Artist rendition of the Parker Photo voltaic Probe All of these satellites have observed the Solar with the aircraft from the ecliptic, and so have only noticed its equatorial areas intimately. The Ulysses probe was introduced in 1990 to check the Sunlight's polar areas. It initially traveled to Jupiter, to "slingshot" into an orbit that could acquire it considerably higher than the airplane on the ecliptic.
