The NVO was conceived to allow scientists to grapple with the enormous growth in astronomical data resulting from significant advances in telescope, detector, and computer technologies. What has resulted is a plethora of images, other data, and catalogs. In August 2001, the NSF allocated funding for a proposal entitled "Framework for the National Virtual Observatory". The grant was approved under its Information Technology Research program (since superseded). Current NVO funding supports collaboration to produce a distributed computing framework for an integrated cyber infrastructure for astronomers providing seamless access to these astronomical resources.
The manifestation of this infrastructure will be an operational “virtual observatory” available to scientists and to the public. Investigators acquire existing astronomical data from a variety of observatory archives through “virtual instruments”, that is, computer interfaces, tools, and services. The NVO is planned and implemented in synergy with the research community, the primary users of the system. In 2007, the operational stage of the NVO will begin with combined funding from NSF and NASA and programmatically executed through NSF. Scientists access the NVO through the NVO website.
The NVO development project is distributed across many institutions and includes teams at the Johns Hopkins University, California Institute of Technology, Space Telescope Science Institute, NOAO, Infrared Processing and Analysis Center, San Diego Supercomputer Center, and the Associated Universities, Inc. Affiliate organizations with participating teams include include Goddard Space Flight Center, Carnegie Mellon University /University of Pittsburgh, National Center for Supercomputing Applications, Smithsonian Astrophysical Observatory, USC, Fermilab, United States Naval Observatory, the University of Wisconsin-Madison, and National Radio Astronomy Observatory. The NVO, a US effort, has affiliates throughout the international astronomical community including IVOA, AstroGrid (UK), Euro-VO, the Japanese VO, the Australian VO, VO India and ten other national programs.
Along with its objective to serve the scientific community by enabling research through distributed data sources and services, the NVO intends to serve the public through educational and outreach resources on the VirtualObservatory Website The modest NVO Education and Public Outreach (EPO) effort is coordinated from Space Telescope Science Institute. The NVO provides technical support for the development of educational modules integrated into partner programs. NVO EPO coordinates activities with the international communities as well.
