	The Ulysses Solar Polar Probe
		The Ulysses mission is a joint mission with NASA and ESA to explore the solar environment at high ecliptic latitudes.
		In addition to its solar environment instruments, Ulysses also carries plasma instruments to study the interstellar and Jovian regions, as well as two instruments for studying X-rays and gamma-rays of both solar and cosmic origins.
		Ulysses is the first satellite carrying a gamma burst detector which went outside the orbit of Mars.

	Ulysses
		Ulysses has twice before orbited the Sun’s polar caps, first during a minimum in the number of sunspots and then when the sunspot number was at its maximum.
		During the first Ulysses orbit, the Sun’s magnetic poles were positive with outward fields in the north and negative or inward fields in the south.
		During Ulysses second orbit at sunspot maximum, the Sun’s polar fields disappeared and then reappeared with the opposite sense, negative or inward in the north and positive or outward in the south.

	Ulysses
		Ulysses is a solar probe launched in 1990 that has made the first-ever measurements of the Sun from a polar orbit.
		The primary objectives of the Ulysses mission encompass the properties of the solar wind, the structure of the Sun/wind interface, the heliospheric magnetic field, solar radio bursts and plasma waves, solar X-rays, solar and galactic cosmic rays, and the interstellar interplanetary neutral gas and dust, all as 3 function of solar latitude.
		In addition, Ulysses found a beam of particles from interstellar space that was penetrating the solar system at a velocity of close to 80,000 kilometers per hour (50,000 miles per hour).

	Ulysses - Science - Primary Mission Results
		Many models of the solar magnetic field used prior to Ulysses assumed that the solar magnetic field was similar to that of a dipole; field lines near the solar equator were thought to form closed loops whereas field lines from the poles were dragged far into interplanetary space by the solar wind.
		Ulysses found that the amount of outward magnetic flux in the solar wind did not vary greatly with latitude, indicating the importance of pressure forces near the sun for evenly distributing magnetic flux.
		Ulysses established that cosmic ray fluxes are not greatly enhanced in the polar regions because the cosmic rays traveling through the polar regions are scattered by large-amplitude magnetic waves (not shown in the figure) that Ulysses discovered in this region.

	Ulysses: What's New?
		Ulysses arrived over the sun's south polar regions for the second time in November 2000, followed by the rapid transit from maximum southern to maximum northern helio-latitudes that was completed in October 2001.
		The Ulysses data from the recent high-latitude passes, in addition to confirming the presence of large fluxes of energetic particles over the poles, have revealed that the absolute intensity of these particles in many events is comparable to that measured simultaneously in the ecliptic near 1 AU.
		Ulysses' state-of-the-art instruments were also able to show that the boundary between the fast wind and the slower, more variable wind from the equatorial regions is surprisingly sharp.

	space probe — FactMonster.com
		Instruments carried by space probes include radiometers, magnetometers, and television cameras sensitive to infrared, visible, and ultraviolet light; there also may be special detectors for micrometeors, cosmic rays, gamma rays, and solar wind.
		A probe may be directed to orbit a planet, to soft-land instrument packages on a planetary surface, or to fly by as close as a few thousand miles from one or more planets.
		The particulars of trajectory and instrumentation of each space probe are tailored around the mission's scientific and technological objectives; the data provided by a single space probe may require months or even years of analysis.

		These electrons follow the magnetic field lines from the sun, and their interactions with the plasma of the solar wind generate radio emissions called Type III radio bursts.
		Ulysses used a gravity-assist maneuver with Jupiter to rotate its orbital plane far out of the ecliptic, becoming the first spacecraft to go to high ecliptic latitudes (max 80¡) and over the poles of the sun.
		The field lines were found to be a spiral form, as had been predicted as a result of the outward solar wind and the rotation of the sun.

	ESA Science & Technology: INFO 13-1998: Ulysses comes full circle, before revisiting the Sun's poles
		Arriving in February 1992, Ulysses stole energy from the giant planet in a slingshot manoeuvre and was propelled back towards the Sun in an elongated orbit almost at right angles to the ecliptic plane, where the Earth and other planets circle the Sun.
		Ulysses is also a key member of a network of interplanetary spacecraft making observations of enigmatic bursts of gamma rays originating in the far reaches of the Universe.
		When Ulysses conducted the first-ever investigation of the high-latitude heliosphere, the Sun was quiet, being near the minimum of solar activity.

	Spaceflight Now \| Breaking News \| Officials seek to extend Ulysses sun probe mission
		Ulysses is a joint ESA/NASA mission and NASA's approval is also required for the mission extension.
		In the early years of this decade, during the declining phase of the previous solar cycle, Ulysses was en-route to Jupiter, and all measurements were made near the ecliptic (the plane in which the planets orbit) rather than at high solar latitude.
		The extension would also allow Ulysses to continue addressing a broad range of astrophysical phenomena, which include locating gamma-ray burst sources, studying the interstellar abundance of rare species like deuterium and 3He, and increasing the precision of cosmic ray isotopic abundance measurements.

	ESA Portal - Protecting the Environment - Ulysses returns to the Sun’s south pole and encounters blustery solar ...
		Conditions are very different from those Ulysses encountered during its first south polar pass in 1994 when solar activity, which is related to the magnetic behaviour of the Sun, was very low.
		At solar minimum, instruments on board Ulysses found that the fast solar wind, emanating from the Sun’s poles, blows at a steady 750 km/s and fills a large fraction of the heliosphere.
		Ulysses discoveries, however, have not been confined to the Sun and heliosphere.

	The Space Probe's Lethal Cargo by Karl Grossman
		The 1989 space probe, Project Galileo, is to contain 49.25 pounds of plutonium dioxide, most of that plutonium 238, its most radioactive isotope.
		So NASA devised a scheme in which the probe would first go to Venus and then be "slingshot" back toward Earth, which it would circle twice, making use of the Earth's gravitational field to increase the vehicle's momentum so it can reach Jupiter.
		And for Project Ulysses, whose mission is a north-south orbit of the sun, there is certainly plentiful solar energy.

		Helios 2 was slightly faster than its twin craft, and this probe still holds the speed record as not only the fastest spacecraft but also the fastest manmade object in history.
		Previous holders of this speed record included the European/NASA probe Ulysses, designed to study the Sun, that was launched at 34,450 mph (55,400 km/h) in 1990 and NASA's Pioneer 10 launched to Jupiter at 32,400 mph (52,100 km/h) in 1972.
		While this speed is faster than the probe's launch speed, it is still far from the maximum speed attained by both of the Helios vehicles.

	Spaceflight Now \| Breaking News \| Ulysses probe predicts weather at Sun's north pole
		As Ulysses passed by the south pole of the Sun a few months ago, scientists expected to find that magnetic lines were pointing outward, because observations from Earth show that the magnetic field has already reversed at the Sun's surface.
		As it studied the south pole during solar maximum, Ulysses saw energetic particles from many of the past year's solar flares, though they originated at the Sun's equator.
		Ulysses, launched in 1990, is a joint venture of NASA and the European Space Agency.
