The purpose of the Science Data Management Plan is to ensure that policies are in place to: (1) facilitate the generation of derived data products and analyses of those products by the Mars Global Surveyor scientists; (2) ensure that data illustrating new and exciting results are released for general use as soon as possible, using modern dissemination technologies; and (3) ensure that raw and processed data sets, together with appropriate documentation, are released in timely ways as structured archive volumes to the Planetary Data System for distribution to the NASA-supported science community and others. Note that the Planetary Data System acts as an agent for the National Space Science Data Center and as a primary interface to the Mars Global Surveyor Project with regard to transfer of archives.
The scope of this data management plan focuses on:
The Science Data Management Plan is intended to be consistent with the Mars Global Surveyor Project Data Management Plan. It also draws from Mars Observer documents. The Mars Global Surveyor Archive Generation, Validation and Transfer Plan is a companion to this document. It contains details as to archive volume generation, validation, and delivery to the Planetary Data System, along with a detailed plan for rapid release of new and exciting data and results via Internet postings and Press Releases. For reference, Table 1 is a glossary of terms used in this document.
The Mars Global Surveyor spacecraft will carry a camera, a laser altimeter, an emission spectrometer, a magnetometer with electron reflectometer capability, and a radio science experiment (see Table 2). The Mars Global Surveyor science community includes Principal Investigators, Interdisciplinary Scientists, Co-Investigators, and will include Participating Scientists (Albee et al. 1992). It also includes a Radio Science Team which utilizes both spacecraft and ground equipment to conduct experiments. The Radio Science Team consists of a Team Leader and Team Members. Roles and responsibilities for each type of investigator are given below.
Principal Investigators and the Radio Science Team Leader are responsible for the acquisition, reduction, and analysis of data from their instruments. They are also responsible for generation of standard data products and archive volumes for their instruments. Co-Investigators and Radio Science Team Members will be involved in these activities, as directed by the appropriate Principal Investigators and the Radio Science Team Leader, respectively.
Interdisciplinary Scientists will enhance science analyses by participating in reducing data for specific instruments, and/or by conducting analyses involving multi- instrument data sets to address specific science objectives. Table 3 lists the Interdisciplinary Scientists and their roles. They may also participate in acquiring Mars Global Surveyor data, primarily by leading efforts focused on acquisition of coordinated observations. Interdisciplinary Scientists will also lead most of the Science Working Groups as defined in Section II. E of this document.
Participating Scientists will be added during the Mars Global Surveyor operations and data analysis phase of the mission. Participating Scientists will fulfill Co-Investigator, Team Member, or Interdisciplinary Scientist functions during the Mission.
It is expected that the Interdisciplinary Scientists will chair Science Working Groups. These Groups will be composed of relevant Mars Global Surveyor scientists and will focus on coordinated data analyses. Other Mars Global Surveyor scientists will, from time to time, chair other groups to facilitate coordinated analyses. For planning purposes, it is assumed that there will be five groups to cover science (atmospheres, polar processes, atmosphere-surface interactions, geodesy and geophysics) and one to cover data and archives (Data and Archives Working Group, also known as DARWG). DARWG will be chaired by the Interdisciplinary Scientist for Data and Archives and will advise the Project on data acquisition, reduction, analysis, and archiving.
The Project Science Group will be chaired by the Project Scientist and will include Principal Investigators, and Interdisciplinary Scientists and the Radio Science Team Leader as members. The Project Science Group also includes the Mars Global Surveyor Program Scientist from NASA Headquarters and, by invitation, the principal interface for the Mars Balloon Relay Experiment. The Project Science Group will establish science and measurement strategies and also establish and coordinate cross-instrument and cross-discipline data analyses. The Science Working Groups (see Section II. E) are subgroups of the Project Science Group. The Project Scientist will track agreements for cooperative analyses among Mars Global Surveyor scientists and will, with the help of the Project Science Group, adjudicate any disputes that may arise.
Because of the expected widespread scientific and public interest in new results from Mars and the strong commitment of Mars Global Surveyor scientists to releasing data on a timely basis, it is important to establish clear release policies.
A cornerstone of the policy is the need for a reasonable interval of time to generate and validate standard data products and archive volumes before release to the general community. Based on experiences from the Magellan and Clementine missions, a six month period was necessary to produce useful products. At the same time, it is important to release significant data and findings immediately. MGS scientists are encouraged to validate and release data products as soon as possible, with the six month period considered to be a maximum for this mission (although certain data sets such as global maps may require more time to generate). Thus, the policy also defines a separate release of a significant subset of data, using modern technologies to reach a wide audience. The release policies are summarized as follows:
Public information release includes press conferences and written material concerning both mission operations and scientific analyses. Specific policy statements for Public Information Release for the Mars Global Surveyor Mission are:
The Planetary Data System has developed archive concepts that have been applied to Voyager data, Viking Orbiter Visual Image System Experiment Data Records, the Geologic Remote Sensing Field Experiment (GRSFE), Magellan radar mosaics and altimetry data, and the mosaics of Viking Orbiter images and elevation data to be used to support Mars Global Surveyor mission planning (Voyagers to the Outer Planets, 1988 through 1994; Mission to Mars: Viking Orbiter Images of Mars, 1991 through 1994; Geological Remote Sensing Field Experiment, 1991; Magellan: Mosaicked Image Data, 1991 through 1994; Mission to Mars: Digital Image Map, 1992, 1993). The concepts are straightforward and focus on archive collections as the logical assemblage of data objects, associated labels, documentation, metadata, and relevant software. Archive volumes are the physical volumes associated with relevant archive collections. For example, the GRSFE archive collection is located on 9 archive volumes (Geologic Remote Sensing Field Experiment, 1991).
Five Mars Global Surveyor archive collections are defined as part of this Science Data Management Plan. They correspond to the assemblage of standard products and associated information for each of the four instruments and the Radio Science Experiment. For reference, Table 4 shows the standard products to be produced by each instrument. A sixth collection corresponds to the SPICE data sets and associated NAIF software. A seventh is the assemblage of engineering products that need archiving, including raw science packet data. Table 5 summarizes the components of the various Mars Global Surveyor archive collections. Interdisciplinary scientists and others may also produce special products (or standard products) that are archived. These products and resulting volumes will be defined in the Mars Global Surveyor Archive Generation, Validation and Distribution Plan.
The Planetary Data System has developed a suite of templates that describe high-level information about a mission, spacecraft, instruments, and archive collections and volumes (Planetary Data System Standards Reference, 1994). The templates provide a high level view of a mission and its archives and are also used to populate a high level catalog operated by the Planetary Data System. The templates will be generated under the auspices of DARWG.
Each Mars Global Surveyor standard data product and archive volume (i.e., for each data object type and associated label) will have a Software Interface Specification (SIS) document. These documents will describe the high level contents of the products and details of the file structures. For science data packets and engineering data sets these documents will be written by Mars Global Surveyor Project personnel. For reduced data records, their associated files and documentation, and archive volumes, these documents are to be written by the relevant producer, with coordination by DARWG. For reference, an outline for an archive volume SIS is given in Appendix I.
Each Principal Investigator and the Radio Science Team Leader is responsible for providing algorithms and associated documentation and data, or published references to these items, that describe how science packet data for his instrument were converted to Level 1 data. Further, submission of documented software for generating Level 1 data products is strongly encouraged. The algorithms and software used to produce Level 1 standard data products should be available on the archive volumes that contain the relevant data objects.
Mars Global Surveyor data products will have labels that utilize a Standard Data Format Unit (SFDU) format. In addition, standard data products will utilize a combined SFDU/Planetary Data System Label. Label structures will be described in data product SISs.
Instrument raw science data will consist of data packets containing time-ordered sequences of observations obtained by a given instrument, together with engineering information that will allow Instrument Teams to check operation of their instruments. Science packet data will be compiled by the Mission Operations Team. The exact contents of science and engineering data will be instrument-dependent. The science packet data will be accessed by appropriate Principal Investigators and the Radio Science Team Leader (i.e., under Science Office cognizance) for data reduction. As noted, the Mars Global Surveyor Project office will produce archive volumes containing packet data and relevant engineering data.
Assuming 231 days spent at the 42K downlink rate and 456 days at the 85K downlink rate, a total of 64 gigabits is expected for the Magnetometer/Electron Reflectometer, 37 gigabits for the Mars Global Surveyor Laser Altimeter, 117.5 gigabits for the Thermal Emission Spectrometer, and 524.5 gigabits for Mars Global Surveyor Camera. The total number of gigabits expected is 743 (almost 93 Gbytes). The Mars Global Surveyor Camera numbers include the Mars Balloon Relay Experiment bits, but do not take compression of the Mars Global Surveyor Camera data into account.
Standard Data Products are those Level 1 and higher data objects generated from science packets and SPICE files, or from other data products. Standard Data Products will typically be generated from science packet data and SPICE data at instrument team facilities. Table 4 lists Standard Products for Mars Global Surveyor. The total volume is expected to be approximately 300 Gbytes. Standard Products are sometimes called operational products in other missions, since they are produced routinely using well-defined procedures. During the Mars Global Surveyor Mission it is expected that increased knowledge of instrument calibrations and operating nuances, together with increased knowledge of Mars and better understanding of how to process data, will result in updates to some Standard Data Products. Standard Data Products are the primary constituents of the archive volumes to be provided to the Planetary Data System.
Special Data Products are defined to be Level 1 or higher data products produced during the course of scientific research that are destined for transfer to the Planetary Data System. They are called Special Products as opposed to Standard Data Products because they are difficult to predefine and schedule since they will be dependent on the specific scientific content of Mars Global Surveyor observations. Special Data Products may be generated by Investigator Teams, Interdisciplinary Scientists or Participating Scientists. These products will typically be generated from Standard Data Products, although some may be generated directly from raw data (i.e., Level 0) using special procedures. In some cases the Special Data Products will be of general use to the Mars Global Surveyor community and will be delivered to the Planetary Data System.
Mars Global Surveyor will be the first Project to utilize fully the SPICE concept as a means of producing and accessing ancillary information needed to process raw science data (Acton, 1993). SPICE is an acronym used to describe five basic elemental data kernels:
S Spacecraft Ephemeris, providing spacecraft position and velocity as a function of time; P Planetary ephemerides and selected physical and cartographic constants;
I Instrument descriptions, including alignment offset angles, operations codes used in E Kernels, and instrument fields-of-view specifications;
C Inertial orientation of spacecraft primary coordinate systems and coordinate system rate changes;
E Event information, including nominal sequences, real-time commanding, unscheduled events, and experimenter's notebook uplink and downlink comments.
S and P kernels will be generated by the Navigation Team based on orbital tracking. The I Kernel will be generated by the Science Office (i.e., Instrument Teams). The C Kernel will be generated by the Spacecraft Team. The Data Administration Team will be responsible for generating E Kernels using inputs from the relevant teams.
Archival S and P files will be available on the Project Data Base 7 days after receipt of data from the Deep Space Network. I Kernels and the P Kernels will be generated and placed in the Project Data Base prior to launch of the Mars Global Surveyor spacecraft. These Kernels will be updated as needed.
Quaternians for generating C Kernel information will be updated each day. Software for utilizing the quaternians will be made available on the Science Operations Planning Computers. C kernels will be generated by the Mars Global Surveyor Project and will be made available via the project data base from time to time. It is assumed that E Kernels will take longer to compile since inputs from the Instrument Teams require examination of instrument status and science data. It is assumed that E kernels will be available on the Project Data Base 30 days from receipt of data at the Deep Space Network.
The SPICE data set collection will use NAIF tool kit software that will be delivered to the Mars Global Surveyor Project and will be available on the Science Operations Planning Computers. With this software, and algorithms/software for specific science packets and instruments, the SPICE Kernels can be used to convert science packet data to higher order data products.
The SPICE files will contain, particularly through the E-file (i.e., events file), many of the ancillary or engineering data sets typical of previous missions. However, there will still be a number of engineering data sets to be archived. These data sets will be archived by the Mars Global Surveyor Project Office.
Data are to be delivered to the Planetary Data System in the form of Archive Volumes. Archive Volumes are distributable units which contain a logical subset of an Archive Collection, together with labels and documentation.
Archive volumes will be assembled by the Instrument Teams and the Mars Global Surveyor Project Office. Principal Investigators and the Radio Science Team Leader are responsible for preparing each of the volumes derived from the products of their instruments. The Project is responsible for the science packets, SPICE and engineering volume preparation.
The Science Data Validation Team is responsible for reviewing the initial volumes. The Science Data Validation team will be chaired by an individual from the Mars Global Surveyor Science office, and will include the SDVT chief, the DARWG Interdisciplinary Scientist, one member from each of the instrument teams responsible for data quality assurance, the Data Archive Team representative, a Planetary Data System representative, and if necessary, the SFOC data administrator. After the review process is complete, the Mars Global Surveyor Project will provide funds for production (e.g., premastering of CD-ROMs) and distribution of volumes for use by the Mars Global Surveyor community. The Planetary Data System will provide funds for generation and distribution of volumes for the NASA supported science community once the volumes are released. The interfaces between the Mars Global Surveyor teams and elements of the Planetary Data System are summarized in Table 6.
For reference, Table 7 shows the teams responsible for generation of the relevant archive collection components. It is assumed that archive collection producers, working with DARWG, the Mars Global Surveyor Science Data Validation Team, and the Planetary Data System will do the detailed planning necessary to define archive collections and volumes in detail. It is further assumed that the Planetary Data System will take delivery of Mars Global Surveyor archive volumes at 6 month intervals, beginning in July 1998 and extending until July 2000. The last delivery is coincident with cessation of the Project Data Base after nominal mission operations (i.e., 2 year mission operations or 1 Mars year). Archive volumes containing standard products would be generated under the auspices of the relevant Principal Investigators and the Radio Science Team Leader. The SPICE, engineering and science packet volumes will be produced by the Mars Global Surveyor Project office. Detailed specifications of the schedules and responsibilities (including generation and validation) for each of these volumes will be included in the Mars Global Surveyor Archive Generation, Validation and Transfer Plan. For planning purposes, it is expected that approximately 650 compact disk archive volumes will be produced.

Term Definition Archive Collection refers to all of the Archive Volumes which make up a logical unit. For example, the Magellan Mosaicked Image Data Record Archive Collection contains 126 Archive Volumes. In turn, the Magellan Archive Collection includes the Magellan Mosaicked Image Data Record Archive Collection, the Magellan Altimetry and Radiometry Composite Data Record Archive collection, and others. Archive Volume distributable units which contain a logical subsets of an Archive Collection. An example of an Archive Volume from the Magellan Mission is Mosaicked Image Data Record CD- ROM# 120 (PDS CD-ROM ID# USA_NASA_JPL_MG_0120). Data Object a logical unit of data. An image or a spectrum are generic examples of data objects. Data Product a labeled grouping of one or more data objects resulting from a scientific observations (after Arvidson and Dueck, 1994). An example of a Data Product from the Magellan Mission is a single Mosaicked Image Data Record. Data Set a collection of data products.
