 and lunar science. As the permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and, in some cases, to the general public. NSSDC also serves as NASA's permanent archive for space physics mission data. It provides access to several geophysical models and to data from some non-NASA mission data.

NSSDC supports active space physics
Space physics
Space physics, also known as space plasma physics, is the study of plasmas as they occur naturally in the universe. As such, it encompasses a far-ranging number of topics, including the sun, solar wind, planetary magnetospheres and ionospheres, auroras, cosmic rays, and synchrotron radiation...

 researchers. Web-based servies allows the NSSDC to support the general public. This support is in the form of the photo gallery, cd-roms, photprints and through various other means. NSSDC online databases contain data about NASA, non-NASA data, spacecraft which generate space science data and experiments which generate NASA space science data. NSSDC information services are also involved in also data management standards and technologies.

NSSDC is part of the Solar System Exploration Data Services Office (SSEDSO) in the Solar System Exploration Division at NASA's Goddard Space Flight Center. NSSDC is sponsored by the Heliophysics Division of NASA's Science Mission Directorate. NSSDC acts in concert with various NASA Discipline Data Systems in providing certain data and services.

Overview

NSSDC was first established at Goddard Space Flight Center
Goddard Space Flight Center
The Goddard Space Flight Center is a major NASA space research laboratory established on May 1, 1959 as NASA's first space flight center. GSFC employs approximately 10,000 civil servants and contractors, and is located approximately northeast of Washington, D.C. in Greenbelt, Maryland, USA. GSFC,...

in 1966. NSSDC's staff consists largely of physical scientists, computer scientists, analysts, programmers, and data technicians. Staffing level, including civil service and onsite contractors, has ranged between 30 and 100 over the life of NSSDC. Early in its life, NSSDC accumulated data primarily on 7-track and 9-track tape and on various photoproducts, and all data dissemination was via media replication and mailing. Starting in the mid-1980's NSSDC received and disseminated increasing data volumes via electronic networks. Dissemination formats are presently via the internet, FTP, and disseminated on CD-ROM.

Astrophysics

Data Services contains data and mission information: The Multiwavelength Milky Way, the Multimedia Catalog and the NSSDC Photo Gallery.

Flight Mission Information contains lists of flight missions and information about them; this is where the NSSDC Master Catalog is along with mission-specific access. A graphical interface to mission information is in this area as well.

Related Information Services have detailed information about data held at NSSDC via the Master Catalog, NSSDC Lunar and Planetary Science, and NSSDC Heliophysics.

There are also NASA Astrophysics Data Archive/Service Centers. These include HEASARC (High Energy Astrophysics Science Archive Research Center), IRSA (Infrared Science Archives), LAMBDA (Legacy Archive for Microwave Background Data Analysis), MAST (Multimission Archive at STScI)
There are also other NASA archives/service centers; MSC (Michelson Science Center), NASA ADS (Astrophysics Data System)NED (NASA Extragalactic Database).

Heliophysics

Heliophysics contains data and information services, data archive, and service centers. Information also includes the Heliophysics Virtual Observatories.

Master Catalog

The NSSDC Master Catalog is available for the queries pertaining to information about data that are archived at the NSSDC as well as for supplemental information via the following query mechanisms:
  • Spacecraft Query. This interface allows queries to our database of orbital, suborbital, and interplanetary spacecraft.
  • Experiment Query. This interface allows queries for information about scientific experiments that flew on-board various space missions.
  • Data Collection Query. This interface allows queries for data that are tracked by NSSDC, primarily those that are currently archived here.
  • Personnel Query. This interface allows queries for locator information for personnel that were associated with various missions and/or data collections submitted to NSSDC.
  • Publication Query. This interface allows queries information about publications that are relevant to the data NSSDC archives or to the experiments and/or missions that accumulated the data. The publications so captured are not intended to be comprehensive bibliographies.
  • Lunar and Planetary Map Query. This interface allows queries of the lunar and planetary maps that NSSDC currently has in stock.
  • New and Updated Data Query. This interface allows queries for those data collections for which the NSSDC has recently acquired new data, either additions to existing collections or entirely new collections.
  • Lunar and Planetary Events Query. This interface allows queries for events that have occurred which are related to the exploration of the Moon and the Solar System.
