      | THE
          ESA'S ROLE IN SPACE |   
	  |  | Another milestone for the ESA occurred
        in 1986, when the ESA’s Giotto spacecraft, built and launched by European
        technology, made a visit to Halley’s Comet. It was the first attempt
        to reach the comet by any space agency.
 
 Other international accomplishments in space technology include the Ariane rockets
developed by the ESA. Arianes now command the commercial market in space launches,
especially for communications satellites – despite competition from the USA,
Russia, China and Japan. It’s a billion-euro industry.
