, as well as ocean mapping. 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. The satellites, SABIA-Mar A and SABIA-Mar B, were supposed to fly in 2017 and 2018, and operate until 2021. By 2016, CONAE announced that a new agreement had been reached, where Argentina would build SABIA-Mar 1, and Brazil would build SABIA-Mar 2. The Argentine satellite, SABIA-Mar 1, is supposed to fly in 2024.

. They will act as prime contractor and integrator, as well as supply two instruments. It is expected to be launched in late 2024, have a 5-year design life, and fly on a sun-synchronous orbit with a four-day revisit frequency. It successfully passed PDR in April 2016 which marked the end of Phase B development, and the project entered Phase C (detailed design). In April 2018, the Critical Design Review (CDR) of the flight segment was approved.
