Spent Saturn stages locations?

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>

Ah yes - the shallow angle. Forgot about that. <img src="/images/icons/smile.gif" /><br /><br />Thanks SG!

I seem to understand shallow well...<br /><br /><img src="/images/icons/wink.gif" /><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>
