New Space Needs a Mission

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Earth L-4 & L5 are unstable for objects beyond a certain size. Over that size it takes increasing amounts of Dv to keep the object there. This Dv is orders of magnitude less than what would be required for station keeping outside of a Lagrangian point.&nbsp; <br /> Posted by boris1961</DIV></p><p>What order of magnitude is "a certain size"?</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><span class="postbody"><span style="font-style:italic"><br /></span></span></p> </div>
