The SABIA-Mar (Spanish: Satélites Argentino-Brasileño para Información Ambiental del 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 along time and how it is affected and reacts to human activity.[3] It focuses on monitoring of ocean surfaces, especially studies of the ocean ecosystem, the carbon cycle, marine habitats, and mapping.[4][5]

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 be operated until 2021.[4][5]

By 2016, CONAE announced that an agreement had been reached, where Argentina would make SABIA-Mar 1, and Brazil would make SABIA-Mar 2. The Argentine satellite was supposed to fly in 2020.[6]

SABIA-Mar 1[edit]

SABIA-Mar 1 will be designed and built by the Argentine technological company INVAP. They will act as prime contractor, integrator and will supply two instruments. It is expected to be launched in 2020, have a 5-year design life and fly on a Sun-synchronous orbit with a four-day revisit frequency.[7] It successfully passed PDR on April 2016 which marked the end of Phase B development and the project thus entered Phase C, Detailed Design.[8] In April 2018, the Critical Design Review of the flight segment was approved.[9]

SABIA-Mar 2[edit]

SABIA-Mar 2 will be built in Brazil on the Multi Mission Platform the satellite bus developed for Amazônia-1. It will have a service module with a dry mass of 292 kg (644 lb) and a power budget of 304 Watts, and a payload module with a mass of 219 kg (483 lb) and a power budget of 260 Watts.[1]
