NASA - HST degrades, little by little

e-mail "heads-up" from NASA; apparently chip 4 on the Wide Field/Planetary Camera(2) is on the fritz.
Probably defunct for any scientific purposes.

WFPC2 is mostly superceded by the Advanced Camera for Surveys, but not entirely. More to the point, it reminds us that things in space break, which is why refurbishing them can be a good idea.
If the refurbishing is properly funded, done expeditiously, and done well...
