INVAP was the prime contractor for the design and construction of the SAC-C spacecraft and its main payload, the Multispectral Medium Resolution Scanner (MMRS), and all the Argentine on-board instruments: the High Sensitivity Medium Resolution Camera (HSTC), the High Resolution Technological Camera (HRTC), the Whale Tracking Experiment (WTE) and the Data Collection System (DCS).

SAC-C is the first Earth Observation Satellite in Argentina and the third in a series of science-oriented space missions within Argentina's Space Program. This mission is headed by CONAE within an international agreement of collaboration with NASA and the space agencies of Denmark, Italy, Spain, France and Brazil. The SAC-C Mission site is www.conae.gov.ar/sac-c/index.html

SAC-C provides data for the study of terrestrial and marine ecosystems, atmospheric temperature and water vapour monitoring. SAC-C determines variability in the ionosphere structure, providing space observatory quality measurements of the geomagnetic field and measurements of the long wavelength component of the gravitational field. The satellite also updates low orbit space radiation environment models.

SAC-C was placed on orbit on November 21st 2000 together with EO-1, on the first dual payload launch of a Boeing DELTA II rocket, from Vandenberg, CA, USA. The launch and early orbits campaign was conducted from the Mission Operations Control Center at Cordoba, Argentina in collaboration with a network of NASA and European Ground Stations.

SAC-C is fully operational and routinely delivering science and remote sensing data to users worldwide through Teofilo Tabanera Ground Station, Cordoba, Argentina.
