Giotto (GEM)

A re-examination of Giotto's 1986 encounter with the comet Halley, leading to an account of the Giotto Extended Mission (GEM) - the encounter with the comet Grigg-Skjellerup in 1992. Following the observation of the Halley comet, the Giotto spacecraft flew away, slightly damaged from the encounter, to be re-used 4 years later to observe its second target, comet Grigg-Kjellerup. The video includes a series of very nice images from the observation of the Grigg-Kjellerup comet, turned into animated movies. Also includes very nice animations of ESA’s Giotto spacecraft, as well as the path of Giotto inour solar system. The video also explains the (1) problems of overcoming the damaged parts of Giotto, when to observe the comet Grigg-Skjellerup, and (2) the problems or steering Giotto and changing it direction toward the comet Grigg-Skjellerup .
