That sequence was shot at around 11:00 local time, so broad daylight. The bright pixels are hot pixels.
You can also tell by zooming into the image because these bright spots are basically just single pixels. Any real point source would always be imaged as at least a few pixels (the "point spread function"). You can see the local time (LMST) of those MSL pics here: http://lcdm.ca/msl/4106/index.2.html (And latest images here: http://lcdm.ca/msl/) |
