Am I correct?

The far side of the moon, which is always facing away from earth due to the fact that our moon is tidal locked, would be inherantly shielded from MOST (not all since there are satelites in space that are actually farther away then the moon) from the MULTITUDE of radiant EM output Earh produces (radio, microwaves, etc) No. both sides are NOT the same.

Higher frequencies could be heard via being bounced off of other objects, like planets or asteroids. But it would still be much quieter than any other permanent location in the solar system The radio spectrum up to aprox. 30 megahertz (AM radio and shortwave) would be able to be heard on the dark side of the moon fairly easily, but in much lower signal strength.

Hence, we on Earth can only see the same side (the nearside) of the Moon all year around, and never get to see the farside. So, in effect, from our perspective, you are in a way correct in saying that the Moon doesn't rotate (it just looks that way from Earth). Thus, putting a radio telescope on the farside of the Moon means that they would never actually come into line of sight of earth's interfering radio waves (not all, mind you). On another note, the moon's phases aren't caused by the Moon rotating at all, but are in fact produced by the position it is in its orbit around the Earth -- and, most importantly of all, its position relative to the Sun. For example, this month's total lunar eclipse is produced because the Moon's position will lie opposite that of Earth and the Sun (that is, the Earth will lie directly between the Moon and the Sun). So, Sunlight will be striking the Moon's nearside face 'nearly' head on (thus we'll see a full moon at first from Earth), before its orbit (the moon's orbit) then starts to move into the Earth's shadow. This kind of dance between the Earth, Moon and Sun is happenning all year around, which is why we only get to see the phases occurring every month as the Moon moves in its orbit and the Sun's light strikes it accordingly. Hope this helps? John - www.moonposter.ie To Jeysey Jim

The far side of the moon is the far side... It never faces earth. You can't see it from earth. This is why it can shield the radiotelescope. Man had the first glimp of this side in 1959 with the soviet Luna 3. Wrong. The far side of the moon is the far side… It never faces earth. You can't see it from earth.

Both sides of the Moon face the Earth the same amount of time as it rotates each lunar month (causing the Moon's phases). The "radio barrage" statement implies either that the Moon doesn't rotate or that being in the dark somehow protects the "far" side from the Earth's radio transmissions. Both of which are incorrect.
