Lanzado en 2000, se mantiene actualmente en buen funcionamiento, a pesar de que se le estimaba un tiempo de vida de tan solo 4 años. Se trata de un satélite de observación de la superficie terrestre, de 485 kg de peso. Tiene como misión el monitoreo del ambiente y de catástrofes naturales. Los países asociados a esta misión son: Estados Unidos, Italia, Dinamarca, Francia y Brasil.


The SAC-C mission involves observations of the Earth, and several types of measurements for scientific purposes.

The observation of our planet, and of the Argentine territory in particular, comprises the assessment of soil and marine ecosystems by means of optical images.  As to the scientific assignment, SAC-C provides data on atmospheric temperature and water vapor content, magnetic field and long waves of the Earth gravitational field, and conduct studies on the structure and dynamics of both the atmosphere and the ionosphere.
