"High reflectivity?????? The albedo (reflectivity) of the moon is 0.07-0.11 (i.e. black as fresh laid asphalt). Not exactly "a high degree of reflectivity"."

I didn't say it is as reflective as a mirror or fresh fallen snow. But I can see from here that it's not as black as asphalt.
Still the usually quoted surface tempreture range is +200 degrees F. in the sun and -200 degrees F. in the shade. Nearby where I live we have beaches made of a unique type of sand. The sand is made of sphericly shaped grains of quartz. When the grans grind against eachother when you walk on them they squeek. The sand is also sugar white. But try walking across it bare foot at noon, it's hot. Also try touching a silvery chrome bumper in the sun just after noon, it's hot. As mentioned in the initial message, the spacecraft were in equatorial equivelent sunlight 24 hours a day for 5 days. To throw off that much heat by passive methods to the point of discomforting coldness goes against many design concerns I have heard of.
