## Introduction

**The PDS Geosciences Node is leading the LCROSS archiving work for PDS.**
**Why we are here:**
**To introduce ourselves **
**Ed Guinness and Susie Slavney****Planetary Data System Geosciences Node****Washington University, St. Louis, Missouri**
**To introduce the Planetary Data System (PDS)**
**To talk about what goes into making a PDS archive**
**To answer your questions and help you get started**

## What is PDS?

**What is PDS?**

**The Planetary Data System’s job is to...**
**Provide help to NASA missions and other data providers to organize and document their digital planetary data.**
**Collect complete, well-documented planetary data into archives that are peer-reviewed.**
**Ensure the long-term preservation and usability of the data.**
**Make the planetary data available and useful to the science community.**
**Provide assistance to the science community in using PDS archived data.**

## What is PDS?

**What is PDS?**

**How PDS makes data available to the public:**
**Data archives reside at the PDS Nodes where they are maintained by scientists who use the data and who can provide expert help.**
**Almost all PDS archives are available online for downloading.**
**PDS provides online search tools to help locate data of interest.**

## Components of a PDS Archive

**Components of a PDS Archive**

**Required:**
**Data products with PDS labels**
**Index of data products**
**Documentation**
**PDS catalog information**
**Other documentation**** **
**Optional:**
**Calibration data and reports, used to understand how to generate derived products**
**Software to read the data, if needed **
**Extra material**
**Quick-look or browse versions of data**
**Analysis software**

**PDS Archiving**

## Components of LCROSS PDS Archives

**The LCROSS Science Team will submit 18 data sets to PDS:**
**Nine science instruments**
**1 Visible Context Camera, 2 Near-Infrared Cameras, 2 Mid-Infrared Cameras**
**1 Visible Spectrometer, 2 Near-Infrared Spectrometers**
**1 Total Visible Luminance Photometer**
**Two data sets per instrument**
**Raw data products **
**Derived (calibrated) data products**
**Data sets will include:**
**PDS-labeled data products**
**Index tables**
**PDS catalog information**
**Data Product Software Interface Specification**
**Archive Volume Software Interface Specification**

## Components of Ground-Based Observation Archives

**Because ground-based observations are not mission-derived, the archive requirements can be simplified.**
**Data products in PDS-preferred formats with PDS labels**
**PDS catalog information, including a data set description**
**If an observatory has archived data with PDS before, some information is already in the PDS catalog.**
**Additional documentation as needed**
**What are PDS-preferred formats?**
**PDS images as simple binary arrays, without proprietary headers or formats**
**FITS images are acceptable with some limitations**
**Tables in plain ASCII text (preferred) or binary**
**Peer reviews**
**Review data sets as a group, rather than a separate review for each one**

## What We Do With Your Data

**LCROSS ground-based observations will be considered a PDS Data Set Collection, all archived together at the Geosciences Node.**
**The collection will be available for downloading from our web site (**_**pds-geosciences.wustl.edu**_**).**
**The Orbital Data Explorer (ODE) search tool, now available for Mars orbital data, will be expanded to search lunar data including LRO and LCROSS. **
**Try ODE on Mars data at **_**ode.rsl.wustl.edu/mars/.**_
**To enable useful searches on LCROSS ground-based data, consider what common metadata should be included in each data set.**
