What is STI?
STI (scientific and technical information) is the collected set of facts, analyses, and conclusions resulting from scientific, technical, and related engineering research and development efforts, both basic and applied.


What is the NASA STI Program?
The NASA Scientific and Technical Information (STI) Program was established to support the objectives of NASA’s missions and research. It is dedicated to the advancement of aeronautics and space science. This program is essential to help NASA avoid duplication of research by sharing information and to ensure that the U.S. maintains its preeminence in aerospace-related industries and education. The NASA STI Program acquires, processes, archives, announces, and disseminates NASA STI and acquires worldwide STI of critical importance to NASA and the Nation.

The STI Program is a critical component in the worldwide activity of scientific and technical aerospace research and development. Collected from U.S. and international sources, STI is organized according to content prior to being added to the NTRS Registered, which is a world-class collection of STI that includes over 4 million bibliographic records and a growing number of full-text documents. A public interface is available through the NASA Technical Reports Server (NTRS).

The STI Program also manages STI contract support activities to acquire, organize, disseminate and preserve NASA STI.

NASA STI Program

  • Helps provide the widest appropriate dissemination of NASA research results
  • Is essential in helping the United States maintain leadership in aerospace
  • Provides a mechanism to help NASA avoid duplication of research dollars

STI Program as a critical component in the aerospace community

  • Collects STI from all NASA centers
  • Acquires STI from sources around the world
  • Maintains the largest collection of aerospace STI in the world
  • Provides worldwide access to STI that increases productivity and minimizes duplication of research

STI Program Mission

  • Supports the advancement of aerospace knowledge
  • Contributes to U.S. competitiveness in aerospace research and development

STI Program Components

  • NASA Headquarters STI (responsible for policy and oversight)
  • NASA’s Agency-wide program office, the Scientific and Technical Information Program Office, located at Langley Research Center, Hampton, Virginia (the STI Program Office is responsible for program implementation)
  • STI contract support activities
  • NASA STI Program at all NASA field centers


STI Contract Support Activities
These activities include to acquire, process, archive, announce, and disseminate STI. STI is input into the NTRS Registered, which contains over 4 million records. Records are indexed and digitized daily, and then added to the database in near-real time. Publicly available STI is also input into a public interface, the NASA Technical Reports Server (NTRS).
