1992
Ulysses Jupiter Gravity Assist
Oversees the Ulysses Jupiter gravity assist that redirects the spacecraft into a high-inclination solar orbit needed to measure the solar wind over the Sun's poles.
1994
Ulysses South Polar Solar Wind Survey
Uses Ulysses observations over the Sun's southern polar region to show that high-latitude solar wind is fast, comparatively steady and widespread near solar minimum.
1995
Ulysses North Polar Solar Wind Survey
Extends the Ulysses three-dimensional survey across the Sun's northern polar region and confirms the broad dominance of fast polar solar wind during solar minimum.
2000
Ulysses Second South Polar Passage
Directs scientific interpretation as Ulysses revisits the southern solar polar region near solar maximum and measures a more irregular solar-wind environment than during its first polar pass.
2001
Ulysses Second North Polar Passage
Uses the second Ulysses northern polar passage to compare high-latitude solar wind near solar maximum with the simpler fast-wind structure observed near solar minimum.
2008
Ulysses Weak Solar Wind Finding
Reports that long-term Ulysses measurements show the solar wind becoming progressively weaker and reaching unusually low levels late in the mission.
2009
Ulysses Solar Wind Mission Completion
Completes the Ulysses scientific mission after nearly nineteen years of measurements that transformed understanding of the solar wind in three dimensions and over the solar cycle.
