Is there any news on Mars Global Surveyor more recent than:

?

It seems like there was a problem with the solar arrays, which could
imperil the survival of the spacecraft because the arrays are what
provides the power to run the thing, it entered safe mode, and I would
have thought that it probably would make it out of safe mode. Has it?

Don't see anything at http://mars.jpl.nasa.gov/mgs/

Now the good news is that there are 2 other orbiters already at Mars
(sounds like an argument for frequent missions to me).
