SUMMARY: The NASA/ESA Ulysses spacecraft's power is starting to run down, and soon it won't have enough to keep itself warm. When the spacecraft was first launched in 1990 to study the Sun, its reactor produced 285 watts of power, but now almost 14 years later, it's down to 207 watts. If it gets too much lower, the spacecraft won't be able to operate the heaters that keep the fuel flowing. Without this fuel, it won't be able to orient its main antenna towards the Earth to transfer data.

But still going strong after 15 years (http://www.spaceref.com/news/viewpr.html?pid=17993)


Fifteen years after its launch, the grand ESA/NASA Ulysses space mission is still going strong, orbiting the Sun and continuing to tell exciting stories about our nearest star.
...
n February 2004, ESA's Science Programme Committee approved the Ulysses mission extension until March 2008. With this, Ulysses will be the only mission to observe the heliosphere in three dimensions over a large fraction of the Sun's 22-year magnetic cycle.
