It will be necessary to establish agreements to ensure that these data are also properly curated and made accessible and that the formats and metadata standards are compatible. Dealing with these management challenges will require more than simply increasing funding to the active archives, although providing increasec!

assigned to manage these responsibilities is referred to here as the chief science information officer, or CSTO. This CSIO would cany out the following tasks: Provide strategic planning, oversight, and advice concerning the collection, processing, archiving, and dissemination of data and information collected by NASA's space missions.

NASA should assign the overall responsibility for oversight and coordination of NASA's data assets to a chief science information officer (CSIO) (or alternatively to multiple science officers)

Data Analysis Funcling The adequacy of data analysis funding for space missions has long been a concern of the scientific community.4 These concerns are summarized below.

According to a recent RAND Corporation report, which analyzed a set of small science missions, the resources devoted to scientific analysis averaged only I.6 percent of the total mission cost.' Given that targets for data analysis are generally an order of magnitude higher, it is unlikely that this level of funding achieved the maximum scientific return.

may have a role in shielding data analysis budgets from overruns that occur in missions after the non-advocate review is completed. While both senior reviews and nonadvocate reviews play important roles within NASA, neither is designed to address issues related to the overall budget or issues of balance across clisciplines, or between new missions, extended missions, and postmission data management.

However, as suggested by recent program solicitations in both the earth and space sciences, this situation may be changing. For example, proposals submitted to the OSS Explorer program and the ESE Earth System Science Pathfinder program must encompass all mission phases, inclucling concept study, definition and preliminary design, detailed design, development, mission operations, data analysis, data publication, and delivery of data and metadata to an appropriate archive.

Some federated data systems already exist: for example, the Planetary Data System and the Earth Science Information Partners (ESTPs)

The NVO will also take advantage of the development of grid technology, which is being widely embraced by many fields, including medical technology, earth sciences, high-energy physics, and astronomy. In fact, the inclusion of current grid technology in astronomy in the United States is being accomplished in large measure through the NVO.

While the astrophysics community is providing pioneering leadership in this field, other NASA-supported disciplines are beginning to explore ways of providing similar capabilities. For example, plans have also been developed for a prototyping study for a virtual solar observatory, modeled after the virtual observatory for astrophysics, and a recent senior review of the SunEarth Connection program recommended funding for the initiation of the virtual solar observatory.~° These plans are consistent with an earlier recommendation made by an NRC task group on ground-based solar research.

NASA should encourage efforts by the scientific community to develop plans for federations of data centers and services that would enable complex querying, mining, and merging of data from different instruments and missions in order to answer complex, large-scale scientific questions. · The National Virtual Observatory, an astrophysics project funded recently by the National Science Foundation (NSF)

From page 77... ...
NASA can become a leader in developing the techniques and tools for querying and mining large nonproprietary data sets. Playing this leadership role will require a new emphasis on software management, rigorous review of the balance between investments in software and hardware to optimize the science return from both individual missions and suites of missions; and development of new techniques for exploring and intercomparing data contained in a distributed system of active archives, data centers, and data services located both in the United States and abroad.
