Ulysses

(yoo-liss -eez) A joint ESA/NASA mission to study for the first time the properties of the interplanetary medium and solar wind away from the plane of the ecliptic and over the polar regions of the Sun. The ESA spacecraft was launched by NASA in Oct. 1990, toward Jupiter. It encountered Jupiter in Feb. 1992, approaching close over the north pole then swinging under the south pole, and the gravity of the massive planet accelerated the probe out of the ecliptic plane into a polar orbit of the Sun; the inclination of its orbit to the ecliptic is in fact 80°. (No rocket has sufficient thrust to launch a probe directly into such an orbit.) It passed under the Sun's south pole in May 1994 and over the north pole in May 1995, crossing the ecliptic in Feb. 1995. Its nine scientific instruments took measurements throughout the mission. They measured the solar wind from the Sun's polar regions at both solar maximum and minimum, they studied the interplanetary magnetic field and found that the magnetic flux emanating from the Sun is the same at all latitudes, and they discovered ‘pools' of energetic particles surrounding the Sun. Ulysses also discovered the presence of interstellar dust in the Solar System, measured cosmic rays flowing into the Solar System, made the first measurement of interstellar helium atoms in the Solar System, and analyzed solar X-rays, radio waves and plasma waves, and Jupiter's magnetosphere. Ulysses' mission continued throughout the 1990s and early 2000s and was extended several times; the latest extension, announced in 2004, continued Ulysses' operation up to 2008.

They forgot all about their homes, and their wives and children, and all about Ulysses, and everything else, except this banquet, at which they wanted to keep feasting forever.
At last, when the swinish uproar resounded through the palace, and when he saw the image of a hog in the marble basin, he thought it best to hasten back to the vessel, and inform the wise Ulysses of these marvelous occurrences.
"Why do you come alone?" asked King Ulysses, as soon as he saw him.
Then he told Ulysses all that had happened, as far as he knew it, and added that he suspected the beautiful woman to be a vile enchantress, and the marble palace, magnificent as it looked, to be only a dismal cavern in reality.
"As I am your king," answered Ulysses, "and wiser than any of you, it is therefore the more my duty to see what has befallen our comrades, and whether anything can yet be done to rescue them.
But King Ulysses frowned sternly on them, and shook his spear, and bade them stop him at their peril.
"Fear not," replied Ulysses, "let no thought of death be in your mind; but tell me, and tell me true, why are you thus going about alone in the dead of night away from your camp and towards the ships, while other men are sleeping?
Ulysses smiled at him and answered, "You had indeed set your heart upon a great reward, but the horses of the descendant of Aeacus are hardly to be kept in hand or driven by any other mortal man than Achilles himself, whose mother was an immortal.
Ulysses then said, "Now tell me; are they sleeping among the Trojan troops, or do they lie apart?
Ulysses hung them up aloft in honour of Minerva the goddess of plunder, and prayed saying, "Accept these, goddess, for we give them to you in preference to all the gods in Olympus: therefore speed us still further towards the horses and sleeping-ground of the Thracians."
Ulysses from some way off saw him and said, "This, Diomed, is the man, and these are the horses about which Dolon whom we killed told us.
As he killed them Ulysses came and drew them aside by their feet one by one, that the horses might go forward freely without being frightened as they passed over the dead bodies, for they were not yet used to them.
