Ulysses Introduction

Welcome to the Web pages of the Ulysses team at Imperial College, London. The purpose of these pages is to introduce the Ulysses mission and the work at Imperial to the general public, and to provide Ulysses-related information for the space science community.

The Ulysses Spacecraft

Ulysses is a joint ESA-NASA mission. The spacecraft was launched in October 1990, and carries several scientific instruments, most of which are designed to study the state of the solar wind as it flows past the spacecraft. The initial part of the mission (to February 1992) involved a cruise to Jupiter. The close approach to that planet then changed Ulysses' orbit drastically, putting it in an orbit which carries it over the poles of the Sun. This allows the spacecraft to measure the solar wind flowing from very high solar latitudes, which had not been achieved previously. Consequently, we have learnt (and are still learning) a great deal about the behaviour of the solar wind flowing from all over the Sun.

The Ulysses Operations Team has an excellent page describing the spacecraft itself.

We have a gallery of images of the spacecraft on the ground and in space.

If you're curious about space science in general, you might want to look at a list of space-related Web links,


The Space and Atmospheric Physics Group at Imperial College has interests in two instruments on Ulysses: the magnetic field experiment and the Anisotropy Telescope. This site has information about both instruments.
