When you have to kill a man, it costs nothing to be polite - Winston Churchill
It's unclear so far whether the problem can be fixed or not.
According to this web site, the space telescope imaging spectrograph (STIS) stopped after suffering a failed command echo check, and appears to be due to a failed inductor.
STIS is still in suspend mode, with
scientists analysing the problem and seeing if there's a way to fix it. Other instruments in the Hubble Space Telescope
appear to be functioning normally.
There's some more discussion on this topic on the Bad Astronomy web site. µ
