This week marks the 25th anniversary of the launch of Giotto, the European Space Agency’s mission to Comet Halley.
Giotto was one of a small number of spacecraft sent to the famous comet, flying close by its nucleus and sending back remarkable, first-ever close-up images of a comet.
This video was released in 2006 to commemorate the 20th anniversary of Giotto’s encounter with Halley, and details the many extraordinary things that were learned.
