Lunar orbital decay is actually (to me) suprisingly fast. It is not of course due to drag, but the fact that there are asymetries in the moons gravitational field.<br /><br />It violates by "Star Trek" model for orbital decay for sure. <img src="/images/icons/wink.gif" /><br /><br />Yep, its been a long day...<br /><br />Wayne <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>

""Excursion" of LEM was dropped by NASA very early in the program because they did not like the sound of that word for a scientific program"<br /><br />True - I actually remember that from episode 5 of From the Earth to the Moon (Spider). <br /><br />Great series. I'm not sure if you can wear DVDs out, but I have sure tried with this set!<br /><br />

Perturbations of earth and sun on lunar orbiting craft would tend to crank up eccentricity of orbit too. Magnitude of the effect on a given orbit may not be large, but effects would be cumulative. Poynting Robinson effect for smaller objects would lower orbit, and magnetospheric interactions would be a small force too. For very small objects, pressure of sunlight can make a surprising difference, too.<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>
