That makes sense. Yep totally blown out.
You’d think they would have been more focused on these bright areas since they knew these features existed when the spacecraft imaged Ceres on approach long ago. I am surprised they didn’t shoot the target using several different exposures/filters etc. I think one of the cameras has 7 different filters, infrared mapping spectrometers etc.
Even at a distance of 45k kilometers back in February, these bright spots seemed extremely bright. Or were possibly captured using longer exposures back then as well.
You’re right, I would expect many different shots with various filters and exposures. Unanswered questions allow the buzz of speculation to grow.
