PDS, a distributed archive, consists of Discipline and Support Nodes.

Discipline nodes represent traditional areas of scientific investigation and target their work toward one or more of the diverse user communities within planetary science, providing assistance for both data providers and users. (T14/Showalter is an example of discipline node service)

Support nodes provide expertise and ancillary information needed to interpret and preserve the data and for the integration of the PDS system.

Data nodes for specific instruments with large data volumes can be negotiated. The data structure must be compatible with PDS standards and node data is catalogued in and accessible through the PDS. The node contents are transferred to a discipline node of the PDS at the end of the mission.

The Planetary Data System (PDS)

4/25/07 4

Management duties are shared by a Program Manager, a Program Scientist and the Management Council (MC), composed of representatives from all nodes.

The MC communicates via face-to-face meetings, monthly scheduled telecons and structured emails.

PDS is tasked with supporting all missions of the Planetary Exploration Division and providing reliable and easy access to the archived data. This requires working with headquarters planners, proposers, instrument teams, missions and a broad spectrum of users.

PDS Management and Coordination

4/25/07 5

The PDS archives and makes available space-borne, ground-based, and laboratory experiment data from over 50 years of NASA-based exploration of comets, asteroids, moons, and planets. Many of the data sets are unique in that the observations cannot be duplicated.

Planetary missions frequently have short or intermittent observing phases that result in extended calibration phases possibly resulting in limited accuracy of calibration and an incomplete understanding of instrument stability and characteristics.

The archives include data products derived from a very wide range of measurements, e.g., imaging experiments, gravity and magnetic field and plasma measurements, altimetry data, and various spectroscopic observations.

The wide range of archival products and associated disciplines are fundamental reasons why PDS is organized as a confederation serving various science communities.

Characteristics of the PDS Archive

4/25/07 6

User desires and expectations are becoming more complex and demanding with time as data and mission complexity increase. They want and need derived products, rapid access, flexible search capability, refined catalogues, readily accessible data visualization, analysis, and cross-correlation tools.

Experienced users want interfaces with familiar data manipulation packages.

Inexperienced users are “Google” oriented but PDS data are not always adaptable to the expected level of indexing.

Interdisciplinary science requires parametric, geographic or spatial searches across missions, instruments and data sets.

Lack of reduced data records frustrate users who wish to find and download highly processed data at specific localities for further analyses, time intervals etc.

User and Customer Challenges

4/25/07 7

Users require that PDS supports heterogeneity for both technology and science -  tools that run on a wide variety of platforms and adapt for different uses. Users expect to be able to search all of the PDS data holdings within the system and perform correlated searches for products.They expect online access and distribution of all the data holdings and to download data products of increasing sizes.   

Mission loads require PDS be able to scale critical functions, storage infrastructure to support the increase of volume, architecture to support the complexity of missions with many types of instruments and operations to support the increasing number of missions occurring concurrently. 

Aging and obsolete technology must be refreshed to ensure long term usability of the data and the system.

Data in the archive must be periodically validated to ensure long term preservation.

Operational Challenges

4/25/07 8

Active or Planned Missions

4/25/07 9

Flagships, PI led Discovery and New Frontiers missions, and missions in the Mars Program present a wide range of challenges.

These challenges are amplified by the NASA policy to compete missions or instruments, bringing a constantly changing group of data providers to the PDS.

Combinations of NASA funded teams based at individual institutions, internationally supplied instruments and the ensuing variable funding and physical locations of the teams further complicate budgeting, planning and data ingestion.

Mission and Data Provider Challenges

4/25/07 10

Data volumes will continue to increase:

Mars Reconnaissance Orbiter will produce ~100 TB

Mars data volume is likely to be surpassed by that returned from the Moon in the next 10 years.

Missions, instruments and data are becoming more complex:

Rovers generate complex sets of products

Flagship Missions strive to satisfy many science goals leading to a variety of instruments, complex structure of data returned, and extended missions with reduced budgets for archive production

Mission and Data Provider Challenges(cont.)

4/25/07 11

Smaller or more focused missions present challenges:

The budget is limited and the funding profile differs from that used in initial design & planning

Mission phases are compressed and require rapid PDS response

PDS must supply tools to help with data archiving tasks, provide a Common Data Model, and participate as early as possible

Problem: Intrinsic problems of sustaining mission science and data analysis budgets sharply limit production and archiving of higher order products.

Mission and Data Provider Challenges(cont.)

4/25/07 12

History and ProgressIn the past the AOs did not include data planning requirements.

Proposers were not challenged to present cost-effective plans to produce data useful to non-team members.

Data pipeline planning was deferred until after launch.

By the point in the mission when PDS began its interface, most teams had a partially completed pipeline and resisted PDS needs and standards as “Creeping Requirements”. This led to many data formats, variable documentation and low level products.

Successful archiving requires PDS science node involvement from proposal briefing and assessment to user assistance and archive maintenance. Production of quality advanced products requires heavy involvement of Mission instrument scientists.

NASA Levels

Product Description

Raw Telemetry data stream as received at the ground station, with science and engineering data embedded.

Level 0 Instrument science data (e.g., raw voltages, counts) at full resolution, time ordered, with duplicates and transmission errors removed.

Level 1A Level 0 data that have been located in space and may have been reversibly transformed (e.g., calibrated, rearranged) in a reversible manner and packaged with needed ancillary and auxiliary data (e.g., radiances with the calibration equations applied). No resampling.

Level 1B Irreversibly transformed (e.g., resampled, remapped, calibrated) values of the instrument measurements (e.g., magnetic field strength).

Higher levels

Geophysical parameters mapped into uniform space time grids.

NASA Data Levels

4/25/07 14

“Data must be made fully public through the PDS, in a usable form, as soon as practical but no later than six months following its collection. Mars Scout teams will be responsible for collecting the scientific, engineering, and ancillary information necessary to validate and calibrate the scientific data prior to delivery to the PDS. Archival data products shall include low-level (raw) data, high-level (processed) data, and derived data products such as maps, ancillary data, calibration data (ground and in-flight), documentation, and related software or other tools necessary to interpret the data. All data products shall be documented, validated, and calibrated in physical units usable by the scientific community at large.” (Sec. 6.2.4)

Cassini as an Example of Complexity

4/25/07 16

Cassini - 12 instruments

with CDA & RADAR having 2 separate components Huygens - 6 instruments

International participation and multiple funding agencies involved in both teams

Cassini is an “old” mission -the AO did not require data planning and budgeting.

3 Years into primary mission - delivery of level 1a data has been exemplary - but few higher order data products were included in the Data Management Plan

The announcement concerning an 2-year extended mission is scheduled for early May

With the range of instruments, level of maturity of instruments and range of user needs - the answer is that they should be planned into the missions and produced by the instrument teams. How? See P7/Guinness.

The role of the PDS should be that of maintaining standards and providing assistance across Planetary Science.

In this framework the PDS in involved in the International Planetary Data Alliance (IPDA) to develop a core of standards, a data model, and tools that are used across the international planetary community. See P4/ Crichton.

Basic Problem - How Do We Get Higher-Order Products?

4/25/07 19

New Horizons (NH) has chosen to use FITS files - this is a PDS option.

According to the “FITS Myth” this would solve all our problems and make PDS data easily accessible to our users.

NH has a plasma package consisting of both the SWAP high-sensitivity solar wind monitor to address Pluto atmospheric escape objectives and the PEPSSI energetic particle spectrometer.

PEPSSI seems to be a simple instrument - flying by Jupiter, reading out its detector at specified times and storing the resulting parameters in a table, generating level 1 data that will be stored in the PDS for open user access.

How do we make Products accessible?

With the increase in the Mars Program and smaller missions, it has become apparent that imbedding PDS personnel within a mission is an effective way to insure that an efficient data pipeline is developed, but this does not assure higher order products.

Mission Data Management requires expert input to size and cost the data to ensure an adequate archiving budget.

PIs recognize this and many include a PDS-based individual, assigned with this task. Other missions negotiate this involvement.

Development of a data management plan during Phase A to scope the data management task should be a required component.

Imbedding PDS Personnel

4/25/07 31

Respond to an increasing spectrum of demands from a diverse and growing community of users

Interface with more than 20 missions at a time in various development phases

Ingest data from increasingly complex instruments

Educate data providers

Add non-mission data from individuals, laboratories and observatories

Provide useful links to related national and international data

Incorporate new storage/distribution technologies into preservation planning

Adapt to new modes of data access for users (animation

formats?)

Ongoing Challenges

Although many of these challenges are planetary oriented and efforts to face them are underway, the last two, in the form of reliability of archive media and an appropriate format for science animations, are topics that involve many of you.

I would propose that a valuable function of this group would be to identify mutual problems, define finite projects with a project leader, a working group and defined period for addressing the problem and reporting back to the participating group. In other words -- go for specific, identifiable accomplishments.
