    Major changes are taking place in the way astronomy gets done. There are continuing advances in observational capabilities across the frequency spectrum, involving both ground-based and space-based facilities. There is also very rapid evolution of relevant computing and data management technologies. However, although the new technologies are filtering in to the astronomy community, and astronomers are looking at their computing needs in new ways, there is little coordination or coherent policy. Furthermore, although there is great awareness of the evolving technologies in the arena of operations, much of the existing operations infrastructure is ill-suited to take advantage of them. Astronomy, especially space astronomy, has often been at the cutting edge of computer use in data reduction and image analysis, but has been somewhat removed from advanced applications in operations, which have tended to be implemented by industry rather than by the end-user scientists. The purpose of this paper is threefold. First, we briefly review the background and general status of astronomy-related computing. Second, we make recommendations in three areas: data analysis; operations (directed primarily to NASA-related activities); and issues of management and policy, believing that these must be addressed to enable technological progress and to proceed through the next decade. Finally, we recommend specific NASA-related work as part of the Astrotech-21 plans, to enable better science operations in the operations of the Great Observatories and in the lunar outpost era

    Nurturing the Accumulation of Innovations: Lessons from the Internet

    The innovations that became the foundation for the Internet originate from two eras that illustrate two distinct models for accumulating innovations over the long haul. The pre-commercial era illustrates the operation of several useful non-market institutional arrangements. It also illustrates a potential drawback to government sponsorship – in this instance, truncation of exploratory activity. The commercial era illustrates a rather different set of lessons. It highlights the extraordinary power of market-oriented and widely distributed investment and adoption, which illustrates the power of market experimentation to foster innovative activity. It also illustrates a few of the conditions necessary to unleash value creation from such accumulated lessons, such as standards development and competition, and nurturing legal and regulatory policies.

    Innovation and the Evolution of Market Structure for Internet Access in the United States

    How and why did the U.S. commercial Internet access market structure evolve during its first decade? Commercial Internet access market structure arose from a propitious combination of inherited market structures from communications and computing, where a variety of firms already flourished and entrepreneurial norms prevailed. This setting nurtured innovative behavior across such key features as pricing, operational practices, and geographic coverage. Inherited regulatory decisions in communications markets had a nurturing effect on innovative activity. On-going regulatory decisions also shaped the market’s evolution, sometimes nurturing innovation and sometimes not. This narrative and analysis informs conjectures about several unique features of U.S. market structure and innovative behavior. It also informs policy debates today about the role of regulation in nurturing or discouraging innovation behavior.

    Workshop proceedings: Information Systems for Space Astrophysics in the 21st Century, volume 1

    The Astrophysical Information Systems Workshop was one of the three Integrated Technology Planning workshops. Its objectives were to develop an understanding of future mission requirements for information systems, the potential role of technology in meeting these requirements, and the areas in which NASA investment might have the greatest impact. Workshop participants were briefed on the astrophysical mission set with an emphasis on those missions that drive information systems technology, the existing NASA space-science operations infrastructure, and the ongoing and planned NASA information systems technology programs. Program plans and recommendations were prepared in five technical areas: Mission Planning and Operations; Space-Borne Data Processing; Space-to-Earth Communications; Science Data Systems; and Data Analysis, Integration, and Visualization

    Invest to Save: Report and Recommendations of the NSF-DELOS Working Group on Digital Archiving and Preservation

    Digital archiving and preservation are important areas for research and development, but there is no agreed upon set of priorities or coherent plan for research in this area. Research projects in this area tend to be small and driven by particular institutional problems or concerns. As a consequence, proposed solutions from experimental projects and prototypes tend not to scale to millions of digital objects, nor do the results from disparate projects readily build on each other. It is also unclear whether it is worthwhile to seek general solutions or whether different strategies are needed for different types of digital objects and collections. The lack of coordination in both research and development means that there are some areas where researchers are reinventing the wheel while other areas are neglected. Digital archiving and preservation is an area that will benefit from an exercise in analysis, priority setting, and planning for future research. The WG aims to survey current research activities, identify gaps, and develop a white paper proposing future research directions in the area of digital preservation. Some of the potential areas for research include repository architectures and inter-operability among digital archives; automated tools for capture, ingest, and normalization of digital objects; and harmonization of preservation formats and metadata. There can also be opportunities for development of commercial products in the areas of mass storage systems, repositories and repository management systems, and data management software and tools.
