Per Boek Wijzer Auteur: Nigel Calder
On io July 1992 Europe's spacecraft Giotto, battered but still functional after its historic encounter with Halley's Comet, flew through Comet Grigg-Skjellerup. It was the culmination of a seven-year odyssey. Giotto to the Comets is an account of the double mission, drawing on interviews with the men and women who accomplished it in the face of often daunting difficulties. The book also tells why comets are prime objects for anyone who wants to un-derstand the creation of the world. Now that we know what a comet nucleus looks like and what it is made of, we face provocative new questions about the influence of comets on the Earth, its atmosphere and oceans, and its delicate film of life. In Giotto to the Comets Nigel Calder returns to the cosmic arena of several of his best-known books: Einstein's Universe, Spaceships of the Mind, Violent Universe, and The Comet is Coming!
