I have a new story posted over at ESA:

“The joint ESA/NASA solar mission Ulysses has forever changed the way scientists view the Sun and its effect on the surrounding space. The mission’s major results and the legacy it leaves behind have been presented today at ESA Headquarters in Paris, in view of the impending conclusion of the mission on 1 July 2008.”



I wrote three stories about this great mission for the farewell.  They can all be reached through here.


Or accessed individually here:


Sun to set on Ulysses solar mission
After over 17 years of operation, the joint ESA/NASA mission Ulysses will officially conclude on 1 July this year. The spacecraft, which studied the Sun and its effect on the surrounding space for almost four times its expected lifespan, will cease to function because of the decline in power produced by its on-board generators. …”

Ulysses: the science legacy
“During its 17.5 years in space, Ulysses has rewarded scientists with the unprecedented depth and breadth of its results. These have not just been about the Sun and its influence on nearby space. The mission has also provided surprising insights into the nature of our galaxy and even the fate of the Universe.

Ulysses: the engineering challenge
“If Ulysses had been human, with a life expectancy of 70 years, it would have just celebrated its 245th birthday, thanks to a dedicated ESA/NASA engineering team. In spacecraft years, the mission's life expectancy was five years. This turned into 17.5 years, 3.5 times what was envisaged.”
