Duh me. Thankyou for the informative replies. I should have googled it I guess but it's 39C here and climbing...oh and it's Melbourne Cup day
so.
Why are science/techno boffins so fond of alarming catch phrases to describe routine, mundane events or issues? Bakeout, Catastrophic error, Illegal
operation etc.?
Sorry for being a smart arse. I look at the sun quite often, but had no idea what it meant.
It's a fancy term for sunbaking. Condensation builds up inside the satellite's cameras, and it interferes with the clarity of the picture, so they
heat it up to dry it out.
