Which spacecraft first observed the north pole of the Sun from above the ecliptic plane?
Quick Answer
ESA and NASA’s Ulysses spacecraft was the first to study the Sun’s polar regions from a high-inclination orbit. It used Jupiter’s gravity in 1992 to tilt its path.
The Full Story
Ulysses was the first spacecraft to make repeated passes over the Sun’s poles by moving into a highly inclined solar orbit. After a gravity assist from Jupiter in 1992, it entered an orbit that took it well above and below the plane of the planets. This let scientists study the Sun’s poles, solar wind and heliosphere in ways impossible from Earth. Ulysses operated for almost 19 years and reshaped understanding of the Sun’s large-scale environment.
