## Geosciences Node Overview

**Our purpose:**
**To archive and distribute data related to the surfaces and interiors of the terrestrial planets**** **
**To work with NASA missions to help them generate well-documented, permanent archives**** **
**To help planetary scientists find and use data of interest, providing tools and expert advice**

## Geosciences Node Data Holdings

- Currently the Geosciences Node hosts approximately 9 TB of data in 150 data sets from 19 missions, along with data from Earth-based and laboratory experiments.

## User Support: The Orbital Data Explorer

**ODE is a web-based tool for searching, displaying, and downloading orbital data sets for Mars**
**MRO CRISM, SHARAD, Radio Science, HiRISE, and CTX**
**Mars Express HRSC and OMEGA**
**Future additions: MGS MOLA, Odyssey GRS, others**
**Lunar version in preparation for LRO and other orbital lunar data sets**
**Available through the Geosciences Node MRO web pages, or directly at ****http://ode.rsl.wustl.edu/mars **

## User Support: The Analyst’s Notebook

**The Analyst’s Notebook is a scientist’s window into the archives for a surface-based mission.**
**Science data are integrated with planning and sequence information, engineering data, and documentation**
**Enables “mission replay” to show exactly how, when and why data were acquired**
**Currently available for Mars Exploration Rover archives**
**Future versions planned for Phoenix, MSL and Apollo surface missions**
**Available through the Geosciences Node MER web pages, or directly at ****http://anserver1.eprsl.wustl.edu/**

## International Activity

**IPDA (International Planetary Data Alliance) is working to set standards for sharing planetary archives among all national space agencies.**
**Mars Express: **
**We provide archiving advice to the PSA and data providers.**
**We maintain online copies of MEX archives for the convenience of U.S. users.**
**Kaguya:**
**The Japanese lunar orbiter Kaguya has an agreement with LRO to share altimetry data for planning purposes. Kaguya wanted to use PDS labels for this data, so we provided advice on label design.**
**GRUNT:**
**GRUNT is a joint Russian-Chinese mission to Phobos with many international participants (launch ~2011).**
**We will be the PDS point of contact for advice on generating PDS-compatible archives.**

## International Activity

**China:**
**Using Washington University funding, we established MOUs with Shandong University, Weihei, to host a PDS-compatible data system (including Chang’E-1 lunar observations) and with the Chinese Academy of Geological Sciences, Beijing, for cooperation in lunar science and Earth-analog studies.**
**The expectation is that we will establish working relationships with the Chinese planetary science community and encourage them to share their lunar data and to participate in archiving and planetary sciences on an international level.**

## Issues

**We are concerned about the long-term stability of all PDS archives.**
**It is difficult to deliver archives to NSSDC and to retrieve them. **
**Plans for offsite backups for disaster-recovery purposes are incomplete.**
**More resources should be applied to gauging and improving “customer satisfaction”. **
**User expectations of PDS have shifted from a purely archival function to a user service function.**
**Users need help finding, understanding, and using PDS archives.**
**We are responding by offering workshops (e.g., OMEGA/HRSC workshop at our node 5/21-23/08) and an increased presence at scientific meetings.**
**Missions are not producing the higher derived products that most users need to do scientific analysis.**
