1: DOUBLE SUCCESS FOR ARIANE 5
On August 28th, 2002, Ariane 5 scored a double success when it orbited a dual payload of telecommunication and weather satellites for European customers. Lifting off from Guyana Space Center (CSG), European Spaceport in French Guyana, the Ariane 5 carried Atlantic BirdTM 1 for telecom operator Eutelsat, along with the MSG-1 meteorological spacecraft for Eumetsat weather organization. The Ariane launch took place at 6:45 p.m. EDT (22:45 GMT) and both spacecrafts were safely delivered into proper orbit during the next 38 minutes. Flight 155 had been delayed one day following a launch hold due to an indication of a computer dialog problem between the ground network and Ariane 5’s on-board computers. Claudie Haigneré, French astronaut and French Minister for Research and New Technologies, congratulated engineers from CNES (French Space Agency), ESA (European Space Agency), Arianespace and the industry. “The new success of Ariane 5 proves one more time the ability of the European industry and the excellence of Ariane”, she also added.

2: SEVIRI, MSG-1’S EYE
The Spinning Enhanced Visible and Infrared Imager (SEVIRI), the true “eye” of the geostationary Meteosat Second Generation (MSG) satellite will provide European meteorologists with data of an unprecedented accuracy. SEVIRI, which is a joint ESA (European Space Agency) program, has been built by Astrium, a leading space company in Europe. SEVIRI will transmit an image of the Earth every 15 minutes, that is to say two times faster than the former model aboard the Meteosat First Generation satellites. SEVIRI images will be more detailed, offering a geometric resolution of 1 km and will provide data in 12 instead of 3 wavelengths. This will enable all the necessary parameters to be seen such as the temperature of clouds, grounds, oceans as well as the content of atmospheric air masses. Two other instruments built by Astrium have been put into orbit in the course of the year: AMSU-B (Advanced Microwave Sounding Unit) was launched on June 24 aboard the NOAA-M satellite and on May 4, HSB (Humidity Sounder for Brazil) was put into orbit aboard the AQUA satellite of NASA.

3: AT THE END OF 2002, ARIANE 5 WILL HAVE A NEW UPPER STAGE
“The delivery of the first new Ariane 5 upper stage will be an important milestone in the continued development program of the European launch vehicle”, said Astrium project manager Dr. Jens Lassmann on the occasion of ESC-A shipping in Bremen. “Early in September, after the upper stage has arrived at the European spaceport in Kourou, French Guyana, the integration of the complete launch system and thus count down will begin. We assume that this more powerful Ariane version will lift off in the last quarter of the year 2002”, Lassmann continued. In addition to improving performance of the main stage and boosters, the continued development program specifically deals with the development of a new cryogenic upper stage. These measures aim to increase payloads capacity from currently six to ten. Within the framework of the Ariane 5 plus program carried out by the European Space Agency (ESA), Astrium is in charge of the development and construction of the new upper stage. This stage is based on cryogenic propulsion technology and uses super cooled high-energy propellants (liquid hydrogen / liquid oxygen). Using proven components, development time of the new ESC-A was reduced to just over 3 years.
