NASA Space Science Data Coordinated Archive
In 1966, the National Space Science Data Center opened its doors at Goddard Space Flight Center. The facility began as a physical repository for raw data from early space missions. Staff members handled 7-track and 9-track magnetic tapes by hand. They also processed various photoproducts generated by spacecraft cameras. All dissemination of this information relied on media replication and mailing. A researcher in 1980 might wait weeks to receive a reel of tape through the postal service. This slow process defined the center's first two decades of operation.
Starting in the mid-1980s, electronic networks began to carry increasing volumes of data. The center shifted away from physical mail distribution toward digital transmission protocols. By the present day, dissemination formats occur via the internet using HTTP or FTP. Web-based services now allow the general public to access selected imagery directly. Researchers can retrieve mission-specific information without waiting for physical shipments. This transition enabled faster analysis of solar physics and planetary science data across global institutions.
The NSSDC Master Catalog offers specific interfaces for querying different types of archived information. Users can search orbital, suborbital, and interplanetary spacecraft through the Spacecraft Query interface. Another tool allows queries for scientific experiments that flew aboard various space missions. Data Collection Query tracks collections currently held within the archive itself. Personnel Query provides locator information for individuals associated with past missions. Publication Query captures relevant bibliographies though these are not intended as comprehensive records. Lunar and Planetary Map Query lets users browse maps currently in stock at the facility.
NSSDCA operates as part of the Solar System Exploration Data Services Office. It resides within the Solar System Exploration Division at NASA's Goddard Space Flight Center. The Heliophysics Division of NASA's Science Mission Directorate sponsors the archive. Staffing levels have ranged between 15 and 100 personnel over the life of the center. These staff members include physical scientists, computer scientists, analysts, programmers, and data technicians. Civil service employees work alongside onsite contractors to maintain daily operations. The team collaborates with discipline-specific active archives to provide access to researchers.
Space science encompasses astronomy, astrophysics, solar physics, and planetary science. NSSDCA serves as the permanent archive for all mission data from these fields. The archive also holds data from some non-NASA missions and geophysical models. Specific services include the Multiwavelength Milky Way and the Multimedia Catalog. The NSSDC Photo Gallery displays selected imagery for public viewing. HEASARC handles high energy astrophysics while IRSA manages infrared science archives. LAMBDA preserves microwave background data analysis for legacy research projects.
