description Giotto Overview

Giotto was a European Space Agency spacecraft launched in 1985 to investigate Halley's Comet during its 1986 return to the inner Solar System. It passed close to the comet's nucleus and returned the first detailed images showing a dark, irregular solid body emitting jets of gas and dust. Despite damage from high-speed dust impacts, Giotto survived the encounter and was later redirected to fly past Comet Grigg-Skjellerup in 1992.

help Giotto FAQ

What was the Giotto space mission?

Giotto was a European Space Agency spacecraft launched in 1985 to investigate Halley's Comet during its 1986 return to the inner Solar System. It passed close to the comet's nucleus and returned the first detailed images showing a dark, irregular solid body.

Did the Giotto spacecraft survive its encounter with Halley's Comet?

Giotto was severely damaged by high-speed impacts from dust particles as it flew within 600 kilometers of Halley's nucleus, knocking out its camera. However, the spacecraft itself survived the encounter and was later redirected to visit Comet Grigg-Skjellerup in 1992.

What agency launched the Giotto probe?

The Giotto mission was managed and launched by the European Space Agency (ESA). It was named after the Italian painter Giotto di Bondone, who famously depicted Halley's Comet as the Star of Bethlehem in a 1305 fresco.

What were the main scientific discoveries of the Giotto mission?

Giotto provided the first clear evidence that a comet nucleus is a solid, dark body composed of frozen gas and dust, rather than a loose cloud. Its images revealed that the nucleus of Halley's Comet is roughly 15 kilometers long and emits jets of gas and dust.
