A servicing mission hasn't been set in stone yet - this next shuttle mission is still aprt of return-to-flight and there's still some way to go until they'll be happy flying the thing without ISS as a safehaven.

Hubble in trouble. But it seems there is still hope:

There is an article also from Sky&Telescope.
http://skyandtelescope.com/news/article_1750_1.asp In particular, they say: "Strangely, the power mishap might actually improve the quality of ACS observations, says Hubble senior scientist Dave Leckrone (NASA/Goddard). Mission managers have long wanted to lower the temperature of the camera's CCD detectors, but couldn't spare the time to recalibrate them. Now, since they must recalibrate anyway, they will be able to lower the temperature from –77°C to –81°C (–106°F to –114°F), which will reduce the background noise in ACS data by a factor of three". A factor 3 with only four ceg reduction seems too much but, if true, I'm disappointed that they didn't found time to do this before! -------------------- I always think before posting! - Marco -
