[Laser] Re: another lunar experiment

[Tim Toast]

Here are some interesting pages that mention that in one
way or another - 
albedo:
http://jeff.medkeff.com/astro/lunar/obs_tech/albedo.htm

Mentions the 'subsolar point' being up to 30 percent
brighter. I guess with EME this would mean the point where
a signal originates on earth. For EME the most the phase
angle can be is only about 2 degrees?? - for stations
located on opposite sides of the earth.

The 1/D² law applies only on the returning way. The moon
has a  very poor albedo (max 0,2 in the Tycho area) and the
reflective properties are  lambertian...

Actually, the return will be somewhat better--the moon is
somewhat retroreflective.  There might be a 2x factor
improvement.  The reflectivity vs phase angle is
available--may some google searching could find it.
