The SABIA-Mar (Spanish: Satélites Argentino-Brasileño para Información Ambiental del Mar, Portuguese: Satélites Argentino-Brasileiros de Informações Ambientais do Mar), originally called SAC-E by CONAE, is a dual satellite joint Earth observation mission.

The mission objective is to study the oceanic biosphere, its changes over time, and how it is affected by and reacts to human activity.

[5][6] This collaboration between the Argentine (CONAE) and the Brazilian (AEB) space agencies was originally supposed to make two identical spacecraft with Argentina supplying the payload and Brazil the satellite bus.

It is expected to be launched in late 2024,[1] have a 5-year design life, and fly on a Sun-synchronous orbit with a four-day revisit frequency.

[10] SABIA-Mar 2 will be built in Brazil on the Multi-Mission Platform (MMP), the satellite bus developed for Amazônia-1.
