The Ariane 5 ECA is an improved Ariane 5 Generic launcher. Although it has the same general architecture, a number of major changes were made to the basic structure of the Ariane 5 Generic version to increase thrust and enable it to carry heavier payloads into orbit.<\/p>\n
Designed to place payloads weighing up to 9.6 tonnes into GTO, this increased capacity allows the Ariane 5 ECA to handle dual launches of very large satellites.<\/p>\n
During the initial countdown on March 30, all was green through to main engine ingition, with the Vulcain main engine igniting and ramping up to full power \u2013 as designed.<\/p>\n

However, instead of the twin solid rocket boosters then firing to launch the vehicle, some seven seconds later, the vehicle remained on the pad, with the main engine still firing for what appears to be at least another ten seconds.<\/p>\nSpace Shuttle

With the vehicle in a pad abort stance, safing was undertaken, with both the vehicle and its passengers secured.<\/p>\n
The launch was delayed to April 22, due to the need to rollback the vehicle to its integration center for investigations and reconfiguration \u2013 given the umbilicals were all released during the pad abort.<\/p>\n
Overview:<\/p>\n
The 57th launch of an Ariane 5 \u2013 designated as VA201 \u2013 will carry a total lift performance of nearly 10,065 kg, which includes the combined 8,965 kg liftoff mass of the two spacecraft passengers, along with the SYLDA dual payload dispenser and integration hardware.<\/p>\n

With a liftoff mass of 6,000 kg, the Yahsat Y1A spacecraft is based on Astrium\u2019s Eurostar E3000 platform.<\/p>\nYahsat Y1A is the initial telecommunications relay spacecraft for Al Yah Satellite Communications Company (Yahsat), and it was built by an industrial team of EADS Astrium and Thales Alenia Space \u2013 which have the responsibility of co-prime contractors.<\/p>\n
Astrium is the lead for a turnkey delivery of the two-satellite Yahsat system, while Thales Alenia Space is in charge of the launcher procurement.<\/p>\n
With a payload of Ku-, Ka- and C-band transponders, the spacecraft will provide coverage over the Middle East, Africa, Europe and Southwest Asia.<\/p>\n

Intelsat New Dawn is the first-ever African private sector communications satellite, with the mission of supplying critical communications infrastructure for African customers. To be marketed and operated as part of the Intelsat satellite fleet, Intelsat New Dawn will deliver wireless backhaul, broadband and media content \u2013 which are the fastest growing satellite-based applications in Africa.<\/p>\nProduced by Orbital Sciences Corporation in Dulles, Virginia, the relay platform carries C-band and Ku-band transponders, and will have a liftoff mass of 3,000 kg. After its deployment by Ariane 5, it will be positioned at a geostationary orbital slot at 32.8 degrees East for its Africa area coverage.<\/p>\n
The latest Ariane flight will keep up the mission pace for Arianespace during the year, in which the company is targeting a total of 12 launches \u2013 composed of six Ariane 5 flights, the first two Soyuz launches and Vega\u2019s inaugural liftoff, all from the Spaceport; along with three Soyuz launches from Baikonur Cosmodrome in Kazakhstan.<\/p>\n
At the Spaceport, another Ariane 5 mission is also taking shape for a May mission with the ST-2 and GSAT-8 satellites \u2013 with initial assembly completed. The Spaceport is designed for such parallel mission operations, enabling two Ariane 5s to be prepared for flight.<\/p>\n
