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. The Mission of the STI Program is to support the advancement of aerospace knowledge and contribute to U.S. competitiveness in aerospace research and development. 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 NASA Technical Reports Server. The NTRS is a world-class collection of STI that includes over a million bibliographic records and a growing number of full-text documents. A public interface is available through the NASA Technical Reports Server (NTRS).
