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.

unreferenced date May 2008 article In planetary science , planetary differentiation is the process of separating out different constituents of a planetary body as a consequence of their physical or chemical behaviour, where the body develops into compositionally distinct layers the density denser materials of a planet sink to the center, while less dense materials rise to the surface. Such a process tends to create a Planetary core core and Mantle geology mantle . Sometimes a chemically distinct Crust geology crust forms on top of the mantle. The process of planetary differentiation has occurred on planets, dwarf planet s, the asteroid 4 Vesta , and natural satellite s such as the Moon . Heating When the Sun ignited in the solar nebula , hydrogen , helium and other volatile materials were evaporated in the area near the Sun. The solar wind and radiation pressure forced such low density material away from the Sun. Rocks, and the elements comprising them, were stripped of their early atmospheres, but themselves remained, to accumulate in protoplanet s. Protoplanets had higher concentrations of radioactive elements early in their history, the quantity of which has reduced over time due to radioactive decay . Heating due to radioactivity, impacts, and gravitational pressure melted parts of protoplanets as they grew toward being planet s. In melted zones, it was possible for denser materials to sink towards the center, while lighter materials rose to the surface. The compositions of some meteorite s show that differentiation took place in some asteroids. When protoplanets Accretion ...
