Ulysses Mission

Ulysses is the first spacecraft to study the unexplored region of space above our Sun's poles. The spacecraft was launched aboard the Space Shuttle Discovery and sent towards Jupiter with powerful booster rockets. After studying Jupiter for 17 days, Ulysses used the giant planet's gravity to hurl it into an orbit out of the Ecliptic Plane, where planets orbit our Sun.

The Ulysses mission was an outgrowth of the abandoned International Solar Polar Mission (ISPM) that involved two spacecraft flying over opposite solar poles to investigate the Sun in three dimensions. Eventually, ESA built a single spacecraft for launch on the Space Shuttle.
