The Telescopio San Pedro Martir project intends to construct a 6.5m telescope to be installed at the Observatorio Astronomico Nacional in the Sierra San Pedro Martir in northern Baja California, Mexico. The project is an association of Mexican institutions, lead by the Instituto Nacional de Astrofisica, Optica y Electronica and the Instituto de Astronomia at the Universidad Nacional Autonoma de Mexico, in partnership with the Smithsonian Astrophysical Observatory and the University of Arizona's Department of Astronomy and Steward Observatory. The project is currently in the planning and design stage. Once completed, the partners plan to operate the MMT and TSPM as a binational astrophysical observatory.
