianespace showed a review of the construction of the launch complex for the Soyuz system. The first Soyuz launch from Kourou is scheduled for April 2011. The manifest includes the Pléiades-1, ELISA (4 sats) and SSOT aboard a Soyuz-STA/Fregat vehicle.

At 2:40 PM Phoenix time, we have another 35 minutes in the launch window.

At 2:57 PM, the launch has been scrubbed and rescheduled for the same time tomorrow.
