New European Space Agency Contract for Laboratory

WHEN Halley's Comet pays its next visit, in 1986, for the first time since 1910, it will be examined at fairly close quarters (in astronomical terms) by the Giotto scientific satellite. Giotto will take 9 months to reach the vicinity of the comet, travelling at 70km per second. During its flight, it will maintain its stability by spinning at 15rpm.
