kernels, are available from this website. You should carefully read about all three of these categories using the links below in order to find the data best suited to your needs. <p> If you are not already familiar with how to use SPICE data, take a moment to read about <a href="using_spice_data"> using SPICE data.</a> <p> It might be that a one-time effort to obtain some SPICE data will be sufficient for your science or engineering purposes. But be aware that, later on, new SPICE data might have been produced that would be of interest to you. We suggest you read <a href="keeping_current.html">Data Updates</a> to learn more. <p> Selecting the appropriate kernels to use in your work might be straightforward, or it might require careful thought. We suggest you read <a href="kernel_selection.html">Kernel Selection</a> to learn more. <p> A <a href=https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/Tutorials/pdf/individual_docs/34_naif_server.pdf>tutorial</a> regarding accessing all three categories of SPICE data is available from the NAIF server. <p> Insufficient or missing data is often the cause of a user's problem when trying to use SPICE. Take a look at this <a href="missing_data.html">note on missing data</a> for some pointers. <p> CAUTION: always download needed text kernels--do not CUT/PASTE the text kernel contents displayed in your browser into a text editor and save that as your text kernel. (CUT/PASTE may insert extraneous, unseen characters in your new text kernel that will render it unusable.) <p> All of this website's folders are <b>intentionally exposed</b> to facilitate the SPICE customer selecting the data, software and related materials needed for the job at hand. <p>Here is the <b>anticipated</b> <a href="https://pds.jpl.nasa.gov/datasearch/subscription-service/data-release-calendar.shtml">PDS schedule for upcoming data releases</a>. <p> <font color=#ef0000>All <a href="data_pds_archived.html"><font color="red"><b>"PDS Archived SPICE Data Sets"</b></font></a> are suitable for use in research programs proposed in response to NASA's DAP, ROSES and similar research opportunity announcements.</font> </td> </tr> </table>   </td> </tr> </table> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> <tr> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> <td width="730"><img src="images/spacer.gif" alt="" width="730" height="5"></td> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> </tr> <tr> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> <td width="730"><img src="images/pds_banner4.jpg" alt="PDS Menu" width="730" height="47" usemap="#pdsmenu" border=0></td> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> </tr> <tr align=center> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> <td> <table cellpadding="2" cellspacing="0" width="730" border="0" bgcolor="#cccccc"><tr> <td valign=center align=left width=110> <img height=70 src="images/spacer.gif" alt="" width=110 border=0></td> <td width=384 align=center>  <a href=https://www.nasa.gov/ target=_blank><font face="Arial, Helvetica, sans-serif" size="2">NASA</font></a> | <a href=http://www.caltech.edu/ target=_blank><font face="Arial, Helvetica, sans-serif" size="2">Caltech</font></a> | <a href=https://www.jpl.nasa.gov/copyrights.php target=_blank><font face="Arial, Helvetica, sans-serif" size="2">Privacy</a> | <a href=https://www.jpl.nasa.gov/imagepolicy/ target=_blank><font face="Arial, Helvetica, sans-serif" size="2">Image Policy</a> | <a href=https://www.jpl.nasa.gov/faq.php target=_blank><font face="Arial, Helvetica, sans-serif" size="2">FAQ</a> | <a href=https://www.jpl.nasa.gov/contact_JPL.php target=_blank>JPL Feedback</a> </td> <td width=219 align=right> <table align=right> <tr> <td align=left> <font face="Arial, Helvetica, sans-serif" size="2"> o Clearance: CL#05-2438<br> o Site Manager: <a href=mailto:boris.v.semenov@jpl.nasa.gov>Boris Semenov</a><br> o Webmaster: Ron Baalke<br> o Last Updated: <script>document.write( lastMod() );</script> </font> </td> </tr> </table> </td> </tr></table> </td> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> </tr> <tr> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> <td width="730"><img src="images/spacer.gif" alt="" width="730" height="10"></td> <td width="10"><img src="images/spacer.gif" alt="" width="10" height="1"></td> </tr> </table> <map name="pdsmenu"> <area shape="rect" coords="0,0,90,46" href="http://pds.jpl.nasa.gov" title="Planetary Data System Central Node"> <area shape="rect" coords="90,0,200,46" href="http://pds-atmospheres.nmsu.edu/" title="Atmospheres Node"> <area shape="rect" coords="200,0,296,46" href="http://pds-geosciences.wustl.edu/" title="Geosciences Node"> <area shape="rect" coords="296,0,428,46" href="http://pds-imaging.jpl.nasa.gov/" title="Imaging Node"> <area shape="rect" coords="428,0,562,46" href="http://pds-ppi.igpp.ucla.edu" title="Planetary Plasma Interactions Node"> <area shape="rect" coords="562,0,652,46" href="http://pds-rings.seti.org" title="Ring and Moon Systems Node"> <area shape="rect" coords="652,0,729,46" href="http://pds-smallbodies.astro.umd.edu/" title="Small Bodies Node"> </map>  </body>  </html>
