Summary

This video from the ‘Les Dossiers de l’Espace’ series tells the story of the European Space Agency’s Giotto mission, the first deep-space mission for ESA. It begins by setting the context of solar system exploration in the early 1980s, with the upcoming return of Halley’s Comet in 1986. The video explains how ESA, initially planning a secondary payload on a NASA mission, decided to go it alone after NASA’s shuttle program caused delays. Giotto was designed with a Whipple shield to survive the dusty environment of the comet, and it carried 11 instruments to study the nucleus and coma. Launched on Ariane 1 in July 1985, Giotto flew by Halley in March 1986, coming within 600 km of the nucleus. Despite being hit by a particle that sent it spinning, it survived and transmitted valuable data. The mission continued with a second flyby of comet Grigg-Skjellerup in 1992, after a gravity assist from Earth. The video highlights the scientific discoveries, including the composition of the comet matching solar abundances and the presence of organic compounds, supporting theories about the origin of life on Earth. The mission paved the way for later ESA comet missions like Rosetta.
