| Small Bodies Mission Support |
The Ulysses spacecraft, a joint endeavor between the European Space Agency (ESA) and NASA, was launched from the space shuttle in October 1990. It flew past Jupiter in February 1992 for a gravitational assist in getting to its final orbit, a polar orbit around the Sun. It subsequently flew over the south pole of the Sun in 1994, the north pole in 1995, and undertook a second solar orbit which brought it back to the solar poles in 2000-2001 during a period of maximum solar activity. The out-of-ecliptic orbit of the spacecraft has a period of 6.2 years. The mission has been extended until March 2008, to allow a third fly-over of the solar poles during 2007-8.
Although the primary objective of the mission is to study the properties of the heliosphere as a function of solar latitude, Ulysses also collects data concerning interplanetary dust, and studied the Jovian magnetosphere while flying past that planet.
The Ulysses Project web site is maintained by NASA/JPL.
The SBN, through its Interplanetary Dust Subnode and in cooperation with the Planetary Plasma Interactions Node, is the contact PDS node archiving the Dust Detector System data both in the encounter and cruise phases.
