10.0pt;font-family:Arial;color:navy'>This gives one the impression that RTT is
the only defining boundary on Cislunar space. There are other
characteristics for lunar programs besides RTT, so RTT should not be the only
defining parameter. Others could be lunar dust, mountain/crater rim blockage, a
certain pattern of AOS/LOS, Need to explain in the text in the scope section
that for this particular parameter, RTT, a 10 sec. RTT was chosen as the limit
that our solutions work for, and Cislunar solutions should work in other
environments (Mars Local) for mission spaces within 10 sec. RTT.</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Another open question… Should the
Mars Cislunar range go out to Sun-Mars L2? For a comm satellite that
covers the Martian far side? I assume that since Mars is lower mass than
earth, SML2 is closer to Mars than SEL2. But not being a celestial
mechanic, I’m not sure. If we feel lucky, we could put SML2 inside
the Mars blue circle, and if we’re wrong, or irrelevant, I’m sure
someone would tell us. </span></font><o:p></o:p></p>
