Every month there is a new moon. The moon isn't visible on this day. You've seen it before. That's how dark it would be.

Here is a table for various situations: The range ( ignoring dark polar crater) from 122C during the two week dat and at 0 latitude, to -158 at night. They probably did not take the cameras out unless within the range. It may be that the constituent parts of the camera would not work outside that range. Between the maxima and the minima there are ranges ...

You are right that $$\frac{T_M}{T_E} = \sqrt\frac{g_E}{g_M}>1,$$ which means that a pendulum period on the Moon is longer than the period of the same pendulum on the Earth. The rest, in my opinion, is just not precise enough. I think it is very confusing to use the early/late terminology when discussing two modes of operation of the same clock. I suggest ...

In your context, the second interpretation is correct. The fact is that falling objects accelerate both on Earth and on the Moon. The sentence is saying that the amount of this acceleration, regardless the source, is six times greater on Earth than on the Moon. In other words, things accelerate towards the surface of Earth six times faster than they ...

The leading theory for formation of the Moon is that a large object collided with the Earth and threw off a cloud of debris. This cloud then clumped together under it's own gravity to form the Moon. Simulations of the cloud show it formed outside the Roche limit - at around 1.3 times the Roche limit in fact. So the Moon has never been closer to the Earth ...
