<p>The <b>Planetary Data System</b> (<b>PDS</b>) is a distributed data system that <a href="NASA" title="NASA">NASA</a> uses to archive data collected by <a href="Solar_System" title="Solar System">Solar System</a> missions.

</p><p>The PDS is an active archive that makes available well documented, peer reviewed planetary data to the research community.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The data comes from orbital, landed and robotic missions and ground-based support data associated with those missions. It is managed by NASA Headquarters' Planetary Sciences Division.

</p>

<div class="mw-heading mw-heading2"><h2 id="PDS_archiving_philosophy">PDS archiving philosophy</h2></div>

<p>The main objective of the PDS is to maintain a planetary data archive that will withstand the test of time such that future generations of scientists can access, understand and use preexisting planetary data. The PDS tries to ensure compatibility of the archive by adhering to strict standards of storage media, archiving formats, and required documentation.<sup id="cite_ref-roadmap_2-0" class="reference"><a href="#cite_note-roadmap-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup class="reference nowrap"><span title="Page / location: 15">: 15 </span></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="Storage_media">Storage media</h3></div>

<p>One critical component of the PDS archive is the storage media. The data must be stored effectively and efficiently with no degradation of the data over the archive's lifespan. Therefore, the physical media must have large capacity and must remain readable over many years. PDS is migrating toward electronic storage as its "standard" media.<sup id="cite_ref-pdsarch_3-0" class="reference"><a href="#cite_note-pdsarch-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="Archiving_formats">Archiving formats</h3></div>

<p>The format of the data is also important. In general, transparent, non-proprietary formats are best. When a proprietary format is submitted to the archive (such as a <a href="Microsoft_Word" title="Microsoft Word">Microsoft Word</a> document) an accompanying plain text file is also required. It is assumed that the scientists of the future will at least be able to make sense of regular <a href="ASCII" title="ASCII">ASCII</a> bytes even if the proprietary software and support ceases to exist. PDS allows figures and illustrations to be included in the archive as individual images. PDS adheres to many other standards including, but not limited to, special directory and file naming conventions and label requirements. Each file in the PDS archive is accompanied by a searchable label (attached or detached) that describes the file content.<sup id="cite_ref-pdsarch_3-1" class="reference"><a href="#cite_note-pdsarch-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="Archiving_documents">Archiving documents</h3></div>

<p>The archive must be complete and be able to stand alone. There is no guarantee that the people who originally worked with and submitted the data to the archive will be available in the future to field questions regarding the data, its calibration or the mission. Therefore, the archive must include good descriptive documentation of how the spacecraft and its instruments worked, how the data were collected and calibrated, and what the data mean. The quality of the documentation is examined during a mission independent PDS peer review.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="Nodes">Nodes</h2></div>

<p>The PDS is composed of 8 nodes, 6 science discipline nodes<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> and 2 support nodes. In addition, there are several subnodes and data nodes whose exact status tends to change over time.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
