Happy Birthday, ESA!
Rendezvous with Halley's Comet
In 1985, ESA launched its first deep space mission with the Giotto spacecraft. Among other things, Giotto was used to research Halley's Comet, which on average passes the Earth every 76 years. It's said the spacecraft was named after the Italian painter, Giotto di Bondone, who had observed the comet in the 14th century.
