external links date March 2011 The Planetary Data System PDS is a distributed data system that NASA uses to archive data collected by Solar System robotic missions and ground based support data associated with those missions. PDS is managed by NASA Headquarters Planetary Sciences Division. The PDS is an active archive that makes available well documented, peer reviewed data to the research community. The archive and data within are held to high quality standards established by the PDS. The PDS is divided into a number of science discipline nodes which are individually curated by planetary scientists. The Solar System Exploration Data Services Office at the Goddard Space Flight Center handles PDS Project Management. PDS archiving philosophy 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 ...

Although the geo prefix typically indicates topics of or relating to the Earth , planetary geology is named as such for historical and convenience reasons. Due to the types of investigations involved, it is also closely linked with Earth based geology. Planetary geology includes such topics as determining the internal structure of the terrestrial planets , and also looks at planetary volcanism and surface processes such as impact Impact crater crater s, fluvial and Aeolian processes aeolian processes. The structures of the giant planets and their moons are also examined, as is the make up of the minor bodies of the solar system, such as asteroid s, the Kuiper Belt , and comet s.
