Description

The ESA/NASA Ulysses mission has made fundamental contributions to our understanding of the Sun and our local interstellar neighbourhood. Ulysses was designed to last for five years but the mission was extended four times, allowing Ulysses to pass over the Sun's poles for a second and third time, and spending more than 18 years in space.
