What is the NTRS?

The NASA Technical Reports Server (NTRS) provides access to aerospace-related citations, full-text online documents, images, and videos. The types of information included are: conference papers, journal articles, meeting papers, patents, research reports, images, movies, and technical videos – scientific and technical information (STI) created or funded by NASA.

The NTRS integrates the National Advisory Committee for Aeronautics (NACA) and NASA collections. The NACA collection includes reports from 1900 to 1958 and the NASA collection includes documents created or sponsored by NASA starting in 1958 and continuing to the present.

The complete STI collection of NASA and non-NASA aerospace materials is available by registration only to U.S. Government civil servants, contractors, and grantees. This collection includes over 4.3 million metadata records and over 500K full-text documents. U.S. Civil Service, Contractors, and Grantees may fill out the NTRS Registration form for access to the complete collection of NASA STI.

By maintaining the NTRS collection, the STI Program supports NASA’s strategic goals to:

  1. Expand the frontiers of knowledge, capability, and opportunity in space.
  2. Advance understanding of Earth and develop technologies to improve the quality of life on our home planet.
  3. Serve the American public and accomplish our Mission by effectively managing our people, technical capabilities, and infrastructure.
