: For Arianespace, the success of a launch service has always been the top priority. In 2002, the predicted number of flights is very high and we are ready to serve properly the customers as usual. Major steps will be achieved: the consumption of most of the Ariane 4, the first "Ariane 5 10 tons" flight and last, but first of all, the ENVISAT mission on flight V145 have a specific importance. Like many other ESA missions, ENVISAT mission has really been a great challenge. In fact, for almost 10 years, ESA and Arianespace have acted the complete compatibility between the spacecraft and the launcher. As the biggest and heaviest payload ever carried by Ariane, it has been design to fit the new European rocket. Based on the former PPF plateform, it occupies itself the place inside the highest fairing of Ariane 5. With approximately 8.2 metric tons and 10m high, this bird concentrates advanced technologies and will deliver a huge amount of datas. His time has come with 10 onboard scientific experiments to participate in a better understanding of the earth systemic behaviour and future. As never before, computer models will be precisely tuned and will serve differenciate global scenarii which predict future tendencies. As part of the ambitious European GMES (Global Monitoring for Environment and Security) initiative, ENVISAT, ERS, Meteosat or SPOT will contribute to the maximum extent possible. It took nearly 2 months for the complete set of 420 tons of equipments to reach the "Centre Spatial Guyanais" (CSG) using "MN Toucan" Ariane boat, or planes like Antonov or B747-Cargo. Then the payload campaign itself begun on May, the 17th 2001. Unpredicted shorten Ariane 5 mission on july, the 12th 2001, delayed ENVISAT flight to 2002, and gave the campaign a longer and unusual duration. Launcher and customer's teams adapted perfectly and coordinated until the launch. The ENVISAT campaign can be devided in 3 major periods. First period is the customer installation where huge plateforms and tools have been deployed. Then the payload integration itself have been achieved and concluded by fueling and pressurization. At the end, starting from february the 16th, vehicle and payload operations are definitely synchronized during the "Combined Operation Plan" (POC) period which lead to the "lift-off" and the deployment of the payload. The complete success of the mission during the flawless Ariane 5 flight on february, the 28th 2002, confirms that Europe as a all is structured to cope with any ambitious challenge.
