The Ulysses probe is launched by the Space Shuttle Discovery (STS-41). Two years later, it will pass near Jupiter for a flyby that will place it into an orbit inclined 80 degrees to the ecliptic. It will observe the solar poles three times (1994-95, 2000-01, 2007-08), discovering that the magnetic field at the solar poles is much weaker than previously simulated, and that there is thirty times more extrasolar dust outside the ecliptic than previously suspected.
