摘要

European commercial satellite fleet operators, including the world's four largest by annual revenue, have written the European Space Agency urging that it find immediate ways to reduce Ariane 5 rocket launch costs and, in the longer term, make the next-generation Ariane 6 vehicle more attractive for smaller telecommunications satellites. In an April 8 letter to ESA Director-General Jean-Jacques Dordain, the seven companies comprising the European Satellite Operators Association (ESOA) said the industry is about to be transformed by the arrival of satellites with all-electric propulsion, which for a given amount of capacity are as much as 50 percent lighter than satellites carrying conventional chemical propellant. Signed by die chief executives of Intelsat, SES, Eutelsat, Inmarsat, Hispasat, Telenor Satellite Broadcasting and HellasSat, the letter says Europe cannot wait for an Ariane 6 early in the next decade before attacking its current launch cost problems.
