Nice to see something moving on the lunar surface again.



Looking forward to the selfies.


CCD imagers heated to 117 C typically do not perform very well, if at all. Active cooling of their imager is required and must always be monitored and regulated by the local and terrestrial computers. Their mission science must include active data feed as to all of their internal circuitry temps and methods of actively cooling. So, where is this mission critical data feed and their camera design/engineering specs?

Modern digital cameras can easily outperform conventional film DR(dynamic range) by at least 5 db (not to mention offering their much wider color spectrum sensitivity which can include IR and UV), providing an equivalent of 32 times better DR, and a truly advanced scientific CCD imager should easily obtain a 6 DB or 64:1 DR advantage over Kodak film (especially of individually recorded images at maximum resolution using an actively cooled CCD imager populated with at least 16.777 million pixels or photon buckets, as opposed to a video camera of only HDTV quality that’s not any better than what a retail consumer GoPro delivers). Problem is, these fancy imagers need to be kept relatively cool.

There are some really good CMOS and CCD imagers, not to mention newer better imagers of large area format from China:

Why wouldn’t they send their very best CCD imagers and camera optics to the moon?

Why are their cameras malfunctioning, or are they simply dysfunctional due to the heat?

Why are their gamma spectrometry instruments still not working? (is it too hot by day?)

What sort of special lens optics and narrow bandpass filters do each of their cameras have to work with?

Why are those local X-ray and gamma radiation readings not being recorded and shared with the world?

“ESTIMATION OF THE SURFACE TEMPERATURE OF FLAT AREAS ON THE MOON”
“A 1322.5 w/m2 change of the ESI would lead to 179.4K change in surface daytime temperature”

Perhaps imaging and other science via cool(179 K) planetshine or ESI should more than do the trick by offering up to 3.9 w/m2 illuminating upon the surface, offering plenty of working illumination inspite of their physically dark as coal surface. Combining of pixels offers the same benefit as having larger area pixels, such as with four times the low-light sensitivity and only a fourth the resolution is still offering an impressive 4.19 million pixel CCD image and still using large format optics doesn’t leave all that much to be desired, not to mention what a little bit of artificial illumination and especially of what the UV spectrum has to offer for the detection of all those secondary/recoil photons within our human visual spectrum.
