SRI leads a multi-organization team to manage, operate, and maintain the Arecibo Observatory in Puerto Rico for the National Science Foundation (NSF).

SRI and its partners—the Universities Space Research Association (USRA), the Universidad Metropolitana (UMET) in San Juan, Puerto Rico, and the University of Puerto Rico (UPR)—bring extensive experience in facility management, space science, radio astronomy, and a wide range of high-power radar techniques. The team is expanding the observatory's cutting-edge science programs and applying their combined expertise to allow the observatory to become an ever-greater resource to the astronomy, planetary science, and space science communities.

Researchers in SRI’s Center for Geospace Studies and USRA are applying their atmospheric science and astronomy expertise as well as leveraging their science operations and management experience to enhance and develop observatory capabilities in radio astronomy, planetary radar science, and space and atmospheric science. UMET brings expertise in education, public outreach and facilities management, and covers site operations and public outreach activities. UPR is sponsoring joint faculty appointments and will develop education and research opportunities.

To advance research and education at the observatory, SRI and its partners are working with multiple Puerto Rican government agencies and private organizations to ensure close collaboration with educational and economic development institutions in Puerto Rico.

SRI's Center for Geospace Studies also operates, manages, and conducts research at the Sondrestrom Research Facility in Greenland, at Poker Flat in Alaska, and at Resolute Bay in northern Canada, through various NSF cooperative agreements. The Center is constructing additional high-power radars at Resolute Bay, in Argentina, and in other locations.
