Jade Rabbit issues, is China in cahoots with our NASA?

“Jade Rabbit and our NASA DARPA taboo/nondisclosure moon”
If all goes according to plan, and Jade Rabbit cools off after sunset, there should be plenty of bluish planetshine and absolutely all sorts terrific camera and telescope images possible, and hopefully Jade Rabbit isn't going to be as colorblind as were most of our NASA/Apollo mission obtained images via Kodak film that supposedly had no environmental issues whatsoever.
Unfortunately, as is Jade Rabbit seems to be running in a mostly stealth or silent mode. Perhaps China isn’t willing to share how difficult surviving by day really is, even for modern robotics.
“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) EIS/planetshine that should more than do the trick by offering up to 3.9 w/m2 (full planetshine) illuminating upon the physically dark surface, offering plenty of even naked eye working illumination in-spite of their surrounding surface area that’s physically dark as coal. Combining of imager 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 full-color image and by still using large format optics doesn't leave all that much image quality to be desired, not to mention what a little bit of artificial illumination and especially given what the UV illuminated spectrum has to offer for the observation of all those secondary/recoil photons as detectable within our human visual spectrum.
Their previous mission:

100 megapixel CCD

“The camera, IOE3-Kanban, was developed by the Institute of Optics and Electronics under the CAS and is capable of producing images with 10,240 x 10,240 pixels, the statement said. Moreover, it is small and light, with its widest part measuring only 19.3 cm, the statement said, adding that it can be used at temperatures ranging from minus 20 degrees centigrade to 55 degrees centigrade.”
So, what happens to their CCD image quality or that of degrading its DR at 125+ C internal camera heat conditions? (it kinda tanks unless being artificially cooled)
What is their illuminated side temperature?
What is their daytime darkside temperature?
What amount of X-rays are being encountered?
What amount of gamma is being encountered?
Perhaps their real science is not going to start until after sundown, although more recent feedback information is telling us that Jad Rabbit is going to be shut-down for 15+ days of lunar night time, so apparently they have no significant onboard energy storage or thermal management capability, but at least they have those CCD imagers that operate w/o active cooling, and within spec at 125 C.
