The Ariane 5 ECA launch with HOT BIRDTM 7A and SPAINSAT is postponed

Today's Ariane 5 mission has been postponed following an anomaly with ground support equipment that is used to prepare the launch vehicle at Europe's Spaceport.

Both the heavy-lift Ariane 5 ECA and its dual payload of the HOT BIRD 7A and SPAINSAT satellites are in a safe mode.

A new date for this mission will be announced shortly.

The Ariane 5 is cleared for its transfer on Monday, from the final assembly building to the ELA-3 launch zone, where the vehicle will lift off Tuesday evening.

The Ariane 5 ECA will carry a combined payload of 8,985 kg., underscoring the vehicle's heavy-lift capability. Of this total, 7,778 kg. will be for the SPAINSAT and HOT BIRD 7A satellites, while the remaining mass is represented by the payload interface hardware and Sylda 5 dual-payload dispenser system.

SPAINSAT will ride in the upper payload position on Ariane 5, and is to be deployed first in the mission sequence - approximately 27 minutes into the flight. It is the first Spanish satellite dedicated to secure government communications. SPAINSAT will be operated by Hisdesat, a company created in 2001 by Hispasat, INSA, EADS CASA Espacio, Indra and Sener.
The SPAINSAT spacecraft was produced by Space Systems/Loral and will be positioned at 30 deg. West, placing the satellite over the Atlantic. It carries 13 X-band transponders, plus one Ka-band transponder.

HOT BIRD 7A is the lower passenger in the Ariane 5 ECA's payload "stack," and will released at about 32 minutes after lift-off. Operated by Europe's Eutelsat, the satellite will relay television and radio broadcasting from an orbital position of 13 deg. East, which places it above Gabon.
Alcatel Alenia Space produced the HOT BIRD 7A spacecraft, which will be the 21st satellite launched by Arianespace for Eutelsat.

The launch readiness review (RAL) took place in Kourou on Sunday, February 19, 2006 and authorised count-down operations for the SPAINSAT & HOT BIRD7A.

For its first launch of the year, Arianespace will orbit two telecommunications satellites: Spainsat for the Spanish military operator Hisdesat, and HotBird7A for Eutelsat.

The ARIANE 5 "ECA" Launcher lift-off for this Flight is scheduled during the night of February 21 to 22, 2006 as soon as possible within the following launch window:

GMT: From 10:13 p.m. to 11:23 p.m. on February 21, 2006
Kourou: From 07:13 p.m. to 08:23 p.m. on February 21, 2006
Paris and Madrid: From 11:13 p.m. to 00:23 a.m. on February 21/22, 2006
Washington, D.C., U.S.A.: From 05:13 p.m. to 06:23 p.m. on February 21, 2006

The Spanish SPAINSAT governmental telecommunications satellite is being readied for its fuelling as activity continues for Arianespace's first heavy-lift Ariane 5 ECA mission of 2006.

SPAINSAT was transferred within the S5 satellite preparation facility, moving from the S5C hall - where the spacecraft has undergone initial checkout since its arrival in French Guiana on January 24 - to the S5A hall, where the fuelling will be performed.
The modern S5 complex is composed of multiple high-bay clean rooms, all connected by hallways that also are kept at clean room environmental conditions. This enables Ariane 5 mission payloads to undergo the entire pre-launch checkout process - including potentially hazardous fuelling procedures - within the same building. As a result, the satellite preparation process is streamlined, and payloads do not need to make external moves from facility to facility.

SPAINSAT is an X-band satellite to be used in government telecommunications for the Spanish Defence Ministry and operated by Spain's Hisdesat. A portion of its capacity also will be utilised by XTAR, LLC - a joint venture satellite communications company created by Hisdesat and Loral Space & Communications to serve the needs of other government customers.

The SPAINSAT spacecraft was produced by Space Systems/Loral and will be located at an orbital slot of 30 deg. West longitude after launch. Using Ariane 5's unique dual-payload capacity, it will be carried along with Eutelsat's Hot Bird 7A spacecraft.

SPAINSAT arrived at the Spaceport for Ariane 5's dual-passenger mission on January 24th.

Both payloads for Arianespace's upcoming heavy-lift Ariane 5 ECA mission are now undergoing processing at the Spaceport following the arrival of Hisdesat's SPAINSAT satellite in French Guiana

SPAINSAT touched down at Cayenne's Rochambeau International Airport on January 24 aboard an Antonov AN-124 cargo aircraft, and the spacecraft was transported by road to the Spaceport.
After its transfer into the S5 satellite preparation facility, SPAINSAT was removed from the environmentally-controlled shipping container and underwent an initial checkout.

On January 25, an fit-check was made with the cone-shaped adapter that will serve as the interface between SPAINSAT and the Ariane 5 launcher.
The X-band SPAINSAT satellite is to be operated by Spain's Hisdesat for the Spanish Defence Ministry, and will be used for government telecommunications. A portion of its capacity also will be booked by XTAR, LLC - a joint venture satellite communications company created by Hisdesat and Loral Space & Communications to serve the needs of other government customers.
SPAINSAT was built by Space Systems/Loral and will be located at an orbital slot of 30 deg. West longitude after launch. It will be carried on the Ariane 5 ECA along with Eutelsat's HOT BIRD 7A spacecraft, which arrived at the Spaceport on January 19.
Lift-off of the heavy-lift Ariane 5 is targeted for February 21, 2006.

Ariane 5's dual-payload capability is an important part of Arianespace's operational flexibility, allowing the company to pair up satellites on a single flight to meet customers' scheduling and mission requirements.
