<p class="MsoNormal"><span style="font-size:14.0pt">This program, originally authored by private citizen Chris Laurel, has been adopted by NAIF for SPICE-based and other enhancements in support of science and engineering functions in the solar system exploration
domain. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">Starting this Fall NAIF will have some resources to further enhance the Cosmographia program. We have some ideas about what to do, but we’re very interested to hear from you about suggestions that could make
Cosmographia better—whether by adding functionality or improving its usability. If you have any such ideas, we encourage you to send them in an email to NAIF management: charles.acton (at) jpl.nasa.gov. We can’t promise we’ll act on your suggestions, but
we will give them consideration.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">There is a variety of solar system geometry visualization software available throughout the community, with each package having its own niche; Cosmographia is just one such tool. It’s nice that folks can pick
the software that best suits their needs.<o:p></o:p></span></p>
