Ulysses is charting the unknown reaches of space above and below the poles of the Sun. In particular, the satellite is studying the solar wind that blows nonstop from the Sun and carves a huge bubble in space called the heliosphere. Ulysses is providing the first-ever map of the heliosphere from the equator to the poles..

			Ulysses was launched towards Jupiter in October 1990, after being carried into low-Earth orbit. Following the fly-by of Jupiter in February 1992, Ulysses is in a 6.2-year solar polar orbit inclined at 79.40 with respect to the ecliptic plane.
			Tracking and data gathering by NASA's Deep Space Network, which is operated by Jet Propulsion Laboratory in California. Spacecraft operations and data analysis are performed at JPL by a joint ESA/JPL team.
