SAC-A era un satélite pequeño (68 kg de peso) que sirvió como experiencia para probar sistemas ópticos, de energía, de navegación y de guiado de control. Transportado por el transbordador Endeavour, en la misión STS-88 en diciembre de 1998, llegó a exceder su vida útil de 8 meses sin presentar problemas técnicos.


The SAC-A mission, conceived as a technological model, as part of the SAC-C mission, tested a group of instruments developed within the country. It was also devoted to test both physical infrastructure and human resources of the telemetry, telecommand and remote control subsystem. The mission enabled professionals and technicians to get special training for the preparation of the ground control centers (hardware and software installation) and for the actual  control of the satellites.

SAC-A was a joint mission undertaken by Argentina (CONAE) and USA (NASA) space agencies under a framework agreement on a scientific and technical cooperation program with several years of previous development. The satellite specifications and design were provided by CONAE, as well as the planning, implementation and global coordination of the mission. CONAE was also responsible for the operation, telemetry, telecommand and control of the mission exercised at its Ground Station premises in Córdoba. The launch was carried out by NASA.
