The Geosciences Node is one of several discipline-specific nodes that make up the
Planetary Data System (see PDS Background). Our job
is to archive and distribute data sets that are relevant to the geosciences discipline,
which can be summarized as the study of the surfaces and interiors of terrestrial
planetary bodies. The Geosciences Node consists of the lead node at Washington University
in St. Louis and three data nodes, each responsible for a particular kind of data.
They are the TES Data Node at
Arizona State University, the GRS Data Node
at the University of Arizona, and the LOLA Data Node
We work with planetary missions to help ensure that their geoscience data sets are
properly documented and archived. For Mars missions, this interaction is facilitated
by the appointment of the Geosciences Node director, Raymond Arvidson, as the Interdisciplinary
Scientist for Data and Archives for the Mars Surveyor Program. We also restore and
publish data sets from past missions that are in danger of being lost. We provide
information and expert assistance to researchers on the data sets that we maintain,
and we are glad to answer questions from the interested non-scientist as well. For
more information, see References.
Our web site contains information about all of our data holdings, all of which can
be browsed online and downloaded. Data can also be distributed on other media on
request, if downloading is undesirable.
The Geosciences Node has a special interest in supporting the projects associated
with the Mars Surveyor Program, including orbiters, landers, and rovers. We also
provide support for archiving field tests of prototype landers and rovers.
